What happened
The pilot reported that during the initial phase of the takeoff roll, an attempt to rotate the aircraft at 50 knots was unsuccessful. Consequently, the decision was made to abort the takeoff at 70 knots by reducing engine power. At the moment power was reduced, the aircraft exhibited an unusual behavior, suddenly jumping into the air while maintaining a steep nose-up attitude of approximately 45 degrees.
In response to this sudden pitch-up, the pilot pushed the control yoke forward to lower the nose. This action resulted in the aircraft impacting the runway surface with its nose gear striking first. There were no reports of injuries or fatalities associated with this incident, and the event occurred during the takeoff phase of flight.
The investigation
Following the incident, investigators conducted a thorough examination of the aircraft to determine the mechanical status of the systems involved in the flight controls. The inspection focused specifically on the integrity and functionality of the components responsible for pitch control and elevator movement.
The technical review revealed that there were no mechanical malfunctions or failures detected within the flight control system. This finding suggests that the unexpected pitch-up behavior was not caused by a failure of the control surfaces, cables, or linkages.
