Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A319-131, A319-132, A319-133, A320-231, A320-232, A320-233, A321-131, A321-231, and A321-232 airplanes. This proposed AD was prompted by reports of fan cowl door (FCD) losses during take-off. This proposed AD would require modification and re-identification, or replacement, of certain FCDs, and installation of a placard in the flight deck. We are proposing this AD to address the unsafe condition on these products.
