What happened
On 24 November 2020, a student pilot was conducting her first solo enroute flight in a Cessna C-150, registration SP-KHD, operated by the Dęblin Aviation Training Centre. The flight began at the EPDE aerodrome with the intention of navigating a planned route. During the flight, the pilot observed lowering cloud bases and decided to descend from 1,500 ft to approximately 1,100 ft to maintain visual flight rules.
While flying at this lower altitude, the pilot noticed a change in engine sound and a significant drop in RPM, falling from 2300 to 1950 RPM. Despite attempts to increase power via the throttle, the engine performance continued to degrade. The pilot reported the engine problem to air traffic services and prepared for an off-field emergency landing near Brzóza. During the final approach, the pilot attempted to maneuver the aircraft to avoid a large stone in the landing area. This sudden maneuver at low speed caused the aircraft to stall, resulting in an uncontrolled touchdown and a subsequent turnover of the aircraft. The pilot sustained minor injuries and was able to exit the wreckage unassisted.
The investigation
The PKBWL investigation examined the aircraft's maintenance records, meteorological conditions, and the pilot's training history. Investigators found that the aircraft was airworthy and properly maintained. The investigation focused on the sequence of events leading to the engine power loss and the circumstances of the landing maneuver. The team also reviewed the student's recent training, noting she had recently resumed flying after a hiatus in training.
