What happened
According to the pilot's account, the aircraft experienced a bouncy landing sequence that ultimately resulted in significant structural damage. During the initial approach, the airplane bounced back into the air after the first touchdown. The pilot attempted to correct the descent, but the same bouncing motion occurred on the second touchdown.
Following the second contact with the runway, a gust of wind lifted the aircraft off the ground again. This unexpected lift caused the airplane to settle onto its nose gear rather than the main landing gear. On the third and final touchdown, the nose gear failed under the stress, causing the aircraft to nosed over completely.
The investigation
The available source material does not provide specific details regarding mechanical inspections or post-accident examination of the airframe components beyond the pilot's narrative of the event sequence.
