Flying Tigers Line Flight 66
Flying Tigers Line Flight 66 was a cargo flight from Singapore to Hong Kong via Kuala Lumpur. Malaysia. On February 19, 1989, the FedEx-owned Boeing 747-249F-SCD crashed while on its final approach. All four crew members were killed.  The First Officer (FO), who was the pilot flying at the time, expressed concern about conducting the NDB approach and indicated a preference for the ILS for runway 15. However, the FO was not assertive and no further action was taken. The Captain dismissed his concern saying he was familiar with the airport and the approaches.  ATCO: "Tiger 66, descend two four zero zero [2,400 ft]. Cleared for NDB approach runway three three."  The captain of Tiger 66, who heard "descend to four zero zero" replied with, "Okay, four zero zero" (meaning 400 ft above sea level, which was 2,000 ft too low).   The proper radio call from ATC (instead of "descend two four zero zero") should have been "descend and maintain two thousand four hundred feet". The captain read back "okay, four zero zero" where the proper read back should have been "Roger, descend and maintain four-hundred feet".   The Cockpit voice recorder also revealed several communication errors made by the flight crew prior to this miscommunication and a general casual nature of the Captain, who was the pilot-not-flying on this particular leg of the trip.
