Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A320-232 and -233 series airplanes. This proposal would require replacement of the fuel metering units (FMU) of each engine with new FMU's. 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 an inadvertent increase in thrust, which could result in reduced controllability of the airplane during final approach.
