Problems with the computer and the APUs
A few hours before re-entry in aligning the shuttle crashed, while the RCS thrusters were fired, one of the navigation computer. A few minutes later crashed another computer, but was able to reboot successfully. Young delayed the landing and let the shuttle initially drift free. He later explained: "If we had at this time the Backup Flight Software enabled, the result would have been a total loss of the orbiter and the crew. " An investigation after the flight showed that the GPCs failed, as by the RCS thrusters pulse a solder joint broke and so caused a short circuit on the CPU board. Columbia landed, after 166 orbits and 4.3 million kilometers covered, on December 8 1983 at 15:47 clock PST on runway 17 at Edwards Air Force Base. Shortly before landing caught two APUs ( of three) fire when ignited by a hydrazine leak released fuel on a hot surface. The landing was still successful. Columbia was transported back to the Kennedy Space Center on December 15. The leak was discovered after the fire, which had caused considerable damage to this part of the orbiter, was extinguished by itself.
