What happened
The accident occurred during the landing sequence under conditions of strong gusting winds. The aircraft was equipped with floats, indicating it was configured for water operations or amphibious use. Shortly after the initial touchdown on the runway, a significant gust of wind impacted the aircraft.
Due to the aerodynamic forces generated by the gust, the pilot was unable to maintain directional control and keep the aircraft aligned with the runway centerline. The aircraft veered sharply to the left, leaving the paved surface and entering soft ground covered with sage brush. The force of the impact with the uneven terrain caused the aircraft to nose over and come to rest in an inverted position.
The investigation
The primary factors identified during the examination of the event were the environmental conditions and the aircraft's response to them. The presence of strong gusting winds was a critical element during the landing phase. The float-equipped configuration may have influenced the ground handling characteristics, particularly when transitioning from the runway to soft, uneven terrain.
Findings
Contributing factors included:
- Strong gusting winds present during the landing sequence
- Pilot's inability to maintain runway centerline after touchdown due to wind gusts
- Veering off the runway onto soft ground and sage brush
- Nosing over in an inverted attitude upon impact with the terrain
