Event Description
An aircraft experienced a loss of engine power after the pilot reported rough engine operation. The application of carburetor heat did not restore power. During the landing approach, the engine ran rougher and was only able to produce about half of its normal power.
Sequence of Events
While on the downwind leg of the traffic pattern, full power was regained. The pilot elected to perform a go-around because the aircraft's altitude was too high for a landing. However, while approaching the turn to the base leg, a total loss of engine power occurred.
The aircraft was then force-landed on a dirt airstrip, touching down in the midfield area. Unable to stop before the end of the strip, the aircraft continued past the runway edge. The nose gear collapsed, and the aircraft nosed over.
