Qantas plane turns back after landing gear problem


October 29, 2008 - 5:34PM


A Qantas flight from Melbourne to Sydney has been forced to turn around and return to Melbourne airport after the pilot was alerted to a possible landing gear malfunction.


The Boeing 767 with 244 passengers on board had only just taken off at 1.29pm when the landing gear fault light came on in the cockpit.


The pilot immediately turned the plane around and returned to Tullamarine airport, landing safely at 2.15pm.


A Qantas spokesman said passengers were not in danger, and that Qantas engineers were inspecting the aircraft to determine the cause of the alert.

A replacement aircraft has been organised for the passengers, but their arrival time will be delayed by two hours.


It is the second landing gear issue on a Qantas jet in the last three months.


On July 29 a Qantas 767 was forced to make an emergency landing after a landing gear door malfunctioned.

Did naval base signals make Qantas jet nosedive?

The Qantas jet plummeted hundreds of feet, injuring passengers

Powerful signals from a US-Australian naval base might have caused a Qantas jumbo jet to to plummet hundreds of feet last month, injuring scores of passengers, say investigators.


The Australian Transport Safety Bureau (ATSB) is also examining whether a passenger's laptop might have interfered with the plane's computer system, according to the preliminary report into the incident where the passenger flight from Singapore to Perth suddenly nosedived from the sky twice in the space of minutes.


ATSB capability director Kerryn Macaulay said on Friday that investigators were looking into whether outside interference caused the plane’s computer system to malfunction mid-flight.


“Possible external sources of electromagnetic interference are being explored and assessed, including from the Harold E. Holt very low frequency transmitter near Exmouth, WA, and from portable electronic devices on board the aircraft,” she said.

However Ms Macaulay added that transmissions from the naval base were “unlikely” to be the source of the problem, that it was more likely to have been a glitch in the plane’s computer system units, known as Air Data Initial Reference Units (ADIRU).


The manufacturer of the three ADIRUs on the Airbus will begin testing the components in the US on Monday.


"A carefully prepared test plan is currently being finalised in anticipation of this complex work to ensure the investigation team has the best possible chance to understand what led to the pitch-down events," Ms Macaulay said.


The pilots issued a mayday call when the Airbus, with 303 passengers onboard, plunged 1000 ft in just over a minute on October 7.


They managed to land the plane safely at Learmonth airport near the remote coastal town of Exmouth, 1,200km north of Perth. However 13 passengers and one crew member were seriously injured and some were airlifted to hospital in Perth.


The top-secret naval base at Exmouth transmits signals to US and Australian navy ships, including nuclear submarines, in the Pacific and Indian oceans.


The station, on Australia's north-west coast, is the most powerful transmission station in the Southern Hemisphere and has been a frequent target of peace protests since it opened in 1963.


The tallest of the station's 13 radio towers stands 1,270 feet tall — higher than the top floor of New York's Empire State building.


The Defence Department said it agreed with the preliminary report that the transmitter was unlikely to be the cause.


The transmitter “emits very low frequency transmissions and from a significant distance from the aircraft flying overhead,” the department said in a statement.


“This indicates that it is unlikely to have caused sufficient currents in the system to have caused problems with the A330 systems,” it added.


Qantas said its own investigations found the likely cause of the emergency was a “manufacturer fault” in the computer units.


Last month the ATSB and Airbus issued emergency guidelines to airlines worldwide operating the Airbus A330-300 in the event of a similar emergency.


The ATSB is investigating the incident alongside its French and US safety investigation counterparts.


The incident was one of a series which have recently plagued Qantas, Australia’s flagship international airline, long considered one of the safest in the world.


The most serious occurred in July when a Qantas jumbo jet, en route from London to Melbourne was diverted to Manilla after a gas cylinder on board exploded mid-air, ripping a massive hole in the fuselage. Miraculously nobody was seriously injured.

Radar failure forces Qantas flight to turn back

A Shanghai-bound Qantas flight was forced to return to Sydney Airport yesterday after its radar systems malfunctioned, the second radar failure experienced by the airline in two weeks.


In the latest incident involving the airline, QF129 - an Airbus A330-300 carrying 278 passengers - had to return to Mascot an hour into its journey.


Qantas confirmed this morning the malfunction had only affected the aircraft's weather radar, not its navigation system.


Passengers told the Herald the pilot had announced that "both radar systems" were not working - a reference to the fact planes have two onboard weather radar systems.


A similar problem forced QF12 to "piggyback" behind an Air New Zealand aircraft for virtually its entire journey from Los Angeles to Sydney on October 29.


Passengers from yesterday's flight told the Herald that the initial 11.30am take-off had been delayed for more than an hour due to "mechanical difficulties".


Around 3pm the aircraft began a sweeping 180-degree turn and headed back to Sydney. The plane spent about an hour in a holding pattern while dumping its heavy fuel load to allow a safe landing.


"The pilot definitely told us that both radar systems had failed," one passenger said. "He said we had to turn back because he couldn't fly over Indonesia without the radar systems."


There were a large number of storms over Indonesia at this time of year, which meant it was crucial to have functioning weather radar systems in order to fly safely, said a senior pilot with the Australian and International Pilots Association.


With both systems having failed, the safest option was to return to Mascot, he said.


Having had their travel plans disrupted, passengers had to wait for about four hours for a replacement aircraft.


The flight was due to take-off at 7pm, but passengers reported more delays due to mechanical problems with the replacement plane, with Qantas providing passengers with a $20 dinner voucher.


"Tonight was supposed to be special," the passenger said. "I'm only going to Shanghai for three nights, so I've effectively missed the main reason for going. It's a sad reflection on Qantas and a lot of passengers are saying they won't fly on Qantas again."
