What happened
The pilot initiated a takeoff roll oriented toward the north. During the acceleration phase, the airplane encountered a sudden gust of wind. This aerodynamic disturbance caused the aircraft to pitch upward excessively, resulting in the nose gear collapsing and the airplane resting on its nose.
The physical inspection confirmed significant damage to the propeller, the spinner assembly, and the lower engine cowling. No other structural failures were noted beyond these components.
The investigation
A thorough mechanical examination of the aircraft was conducted following the incident. Investigators checked for any pre-existing issues with the flight control systems or other critical aircraft systems. The inspection revealed no anomalies in the flight controls or operational systems that would have contributed to the event.
Findings
Meteorological data for the vicinity at the time of the incident indicated winds from 250 degrees at 9 knots, with gusts reaching 17 knots. These conditions were sufficient to affect the aircraft's stability during the critical takeoff phase. The primary factor was the interaction between the aircraft and the wind gust.
Safety message
Pilots should remain vigilant for sudden wind shifts or gusts during takeoff rolls, particularly in light aircraft where control authority may be limited at low speeds.
