Conoco

Gulfstream GII

The aircraft departed Tokyo-Narita Airport on a flight to Jakarta with a fuel stop at Kota Kinabalu Airport, carrying nine passengers and three crew members, among them four corporate members of the Conoco Group that leased the aircraft from DuPont de Nemours. Following an uneventful flight from Tokyo, the crew started the descent to Kota Kinabalu after being cleared to 10,000 then 5,000 feet. ATC instructed the crew to follow a route to the south (180°) and after passing VJN VOR at 4,000 feet, the crew could expect a clearance for an approach to runway 02. While descending to 4,000 feet, the aircraft disappeared from radar screens after it struck the slope of a mountain located in the Crocker Mountain Range, about 9 km northwest of Keningau and 57 km south of Kota Kinabalu Airport. The aircraft was destroyed upon impact and all 12 occupants were killed.

Grumman G-159 Gulfstream I

On approach to Houston-William P. Hobby Airport, a low oil pressure in the right engine gearbox forced the crew to shut down the engine and to feather its propeller. For unknown reason, the propeller was not properly feathered and the airplane was approaching too low and too fast. After touchdown, as the airplane already rolled half of the landing distance (7,600 feet), the captain decided to initiate a go-around. After liftoff, fire was observed coming out from the tail exhaust pipe while the left engine lost power. The crew attempted an emergency landing and completed a belly landing in an open field near the airport. All 20 occupants were rescued, among them a passenger was seriously injured. The aircraft was written off.
