Probable cause
the pilot intentionally operated the airplane with known damage on the left wing which resulted in the pilot's inability to maintain control of the airplane during takeoff.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot made a forced landing on a road following a loss of engine power. The leading edge of the left wing and left aileron were damaged when it contacted a road sign during the landing. The pilot was able to get the engine started. He decided to takeoff on the road and fly back to his private airstrip. The pilot reported that once airborne, the airplane began to roll to the left. He reported that he added right aileron control, but the airplane continued to roll until it contacted the terrain.

The flight was originating at the time of the accident.
The pilot reported that he made an emergency landing on the road following a loss of engine power. He stated that during the forced landing, the left wing of the airplane contacted a road sign. This resulted in damage to the leading edge of the wing and left aileron. The pilot reported that he had mechanics look at the airplane and it was determined that the loss of power was due to an "air lock." He stated they bled the fuel line and started the engine. The pilot reported that he determined that he could fly the airplane off the road and back to his private airstrip. The pilot stated that once airborne the airplane rolled to the left. He stated that he added right aileron control, however the airplane continued to roll until it struck the ground.
