B763, Warsaw Poland, 2011

Summary

On 1 November 2011, a Boeing 767-300 landed at Warsaw with its landing gear retracted after declaring an emergency in anticipation of the possible consequences which in this event included an engine fire and a full but successful emergency evacuation. The Investigation attributed inability to achieve successful gear extension using either alternate system or free fall to crew failure to notice that the Battery Busbar CB which controlled power to the uplock release mechanism was tripped. Gear extension using the normal system had been precluded in advance by a partial hydraulic system failure soon after takeoff from New York.

Description

On 1 November 2011, the crew of a Boeing 767-300 (SP-LPC) being operated by LOT Polish Airlines on an international passenger flight from Newark to Warsaw as LOT 16 were unable to extend the landing gear using either the alternate or free fall systems after the normal system had been disabled soon after takeoff due to a partial hydraulic system failure. After an ‘emergency’ had been declared, a daylight VMC approach was followed by a belly landing which resulted in the right engine catching fire. The aircraft was stopped on the runway and the engine fire was quickly controlled and a successful evacuation of all 231 occupants accomplished.
