Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Airbus Model A319, A320, and A321 series airplanes. This proposal would require a revision to the Airplane Flight Manual; inspection to detect damage of the wiring and adjacent structure along the length of the fairing of the fuel boost pump; corrective actions, if necessary; and modification of the fuel pump wire and fairing. This action is necessary to prevent electrical arcing of the fuel boost pump wire, which could result in wing structural damage, fire, and/or fuel vapor explosion. This action is intended to address the identified unsafe condition.
