Wing Cracks Found On Some A380 Wing Rib Feet

Engineers' Union Says All Aircraft Should Be Checked Quickly, Airbus And Airlines Downplay Safety Risks

The Australian Licensed Aircraft Engineers Association (ALAEA) has called for the inspection of all A380s flying for Qantas and other carriers after small cracks were found in the wing-rib attachments in some airplanes. The online news site Stuff.nz.co reports that Qantas discovered the cracks on one of its airplanes undergoing "extensive repair," and Airbus confirmed that the problem has cropped up in five superjumbos. Along with the Qantas airplane, one Emirates aircraft and two belonging to Singapore Airlines have wing-rib attachment cracks. The fifth airplane is a development platform belonging to Airbus.
Airbus and the airlines all say their flagship airplanes are completely safe to fly. Airbus said it will be issuing a service bulletin later this month requiring airlines to check the jets for the problem during their scheduled four-year heavy maintenance. The ALAEA, however, said the inspections should be done "as soon as possible."
The Associated Press reports that Singapore Airlines says its two A380s have already been repaired, though no specifics of the procedure were given. The airline said the cracks were found on "a small number of wing rib feet," which are the attachment points for the wing skin to the substructure. The ALAEA called the repairs a "band-aid" approach to the problem.
The Sydney Morning Herald reports that Airbus'  chief engineer Charles Champion said the cracks were less than a centimeter in length, and  told the paper that safety was not an issue because "there are so many ways for the loads to travel within the structure of the wing." He said that all A380s would be inspected "over time ... within the next four years. Some of them before."
Champion said that the cracks have nothing to do with the loads placed on the wings. He said the cracks were "very random." He said some airplanes had several cracks along both wings, while some had almost none.
EASA reportedly has no plans to issue an AD for the cracks, which Champion said shows that it is a "non-event."

    Begin forwarded message: From: beck8@comcast.net Subject: British Imperial Airways 1930's Date: January 14, 2014 10:36:14 PM EST            British Imperial Airways 1930's Flying the airlines in the thirties was a lot more fun than it is now. It was more leisurely and had more class. Certain elitist and anti-British people have no time for these period "rich types". People like these, the risk takers (especially with their own money) were the backbone of the UK. They flew from the first airline operations across the Channel in 1919.   If people had serious money in the 1930s and traveled internationally, they may well have flown on one of these large (130 foot wingspan) Handley Page bi-plane aircraft, which were the mainstay of British Imperial Airways at the time. They carried 26 passengers in first class only, in three d

LSO's and landing T Sparks

A long winded discussions on the role the LSO plays in landing on the carrier. After 900+ they have saved my bacon more than once. All the best, Tim The Lords of Landing "Right for lineup...don't go low...a little power...." At sea, the last word belongs to... by Peter Garrison The A-6E Intruder bomber thunders past the USS Abraham Lincoln's starboard side and rolls into a nearly vertical left bank. Condensation flickers above its swept wings like white fire; its airspeed bleeds rapidly from 300 knots to 150 under the drag of the five-G turn. In the cockpit, the inflatable G-suit snaps tightly around Lieutenant Brian Kasperbauer's legs. His eyes dart from the dancing blur of black instruments to the horizon beyond. Parallel to the aircraft carrier, Kasperbauer rolls level. Check speed, dirty up with gear and flaps, double-check tailhook down. Twice he lifts himself slightly from his se
