<section begin="summary" />Qantas Flight 32 was a scheduled service operating between London and Sydney, with a stopover in Singapore. On 4 November 2010, the flight’s Airbus A380 encountered an uncontained engine failure in one of its four Rolls-Royce Trent 900 powerplants. This event took place above the Riau Islands, Indonesia, just four minutes after departing from Singapore Changi Airport. Following nearly two hours in a holding pattern to evaluate the damage, the aircraft executed a successful emergency landing at Changi. Despite debris falling onto residences in Batam, no injuries were reported.

Examination revealed that the number-two engine (located on the port side near the fuselage) suffered a catastrophic turbine disc failure, which inflicted severe damage to the nacelle, wing structure, fuel system, landing gear, flight control systems, engine controls, and triggered a fuel tank fire that extinguished itself. The root cause was traced to a fractured stub oil pipe that had been manufactured incorrectly.

This incident marked the first failure of this kind for the A380 model, which at that time was operated by five airlines with a total of 39 aircraft: Qantas, Air France, Emirates, Lufthansa, and Singapore Airlines. As a result, Qantas temporarily grounded its six A380s and initiated inspections and engine replacements on certain Rolls-Royce-powered A380s with Lufthansa and Singapore Airlines. A380s operated by Air France and Emirates, equipped with Engine Alliance engines, were not impacted.<section end="summary" />

Accident

At 10:01 am Singapore Standard Time, while flying over Batam Island in Indonesia, an uncontained failure occurred in the port inboard (number-two) engine. The resulting shrapnel penetrated the wing, damaging the fuel system which led to leaks and ignited a fuel-tank fire. This event disabled one hydraulic system along with the antilock braking system, caused engines number one and four to switch into "degraded" mode, and impaired the landing flaps as well as controls related to the outer left number-one engine.

The flight crew established a holding pattern near Singapore Changi Airport to assess the aircraft’s condition, completing their evaluation within 50 minutes. They entered data into the landing distance performance application (LDPA) for a landing scenario approximately 50 tonnes above maximum landing weight; initially, no landing distance could be calculated. After removing inputs related to wet runway conditions, the LDPA verified that landing was possible with about 100 meters of runway remaining. The aircraft then returned to Changi and landed safely at 11:45 am using the gravity drop emergency extension system for its landing gear. The touchdown speed was 35 knots higher than usual, resulting in four blown tires.

After landing, the crew was unable to shut down engine number one; emergency personnel extinguished it by applying water until it flamed out. Fuel leakage near heated brakes on the left wing raised concerns about evacuation safety. David Evans, the supervising check captain, advised that remaining inside the aircraft was safest until conditions stabilized. Cabin crew were prepared to initiate evacuation immediately if necessary; ultimately, all 440 passengers and 29 crew members disembarked calmly using a single set of stairs. During this time, the aircraft operated solely on battery power with only one VHF radio available to coordinate emergency efforts.

No injuries were reported among those onboard. Debris from the failed engine fell onto a school, residential homes, and a vehicle on Batam Island.

Aircraft

The aircraft involved was an Airbus A380-842 bearing the registration VH-OQA and serial number 014. Delivered in September 2008, this was Qantas' inaugural A380 model, equipped with four Rolls-Royce Trent 900 engines. The plane was named Nancy-Bird Walton in honor of a pioneering figure in Australian aviation. After sustaining damage, it underwent repairs in Singapore with costs estimated around $139 million before returning to service in Sydney by April 2012.

Flight crew

Captain Richard Champion de Crespigny, the pilot in command, was recognized for his skillful handling of the severely damaged aircraft, successfully landing it at Singapore Changi Airport and preventing a major disaster. At the time, he had accumulated 35 years of flying experience and received commendations for his leadership throughout the event and for personally addressing passengers after the flight. In 2016, he was honored as a Member of the Order of Australia for his outstanding contributions to aviation safety and community service.

In 2010, Richard Woodward, vice president of the Australian and International Pilots Association, described the cockpit crew as comprising five pilots: the captain, co-pilot, a relief pilot, and two check captains (one undergoing training). Captain Champion de Crespigny concentrated on piloting and aircraft management, while the co-pilot managed monitoring duties and handled over 100 electronic centralised aircraft monitor (ECAM) checklists. The remaining pilots supported by overseeing procedures and assisting as required.

Stock markets

Following the incident, Rolls-Royce Holdings—manufacturer of the engines—experienced a 5.5% decline in share price to 618.5 pence on the London Stock Exchange, marking their largest drop in 18 months directly associated with the event. Shares of Airbus (then EADS) also decreased. By 8 November 2010, Rolls-Royce stock had fallen more than 10% since the occurrence.

Grounding of aircraft and replacement of engines

In response, both Qantas and Singapore Airlines—operators of A380s powered by identical Rolls-Royce engines—temporarily grounded their fleets to conduct inspections. Singapore Airlines resumed operations the following day.

Qantas identified problems with two engines on its remaining A380 fleet and planned replacements to avoid similar incidents. On 8 November, CEO Alan Joyce announced an ongoing grounding due to newly discovered engine issues including excessive oil leaks beyond acceptable limits. Initially reporting no concerns, Singapore Airlines later revealed on 10 November intentions to replace three engines across three aircraft, grounding those planes until repairs were completed. Lufthansa also preemptively replaced an engine on its first A380 as a safety measure.

