Problemi ai fastener del 787 collegamento ala-fusoliera

Messaggio da flyforever85 »

questo è l'inizio dell'articolo:
While removing and reapplying sealant to each 787 remains critical in preparing for delivery, the workmanship of its application is not the only item Boeing has identified for change inside the aircraft's composite wings; a design change discovered in the fall of 2009 requires the removal and replacement of thousands of improperly coated fastener joints to ensure the majority-composite jetliner's protection from lightning strikes.
altro punto saliente
[...] In fact, ZA001, Boeing's lead 787 test aircraft suffered a lightning strike in May 2010, with no trace of damage to the aircraft beyond instrumentation inside the right wing where the bolt was believe to have hit.

The issue was first discovered in fall 2009, when barely a handful of production 787s had entered final assembly. Boeing has continued deliveries to final assembly, pausing several times in 2010 to allow shipsets to arrive at a higher level of assembly completion, but opted to push the wing fastener joint rework to change incorporation after assembly, though wings with this design issue continue to arrive in Everett from Japan.
