What happened
The pilot had previously encountered engine power loss when reapplying power after idling the engine following several landings. After consulting with a mechanic and determining that the fuel control system needed adjustment, the pilot departed for a maintenance facility.
During the flight to the mechanic's airstrip, the pilot performed a 360-degree spiraling descent to reduce altitude. Upon completing the maneuver and reapplying power, the engine experienced a surge followed by a total loss of power. The pilot subsequently executed a forced landing on soft terrain. During the landing roll, the left main gear began to dig into the ground, causing the gear to separate from the aircraft. The pilot was not injured.
The investigation
The investigation noted that the fuel control metering unit had undergone repairs in April 1991. This maintenance occurred prior to the aircraft being sold and relocated from New Mexico to Montana in November 1991.
