During a precautionary landing, an aircraft floated down a grass runway, was lifted by a gust after first touchdown, then overran the end and went over a 20-foot drop-off, collapsing the nose and one main gear.

Precautionary Landing and Float

The aircraft was making a precautionary landing at a remote grass airstrip. It did not touch down until after it had floated at least one-quarter of the way down the 5,000-foot-long grass runway.

Gust of Wind and Second Touchdown

After the initial touchdown, and before the pilot applied brakes, a gust of wind lifted the aircraft back into the air. The aircraft then touched down a second time.

Runway Overrun and Terrain

Following the second touchdown, the pilot applied maximum braking. However, the aircraft could not be stopped before it departed the end of the runway and went over a 20-foot drop-off. At the bottom of the drop-off, the aircraft encountered rough and uneven terrain.

Outcome

The encounter with the rough terrain resulted in a collapse of the nose gear and one main gear leg. The aircraft sustained damage from the gear collapse.
