Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A320-231 series airplanes. This proposal would require modification of the fire wall of each engine. This proposal is prompted by a report of a fire in the engine of an in-service airplane due to the fire wall being improperly sealed during production. The actions specified by the proposed AD are intended to prevent propagation of a fire through a gap (opening) in the fire wall in the event of an engine fire, as a result of improperly sealed fire wall.
