Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A320 and A321 series airplanes. This proposal would require replacement of the fuel pump strainers with improved strainers. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent blockage of fuel by the buildup of ice crystals, which could result in low fuel pressure, and consequent shutdown of the engine during critical phases of flight.
