Shortly after the evacuation, a team from the Polish State Commission for Aircraft Accident Investigation arrived, and discovered that the C829 circuit breaker, which protects a number of systems including the alternate landing gear extension system was "popped". The C4248 breaker for the alternate landing gear remained closed.
After the plane was lifted off the runway, the C829 circuit breaker was closed, and the landing gear was extended, using the alternate system. The plane was then towed to the LOT maintenance hangar, [13] for repairs and further investigation.[14][15]
По поводу предохранителей.
Варшава, LOT 16. Аварийная посадка, эвакуация, аэропорт закрыт на несколько часов, самолёт в ремонт. А дело то было как раз в предохранителе.
