What happened
On February 21, 2002, a Swiss-registered Beechcraft BE F35 departed Egelsbach for a flight to Grenchen under visual flight rules. During the flight, the pilot decided to abort the original mission and return to Egelsbach due to deteriorating visibility. However, the pilot subsequently diverted to Mannheim City airport.
While on final approach to runway 27, the pilot initiated a go-around at an altitude of approximately 3 meters. During the transition into the climbing turn, the engine failed. This loss of power caused the aircraft to enter an accelerated stall, leading to a nose-down pitch. The aircraft struck an allotment garden area vertically. Although the pilot survived the initial impact and was briefly conscious, he succumbed to his injuries at the scene.
The investigation
The investigation examined the aircraft's configuration, the pilot's experience, and the mechanical state of the engine. Investigators found that the aircraft's fuel tank selector was set to an auxiliary tank. According to the aircraft's operating manual, these tanks are intended for use during cruise flight only. The investigation also noted that while the pilot held a valid private pilot license, his experience specifically with the Beechcraft BE F35 was very limited, totaling only 4 hours and 10 minutes of flight time.
Findings
- The primary cause of the engine failure was an interruption of fuel flow caused by the pilot selecting the incorrect fuel tank setting for landing.
- The pilot's decision to execute a go-around during a 10-knot crosswind contributed to the loss of control once the engine failed.
- The aircraft's flight weight and center of gravity were within limits, and no mechanical defects were found in the engine or airframe.
- The pilot was not wearing his seatbelt at the time of the impact.
