History of the Flight
On 14 July 2020, the crew of a Tecnam P2006T, registration SP-KEY, operated by ATO GRAFPROM AVIATION, planned to conduct MEP(L) training. The crew consisted of a flight instructor (ATPL(A), aged 61) and a student-pilot (PPL(A), aged 27). The training included exercise number 3: flight in a flight zone with asymmetric thrust and practice of emergency procedures with one engine inoperative.
Takeoff occurred at 09:30 LMT from Bydgoszcz Aerodrome (EPBY). Around 10:00 LMT, the crew reported completing the task in the flight zone and began their return. On the downwind leg, the student reported the aircraft position and intention to land on runway 08. While on final approach, the crew received clearance to land on runway 08. However, the instructor changed his intention and requested clearance for a touch-and-go or a low pass. The tower controller cleared the crew for a low pass, which was executed over runway 08 with the landing gear extended and flaps set to 20°.
According to the tower controller, the aircraft flew over the runway at a high angle of attack, at low speed, and at a height of several meters. After passing the end of runway 08, the aircraft began a right turn with a slight climb. A few seconds later, the aircraft stalled and, in the initial phase of the low-altitude stall, rolled to the right and crashed into the ground. The collision occurred at 10:08 LMT, as recorded by the aerodrome CCTV camera.
Injuries and Damage
The accident resulted in fatal injuries to both crew members. The aircraft was destroyed by the impact and subsequent fire, which broke out approximately 30 seconds after the crash. The fire also damaged approximately 80 m² of the aerodrome's grass surface due to unsealed fuel tanks and rescue operations.
Cause and Contributing Factors
The investigation determined the cause of the accident as an airplane stall during a go-around procedure. Contributing factors included performing the go-around with one engine inoperative and its propeller windmilling, performing the go-around with landing gear extended and flaps set to 20°, and the instructor's limited experience in conducting MEP(L) training (68:56 flight hours on type, of which 13:19 as flight instructor on multi-engine aircraft). No safety recommendations were proposed by the PKBWL.
