[2] The crew requested an instrument landing system approach to runway 09 and that they would follow the back beam procedure.

[2] The Air Traffic Control informed them the procedure was not available and they should carry out an approach using the VOR beacon.

[2] The controller advised them that they might encounter heavy turbulence if they went more than six or seven miles (5.2 or 6.1 nmi; 9.7 or 11.3 km) west of the airport.

[2] Permission was granted and the aircraft, already in severe turbulence, entered a left-hand turn and then crashed into the sea at 1:50 a.m., nine nautical miles (10 mi; 17 km) from Madh Island.

[2] Because no wreckage was salvaged and the crew did not report any problems, it was concluded that the aircraft was probably lost due to loss of control while turning in severe turbulence and heavy rain.
