The pilot stated that on Monday 21 August 1995, he was the captain of VH-JOC rostered to fly from Cairns to Weam via Daru. The aircraft departed Daru for Weam as per flight plan and arrived overhead Weam at 1215 pm local time. The pilot said he observed a Piper PA-31 Navajo and a BN-2 Islander aircraft parked in the parking area. The pilot of the Islander had previously provided the pilot of VH-JOC with a strip report and had advised that the strip was serviceable. The pilot stated that a normal circuit entry, approach and landing were conducted. The aircraft touched down normally and at approximately 60 kts braking was applied. The right maingear then appeared to lock up or strike something. Braking was released but the aircraft yawed to the right. The pilot said he tried to correct the yaw with rudder but it became worse. The nosewheel appeared to dig into the runway surface and he was unable to hold the weight off the nosewheel due to the yawing effect. The gear then collapsed, and the aircraft slewed further right before coming to rest. Subsequent examination of the right maingear by an engineer revealed that the pivot bolt had pulled through the torque links after the retaining washer had been sheared. This failure then allowed the wheel to castor outwards, and resulted in loss of directional control and collapse of the left main and nose gear. Two pilots who witnessed the accident said that there was a strong crosswind from the left, backing to a tailwind component on the landing. They said the aircraft was going sideways and looked as if it was going to ground loop prior to the failure of the torque link.
