Boeing 787 Dreamliner

The Boeing 787 Dreamliner additional name, is a twin-engine long-range airliner of the U.S. aircraft manufacturer Boeing for 200 to 300 passengers. It is the successor to the Boeing 767 and the first widebody aircraft, whose fuselage is in large part made ​​of carbon fiber reinforced plastic. The first machine was delivered after three and a half year delay 25 September 2011 on All Nippon Airways. On 26 October 2011, the 787 at this airline first went into service.

History

Prehistory

Boeing had brought the pattern 777 last mid -1990s, a new aircraft to market.

Since the late 1990s, Boeing pursued different strategies to respond to the challenge by Airbus and its development of the world's biggest passenger plane, the A380, First, wanted to Boeing, which with the developed in the 1960s, 747 the hitherto largest passenger aircraft had in the program, make it through an extra large version of the " jumbo jet " 747 -X Airbus A380 direct competition. This plan was, however, due to lack of demand from airlines soon abandoned and replaced by the announcement, to develop a sound almost fast large aircraft "Sonic Cruiser". It was assumed at Boeing, maximum time savings remain the determining factor in the airline business.

The crisis following the attacks of 11 September 2001 and in the face of rising oil prices but no airline was willing to order the true fast, but relatively inefficient Sonic Cruiser. Because of these reactions, Boeing set out to design from the initially intended only as a reference design of a " Super Efficient Airplane" a new aircraft - the Boeing 787 First, the aircraft was renamed as " 7E7 ", with an "E " for " efficient"; After starting the program, it was officially renamed in 787, to better fit into the scheme digits of the company and about an Asian auspicious "8" to have in their names. In addition, they gave the 787 the nickname " Dreamliner ", which means something like dream aircraft.

The decision to build the 787 precipitated the Boeing board in December 2003, which had been already calculated in advance: General was felt before that Boeing it could not afford not to build an advertised model in a row for the third time.

Boeing now sees the future more in medium-sized models as in Boeing 747 patterns that also less major airports away from the aviation hubs can be flown directly and without stopping long and ultra long haul (Point-to - Point) and the aviation hubs with the smaller machines can be serviced more frequently. Boeing expects that the well- paying business travelers rather want a less cost savings due to a particularly large aircraft a short wait until the next flight or connecting flight to the transfer. In addition, an enlarged version of their classic was introduced on the market with the 747-8.

A goal of the developers of the 787 was, the operating costs - mainly due to the lower fuel consumption - bringing to eight to ten percent below that of the Boeing 767 -300ER to. On 7 November 2006, the manufacturer announced that the direct operating costs due to lower maintenance costs would be reduced by a further two to three percent. This cost advantage is, according to Boeing, the higher initial cost of 787 more than compensate.

Financing and subsidies

The launch cost of 787 totaled about 13.4 billion U.S. dollars, the Boeing itself ( about 4.2 billion U.S. dollars ) from suppliers ( 3.1 billion U.S. dollars), the government subsidy to by involved in the manufacturing countries ( Italy 590 million U.S. dollars, Japan 1.588 billion U.S. dollars), of the U.S. states of Kansas ( 200 million U.S. dollars) and Washington ( 3.2 billion U.S. dollars) and other donors are applied. This corresponds to about twice the 1990 for the launch of the Boeing 777 (6-7 billion U.S. dollars) needed funds.

The alleged violations of the " Agreement on Subsidies and Countervailing Measures " of the World Trade Organization ( WTO) established subsidy schemes in the financing of 787 led in 2004 to a complaint by the EU to the WTO.

Program start

The official program launch of the Boeing 787 Dreamliner took place on 26 April 2004, after All Nippon Airways ( ANA) had ordered the first customer to fifty machines fixed for delivery from 2008. This applies to the versions 787-3, -8 and -9. The version 787-10 is yet unconfirmed by Boeing. The date for the planned rollout was announced on 30 March 2007 and finally took place on 8 July 2007 at Endfertigungswerk place in Everett (Washington).

Similar to the production model of Airbus are essential parts produced at different locations and taken to the main assembly. Unlike Airbus, these components are not manufactured in different plants of the company or the parent company, but by independent contractors. The wings are manufactured by Mitsubishi Heavy Industries in Nagoya, Japan, the tailplane by Alenia Aeronautica in Italy ( in cooperation with the Turkish TAI ), single hull sections also by the aforementioned manufacturers and the Lewis and Vought Corporation of South Carolina and Spirit AeroSystems of Wichita (Kansas).

