De Havilland DH.104 Dove

The crew departed Bankstown on a local training flight. While circling near the airport, the Dove collided with a private Piper PA-30-160B Twin Comanche registered VH-WWB that was approaching Bankstown Airport on a flight from Sydney with also two people on board. Following the collision, both aircraft dove into the ground and crashed in a residential area located about 3 NM from the airfield. Both aircraft were destroyed and all four occupants were killed. Fortunately, there were no casualties on the ground. It is believed that the crew of the Dove encountered radio problems before the accident.

On approach to Vila Gago Coutinho, the crew failed to realize his altitude was too low when the airplane struck the ground. On impact, the undercarriage were torn off and the airplane slid on its belly for several meters before coming to rest. All occupants escaped uninjured while the aircraft was damaged beyond repair. The accident occurred somewhere in 1973 (the exact date remains unknown).

During the takeoff run, at V1 speed, the crew started the rotation when the left engine lost power. The captain elected to abandon the takeoff procedure but following a lack of coordination and poor experience, the crew lost control of the aircraft that veered off runway and came to rest. Both pilots were uninjured while the aircraft was written off.

While taxied by an unauthorized mechanic, the twin engine airplane went out of control and collided with a parked Fokker F27 Friendship registered PH-IOT and also operated by the Iraanse Aardolie Exploratie en Productie Mij (IAEPM). The mechanic was unhurt, the Dove was damaged beyond repair and the F27 was repaired.

After landing at Rock Sound Airport, the twin engine aircraft came to rest in flames. There were no injuries but the aircraft was destroyed by fire.

Few minutes after takeoff from Honolulu Airport, while flying along the coast, both engines failed simultaneously. The pilot reduced his altitude and ditched the aircraft few dozen yards offshore. While the aircraft sank and was lost, both occupants were rescued.

On approach to runway 31 at Mar del Plata Airport, the twin engine airplane crashed into the sea few km offshore. A pilot was killed while two other occupants were rescued.

Shortly after takeoff from Morris Airport, while in initial climb, the pilot informed ATC about an engine failure and was cleared to return for an emergency landing. On final, the airplane stalled and crashed in a field located short of runway threshold. The aircraft was destroyed and the pilot was seriously injured.

The crew was completing a positioning flight from Luton to Wolverhampton to carry two members of the Dowty Group (owner of the aircraft) who wanted to fly to France. A first attempt to land was abandoned due to poor weather conditions and the crew climbed to 2,500 feet before initiating a second attempt to land that was also abandoned. During the third attempt, the crew failed to realize his altitude was insufficient when the aircraft struck the roof of a house and crashed in flames 600 yards short of runway 25 threshold. The aircraft was destroyed as well as the house and both crew members were killed plus one people in the house. Two other person on the ground were injured.

The airplane departed Queenstown Airport at 1320LT for a local training flight. En route, while flying a lot height, the airplane struck a hillside located in the region of Lindis Pass. All three crew members were killed.
