From the Wikipedia article

The 1985 accident of a Thai Airways Boeing 737 near Phuket occurred on 15 April 1985. On that day a Boeing 737-2P5, which was operating a Thai domestic scheduled flight of Thai Airways from Bangkok-Don Mueang Airport to Phuket Airport, collided with a mountain, killing all 11 occupants of the aircraft.

Accident sequence

The aircraft's takeoff in Bangkok and the flight towards Phuket initially proceeded without any particular incidents. Four minutes after the pilots had received clearance to descend to 3,000 feet for the approach to Phuket, the captain reported that he could not receive a DME signal. At 23:24 air traffic control in Phuket asked the pilots whether they would prefer to carry out a VOR approach to runway 09 instead of a visual approach to runway 27. At the pilots' request the approach to runway 27 was continued, until a little later the captain reported that during the descent at an altitude of 3,400 feet both engines had failed and the aircraft had almost collided with a mountain. On final approach the aircraft finally collided with a mountain at 23:30 at a height of 800 feet. All eleven occupants were killed.
