Incident Overview
During cruise flight, the right engine of a single-engine aircraft caught fire and failed. The pilot responded by reducing altitude and executing an intentional wheels-up landing in a pasture. The aircraft slid on its belly before coming to rest.
Injuries and Damage
The pilot was uninjured in the accident. However, the aircraft sustained substantial damage and was deemed beyond repair.
Investigation Findings
The official investigation determined that the engine fire originated from improper maintenance. Contributing factors included inadequate maintenance and inspection practices. Specifically, the engine structure was compromised; valve assemblies were missing, and three valve cover screws were missing from both center cylinder on the right engine, with ten others loose. The investigation also noted the intentional wheels-up landing, the in-flight fire, and suspected or known aircraft damage as contributing elements.
