Cracks have been found on Airbus A380 wings by Singapore Airlines and Qantas.
The cracks occurred on the wing ribs of their Airbus A380s. Qantas discovered the problem while repairing a Royce Trent 900 engines blowout in 2010.
Airbus says they know the origin and have developed an inspection and repair procedure for scheduled four-year maintenance checks.
The problem has been found on at least five planes.
The Australian Licensed Aircraft Engineers Association says Airbus A380s should be grounded, that flying with them is gambling with people’s lives, that it is risky to wait for a 4 year maintenance check. Airbus counters that the cracks are “on non-critical wing attachments” and pose no threat.
