Test

The crew was involved in a local test flight after the airplane has been rebuilt following another accident. After takeoff, the airplane went out of control and crashed by the runway. Both occupants were seriously injured and the aircraft was destroyed.

While the aircraft was being taxied into the hangar on 9 March 1969 for a Check III inspection the port elevator was damaged by contact with a set of passenger stairs. It was decided therefore to change the elevator during the inspection. The aircraft was test flown by the pilot-in-command after the inspection at 0600 hours on 18 March 1969. During the flight it was discovered that the elevator trim was ineffective. Subsequent examination revealed that the elevator trim tabs had been rigged in opposition, one up and one down. The aircraft was therefore returned to the hangar for rectification. A further test flight was scheduled at 0600 hours on the following day, i.e. 19 March. After completing the ground run and preflight check the aircraft was again returned to the hangar for further work on the elevator trim mechanism. One of the engineers reported that the elevator trim was "very stiff". The work was carried out by the pilot-in-command and an engineer, who were observed to carry out a functional check of trim operation after the work was completed. At 0730 hours the aircraft was lined up on the runway for take-off. The take-off and climb out were observed by two experienced witnesses and appeared to be quite normal. After a period of about two minutes and at an estimated height of 700 ft the aircraft made a turn to port through approximately 1600 at an estimated 300 bank angle. The aircraft was then seen to recover from the turn and immediately enter a dive which became progressively steeper until the aircraft struck the ground and burst into flames. All four crew members were killed.

The single engine aircraft was engaged in a local post maintenance test flight with one technician and one pilot on board. Shortly after takeoff, the airplane went out of control and crashed near the runway end, killing both occupants.

The pilot and his four passengers were engaged in a local post maintenance test flight. Following a local circuit, the pilot initiated an approach to Nederland-Jefferson County Airport when on final, the airplane stalled and crashed in a huge explosion. All five occupants were killed.

At liftoff, the twin engine aircraft stalled and crashed in flames by the runway. The aircraft was destroyed and the pilot, sole on board, was killed. He was engaged in a local test flight at Wichita-Beechcraft Field before the aircraft should be delivered to the French operator Flo Air.

Crashed in unknown circumstances somewhere in India while completing a test flight. Both pilots were killed.

The crew was completing a local test flight on this new aircraft which should be delivered to the Royal Australian Air Force. Upon landing, one of the main landing gear collapsed and the airplane came to rest in flames. While all four crew members escaped uninjured, the aircraft was destroyed by fire.

The crew departed Assis Airport for a local test flight. En route, the crew encountered an unexpected situation. The aircraft caught fire, went out of control and crashed onto a building. Both pilots were killed while there were no injuries on the ground.

The crew (four testers and five crew members) was engaged in a series of test flights on behalf of the Ministry of Aeronautical Industry (MAP – Ministerstvo Aviatsionnoi Promyshlennosti – Minaviaprom). While cruising at a relative low height at a speed of 400 km/h, the crew opened the cargo hatch when the lock of the fastening system fitting the rail jammed. The 'cargo' got stuck in the cargo hold and the four parachutes opened. This caused severe damages to the fuselage and the separation of the tail. Out of control, the airplane plunged into the earth and crashed in a huge explosion at the edge of a wooded area located one km north of the village. All nine occupants were killed.

The crew was involved in a local test flight out from Southend Airport in the goal to renew the Airworthiness certificate. Shortly after takeoff, while in initial climb, a technical failure occurred on the engine number four. The crew was forced to shut down the engine and to feather its propeller when control was lost. The airplane lost height and crashed in an open field located near the airport, broke in two and came to rest. While all three crew members were injured, two people on the ground were killed.
