Investigation Summary
The flight was a short routine hop between Macau and Hong Kong, carrying 24 passengers and 3 crew members. Among the passengers were four men, led by Wong Yu, who intended to divert the aircraft to a remote location to rob the occupants. Minutes after takeoff, the hijackers drew pistols and ordered the pilot, Captain Dale Querubere, to surrender control. When Querubere resisted and attempted to fight off the attackers with a flare gun, he was shot in the head. The aircraft, left without effective pilot input during the melee, plunged into the sea near Kau Chau Island. The sole survivor, Wong Yu, was found by rescuers clinging to wreckage. He initially claimed to be a passenger who jumped before impact, but subsequent investigations by Hong Kong and Macau authorities, aided by the recovery of the aircraft and witness statements, identified him as the leader of the pirate gang.
Final Conclusions
The crash was caused by the loss of control following the fatal shooting of the pilot during a hijacking attempt. Although Wong Yu was identified as the perpetrator, he could not be prosecuted in Hong Kong because the crime occurred over Chinese territorial waters and the aircraft was registered in Macau, which was then a Portuguese colony. He was eventually released and deported to China, where his ultimate fate remains unconfirmed.
