Maersk Air Fokker F27 Training Accident at Rønne Airport (OY-APB)

Rønne (Bornholm Island), DenmarkTakeoff (climb)

On December 27, 1969, a Fokker F27 Friendship (registration OY-APB) operated by Maersk Air was involved in an aviation accident near Rønne (Bornholm Island), Denmark during takeoff. No fatalities were reported. Investigators recorded the probable cause as: During takeoff followed by a simulated engine failure, the aircraft was in a situation with limited climb ability. The trainee attempted a climb rate that caused the airspeed to fall below the desired level, leading to a stall or near-stall condition. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 1 related events involving the same aircraft type or operator are linked below.

A Maersk Air Fokker F27 crashed into the sea near Rønne Airport during a training flight. The accident occurred after a simulated engine failure during takeoff, leading to a stall and loss of control.

Incident Overview and Flight Details On a training flight, a Maersk Air Fokker F27 departed Copenhagen Airport at 15:00 hours, climbing to flight level 70 before heading to Rønne Airport on the island of Bornholm. The flight included an instructor captain from Fokker Aircraft and three trainee pilots. Upon arrival at Rønne, the aircraft completed two normal touch-and-go landings on runway 29 using the instrument landing system. ## Simulated Engine Failure and Takeoff The third approach was planned with a simulated failure of the right engine. After the second touch-and-go, the aircraft was cleared to 2,000 feet. The instructor briefed the trainee on the single-engine approach, noting that an immediate takeoff using both engines would follow, with another simulated engine failure planned between V1 and V2. As the aircraft passed the NDB, the instructor reduced the right engine's torque to approximately 50 psi, simulating zero thrust. The trainee executed a normal landing. ## Loss of Control and Crash After touchdown, the instructor selected 16.5 degrees of flaps, re-trimmed the aircraft, and requested a takeoff at 85 knots. The trainee applied power to both engines, released the throttles at V1, and pulled the aircraft into the air, ordering the gear up. As the gear retracted, the instructor cut the left engine. The trainee established a 9-degree climb on the flight director but pulled back on the control column to hold V2 until 400 feet. The speed dropped to 88-89 knots, and the aircraft began rolling left. The trainee counteracted with ailerons, but the aircraft rolled right, and the trainee reported being unable to control the aircraft. The instructor took over the controls and applied full power to the left engine, but the aircraft continued to sink. It struck bushes and the ground approximately 270 meters west of the runway end, on a slope descending to the sea. The instructor pulled both throttles back, and the aircraft crashed onto a stony beach at the water's edge. The aircraft broke into several sections and came to rest in 1.5 to 2 meters of water, about 90 meters from the initial point of contact.

Probable cause

During takeoff followed by a simulated engine failure, the aircraft was in a situation with limited climb ability. The trainee attempted a climb rate that caused the airspeed to fall below the desired level, leading to a stall or near-stall condition. The instructor failed to identify the dangerous situation quickly enough and initiate the necessary corrective actions.
