## Probable cause

The pilot failed to maintain control of the airplane while maneuvering to land resulting in contact with a power line and the ground. Contributing to the accident was the pilot's lack of familiarity with the airplane.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Analysis

The pilot was relocating his airplane to a private airstrip. On arriving at the airstrip, the pilot did two takeoffs and landings without incident. During the takeoff and climb for a third approach and landing, the pilot experienced and uncontrolled roll to the left. The pilot put in right aileron but the input did not seem to have any effect on the roll. The roll turned the airplane toward a power line located east of the runway. The pilot could not recall if he applied engine power or tried to climb to keep the airplane from contacting the power line. The airplane struck the power line and subsequently impacted the ground seriously injuring the pilot and resulting in substantial damage to the fuselage and left wing. The airplane was equipped with flaperons. The pilot said he was not using flaps, and that the airplane's thick wing reduced the effect of power during the descent. The pilot reported having one hour total time in the accident airplane make and model.