The first unofficial roll-out took place in late June 2007, when a Boeing 787 was towed from the production halls, the official was followed on 8 July 2007 ( the date writes Boeing according to American spelling as 7/8/7 ), as the 787 on Boeing's flight shipyard in Everett was presented to the world public.

Was successfully completed on 20 June 2008 as an important step before the first flight of the first power-on ( power on ) the electrical systems.

The first flight took place on 15 December 2009 from 10:28 clock (local time ) or 19:28 clock (Central European time ) by a 787-8 and instead resulted from Paine Field in Everett, near Seattle in Washington state to Boeing Field on the southern edge of the urban area of ​​Seattle. Given the original timetable, this was a delay of 27 months. The three-hour flight was performed by test pilot Mike Carriker and the Randy Neville, the machine ( were approved 4572 m) a maximum height of at least 3764 m and a speed of 370 km / h reached.

At the Farnborough Air Show in the Dreamliner landed 18 July 2010 for the first time in Europe. The first visit took place in Germany on 25 June 2011 a presentation of the German launch customer Air Berlin on the Berlin-Tegel Airport. With a machine of the Polish state airline LOT landed at the airport Wien- Schwechat on 17 December 2012, the first Dreamliner in Austria.

Class records

As part of a test flight on December 6, 2011 Dreamliner ( Registration ZA 006) with 13 people on board, including six pilots, two records for aircraft in its weight class could set ( 200-250 tons ): a distance record for covering a distance of 19,835 kilometers without refueling and a time record of 42 hours 27 minutes to orbit the Earth. The first part introduced the plane from Seattle to the east across the Atlantic, the Mediterranean, the Middle East and India 19,835 km to Dhaka, Bangladesh. During a two-hour stop there, the machine was refueled. Then she flew in an easterly direction over Singapore, the Philippines and the Pacific Ocean 18,678 km to Seattle, where they landed 42 hours and 27 minutes after the start again. In order for the Dreamliner broke a seven- year-old distance record, an A330 - a time record for a circumnavigation of the world, there was not yet in this weight class.

Technical innovations

The fuel consumption is expected to decline by 20 percent by newly developed engines, reduced weight and better aerodynamics than comparable current models, the dependent under real conditions of seating, use, and utilization have specific consumption 3-10 l/100 km / passenger. In addition, the new engines will cause less noise.

Manufacturing and logistics

A special feature of the 787 is the globally distributed production of modules that are fully equipped from suppliers. While the wings ( by Kawasaki Heavy Industries and Mitsubishi Heavy Industries ) and individual body parts ( center wing box of Fuji Heavy Industries / Nagoya, front torso portion and the main landing gear bay of Kawasaki Heavy Industries / Nagoya ) are produced in Japan, come other parts of Italy ( central body part of Alenia in Grottaglie, tailplane of Alenia Foggia ). Boeing itself is limited to final assembly, are mounted at about four prefabricated components and engines and interiors in a few days. Boeing Thus understood on this aircraft only as a system integrator.

The advantages of this mode of production is one that risks and costs can be transferred to the suppliers ( sales -related payment of suppliers and complete takeover of once for development and production costs ). The disadvantage is that the dependence increases from suppliers and goes at Boeing lost know- how for the next aircraft developments.

Specially created a new type of aircraft - for the transportation of the parts was the 747LCF - a modification of the 747.

Problems

Technology

Since Boeing prior to the development of the 787 had very little experience with fiber composite components, in particular problems were foreseen in the manufacturing process. In the previously developed Boeing 777 compared to the Airbus aircraft ( A340/A330/A320 ) relatively few fiber composite components were used. The first signs of trouble gave reports of blistering in fiber laminate in the hull production.

In May 2009, occurred in a load test of the wing delamination of the composite materials at the end of the wing stringers, which led to a further shift of the first flight. Boeing wants to solve the problem with additional reinforcements.

On August 15, 2009 announced that wrinkles were discovered in the outer skin of 23 segments of property under construction aircraft. These segments were produced by the Italian supplier Alenia Aeronautica. Upon discovering these problems, the production was stopped by the supplier to resolve the problem.

