NTSB Narrative Summary Released at Completion of Accident

On August 2, 2005, at 1757 local time, a Boeing 777-200, registered in Malaysia as 9M-MRG, operated by Malaysian Airline System, experienced a pitch up about one-half hour after takeoff from Perth, Australia. This event occurred as the flight was climbing through 36,000 feet and while the aircraft was on autopilot. During the pitch up the aircraft climbed to 41,000 feet and the indicated airspeed dropped from 270 knots to 158 knots. The stick shaker and the stall warning indicator activated during the event. The flight landed uneventfully back at Perth. On August 29, 2005, the FAA issued emergency AD 2005-18-51 that superceded an earlier airworthiness directive. It states that operators should install ADIRU-03 software within 72 hours in their Boeing 777 aircraft. It also states that faulty ADIRU data could cause anomalies in 777 primary flight controls, autopilot, pilot displays, autobrakes and autothrottles. The investigation is under the jurisdiction of the Government of Australia.
