Qantas flight 32 air crash investigation, Air Titanic in the sky

Updated: Sep 8, 2021

Qantas flight 32 take-off from Singapore to Sydney on 4th November 2010 with 29 crew and 440 passengers on board - Air titanic in the sky!

Flight Details:

Let’s get to the flight details, the aircraft involved is Airbus A380-842. The airplane started its service for Qantas in September 2008, it was the first A380 that Qantas started operating and it was equipped with Rolls Royce Trend 900 engines. It was named as Nancy-Bird Walton in memory of an Australian aviator. Qantas Flight 32 was repaired in Singapore, and it was valued at a total of $140 million and after the repair work, the aircraft returned to Sydney in April 2012.


Flight Crew details:

Qantas flight 32 consisted of five pilots in the cockpit which included the captain, the first officer, and the second officer, and 2 additional check captains.

  1. In total there were 3 captains consisting of a Flight captain, senior check pilot, and secondary check pilot.

  2. Flight Captain focused on flying and managing the aircraft, and

  3. Electronic centralized aircraft monitor (E-Cam) checklists were monitored by the first officer. Both the check pilots were monitoring the flight behavior and the stability of the aircraft.

Air Titanic in the sky - Accident details:

The crash occurred at 10:01 a.m. Singapore Standard Time, while passing through Bottom Island, Indonesia, due to an uncontrolled failure of the onboard number 2 engine.


In-flight 32 one small Fracture was made from the engine, then within a few minutes damaged the fuel system, causing leaks and fuel tank fire, disabling a hydraulic system and anti-lock braking system. controls for damaged landing flaps and external left side Number 1 engine.


The team, which found control of the aircraft, decided to fly a capture pattern while assessing the aircraft's position near Singapore's Changi Airport.


It took around 50 minutes to complete this initial stage.

The first officer and Senior Check Captain have placed the aircraft in the Landing Distance Performance Application with a maximum landing weight of 50 tons in Changi.


Based on these inputs, the Landing Distance Performance Application could not calculate the landing distance. After the deep discussion, the team chooses to remove the entries related to the wet runway and after the runway was dry.


Then the Landing Distance Performance Application’s returned the info on the 100m runway that landing was possible.


The plane returned to Changi Airport at 11:45 a.m. Singapore time after staff expanded landing gear through the Gravity Drop Emergency Expansion System.


And finally, the result of the plane landing 35 knots faster than normal, four tires were thrown.


Upon landing, the crew was unable to stop the number 1 engine, which had to be turned off by the emergency crew until the flame was burning.

They all are wondered if the plane could be ejected as soon as it landed because fuel leaked from the left near the brakes, which is considered too hot from the maximum brake. Senior Check Captain(SCC) pilot David Evans, said that “There is a situation where hot brakes, the fuel leakage, and the aircraft’s engine cannot be shut down by us (crew). There was a safe place on the plane until things changed. So, we kept the cabin crew with the full-time warning phase ready to exit at any time, open the doors, and raise the slides. As time goes on, that risk is minimal, and thankfully, we are lucky to be able to get everyone out so quietly and so systematically through a quiet staircase.”


The plane was battery-powered and had to fight with only one Very High Frequency (VHF) radio to coordinate emergency procedures with the local fire brigade.


One of the amazing news is the incident is that there were no injuries to the total 440 passengers and 29 crew on board. Anyway, this is the complete Qantas flight 32's accident detail and now let's get to go to the investigation part.

Investigation:

An investigation by the (ATSB) Australian Transport Safety Bureau found that a "fatigue cracking" in the “stub pipe” inside the engine led to an oil leak, which was followed by an oil fire in the engine.


The fire led to the release of the (IPD) Intermediate Pressure Turbine disk. It also said the issue was referred to Trend 900.


The direct cause of the Rolls Royce oil fire and mechanical malfunction was the improperly designed counterfoil inside a stub oil tube, which led to fatigue breakdown. Australian Transport Safety Bureau’s preliminary investigation report confirmed Rolls-Royce's findings.


Airbus released 3 different high-power pieces of the Intermediate Pressure Turbine disk, resulting in structural and system damage.

Separate wiring paths were disconnected from 2 of the 3 separate disk tracks, resulting in the machine not being able to close number one after landing.


On 10 November 2010, the European Civil Aviation Authority issued an emergency air traffic order, ordering airlines to conduct frequent and rigorous tests using the Trend 900 engine,

  • Low-pressure turbine stage-one blade,

  • Extended ground idle runs,

  • Case drain inspections,

  • Intermediate pressure or high-pressure (structure air-buffer cavity), and

  • Oil-service tube inspections

On 22nd November 2010, The European Union Authority for aviation safety relaxed its study guidelines, citing progress in the investigation. This dropped the need for re-inspection of extended ground passive runs and LPT Stage-One blades and case drain.


On 2nd December 2010, ATSB recommended a one-time inspection of "related" Trend 900 engines within 2 air cycles.

On 3rd December 2010, The Australian Transport Safety Bureau(ATSB) released a test report that contained the main key finding of a production defect and a fatigue crack was predicate inside the oil supply stub pipe to the engine Intermediate pressure or high-pressure bearing structure.


The lubricating oil leaking from the crack caused a subsequent engine fire and Intermediate Pressure Turbine disk failure.

Bore breakage is the result of the incorrect design of the stub pipe during counter-boring operation. With that misalignment, one side of the same stub pipe became too thin to resist fatigue breakage.


This could lead to "Fatigue cracks start and develop, leading to a risk of the oil spill and also the consequent catastrophic engine failure from an oil fire," then the company said that the findings were determined to be a “Very critical safety issue" and recommended an immediate inspection of the Trend 900 engines in The Australian Transport Safety Bureau service.


On 8th December 2010, The Australian Transport Safety Bureau released 45 reported that the Trend 900 engines had been tested and that all 3 engines had failed the test and had been removed from service.


On 18th May 2011, Again the Australian Transport Safety Bureau issued an interim factual report stating that 53 Trend 900 engines had been taken out of service, then 11 intolerant oil-feed stub tubes and then 42 oil-less calibration logs to feed the stub tube.

Overview Qantas flight 32 :

On 4th November 2010, The world’s longest Airbus A380 - 842 (Qantas Flight 32) takes off from Singapore on its way to Australia(London to Sydney). Within 4 minutes of the aircraft's departure, one of its(aircraft’s) engines exploded, and things got worse. Avalanche cockpit flooding system also failure warnings. At that time, the pilots were confused but had no time to hesitate or wasting. 440 passengers and 29 crew are in danger and they must return to Changi Airport in Singapore immediately.

Anyway, This is the short story of this world’s longest Airbus A380 - 842 Qantas Flight 32 and Qantas flight 32 air crash investigation into a new technological or into one of the most innovative or creative, and world’s longest aircraft in the world failed so wonderfully.


Anyway, it is time to conclude this Qantas flight 32 air crash investigation, the entire incident of QF32 was concluded that the failure was due to an improperly made stub that broke the oil pipe. One of the facts is the first time the A380, the world's largest passenger aircraft, has failed.
