Beschrijving:
The Learjet crew consisted of an instructor and a trainee pilot. For the short flight from Phuket to Ranong the crew were supposed to carry out the approach briefing before takeoff. They failed to do so, which left them little time en route to carry out the procedure and cross-checking the distance and altitude during the flight. The instructor misinterpreted the Ranong DME distance and caused the trainee pilot to descend below minimum sector altitude in unfavourable weather conditions. The aircraft consequently flew into high terrain.
