Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A318 series airplanes; Model A319 series airplanes; Model A320 series airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -252N, -253N, -271N, -272N, - 251NX, -252NX, -253NX, -271NX, and -272NX airplanes. This proposed AD was prompted by reports of a certain nose landing gear (NLG) sliding tube having widespread overheat damage and multiple cracks on the base metal during shop visits. This proposed AD would require a special detailed inspection (SDI) of the affected NLG sliding tube and replacement, as applicable. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
