RAAF aircraft ever to have been hijacked. Detachment A was no longer required after Papua New Guinea achieved independence from Australia and established its own defence force, and the unit was disbanded on 17 January 1976. Three Caribous were lost while operating with the detachment; A4-202 crashed near Porgera on 3 June 1965, A4-147 was written off after it landed short of the runway at Tapini Airport on 6 October 1968 and A4-233 was destroyed when it crashed at Kudjeru Gap on 28 August 1972. The last of these crashes caused the deaths of 25 aircrew and passengers, making it the RAAF's worst peacetime disaster; 21 of the people killed were high school students returning from an army cadet camp. Following the end of its permanent presence at Port Moresby, No. 38 Squadron continued to fly periodic training sorties in Papua New Guinea. During the 1980s, detachments of No. 38 Squadron were established at RAAF Base Darwin and RAAF Base Pearce near Perth to provide these regions with a search-and-rescue capability and to exercise with Army units. The Pearce detachment was nicknamed "Blackduck Airlines". No. 38 Squadron moved from Richmond to RAAF Base Amberley, west of Brisbane, in October 1992. At this time the squadron continued to be responsible for all Caribou conversion training, as well as conducting tactical transport operations. The permanent detachment of No. 38 Squadron aircraft to RAAF Base Pearce ceased in 1999, and Detachment B of the squadron was established at RAAF Base Townsville in North Queensland during 2000. From 1999 until early 2001, elements of No. 38 Squadron, designated No. 86 Wing Detachment C, were stationed in East Timor and supported the international peacekeeping force which had been deployed there to end the violence that had broken out following a successful referendum on independence conducted in August 1999. At its peak strength, four Caribous were assigned to the detachment. The air and ground crew deployed to East Timor endured difficult living conditions until their accommodation and recreation facilities were upgraded in mid-2000, and the pilots were regularly required to fly into poorly maintained air strips. Despite the age of the Caribous and shortages of spare parts, Detachment C's ground crew managed to maintain a high aircraft serviceability rate. In 2000 No. 35 Squadron was deactivated, leaving No. 38 Squadron the RAAF's sole Caribou operator. By September 2002, No. 38 Squadron was equipped with 14 Caribous.
