What happened
During the initial climbout phase of flight, the pilot initiated a switch between the aircraft's fuel tanks. Shortly after this action, the engine ceased operation, resulting in a loss of power. The airplane subsequently descended and impacted a wooded area. Upon inspection, the aircraft was found to be substantially damaged. Despite the severity of the impact, the pilot sustained no injuries.
The investigation
A mechanical examination of the aircraft was conducted to determine the cause of the engine failure. Investigators discovered that a new fuel valve had been installed on the airplane just prior to the flight. Further analysis revealed that this component had been installed incorrectly, which likely disrupted the fuel flow when the pilot attempted to switch tanks.
Findings
The primary factor contributing to the accident was the improper installation of the fuel valve. This mechanical error prevented the engine from receiving adequate fuel during the tank switch, leading to engine failure and the subsequent crash. The incident highlights the critical importance of correct component installation procedures.
