] QF30 was a scheduled flight from London Heathrow Airport to Melbourne Airport with a stopover in Hong Kong International Airport on July 25, 2008. The flight was interrupted because of a rapid decompression caused by a fuselage rupture just forward of the starboard wing root. There were no injuries and the plane made an emergency descent to a breathable altitude of about 10,000 feet and eventually made an emergency landing at Ninoy Aquino International Airport, Metro Manila, Philippines.

The flight left Hong Kong on July 25, 2008 shortly after 9:00 am HKT (0100 UTC).cite web

After the accident, numerous passengers said that some oxygen masks did not deploy, whilst others had deteriorated elastic. Consequently, it was reported that one passenger smashed a panel of the ceiling to attempt to gain access to the masks. It was stated that these passengers were deprived of oxygen until the plane was lowered to a breathable altitude. [cite news

The hole in the fuselage — roughly in an inverted T-shape — was up to 2.01 m wide and approximately 1.52 m high, located on the right side of the fuselage, below cabin floor level and immediately forward of the wing. The wing-fuselage fairing was missing, revealing some palletised cargo in the hold, however the freight forwarder reported that all items on the manifest were accounted for. Other than some items which were located near the cylinder and resulting hole, no other cargo or baggage on the flight was damaged.

The airline, in a news release, said there were no reports of injuries. [cite press release

Soon after the incident, the ATSB announced that air safety investigators found that an oxygen cylinder which was located in the area of the explosion hasn't been accounted for, but that it was too early to say that an oxygen cylinder could be the cause of the mid-air explosion on QF30. Regardless, the Civil Aviation Safety Authority ordered Qantas to inspect all of its oxygen cylinders and brackets which hold the cylinders on its Boeing 747 fleet. [cite news

On 30 July, the ATSB gave an update confirming further aspects of the initial investigation. They stated that these initial investigations had found that the aircraft took about five and half minutes to descend from the decompression event at 29,000 feet to the altitude of 10,000 feet and that it appeared that part of an oxygen cylinder and its valve had entered the passenger cabin, then impacted with the number 2 right door handle, turning it part way. The ATSB noted that there was no risk of the door being opened by this movement, with the door systems performing as designed. All three of the aircraft's instrument landing systems as well as the anti-skid braking system were unavailable for the landing; however, all evidence that had been assessed had indicated that the engines and hydraulics were operating normally. Most of the oxygen masks deployed in the incident, with 418 out of the 484 deployed being activated by the 346 passengers, pulling them down to activate the flow of oxygen.

The ATSB further indicated that the aircraft had some of its instrumentation fail, leading the pilots to choose a visual flight rules (VFR) landing. [cite news

Preliminary findings

The cause of the accident has been determined to be an exploding oxygen tank in the cargo area, according to a preliminary finding of the Australian Transport Safety Bureau:cite web

]

"After clearing the baggage and cargo from the forward aircraft hold, it was evident that one passenger oxygen cylinder (number-4 from a bank of seven cylinders along the right side of the cargo hold) had sustained a sudden failure and forceful discharge of its pressurised contents into the aircraft hold, rupturing the fuselage in the vicinity of the wing-fuselage leading edge fairing. The cylinder had been propelled upward by the force of the discharge, puncturing the cabin floor and entering the cabin adjacent to the second main cabin door. The cylinder had subsequently impacted the door frame, door handle and overhead panelling, before falling to the cabin floor and exiting the aircraft through the ruptured fuselage."

The ATSB has also issued two "Safety Advisory Notices", advising responsible organizations to review procedures, equipment, techniques and personnel qualifications for maintenance, inspection and handling of aviation oxygen cylinders.
