THE AIRPLANE LANDED WITH THE LANDING GEAR RETRACTED. THE AIRPLANE HAD RECENTLY UNDERGONE REPLACEMENT ON THE LANDING GEAR TRANSMISSION AND MAINTENANCE ON THE GEAR SYSTEM. AFTER THE AIRPLANE WAS RAISED FROM THE RUNWAY, THE LANDING GEAR WAS EXTENDED MANUALLY. POST ACCIDENT INVESTIGATION REVEALED THE GEAR MOTOR CIRCUIT BREAKER WAS POPPED.
