Accident & incident history
The airplane owner/builder’s inappropriate use of a lower grade fuel than that required by the airplane and engine operations manual, which resulted in engine detonation and the degradation and eventual obliteration of the Nos. 1 and 2 cylinder spark plug electrode tips. Contributing to the outcome was the pilots’ decision to continue flight at low altitude following a partial loss of engine power instead of performing an immediate precautionary landing, which resulted in collision with an overpass and terrain.
