Singapore Airlines and Qantas Airways said on Friday they discovered cracks on the wing ribs of some of their Airbus A380s, but said the cracks pose no threat to safety and repairs have been carried out.

The remarks came after Airbus said on Thursday that engineers discovered minor cracks in the wings of a "limited number" of A380s, but said the cracks were not affecting the safety of the aircraft.

"Cracks were found on a small number of wing rib feet on an Airbus A380 during inspections in the second half of last year. These pose no safety issue and repairs were carried out on the aircraft," SIA's spokesman Nicholas Ionides said in an email to reporters.

"Repairs were subsequently carried out on a second aircraft. We have kept the relevant regulatory authorities fully informed and will be carrying out inspections and any necessary repairs on other A380s as they go in for routine checks," he added.

Qantas separately said that "minuscule cracking" was found in the wing ribs of the Qantas A380 being repaired in Singapore after one of its Rolls-Royce Trent 900 engines suffered a mid-air blowout in 2010.

"Investigations have found that the cracking is unrelated to the engine failure incident experienced by this aircraft in November 2010 and is not unique to Qantas. It has now been repaired," the carrier said in a statement.

"No immediate action is required by A380 operators because the cracking presents no risk whatsoever to flight safety," Qantas said.

Airbus said it has traced the origin of the problem and developed an inspection and repair procedure that will be done during routine, scheduled four-year maintenance checks.

Singapore Air operates 14 A380s and has five on order, while Qantas has taken delivery of 10 of its 20 A380 aircraft on order, according to the airline's website.

di "piccole fratture sull'ala" io non ne ho mai sentito parlare nei vari thread né su altri siti. può succede "normalmente"?

tornando sul thread, che mi dicano "cracks in the wing of a limited number of A380s" a me inquieta quel "limited number", cioè già che fosse uno sarebbe tanto, se mi dici che è successo su più modelli mi dai da speculare sul discorso e immaginare allegramente che possa succedere ancora etc. etc.
 
C e' da star tranquilli che le ispezioni abbiano portato alla luce questo problema. Certo, io su macchine di 3 anni e 10 mesi un po' di strizza a volare l avrei...
Battute a parte, mi inquieta la dichiarazione di Airbus.
Faccio un check pre volo, noto le crepe, e rilascio la macchina con 500 persone sopra, abile fino al tagliando dei 4 anni?
Mi sembra un po' azzardato..
Rick........??????
 
Innanzi tutto bisogna vedere che tipo di crepe ci sono, piccole fessurazioni di pochi millimetri o addirittura decimi di millimetro quasi impercettibili. Non credo si parli di una spaccatura di un'ala altrimenti sai il disastro a livello di immagine che provocherebbe ad Airbus. Ad ogni modo pensano ci vadano molto cauti a distribuire certe notizie, specialmente in un momento cosi nero dell'economia mondiale...
 
Cracks have been found on the wing ribs of at least three Airbus A380s belonging to Singapore Airlines and Qantas Airways.

Both carriers said the cracks were discovered in the second quarter of 2011, and that they have been repaired and posed no danger to flight safety.

The carriers' comments come a day after Airbus said "very small cracks" have been found on some "non-critical wing rib-skin attachments on a limited number of A380 aircraft".

Singapore Airlines said the cracks were first discovered during an A380 inspection last year.

"These pose no safety issue and repairs were carried out on the aircraft. Repairs were subsequently carried out on a second aircraft," said an SIA spokesman.

He added that the relevant authorities have been informed and checks and repairs will be done on other A380s as the aircraft undergo routine C checks. Both affected aircraft are back in operation.

Qantas meanwhile said that "minuscule cracking" was found on the wing ribs of the A380 that suffered an uncontained engine failure in November 2010. This aircraft is still in Singapore, where it made an emergency landing after the incident, and Qantas hopes it will return to service in March.

"Investigations have found that the cracking is unrelated to the engine failure incident experienced by this aircraft in November 2010 and is not unique to Qantas. It has now been repaired," said a Qantas Spokesman.

Airbus said that it has since developed an inspection and repair procedure which will be done during routine, scheduled four year maintenance checks for the A380s. It has informed all A380 operators and the European airworthiness authority is aware of the issue and has accepeted its recovery approach, said a spokesman.

"This is not a safety issue and aircraft performance is not affected. Any fix, if necessary, can be done during regular maintenance," Airbus added.

loro non dicono "è normale ci siano delle microfratture", dicono solo "non è niente di grave". se mi avessero detto la prima frase, posso anche pensare che loro lo sappiano meglio di me e quindi non ci sia da preoccuparti, se peró mi dici la seconda opzione, io non rimango cosí tranquillo e gradirei avere maggiori dati prima di mettere piede su un A380!
 
gli inglesi son usciti da airbus proprio per il 380 , facile che alla primo problema, che potrebbe non essere una stupidaggine, si alzino i megafoni come per le subforniture delle palette di RR. Mah vediamo cosa vien fuori dll'indagine interna.

intanto:
 
A380 Wing Cracks Not Affecting Operations

Jan 6, 2012

LONDON

Airbus says it has already developed a fix to wing cracking found on some Airbus A380s.

The cracks, first reported by the Sydney Morning Herald, have been seen by at least Qantas and Singapore Airlines. The cracks were first found on the Qantas A380 that suffered an uncontained engine failure with one of its four Trent 900 engines two years ago.

Airbus confirms the cracking on “some non-critical wing rib-skin attachments on a limited number of A380 aircraft.” The aircraft maker adds that safe operations of the fleet are not affected and no flight limitations are being put on the A380.

Airbus says a inspection and repair process has been identified, although it would not detail how the fix is made. The repair is being done as part of four-year maintenance checks, it adds.

The approach has been validated by the European Aviation Safety Agency, Airbus says.
