What happened
Prior to the flight, the pilot and a passenger were observed consuming alcoholic beverages while traveling to the airport. Upon arrival, taxiing to the runway proved difficult for the crew. The flight was eventually cleared for takeoff only after the aircraft had entered the active runway without receiving proper clearance.
After departing, witnesses noted that the aircraft was leaving the ground with its landing gear still extended. Shortly thereafter, observers saw the plane flying erratically near a lake, with the right engine sputtering. The aircraft then dipped toward the water and executed a right turn. During this maneuver, the right wing struck the surface of the lake, causing the aircraft to cartwheel and crash.
The investigation
A mechanical examination of the right engine revealed that the fuel injector line connected to the number six cylinder had failed beneath a rubber grommet due to fatigue. Investigators also found that the fuel selectors were positioned such that both engines drew fuel from the left outboard tank, a configuration not recommended for takeoff operations. Additionally, the right propeller was found in an unfeathered position.
Findings
Toxicology reports indicated significant impairment at the time of the accident. The pilot had a blood alcohol level of 289 mg/dL (0.289%), while the passenger tested positive for 146 mg/dL (0.146%) alcohol. The combination of engine failure and pilot impairment led to the fatal outcome.
Safety message
Operating an aircraft under the influence of alcohol is strictly prohibited and extremely dangerous. Proper pre-flight planning, including fuel configuration checks, is essential for safe operations.
