Airworthiness Directives; Airbus SAS Airplanes

Resumen

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