By 3 December, Qantas disclosed that repairs or replacements were necessary for 16 Trent 900 engines, with five already completed.

On 23 November, Qantas began a phased return of its A380 fleet to service by deploying two out of six aircraft on Sydney–Singapore–London routes where reduced thrust sufficed. The airline refrained from using these aircraft on longer Los Angeles–Australia flights requiring maximum engine power until safety was confirmed by manufacturers and regulators. Full service on these routes recommenced in January 2011. By late January, all but one A380 were operational; the damaged VH-OQA returned to active duty in April 2012.

Responses on importance

Tom Ballantyne from Orient Aviation described the event as "the most critical incident the A380 has faced since commencing operations," expressing worries about a possible "significant issue" extending beyond routine maintenance. On 5 November, Qantas CEO Alan Joyce suggested that the probable cause involved "some form of material defect or design flaw."

The damage, characterized by The Sydney Morning Herald as "extremely rare and potentially life-threatening," led aircraft engineer Peter Marosszeky of the University of New South Wales to comment, "Failures of this nature are seldom observed in any engine." Paul Cousins, federal president of the Australian Licensed Aircraft Engineers Association, noted that "less than 5% of engine failures result in debris escaping the casing," as occurred in this case.

Author and human-factors specialist Carey Edwards commended the QF32 crew, calling it "one of the most exemplary demonstrations of airmanship in aviation history."

Service background

This Airbus A380 incident followed two earlier occurrences involving Rolls-Royce Trent 900 engines: a September 2009 failure on a Singapore Airlines flight from Paris to Singapore and an August 2010 engine shutdown due to low oil pressure on a Lufthansa Tokyo-Frankfurt route. Additionally, in September 2017, an Air France A380 equipped with Engine Alliance turbofans (manufactured by General Electric Aircraft Engines and Pratt & Whitney) suffered an engine failure while flying from Paris to Los Angeles.

In response to these incidents, the European Aviation Safety Agency issued an airworthiness directive on 4 August 2010 mandating thorough inspections of Rolls-Royce Trent 900 engines.

Investigation

The Australian Transport Safety Bureau (ATSB) investigation uncovered "fatigue cracking" within a stub pipe of the Rolls-Royce Trent 900 engine, which caused oil leakage and subsequent fire, ultimately resulting in the release of the intermediate-pressure turbine (IPT) disc. This fault was unique to the Trent 900 model.

Rolls-Royce identified the root cause as a misaligned counter bore in a stub oil pipe leading to fatigue fracture. The ATSB's preliminary findings corroborated this conclusion.

Airbus reported that the IPT disc released three high-velocity fragments that inflicted structural damage and severed segregated wiring paths, which prevented shutting down engine one after landing.

On 10 November 2010, the European Aviation Safety Agency issued an emergency airworthiness directive requiring frequent inspections of Trent 900 engines, including ground idle runs and blade checks. By 22 November, EASA relaxed inspection demands following progress in investigations.

On 2 December 2010, the ATSB advised a one-time inspection of affected Trent 900 engines within two flight cycles.

The ATSB's preliminary report released on 3 December emphasized a manufacturing defect: fatigue cracking in the stub pipe supplying oil to the HP/IP bearing structure caused oil leakage, an engine fire, and failure of the IPT disc. The counter-boring misalignment resulted in a thin pipe wall susceptible to fatigue fracture.

This defect was classified as a serious safety concern, leading to immediate inspections of all operational Trent 900 engines. By 8 December, inspections had been completed on 45 engines; three were found defective and removed from service. An interim ATSB report in May 2011 indicated that 53 Trent 900 engines had been withdrawn—11 due to out-of-tolerance oil-feed stub pipes and 42 because of missing measurement documentation.

The event revealed shortcomings in alert systems; over 80 ECAM warnings were triggered, requiring more than an hour for resolution.

Compensation and Repairs

On 22 June 2011, Qantas obtained a settlement of AUD 95 million (equivalent to GBP £62 million / US$100 million) from Rolls-Royce. The aircraft VH-OQA underwent restoration work valued at around AUD 139 million (~US$145 million), which included the installation of four new engines and refurbishment of the left wing, involving replacement of approximately 6 km of wiring. Following comprehensive ground evaluations and two test flights, the plane was flown back to Australia on 22 April and recommenced operations on 28 April 2012. These modifications resulted in an increase of roughly 94 kg in the aircraft’s maximum takeoff weight.

Airworthiness Directive

During the repair process, wing cracks were detected, leading to the issuance of an airworthiness directive impacting 20 A380-841, A380-842, and A380-861 models with flight hours exceeding 1,300. Aircraft with fewer than 1,800 hours were mandated to undergo inspections within six weeks or after 84 flights; those with more than 1,800 hours required checks within four days or after 14 flights. On 8 February 2012, the scope of inspections was broadened to encompass all 68 A380s currently in service.

Dramatisations and Publications

The Qantas 32 event was dramatized in the Canadian television series Mayday, specifically in Season 13, Episode 10 titled "Titanic in the Sky". Captain Richard de Crespigny authored two books recounting the flight, published in 2012 and 2018 respectively. Moreover, a drama documentary featured in the British series Terror at 30,000 Feet (Season 1, Episode 2) was produced by Raw Cut Productions Ltd for Channel 5 and broadcast on 26 July 2024; it includes interviews with pilots, cabin crew, and passengers involved.
