Circumstances:
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.
Probable cause:
The cause of the accident was that following a reduction of power from the left engine, the pilot failed to maintain flying speed. The cause of the reduction of power was not determined. The accident may have been avoided if the pilot had employed the correct procedures following a reduction of power from the left hand engine.

Due to an improper level off, the twin engine airplane landed hard and came to rest. All four occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Hard landing caused by an improper level off on part of the pilot at controls and an inadequate supervision of flight on part of the pilot-in-command. This was a manufacturer's test flight with an FAA copilot at controls.

Circumstances:
The crew was engaged in a spraying mission in the region of Eldari and arrived on March 13. No flight was scheduled on March 14 so the crew decided to perform engine tests. The captain asked the copilot to give up his seat to the mechanic for the purpose of the engine test run. Three unauthorized passengers from a local farm embarked and the captain decided to takeoff despite poor weather conditions (visibility below minimums). The single engine aircraft took off at 1228LT with flaps down at 20°. During initial climb, at a height of about 25-30 meters, the airplane entered a right turn then lost height and crashed in a field located 600 meters from the point of departure. A passenger was killed while five other occupants were injured.
Probable cause:
It was determined that the captain decided to initiate a local test flight without a copilot in poor weather conditions (fog down to 50 meters and horizontal visibility down to 300 meters) without prior permission and with unauthorized passengers on board. In limited visibility, the airplane banked to the right to an angle of 30° and an excessive correction from the pilot-in-command caused the aircraft to be uncontrollable, to lose height and to crash.
