What happened
The incident occurred during a training flight involving a student pilot under supervision. According to the flight instructor, this event marked the student's third supervised solo flight. The initial phase of the operation proceeded without issue, as the first two landings were completed normally.
However, complications arose during the approach for the third landing. As the aircraft entered the flare phase in preparation for touchdown, it began to porpoise. This unstable oscillation caused the airplane to collide with the ground surface. Following the impact, the aircraft veered off the right side of the runway and subsequently nosed over.
The investigation
The flight instructor provided a direct account of the events leading up to the accident. The narrative focuses on the specific phase of flight where the instability manifested. No mechanical failures or external factors were cited in the immediate description of the event.
