What happened
The pilot was on final approach following a Cessna 152 that was performing touch-and-go landings. The air traffic controller observed the Piper PA-23 overtaking the Cessna and instructed the pilot to execute a go-around. During the maneuver, the aircraft was observed to climb and then descend into the ground while in a left turn.
The pilot reported a possible loss of power on the left engine during the go-around procedure and noted that the landing gear and flaps had been raised.
The investigation
Investigators examined the aircraft's configuration and found the flap selector in the full down position. The gear selector was found in the down and neutral position. While the pilot reported a potential engine power loss, the investigation found no evidence of a mechanical problem with the left engine. However, testing of the fuel tanks revealed that both tanks contained automotive fuel.
