SAS is quite correct. Due to a spindle failure, a main rotor blade flew off both those 76s. One was on about a 1 mile final to an oil rig in South America & killed all 14. The Bristow 76 was on a training flight with 2 pilots & 2 farmer pax on board doing IF practise over Longside. The tail rotor problem killed 14 off Songkla much later. All those problems were fixed long ago.
