Aircraft experienced engine failure during cruise due to fuel exhaustion. The pilot attempted a forced landing but struck trees, resulting in significant damage and injuries.

What happened

The aircraft was operating in cruise flight when the pilot observed that the fuel gauges indicated a low fuel state. In response to this indication, the pilot turned toward an airport located closer than the intended destination. Shortly after initiating this maneuver, the engine quit. The pilot attempted a forced landing in a field; however, the aircraft contacted trees during the approach.

The investigation

Post-accident examination of the aircraft revealed that the fuel tanks were completely empty. Investigators noted distinct fuel stains trailing from the left fuel cap, the primer lines, and the area surrounding the carburetor. These findings confirmed a loss of fuel prior to the engine failure.

Findings

The primary factor leading to the accident was fuel exhaustion. The pilot's decision to continue flight despite low fuel indications resulted in the engine stopping. The subsequent attempt to land in an unprepared area led to contact with trees, causing substantial damage to the airframe. The presence of fuel stains around the left fuel cap and primer lines suggests a potential leak or improper sealing contributed to the depletion of fuel reserves.

Safety message

Pilots must monitor fuel quantities closely and plan for adequate reserves. If fuel gauges indicate low levels, immediate action should be taken to land at the nearest suitable airport rather than continuing toward a more distant destination.

Probable cause

The pilot's failure to ensure adequate fuel supply, which resulted in fuel exhaustion and engine power loss during cruise flight.
