Last week's mid-air emergency off Singapore also badly damaged a wing, which may have to be replaced.

A full list of the damage to the Airbus A380 has been revealed after it was nursed back to Singapore on three engines.

When it touched down the fuel systems were failing, the forward spar supporting the left wing had been holed and one of the jet's two hydraulic systems was knocked out and totally drained of fluid.

Sources compared flight QF32 to the Memphis Belle, the World War II bomber that became the subject of a fictional award-winning 1990s Hollywood movie by the same name. The film portrayed the heavily damaged aircraft landing in England after a bombing raid on Germany.

Richard Woodward, vice-president of the International Air Pilots' Federation, told the Herald Sun yesterday that the lesson from the near disaster was the value of an experienced flight crew.

"There was a wealth of experience in the cockpit, even the lowest ranked officer on board had thousands of hours of experience in his former role as a military flying instructor," said Capt Woodward, himself an A380 pilot on leave from Qantas.

As another senior pilot said: "It is bad enough for an engine to explode in mid-air let alone lose so many secondary systems".

Investigators found shrapnel damage to the flaps, a huge hole in the upper surface of the left wing and a generator that was not working.

The crew could not shutdown the No. 1 engine using the fire switch.

As a result the engine's fire extinguishers could not be deployed.

Captain Richard de Crespigny, first officer Matt Hicks and Mark Johnson, the second officer, could not jettison the volume of fuel required for a safe emergency landing.

With more than 80 tonnes of highly volatile jet kerosene still in the 11 tanks -- two of which were leaking - they made an overweight and high speed approach to Changi Airport.

Without full hydraulics the spoilers - the hinged flaps on the front of the wings - could not be fully deployed to slow the jet.

The crew also had to rely on gravity for the undercarriage to drop and lock into place.

On landing they had no anti-skid brakes and could rely on only one engine for reverse thrust - needing all of the 4km runway at Changi to bring the jet to a stop.

The three crew have been interviewed by Australian investigators and cleared to return to duties.

Industry sources said the damage will almost certainly put the airline's flagship jet - the Nancy-Bird Walton - out of service for months.

Investigators found that an oil fire may have caused the engine to explode.

Details of the stricken jet's problems were revealed yesterday in an emergency directive by the European Aviation Safety Authority.

The authority made it mandatory for airlines with the now suspect Rolls-Royce Trent 900 engines to make checks for excess oil.

If not detected, excess oil can cause a fire and ultimately result in "uncontained" engine failure, with potential damage to the aeroplane and to people or property on the ground.

Qantas made it clear it will keep its six superjumbos grounded indefinitely and has rearranged flight schedules using substitute aircraft.

"The specific checks mandated by the directive were already being carried out by Qantas in conjunction with Rolls-Royce," it said.

"Qantas's A380 aircraft will not return to service until there is complete certainty that the fleet can operate safely."


1 Massive fuel leak in the left mid fuel tank (there are 11 tanks, including in the horizontal stabiliser on the tail)

2 Massive fuel leak in the left inner fuel tank

3 A hole on the flap fairing big enough to climb through

4 The aft gallery in the fuel system failed, preventing many fuel transfer functions

5 Problem jettisoning fuel

6 Massive hole in the upper wing surface

7 Partial failure of leading edge slats

8 Partial failure of speed brakes/ground spoilers

9 Shrapnel damage to the flaps

10 Total loss of all hydraulic fluid in one of the jet's two systems

11 Manual extension of landing gear

12 Loss of one generator and associated systems

13 Loss of brake anti-skid system

14 No.1 engine could not be shut down in the usual way after landing because of major damage to systems

15 No.1 engine could not be shut down using the fire switch, which meant fire extinguishers would not work on that engine

16 ECAM (electronic centralised aircraft monitor) warnings about the major fuel imbalance (because of fuel leaks on left side) could not be fixed with cross-feeding

17 Fuel was trapped in the trim tank (in the tail)creating a balance problem for landing

18 Left wing forward spar penetrated by debris
