What happened
The incident occurred following an agricultural application run. The pilot reported detecting the distinct odor of burned oil while operating the aircraft. Shortly thereafter, visible smoke was observed emanating from the engine compartment. This visual cue coincided with a significant mechanical event: the engine began to miss heavily under load.
Investigation of the mechanical failure revealed that the number five cylinder had failed completely. The loss of power and subsequent erratic engine operation left the pilot with limited options for continued flight. Recognizing the severity of the situation, the pilot initiated an emergency procedure.
The pilot selected a nearby flooded rice field as the most viable landing site given the terrain and water depth. Upon touchdown, the aircraft's landing gear could not support the weight or impact forces. The gear collapsed immediately upon contact with the ground. The momentum of the crash caused the airframe to roll over onto its back.
The investigation
Examination of the engine confirmed that the number five cylinder had failed. This mechanical failure was identified as the primary reason for the loss of power and the subsequent hard miss observed by the pilot.
Findings
The sequence of events leading to the accident was determined to be:
- Failure of the number five cylinder during operation
- Loss of engine power resulting in a forced landing
- Collapse of the landing gear upon impact with the ground
- The aircraft flipping over due to the force of the crash
