Following a sudden loss of power shortly after takeoff, the pilot attempted to find a safe landing spot but ultimately crashed the aircraft into a large tree in a residential area due to water contamination in the fuel system.

What happened

Shortly after takeoff, the aircraft experienced a total loss of power at an altitude of approximately 300 feet above ground level. The pilot attempted to execute a forced landing in a nearby residential area. However, upon realizing that the terrain was too congested for a safe landing, the pilot intentionally guided the aircraft into a large tree.

The investigation

A post-accident examination of the aircraft revealed significant water contamination within the fuel tanks and the carburetor fuel line. This contamination was identified as the primary mechanical issue contributing to the engine failure.

Findings

The sequence of events indicates that water in the fuel system caused a total loss of power. The pilot's decision to land in a tree was a direct response to the inability to maintain flight and the lack of suitable landing zones in the surrounding residential area. No further mechanical anomalies were noted beyond the fuel contamination.

Safety message

This incident highlights the critical importance of pre-flight fuel sampling to detect water contamination, which can lead to sudden engine failure even shortly after takeoff.

Probable cause

The pilot's inability to maintain control due to a total loss of power caused by water in the fuel system.
