What happened
The aircraft departed on a flight that ended in a forced landing shortly after takeoff due to a sudden loss of engine power. At an altitude of approximately 400 feet above ground level, the engine began to sputter before coming to a complete stop.
In response to the failure, the pilot attempted to restore power by switching the fuel tank selectors. This action resulted in a momentary increase in engine power, but the engine quit again almost immediately. Unable to maintain flight, the pilot guided the aircraft into a marshy clearing for an emergency landing.
The investigation
Post-accident analysis focused on the mechanical state of the aircraft and the actions taken by the pilot during the emergency. The pilot reported that he believed the accident was caused by possible fuel contamination. No other mechanical failures or structural damage contributing to the power loss were identified in the provided records.
Findings
The sequence of events indicates a sudden interruption in the engine's operation rather than a gradual decline in performance. The brief recovery of power after switching tanks suggests that the issue was related to the fuel supply system, potentially involving blocked or contaminated fuel lines or tanks. The pilot's assessment points toward fuel quality as the critical factor.
Safety message
Pilots should remain vigilant regarding fuel management and potential contamination risks. Regular inspection of fuel filters and samples is essential to prevent in-flight power loss due to impurities in the fuel supply.
