Double Six crash
On 6 June 1976 a light aircraft crashed on approach to Kota Kinabalu, killing Sabah's chief minister and four other members of the new state government, and this page sets out what the records establish about the crash, what followed it in state and federal politics, and which questions are still argued over fifty years later.
what happened
On the afternoon of 6 June 1976 a Sabah Air Nomad aircraft flying from Labuan came down in shallow water off Kampung Sembulan, about two kilometres short of Kota Kinabalu airport. All 11 people on board died. Among them were Chief Minister Tun Fuad Stephens, four other members of the state government, two senior state officials, the secretary to the federal finance minister, the chief minister's bodyguard, the chief minister's son and the pilot. The date gave the event its name in Sabah: Double Six.
The political weight of the loss came from its timing. Fuad Stephens had been Sabah's first chief minister at the formation of Malaysia in 1963 and had proposed the name Sabah itself. He had returned to office only weeks earlier, sworn in on 14 April 1976 after Berjaya won that April's state election and displaced the USNO government. He died 53 days later. His deputy, Harris Salleh, became chief minister and held the post until April 1985. Eight days after the crash, on 14 June 1976, the state signed the petroleum agreement providing a 5 per cent cash payment under the Petroleum Development Act framework, an arrangement that has been argued about in Sabah politics ever since.
For 46 years the official investigation stayed classified. Harris Salleh, who had spent those decades answering insinuations about his own role, went to court in 2022 to have it released; the Kota Kinabalu High Court ordered declassification, the federal cabinet approved it on 5 April 2023, and Transport Minister Anthony Loke made the report public on 12 April 2023. The report, completed in January 1977, found no evidence of sabotage, fire or explosion, and gave the probable cause as a centre of gravity well outside the aft limit that left the pilot unable to control the aircraft on approach. It also recorded that the pilot had flown twice earlier that day and had exceeded his standard duty period. Australia, whose government factory built the Nomad, released its own records shortly afterwards.
Release did not settle everything. Datuk Donald Mojuntin, whose father died in the crash, has asked why the flying controls failed if the airframe was intact, and why the file was withheld so long; families raised the possibility of legal action and then set it aside on grounds of cost. The question of whether the 5 per cent agreement would have looked different had Fuad Stephens lived remains a live argument, with Conrad Mojuntin saying he would never have accepted that figure and Harris Salleh saying he supported the parliamentary arrangement and that the terms were a federal matter in any case. Joseph Pairin Kitingan has accused Harris Salleh of acting alone; Harris rejects that.
Fifty years on, on 6 June 2026, families and state officials laid wreaths at the Sembulan memorial. Speaking there, Donald Mojuntin framed the day as a reason for Sabahans to unite and to defend the state's rights. For a first-time voter, the useful point is that Double Six sits at the junction of two things that still shape Sabah politics: the abrupt loss of a generation of state leaders, and the petroleum settlement signed in the days that followed.

The parts nobody agrees on
alleged
Allegations of deliberate interference in the crash. The declassified Malaysian report concludes there was no evidence of sabotage, fire or explosion; suspicion of foul play nonetheless circulated for decades, and Harris Salleh said in April 2023 that he hoped declassification would end 46 years of what he called slander directed at him.

contested
Whether the investigation adequately examined mechanical failure. Datuk Donald Mojuntin, son of the late minister Peter Mojuntin, has said the reports described the airframe as intact while the flying controls failed, and asked whether that was properly investigated and why the report stayed secret for more than 40 years.
uncertain
Whether overloading with duty-free cargo caused the aft centre of gravity. Accounts reported by The Rakyat Post say the rear hold carried goods above the maximum load, described as items such as golf equipment and televisions bought in the free port of Labuan; the declassified report itself is reported as recording that weight limits were observed while the loading distribution was outside limits.
contested
Whether the timing of the 14 June 1976 petroleum agreement is connected to the crash. The closeness of the signing to the deaths has been raised publicly as a question, which Harris Salleh addressed directly in June 2026: he has said the Petroleum Development Act and the 5 per cent payment were federal matters settled in Parliament with Sabah and Sarawak representation, that the state cabinet's role was only to take note, and that Fuad Stephens supported the arrangement.
contested
Whether Fuad Stephens would have accepted 5 per cent. Conrad Mojuntin has said Fuad Stephens would never have agreed to that figure; Harris Salleh has said Fuad Stephens fully supported the parliamentary arrangement. Joseph Pairin Kitingan has separately accused Harris Salleh of acting unilaterally, which Harris denies.

In June 2025, families said they had shelved proposed legal action, citing cost, time, fatigue and lack of backing.
