United Arab Airlines Flight 869 (1963)

At 1:46 a.m. in Mumbai on 28 July 1963 (20:16 GMT on 27 July), the Comet crew reported being overhead the Santa Cruz VOR beacon at 7000 feet and were cleared to descend to 4000 feet.[2] The crew requested an Instrument Landing System approach to Runway 09 and that they would follow the back beam procedure.[2] The controller advised them the procedure was not available and they should carry out an approach using the VOR beacon.[2] The crew agreed to use the procedure and reported leaving 7000 feet in the descent on the 272-degree radial from the VOR.[2] The controller advised them that they might encounter heavy turbulence if they went more than six or seven miles west of the airport.[2] The crew requested a left-hand procedure rather than the more normal right-hand one because of the weather.[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 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.[2]
