So we all remember the LOT 767 that had to make the belly landing in Warsaw on November 1st. Well the preliminary report is out and it looks like one of the circuit breakers that protects the alternate landing gear extension system was popped. Quote from AvHerald (

About 15-20 minutes after the end of the evacuation the first members of PKBWL arrived at the scene and found the "C829 BAT BUS DISTR" circuit breaker on the P6 panel was in the popped position, the "C4248 LANDING GEAR - ALTN EXT MOTOR" circuit breaker was in the closed position. The recordings of cockpit voice recorder and flight data recorder were secured.
Circuit breaker C829 protects a number of systems including the alternate landing gear extension system. It's position was not recorded or indicated by any aircraft system.
After the aircraft was lifted off the runway, the circuit breaker C829 was closed, then the alternate landing gear extension was activated and successfully extended the landing gear, so that the aircraft could be towed to the airline's maintenance hangar.

Ouch, that's a pretty expensive mistake that could have been avoided had the circuit breaker been checked. Anyone know if checking that panel would have been part of troubleshooting why the alternate gear extension system wasn't working?
