On November 1 , 2011 , LOT Polish Airlines Flight 16 , a 767-300ER , safely landed at Warsaw Chopin Airport in Warsaw , Poland after a mechanical failure of the landing gear forced an emergency landing with the landing gear up . There were no injuries , but the aircraft involved was damaged and subsequently written off . At the time of the incident , aviation analysts speculated that it may have been the first instance of a complete landing gear failure in the 767 's service history . Subsequent investigation determined that while a damaged hose had disabled the aircraft 's primary landing gear extension system , an otherwise functional backup system was inoperative due to an accidentally deactivated circuit breaker
