Hopefully, the company culture at Airbus is different to Boeing, and solution found to the fuel tank issue will be one that prioritises safety rather than cost cutting and bonuses.
Oversight from EASA will likely be a lot better than FAA’s hands off approach with Boeing.
Airbus have done well with the basic A320 design but at 30+ years old, it’s getting a bit dated, particularly in the flight deck. Time to start thinking about a new clean sheet design which integrates all the technological advances made since the 1980s. The current design can easily see out this decade, but by then Boeing will be coming out with a long overdue B737 replacement which will likely be superior to the NEO.