Schedule

As early as 2006 have been reports of problems to be able to meet the schedule. The reasons for this subject, in addition to the confirmed problems in the production of short segments in problems with the bearing surfaces ( with respect to production and high weight ) and the integration of electronics. In addition, it should have given each other at this time trouble communicating with the program due to many suppliers, as well as in the coordination of suppliers. On 11 December 2006, Boeing confirmed the adherence to the timetable according to which the 2007 test flight of the first aircraft is planned to 2008, the first should be delivered.

The speculations were confirmed in 2006, when Boeing announced on 5 September 2007 in a telephone press conference, having to move the first flight to mid-November to mid-December 2007. It was thought at that time that, due to a tightening of the test program, the planned first delivery in May 2008 would continue to be possible, which had to be revised on 10 October 2007, it was announced by an official declaration that the first flight on March 2008 and the extradition shifts to December 2008.

On January 16, 2008, Boeing further delays, according to which the first flight put off until the end of the second quarter 2008 and the first delivery to the first quarter of 2009. This date could also not be kept, and it was a maiden flight aimed at the end of 2008 and a start of deliveries for the third quarter of 2009.

In the following years it was not thought a few of the newly defined internal project deadlines and had to make further improvements in our manufacturing processes. On 9 April 2008, Boeing finally announced a further delay. The first flight was therefore scheduled for the fourth quarter of 2008, while the first delivery should take place in the fourth quarter of 2009. The result is compared to the original schedule, a total delay of the project by about 18 months. With the new schedule, Boeing announced also that the order in which the three previously announced variants will come onto the market, has changed. The base model 787-8 is now not the 787-3, but - in 2012 - followed by the 787-9. The -3 variant therefore should be delivered only as the third; a date was not mentioned.

On 4 November 2008, Boeing finally announced that is no longer to be expected with the first flight of the Dreamliner in 2008. The reason for the recent delay were problems with connecting parts ( six percent of the special bolts for connection of titanium and composite parts do not close flush ) and named a lengthy strike mechanic. On December 11, the new schedule was concretized: The first flight should now take place in the second quarter of 2009, the first delivery in the first quarter of 2010.

On June 23, 2009 Boeing announced that the first flight due to technical problems again - 'll move - for now indefinitely. The basic problems were referred to the fuselage side. This should now be strengthened.

On August 27, 2009 Boeing announced a new " schedule " known. After the first flight of the base model 787-8 should be held in late 2009 and the first delivery in the fourth quarter of 2010.

At the date of the first flight, there was no further shift, this took place on December 15, 2009.

In mid-July, 2010, Boeing announced that the first machine delivery to the Japanese company could move All Nippon Airways at the beginning of 2011. The reason for the delay, among others, further investigations were mentioned in the testing phase of the aircraft. On 27 August 2010, confirmed that the first 787 now expected could only be delivered in February 2011, as delaying the provision of the Rolls- Royce Trent 1000 engines after a failed test run and related necessary corrections.

In early December, 2010, Boeing informally compared to managers of Air France that the first deliveries " in the June or July 2011," would so move to another six months. On 18 January 2011, Boeing finally announced publicly that the first delivery would be definitely shifted in the third quarter of 2011. Overall, the delay is compared to the original plan for three years.

On 26 May 2011, Boeing announced that the first delivery will take place from August to September 2011. Recipient of the first aircraft will be the Japanese airline All Nippon Airways ( ANA).

On August 13, 2011, the flight test program of the seven machines used for this purpose was completed after 1731 flights and 4911 hours of flight time.

On September 25, 2011 finally the first delivery of 787 took place. Customers were as predicted All Nippon Airways. On October 26, 2011 Finally, the company was taken with the 787.

After January 16, 2013, the U.S. aviation authority FAA had the Boeing 787 is for the USA with a start prohibition and this other regulators were followed, Boeing stopped on 18 January 2013, the delivery of the aircraft ordered. The production but should be continued. More about the grounding section incidents.

Weight

On 7 November 2006 it was announced that the draft was still about 2.5 tons ( two to three percent of the tare weight ) should be easier to meet the promised performance. This will be achieved through minor optimizations and through increased use of titanium. To this end, the research and development budget in 2006 was raised to 300 million U.S. dollars in 2007 and again to 335 million U.S. dollars.

The first six prototypes of the model to be built by Boeing Information of 11 December 2006 with obesity. From the seventh plane then the target weight is to be respected.

