Flight PA-812 was a scheduled international flight from Hong Kong (HKG) to Sydney (SYD), Australia with an intermediate stop at Denpasar (DPS), Bali.
The crew prepared for an approach to runway 09 at Denpasar. The airplane descended to an altitude of 2500 feet when it flew into the side of a mountain.
It appeared that the crew had initiated the let-down procedure after one of the ADF needles swung. The other needle remained steady, but the crew assumed that they were over the beacon when the aircraft was still about 30 NM North of the beacon.
Probable Cause:PROBABLE CAUSE: "The premature execution of a right-hand turn to join the 263 degrees outbound track which was based on the indication given by only one of the ADFs while the other one was still in steady condition"
