What happened
The pilot was conducting the final approach segment for runway 31 when the automated weather observing system (AWOS) indicated winds from 300 degrees at 15 knots, with gusts reaching 20 knots. During this phase of flight, the airplane experienced an unexpected loss of altitude. The aircraft subsequently impacted the runway surface with significant force.
Following the impact, the pilot attempted to execute a go-around or recovery maneuver by applying additional engine power. This action caused the airplane to begin porpoising on the runway surface. The vertical oscillation resulted in the collapse of the nose landing gear. As the nose lowered, the propeller struck the ground, and the aircraft veered off the paved surface onto the adjacent grass.
The investigation
The factual narrative indicates that the nose gear collapsed due to the forces generated during the hard landing and subsequent porpoising event. The propeller struck the ground as a direct consequence of the nose gear failure. No further mechanical examination details are provided in the source text regarding pre-impact airframe integrity.
Findings
Contributing factors included the wind gusts reported by the AWOS and the resulting hard landing. The pilot's application of power during the recovery attempt led to the porpoising motion that exacerbated the structural damage.
