Latest issues come at an inopportune time for Airbus who is trying to fight off Boeing's superjet entrant
Australian Licensed Aircraft Engineers Association
(ALAEA) is sounding the alarm on one of the world's most iconic passenger aircraft designs, claiming that they are suffering from a design flaw.
The aircraft in question is the Airbus A380, the world's largest passenger jet. The four-engine aircraft is manufactured by Airbus, a subsidiary of The European Aeronautic Defence and Space Company N.V. (EADS) (
The airplane, which saw its maiden flight in April 2005, and saw an Oct. 2007 commercial introduction, has enjoyed having no real peer over the last several years, as it offers almost 50 percent more floor space than The Boeing Comp.'s (BA) 747-400. It packs 478 square metres (5,145.1 sq ft) of floor space. The A380-800 variant has a range of 15,400 kilometres (8,300 nmi; 9,600 mi) and has a cruising speed of Mach 0.85 (about 900 km/h or 560 mph at cruising altitude), meaning that it can travel from Hong Kong to New York City, without refueling, in only 17 hours.
But according to the Australian engineering group, the deployed aircraft show cracking in their wing ribs. Steve Purvinas, secretary of the ALAEA, comments, "We can't continue to gamble with people's lives and allow those aircraft to fly around and hope that they make it until their four-yearly inspection."
The cracks were first found on A380s deployed in the fleets of Singapore Airlines (
) and Qantas Airways (
) (which primarily operates out of Australia). The two airlines account 26 out of the 50 delivered passenger A380-800s, as the second and third largest A380 users.

So far no American airline company has adopted A380. FedEx Corp. (
) and United Parcel Service, Inc. (
) placed commercial orders, but
after being inconvenienced by delays from the aircraft-maker.
Airbus representatives as confirming the wing rib cracking, but insist it's harmless, and that passengers shouldn't be worried about the cracking wings. States the company, "We confirm that minor cracks were found on some noncritical wing rib-skin attachments on a limited number of A380 aircraft. We have traced the origin. Airbus has developed an inspection and repair procedure, which will be done during regular, routine scheduled four-year maintenance checks. In the meantime, Airbus emphasizes that the safe operation of the A380 fleet is not affected."
Qantas has thus far repaired two of the members of its fleet that it spotted cracks in.
The A380 had been being considered as a
possible upgrade option
for the President of the United States' plane, Air Force One. This is not the first issue to afflict the craft -- earlier
wiring issues delayed shipments
of the aircraft.
The cracking issues are bad timing for Airbus. The company is currently trying to sell new customers on the aircraft and ward off Boeing, who
just unveiled the Boeing 747-8 Intercontinental
, a craft that finally brings Boeing abreast of Airbus in the mega-aircraft department. The 747-8
took its maiden flight in Feb. 2010

A few points
1. Airframes currently do not have a mandated retirement limit. There are manufacturer's suggested lifespans. The FAA is working on a mandated retirement limit. The limit will be different for different airframes. For something as large as an A380, the limit would likely be 30,000-40,000 flight cycles. (Due to the large oval nature of the airframe, the stress caused by internal pressure will be high.)
2. The existence of cracking does not show a problem. The size of cracking in this case is suggesting a potential problem. Likely there is an installation issue, which is resulting in high local fatigue stresses/stress corrosion.
3. Errrr.... While something may not be a load bearing area, that doesn't mean it is not important. The aerodynamic surface of the wing is -very- important is several areas. For example, the leading edge. A panel failure of the leading edge can make certain maneuvers difficult/impossible. If the pilot is unaware of potential issues, he would be faced with a difficult situation where his instruments and computer are telling him there is a problem, but he has no real knowledge of his new limitations.
Potentially, if the A380 computer system is sensitive enough to detect changes in airflow over the wing and inform the pilot of their changed flight envelope, I can agree that this issue is relatively minor. But Civil Aviation Agencies typically don't talk out like this unless there is a relatively high danger.
"We are going to continue to work with them to make sure they understand the reality of the Internet. A lot of these people don't have Ph.Ds, and they don't have a degree in computer science." -- RIM co-CEO Michael Lazaridis
