Accident at Shearwater NS

Summary

2000-01-07: CFUOB PA30 on a local flight experienced Landing Gear Problems. Pilot tried to lower Gear through different methods until just about out of fuel. Pilot had to perform a Gear Up landing on runway 34. No agencies were informed of the problem until the aircraft had set down. 2 SOB no reported injuries. TSB case closed file # A00A0001 more info to follow. Update TSB File # A00A0001: The twin Comanche aircraft was on a local multi engine training flight with an instructor and commercially licensed student on board. When the pilot selected landing gear "down" in preparation for landing, after the training exercise was finished, the gear failed to extend. The pilot cycled the landing gear switch but the gear still would not extend. The pilot then attempted to extend the gear manually but when he tried to disengage the electric motor he found that the motor release arm was jammed. The pilot contacted company maintenance by radio and they suggested resetting the landing gear motor circuit breaker again (found to be tripped after initial gear extension attempt) and cycle the landing gear switch again. This was tried without success and maintenance then suggested trying to get some leverage on the motor release arm by tying a belt around the lever on the motor release arm. This was tried without success and it was then decided that the aircraft should circle the field burning off fuel before attempting a gear up landing. After about one hour of circling, an uneventful gear up landing was carried out with ERS in position. There were no injuries to either occupant. Airframe damage appeared minimal; however, both propellers were substantially damaged. The aircraft was in the hanger prior to the flight and the pre-flight inspection was carried out in the hanger. In order to get the aircraft out of the hanger, a privately owned aircraft, which was parked in front of the occurrence aircraft, had to be moved first. The owner of the private aircraft hooked the tug up to the tow bar on his aircraft and pulled it out of the hanger. He then proceeded to the accident aircraft, hooked the tow bar to the tug, and towed it out of the hanger, with the instructor and student walking the wings, onto the ramp. He then disconnected the tug from the tow bar and returned to his own aircraft. An examination of the aircraft after the occurrence revealed that the tow bar was still connected to the nose wheel and that it was wedged between the nose gear doors and the fuselage. This prevented the gear from fully retracting or extending. With the landing gear jammed in this position, the landing gear motor would continue to try and retract the landing gear until it overheated and tripped the circuit breaker. This would have also put a high pre-load on the mechanical components of the retraction mechanism and explains why the pilot was unable to move the motor release arm. End.