Steven F. Udvar- Hazy, chief of the leasing company ILFC, criticized the 787-9 is more than six tons too heavy. " We are working on weight reductions for the 787-9 as well as other members of the 787 family," confirmed by the manufacturer.

In December 2009, Boeing published a revised version of the airport planning documents for the 787, resulting from the increase of the maximum take-off weight for all three variants, which are partly due to the increased curb weight. The maximum take-off weight of the 787-3 is now 170,250 kg (plus 5000 kg ), which the 787-8 227.9 thousand kilograms (plus 8400 kg ) and the 787-9 247.4 thousand kilograms (plus 2270 kg ).

The relatively small increase in weight of the 787-9 is due to the fact that the span of the Boeing 787-9 to 787-8 of the measure decreased after an analysis of the results of the load bearing surfaces of the 787-8 was present.

11 May 2011, Boeing announced a further increase in weight of the 787-9 known to now 251,000 kg. This means that the maximum take-off weight increased compared with the original plan to 5,800 kg.

On 4 October 2011, further details about the preponderance of the 787-8 were known, the prototype weighed nearly ten tons more than originally planned; the first customers machines ( 7 to 19 of delivered copy ) will still go with 6.1 tons of excess weight in the service of the respective airlines. It was not until the 90th Boeing machine will be able to meet your specifications reach the promised weight, up to that permanent weight reductions are planned. At least until the 34th copy of the empty weight is but four tons higher than the planned weight.

Supplier

On February 2, 2007 it was announced that Boeing has problems with suppliers Kawasaki Heavy Industries and Fuji Heavy Industries. This could not finish the work on the components for the 787, so the semi-finished parts had to be taken to a Boeing plant in South Carolina. On 12 June 2007 were known problems with the fit. To connect the front part of the first prototype with the rest of the fuselage, internal baffles had to be removed to make it less stable, so that they could fill a gap of 4.5 cm with hydraulic assistance. In the time allotted for the rollout machine only temporary rivets were due to delivery difficulties initially be installed in many places that needed to be replaced before the first flight.

Software Problems

August 9, 2007 it was announced that because of the software, the first flight of the Boeing 787 had to be moved from the planned date in September to October 2007. Compliance with the rest of the schedule was still possible.

Engines

In December 2007, doubts arose whether the engines from Rolls- Royce in particular can adhere to the promised fuel economy. On 16 September 2010 it was announced that problems with an engine of a test aircraft had occurred. The engine had to be replaced. It was unclear whether this incident will have an impact on the timing of delivery. The Boeing 787 has reached an ETOPS -180 approval in the test flights so that aircraft have to take three hours to reach an alternate airport after engine failure.

Board electrics

During the certification flights took place on Electrical Panel P100 of ZA002 in the rear electric space to fire. In the investigation the Panel molten metal was found. The incident led to an interruption of the certification program. At the design of the panel and the control software changes had to be made. In December 2012, it came to generator problems at two newly delivered machines. In January 2013, came to two machines to fire the newly developed lithium - ion batteries in the front and in the rear electrical room. Due to the second incident, the FAA issued an airworthiness directive that called for a proof for the safe operation of the batteries of the operators of the B787. In both cases the batteries were not overloaded. There have been frequent problems with the batteries, some had to be replaced due to deep discharge. This indicates a problem with the electrical control of the battery. Already in 2006 it came in laboratory tests to a fire in a lithium -ion battery. The battery type used by the Boeing 787 is the lithium cobalt oxide battery ( LiCoO2 ), which is very explosive. To retrieve the admission of the air supervisory FAA, Boeing has grabbed the battery in a steel housing, and also the individual battery cells isolated from each other. So should not spread to other cells and do not enter into the booth a possible fire.

Claim for compensation

Should negotiations by the end lead to an agreement, presented LOT Polish Airlines in August 2013 a claim for compensation in view. Dreamliner LOT had after the start of prohibition must be replaced by leased machines in spring, what had caused estimated costs of € 25 million.

Variants

The B787 was offered the program starts in three versions on the market: the two long-range variants 787-8 and 787-9 as well as the medium-range variant 787-3.

Boeing 787-3

The Boeing 787-3 was - like the Boeing 747- SR - designed for a special feature of the Japanese market, the plans, however, were discontinued due to low demand. In Japan, there are several domestic flights on partially only 400 km with a very high number of passengers for which the usual medium-haul aircraft such as the Boeing 737 are much too small. First, for this version were 43 orders received by Japanese airlines JAL and ANA, which they had probably used mainly on domestic Japanese routes - in the meantime, however, the orders of both airlines were canceled or converted to other series of 787.

