NTSB Narrative Summary Released at Completion of Accident
The airplane landed on the runway at the completion of a training flight. During the landing roll the nose gear collapsed. The airplane lost directional control, departed the left side of the runway, and collided with signs before coming to rest in the grass. Examination of the wreckage by an FAA Inspector revealed damage to the bungee assembly of the down lock link assembly, which did not allow the overcenter link to lock the gear down. In a written statement, the Inspector said,...'Bungee [assembly]...failed at rod end...not allowing overcenter link to lock gear down. This was due to possible hard landing prior to this flight bending bungee rod [assembly].'
NTSB Probable Cause Narrative
the collapse of the landing gear due to a bent gear locking mechanism for undetermined reasons.
