Test

The crew consisting of one test pilot, one radio navigator and two engineers departed Naples-Capodichino in the morning on a local test flight. En route, the twin engine airplane suffered a structural failure and the tail detached. Out of control, the aircraft entered a dive and crashed on the slope of a mountain located near Gragnano, about 27 km southeast of Naples. The aircraft was destroyed and all four occupants were killed.

The aircraft was on a functional check flight. According to the pilot and a witness (employed by the pilot), the left brake was locked during touchdown. Subsequently, the aircraft nosed over and a ground fire erupted which destroyed the plane. The pilot reported that the left brake had locked due to rust and corrosion and that the aircraft logbooks were destroyed in the fire. The pilot, sole on board, was uninjured.

The twin engine airplane departed Oberpfaffenhofen Airport at 1727LT on a local test flight with one pilot and two inspectors from the UK CAA. The flight was part of the UK Civil Aviation Authority's certification program for the type. En route, the airplane entered a nose-down attitude then dove into the ground and crashed in a wooded area. The aircraft was totally destroyed and all three occupants were killed. The loss of control occurred after the crew selected nose-down trim.

At 1201 EST, shortly after taking off from Runway 10L at Archerfield Airport, the airplane crashed into an annex attached to a Thiess Contractors workshop located in Kerry Road, Archerfield. The accident site was 455 metres east-north-east from the departure end of the runway. The pilot and four workmen taking their lunch break in the annex were killed. The aircraft and the annex were destroyed by impact forces and the following explosion and fire. The accident occurred during a test flight following corrective maintenance. The aircraft had completed a periodic inspection on 23 December 1981 but, during the next 10 days, a problem was experienced with the control of the left hand propeller. Following maintenance on 4 January to rectify the problem, the pilot elected to test fly the aircraft prior to its intended use for endorsement training at 1500 hours on the day of the accident.