Since takeoffs and landings aircraft significantly heavier burden than the cruise, the 787-3 would have received a significantly reinforced structure compared to -8, but would for a standard in regional traffic compared to the long-haul dense seating with about 290-330 seats significantly more passengers promoted as the version -8. The dimensions of the 787-3 would be the same as those of -8 been - apart from the slightly lower span as the blended winglets used on regional services not go as opposed to the more efficient for long- haul aircraft raked wingtips in width, but in height. Also had due to the smaller range fuel tanks reduced and thus the aircraft can be relieved.

In January 2010 it was announced that All Nippon Airways has converted its remaining 28787-3 orders in 787-8 orders. A role in the decision played the estimated availability of the model. This Boeing had no orders for the 787-3 more. In December 2010, this version was officially removed from the offer.

Boeing 787-8

The version -8 is the base model of the Boeing 787 She was commissioned as the first Boeing 787 version end of October 2011 with ANA in service and can carry about 210 to 250 passengers on long-haul routes. This version is with 494 firm orders to date (as of March 2014) the most popular. Are located at the wing tips at the 787-8 Raked wingtips. This model also performed the first flight, please refer to the program starting section.

Boeing 787-9

The version -9 is a stretched to about six meters compared to the 787-8 long-haul version of the Boeing 787 With this extension, the aircraft for 250 to 290 passengers, is designed, and also in the hull provide larger tanks at a relation to the 787-8 700 km extended range. Even with the 787-9 are raked wingtips on the wing tips. The first machine version -9 should be taken by the New Zealand Air New Zealand into operation in December 2010 originally. On 28 August 2009 it was announced that the first 787-9 to be delivered in the fourth quarter of 2013. On 27 October 2011 it was announced that the first 787-9 to be delivered until the first quarter of 2014. So far have been (as of March 2014) 405 aircraft on firm order. The first flight of this version was performed on September 17, 2013, November 7, came to the second plane. To this day, 787-9137 flight hours were conducted in the test program with the version.

Boeing 787-10

A 787-10 version, and Boeing 787 -10X was studied due to many customer requests for a larger 787 since the end of 2005 by Boeing. This should be (ie, opposite the 787-8 to twelve meters) stretched over the 787-9 again to about six feet. Thus, should find a place about 300 to 350 passengers, the 787, the largest version was previously designed slightly smaller than the Airbus A350, the direct competitor of the model A350 -900, A330 -300 and ( Boeing internal) of the Boeing 777- 200ER makes.

The development of this model was announced at the Paris Air Show in 2013 after a design different airlines had been presented. The hull is stretched to 5.5 meters ( 18 feet ) and is about 40 additional passengers compared to the Boeing 787-9 may take; Boeing's default configuration is 323 passengers in a 3-class seating. Since in this version merely hull length and capacity are increased, while the rest remains unchanged, the range of the Boeing 787-10 drops to 13,000 km ( 7,000 nm) with 300-330 passengers. The version -10 to also get raked wingtips.

So far, this model of the Boeing 787 was ordered by Singapore Airlines, which will receive the 30 copies from 2018/2019. The airline has chosen this order for engines of the model Trent 1000. The value of this order is estimated at 17 billion U.S. dollars. Another 20 orders were made by United Airlines, 30 ALC, 10 GECAS, 30 and 12 of Etihad Airways British Airways, making a total of 132 orders for this variant present (March 2014).

Contracts and options

On 4 April 2007 about a year before the then Scheduled to launch in the first instance, Boeing announced that it has reached the mark of 500 orders. This is the best presale result of a civilian aircraft today. By mid- 2008, with nearly 900 orders almost as many come together, as were built by the previous 767 series total.

Because of the delays, there was on the other side but also to numerous cancellations. So Azerbaijan Airlines announced on 7 April 2008, the contract for a georderte machine and instead ordered a Boeing 767 on the purchase of two additional 787 the airline think but firmly emphasized Boeing. On 29 January 2009 S7 Airlines announced to have canceled its entire order for the type. However, it stressed that instead was interested in leasing the type. A short time later, on 6 February 2009 it was announced that the leasing company LCAL has 16 of its originally ordered 21 787 Dreamliners canceled due to the difficult economic situation. Mid-June 2009 transformed Japan Airlines ( JAL) their order via 13787-3 in order 787-8; thus remained All Nippon Airways ( ANA) is the only customer for this variant. Also, ANA initially transformed two of its 787-3 orders into orders for the 787-8 and in January 2010 the remaining 28 also. Qantas announced on 25 June 2009 an order for 15 machines; was justified cancellation by the difficult economic environment of the airline.

