N411AK

The pilot was also the owner/builder of the amateur-built experimental airplane. He had removed and reinstalled the engine after the airplane experienced a propeller strike. The accident flight was the first flight after the engine was reinstalled. According to the pilot, he performed high-speed taxi runs, followed by a normal takeoff. After takeoff, the pilot climbed to altitude and confirmed the flight controls were functioning properly. He then entered the airport traffic pattern and on his first attempt to land, he performed a go-around. On his second attempt to land, the pilot reported that everything seemed normal, but he was fast on the approach and decided to add power for another go-around. The engine didn’t respond, so he proceeded straight ahead and secured the engine. The airplane landed past the departure end of the runway in a grassy area. The nose wheel dug into the ground and the airplane nosed over and came to rest inverted. Postaccident examination by Federal Aviation Administration Inspectors revealed substantial damage to the fuselage and the castle nut that attached the throttle arm to the fuel servo was missing a cotter pin.
