## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A320-251N and A321-253N airplanes. This proposed AD was prompted by reports of cracks on the pylon block seals. This proposed AD would require replacement of the pylon block seals, as specified in a European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