The airline Air Berlin is the only German customer for the Boeing 787 it had originally been 25 copies ordered with an option for 25 more. Was made public on 16 March 2010 that ten firm orders canceled and the number of options have been reduced to five. In support of the company stated that they no longer need the originally ordered number 787 after the failed Condor takeover.

On September 25, 2011 first 787-8 was delivered with about three and a half years late to launch customer All Nippon Airways. The first long-haul flight took place at the newly established route Tokyo -Haneda -Frankfurt on 21 January 2012.

The Chilean airline LAN received her first 787-8 on 31 August 2012. Planned targets are Buenos Aires, Lima, Los Angeles, Madrid and Frankfurt. United Airlines 787 is used as a second American airline Boeing in December 2012 for long-haul flights. Only five days later, on September 6, 2012, Air India took over the first Dreamliner. On 15 November 2012, the first landed at a European airline delivered 787 on the Warsaw Chopin Airport, where it was placed in service for the LOT.

Mexico decided in August 2012 to a Boeing 787-9 to buy as a government plane. The machine is to be put into service in 2015; unnamed critics complain about the high purchase price in the face of poverty in the country.

Incidents

• November 10, 2010 had to make an emergency landing because of smoke in the cabin of one of the six test machines in Laredo, Texas. According to U.S. media, the cabinet had P100 of the machine caught fire, prompting several instruments failed and the pilots finally had to make an emergency landing on sight.
• On 31 July 2011, just weeks before the planned admission, ended a technical acceptance flight with an emergency landing. Shortly after the start of the company airfield in Everett on the U.S. West Coast, the pilot noticed problems with the flap control on the wings. About ten minutes after takeoff, the pilot declared an emergency and announced the return to the airport. There was, according to Boeing a "safe landing". According to the industry ministry Flightglobal The group is called a faulty sensor as the reason for the emergency landing. The incident forced the U.S. regulatory authority in any official inquiries.
• On January 7, 2013 exploded at a Dreamliner Japan Airlines on the Boston airport a battery. The broken fire was extinguished by the fire department. No one was injured, since there are no persons were on board the aircraft other than a mechanic. According to initial investigations the NTSB will not overcharge this battery has occurred.
• A day later, on January 8, 2013, had a Dreamliner Japan Airlines also the start because of a leak at the fuel tank cancel at Boston airport and could only stand a few hours later to Tokyo. According to the airport occurred in the incident from nearly 150 liters of fuel. All 178 passengers had left the machine without prejudice after the aborted launch.
• Another day later, on January 9, 2013, All Nippon Airways made ​​a Dreamliner on the ground, because a control computer was broken for the brakes.
• Two days later, on 11 January 2013 were two defects: cracks in the cockpit window and again oil loss. All five defects of the previous five days concerned the two Japanese airlines JAL and ANA.
• On January 16, 2013 had to make an emergency landing because of smoke in the cabin of a 787 of the airline ANA in Japan. The cause is a defect in the batteries was found. The two Japanese airlines ANA and Japan Airlines decided for now to let all 24 Boeing 787 on the ground and check. Shortly thereafter, the American U.S. Federal Aviation Administration issued a complete ban ( Grounding ) for all Dreamliner. Fast worldwide other authorities have connected this prohibition, including the EASA for Europe. This was the first time since 1979 that all airplanes of one type were held on the ground ( affected at that time were all McDonnell Douglas DC-10 because of problems with the engine mount ). On February 5, 2013 Boeing requested that the FAA conducting test flights, which could indicate progress in finding the problem. The approval for this was issued on February 8, 2013.
• On April 19, 2013, the FAA approved the new battery system for the Boeing 787 and has therefore made ​​the new current granting of permission to start in view. After retrofitting the machines may but for now take only up to 180 minutes long flights over sparsely populated areas or across the sea.
• On April 25, 2013, the FAA lifted the flight ban imposed in January, even if the investigation into the causes of battery overheating had not been completed. Aviation authorities in other countries also gave the green light.
