Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A319 series airplanes, Model A320-211, -212, -214, -231, -232, and -233 airplanes, and Model A321 series airplanes that would supersede an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Following an automatic [additional center tank(s)] ACT fuel transfer failure on an A319, it was noted that the ACT manhole cover seals were extruded, allowing leakage.
This condition, if not corrected, can lead to fuel and/or vapour leakage, possibly resulting in a combustible fuel vapour/air mixture in the cargo compartment, which would constitute a fire risk.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
