Jodel D11, VH-FTY, Caloundra, Queensland, on 2 September 1990

Circumstances:

The aircraft was observed to take off from Runway 15 and climb to about 500 feet before commencing a right turn. It then appeared to abruptly change attitude in pitch and roll a few times before adopting a nose low attitude and disappearing behind trees. The aircraft crashed into a shallow swamp and caught fire. On site examination revealed that the aircraft struck the ground in a steep nose and right wing low attitude. The pilot reported that the engine began running roughly and lost power shortly after take-off. An examination found no fault with the engine or carburettor, however, fire damage precluded testing of the magnetos. The aircraft attitude at impact was indicative of it being in a stalled condition.

Significant Factors:

The following factors were considered relevant to the development of the accident:

1. For reason(s) which could not be established, the engine apparently lost power.

2. The pilot lost control of the aircraft.
