Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The pilot's failure to maintain lateral aircraft control that resulted in collision with terrain during landing.

Findings · 2

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings.

Analysis

The pilot was attempting to perform a soft-field landing, had full flaps selected, and was managing the descent with the throttle control. As the airplane transitioned to short final, it was configured in a nose-high stabilized approach with full flaps. The pilot added right rudder in attempt to gain visibility out the window straight ahead. With the airplane about 20 to 30 feet above ground level (agl) and 100 feet from the threshold, the pilot applied power to arrest the descent. The increase in power in combination with the rudder input resulted in the airplane's left wing contacting the ground. The pilot further added that there were no preimpact mechanical malfunctions or failures with the airframe or engine.

Factual narrative

In a written statement, the pilot reported that as the airplane was about 3 miles from the destination airport, he configured for landing by adding full flaps. He opted to perform a soft-field landing for the purpose of practice and began managing the descent with the throttle control. As the airplane transitioned to short final, it was configured in a nose-high stabilized approach. With the airplane 150 feet from the runway threshold, the pilot added right rudder in attempt to gain visibility out the window straight ahead. As the airplane was 20 to 30 feet above ground level (agl) and 100 feet from the threshold, the pilot applied power to arrest the descent. The increase in power, in combination with the rudder input, resulted in the airplane's left wing contacting the ground. In the section titled "RECOMMENDATION" in the NTSB Pilot/Operator Report, form 6120.1/2, the pilot stated that the application of rudder while adding full power created enough instability to drop the wing. The pilot further added that there were no preimpact mechanical malfunctions or failures with the airframe or engine.
