Airbus has identified a small area on A380 doors where a faulty door seal has been causing some big noise issues on what is a very quiet jet.
Sources said that it had ‘identified and understood the root cause’ of the problem, which achieved notoriety in January after a Singapore Airlines A380 made an emergency landing in Baku, Azerbaijan, after problems with a door seal led to oxygen masks being deployed.
The faulty seal area is to be fixed with a retrofit that can be done during planned maintenance schedules, according to a procedure for which Airbus is preparing to seek EASA approval.
The sources said the retrofit solution was expected to be EASA approved and ready in the near future.
In the meantime A380 users such as Qantas have been carrying out inspections to find any door seal issues before they ‘get noisy’, and have been told to expect the modification program to be rolled out in the shorter term.
So far several hundred A380 doors from both decks have been inspected, with less than 10 percent having been found to be faulty, a figure confirmed publicly by Airbus earlier this month.
