Aircraft flight hours:

Circumstances:
The crew was completing a cargo flight from Sydney to Brisbane. On short final in good weather conditions, the four engine aircraft crashed in unknown circumstances. The wreckage was found few hours later at Bulwer Island, about 1,5 km southeast of runway 01 threshold. The aircraft was destroyed by impact forces and a post crash fire and both pilots were killed.
Probable cause:
The accident occurred during the pre-landing circuit when the captain tried to leave his seat under the influence of a disordered cardiac function and, in the course of so doing, collapsed across the engine control console in such a way as to bring all four throttle levers to the closed position depriving the first officer of the throttle movement necessary to avoid a crash-landing off the airport.

Circumstances:
While cruising at an altitude of 12,000 feet, the crew informed ground about an in-flight fire and elected to divert to Bereina for an emergency landing. As the crew was unable to extinguish the fire, the airplane landed on fire and came to rest in flames. All three crew members were able to evacuate safely while the airplane burned for about 24 hours before being totally destroyed.
Probable cause:
It is believed the fire was caused incorrectly packed chemicals.

Circumstances:
On a flight from Jurien Bay to Perth, carrying a load of crayfish, the right engine failed. Unable to maintain a safe altitude, the pilot was forced to attempt an emergency landing 12 km north of Lancelin. All three occupants were uninjured while the aircraft and the cargo were lost.
Probable cause:
Following complete loss of starboard engine power, probably initiated by the failure of a piston, the pilot was unable to maintain height and in the subsequent forced landing, the aircraft collided with a limestone outcrop.

Circumstances:
The pilot Geoffrey Wallace was performing a cargo flight from Popondetta to Port Moresby and encountered poor weather conditions en route. At an altitude of 9,400 feet, the twin engine aircraft struck trees and crashed on Mt Owen Stanley. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the pilot was found. In October 1970, while searching for a missing Piper Aztec, the wreckage of the Piaggio was found.
Probable cause:
It was reported the pilot failed to follow the proper routing to Port Moresby.

Circumstances:
The aircraft was engaged in an aerial work operation, spreading superphosphate. On landing after the 35th sortie of the day the pilot reported to his loader driver that the elevator was sticking and tending to jam when the control column was pulled back to near the stop. The loader driver crawled into the rear interior of the fuselage, making a visual check of the elevator cables and pulleys as the pilot operated the elevator control. A small curl of 16-gauge metal, about 1/4 inch high, was found in the lower elevator pulley and removed. The pilot confirmed the operation of the elevator was now satisfactory and flying was resumed. At 10:15 the loader driver noticed that the noise of the aircraft had ceased and looking around saw the Fletcher lying wrecked on the summit of a ridge. The aircraft had dived into the ground at an attitude that was slightly over the vertical. All the wreckage, with the exception of the nose wheel, was confined to the immediate area of the point of impact. A witness mark on the dial of the ASI showed that the impact with the ground had occurred at a speed of 127 mph. There was no fire. The pilot Trevor Robert Wilson was killed.

Probable cause:
The integrity of the rudder and aileron systems was established. The upper elevator cable was intact but the lower cable was severed 12 inches from the eyebolt attachment to the counterbalance. The investigation found that a loose No. 6 PK screw had found its way into the lower elevator pulley groove when the plane was in a slight nose down attitude. When the pilot applied back pressure on the control column to raise the nose the screw had become jammed between the cable and the pulley guard pin. This had caused the elevator to lock, and the pilot's attempt to recover from the steepening dive had easily generated sufficient pressure for the sharp edge of the head of the screw to sever the cable.

Circumstances:
The aircraft was on the take off run when two cattle beasts suddenly appeared from sloping ground on the left of the strip and ran across. The pilot attempted to lift off to avoid a collision and the plane adopted a steep nose-high attitude, with the tail cone hitting the ground, before striking the animals. The impact caused the aircraft's elevators to separate from the airframe. The calculated ground speed at this stage was 71 mph and the aircraft overran the sloping end of the airstrip. It was thought that the pilot, unaware of the loss of the elevators, attempted to continue the take off in order to retrieve the situation, rather than trying to stop in the limited distance available on the sloping runway. The plane appears to have lofted, out of control, for a distance of 264 feet (80 meters) before striking the ground at angle of 70 degrees, and sliding another 66 feet (20 meters). The aircraft was wrecked and a fire broke out in the engine bay and was fed by the gradual discharge of fuel from the fractured outlets of the wing tanks. The loader driver and two others were quickly at the scene and the only fire extinguisher available, a 20-pound (9 kg) foam-type was used in an effort to blanket the pilot, whose leg was trapped, from the flames. Three other persons who had been working nearby arrived and assisted by bringing water from a pond close by. These commendable efforts were insufficient to quell the blaze and the pilot had suffered severe burns before he was finally removed from the wreckage. The pilot William George Jackson Deller died as the result of his injuries.
