AD Pylones du B767

Bonjour !

Vu, sur un post de Jeannot, sur Anews (Crédit pour le sujet)
Le lien, retouvé parmi d'autres sur le sujet, vu que Anews les caviarde pour leur plus grande gloire (Pas de crédit pour le lien !)
Les pylones du 767, se criquent d'un manière assez préoccupante !
Juste lire l'article .... un peu inquiétant ... il manque des photos, mais au vu des réactions, c'est sérieux, faire des avions légers, c'est bien, mais cela inclus parfois des prises de risques !
Avis pour les "Tankers"

Structural cracks discovered recently on at least two American Airlines Boeing 767 jetliners, including one jet that air-safety regulators believe could easily have lost an engine, are prompting concerns that some of the problems may turn out to be more widespread.
Over the past two weeks, American, with oversight from the Federal Aviation Administration, has checked the bulk of its wide-body 767 fleet to look for possible cracks in critical components that attach engines to the wings. On Monday, the FAA said problems were found on three planes.

The agency said it was working with American and manufacturer Boeing Co. to “identify the source of the cracking” and was considering new industry-wide safety mandates. “We are considering additional action, including requiring more frequent inspections” of the suspect parts, called engine pylons, according to an FAA spokesman.

American spokesman Tim Wagner disputed the FAA’s tally of affected planes. He said the recent flurry of inspections found two planes with pylon-related cracks and the problems “were caught when they should have been.” He also said Monday that with metallurgical tests pending, “any speculation on the cause” of the cracks “isn’t based on science or technical findings.” Until the laboratory results are available, according to Mr. Wagner, definitive conclusions “would be a guess at best.”

Boeing, which has been working closely with the FAA to identify reasons for the cracks and assess their significance, didn’t have any immediate comment.

The size and type of some of the cracks discovered in the pylons surprised Boeing, which is now drafting a service bulletin that in the next few days is likely to recommend substantially stepped-up inspections by virtually all 767 operators, according to people familiar with the details. The FAA, which has authority to mandate the changes, is expected to adopt most of Boeing’s guidelines.

The issue is attracting high-level attention inside the FAA, Boeing and American partly because for years there have been relatively strict requirements to inspect certain parts of all 767 engine pylons after every 1,500 flights. Despite the frequent inspections, these people say, a routine check of one American jet for a different issue found a combination of cracks that hadn’t been seen before and was deemed by FAA officials to pose a significant hazard.
