The investigation by the Australian Transport Safety Bureau (ATSB) indicated that "fatigue cracking" in a stub pipe within the engine resulted in oil leakage, followed by an oil fire in the engine.[48] The fire led to the release of the intermediate-pressure turbine (IPT) disc. It also said the issue is specific to the Trent 900.[49]
On 3 December 2010, the ATSB issued a preliminary report that contained a key finding of a manufacturing flaw: An area of fatigue cracking was found within a stub pipe that feeds oil to the engine HP/IP bearing structure.[9] Bearing lubricating oil leaked from the crack, causing the subsequent engine fire and failure of the IPT disc. The fatigue fracture was a result of the misalignment of the stub pipe during the counter-boring process. That inaccurate alignment resulted in one side of the same stub pipe becoming too thin to resist fatigue fracturing.[9][54] This "could lead to an elevated risk of fatigue crack initiation and growth, oil leakage, and potential catastrophic engine failure from a resulting oil fire," according to the agency.[54]
During repairs following the occurrence, cracks were discovered in the wings of the aircraft. As a result of the discovery, an airworthiness directive was issued affecting 20 A380-841, A380-842 and A380-861 aircraft that had accumulated over 1,300 hours flight. Those aircraft with under 1,800 hours flight were to be inspected within 6 weeks or 84 flights (whichever occurred first), while those with more than 1,800 hours flight were to be examined within four days or 14 flights.[59][60] On 8 February 2012, the checks were extended to cover all 68 A380 aircraft in operation.[61]
More than ninety vessels and aircraft from Indonesia, Singapore, Malaysia, Australia, South Korea, Japan, China, the United States, and Russia participated in the search.[58][59][60] This fleet included three ships with underwater detectors and two fuel tankers seconded to ensure efficient operation of the vessels in the search area.[61] On 2 January the Indonesian Ministry of Transport reported that two other Indonesian tender vessels had been fitted with equipment that could detect acoustic signals from the flight recorder ("black box") beacons and airframe metal, as well as multibeam side scan sonar.[62]
The example of miscommunication between the pilots was when the plane was in a critical stalling condition, the co-pilot misunderstood the captain's command "pull down"; instead of pushing the airplane's nose down (pushing forward on the stick to regain speed and escape the stall), he pulled the stick back, which would have ordered the aircraft to pitch up, deepening the stall. Because the captain was also pushing the stick forward and because Airbus has a dual-input system, the two stick inputs cancelled each other out, which led to the plane remaining in a stall condition until the end of the black box recording.[citation needed]

Before 2003, the highest government officials traveled in an Air Force 707, which also served as a refueling plane and was rumored to be uncomfortable. In 1997, a window cracked while Netanyahu was on board, so the pilot had to fly at a low altitude.31 2b1af7f3a8
