What happened
On October 31, 2014, a pilot operating a Cessna 152 initiated a navigational training flight departing from Białystok Krywlany Airport (EPBK) with the destination of Sobienie Szlacheckie (EPSJ). During the mission, the pilot performed two separate landings at Grądy airfield (EPGY) to refuel the aircraft.
The flight concluded with a landing back at EPBK at 16:48 local time. This arrival occurred approximately 50 minutes after sunset, which had taken place at 15:58 local time. At the time of the landing, the runway at the aerodrome was not illuminated.
The investigation
The investigation was conducted by the Aeroklub Białostocki. The PKBWL noted that despite two formal requests for the incident investigation results sent in July and October 2015, the final report from the investigating body was not provided to the Commission by the conclusion of the inquiry. Consequently, the PKBWL determined the probable cause based on the initial information provided in the aviation occurrence report.
