On 6 February 2013, the Flight Instructor and a student conducted an instructional flight in the GA-7 Cougar aircraft, registration LV-AMH, practising runway circuits and four landings at Morón Aerodrome (AD) (SADM).
During the final landing on runway 01, the aircraft touched down about 200 m from the threshold, and after taxiing about 1500 m to exit the taxiway, the Instructor perceived that the aircraft was pitching forward due to partial nose wheel retraction.
The aircraft continued its trajectory for a few metres, brushing the propeller blades against the runway until it came to a stop and came to rest on the nose wheel.
the nose wheel. The instructor proceeded to cut both engines and both crew members left the aircraft under their own power.
The accident occurred in the afternoon, in daylight and in visual meteorological conditions (VMC).
Cause
During a training flight, during the landing phase, the nose gear of the aircraft partially retracted, with subsequent impact of both propellers against the runway surface, due to a combination of the following factors:
1) Breakage of the nose gear connecting rod overcentre lock stop.
2) Reduction of the strength area of the component, due to the presence of an advancing crack front (fatigue).
3) Probable abrupt impact of the aircraft during operation.
