FAA Issues Airworthiness Directive for Airbus A320 Family Planes, Oil Residue

FAA

The Federal Aviation Administration (FAA) has issued an Airworthiness Directive (AD) for ALL model Airbus A320-family planes regarding an issue with oil residue:

We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes.

This AD was prompted by reports of oil residue between the stator and the rotor parts of the position resolvers of the angle of attack (AOA) vane, which was a result of incorrect removal of the machining oil during the manufacturing process of the AOA resolvers.

This AD requires an inspection to determine if certain AOA probes are installed, and replacement of any affected AOA probe. We are issuing this AD to prevent erroneous AOA information and consequent delayed or non-activation of the AOA protection systems, which during flight at a high AOA, could result in reduced control of the airplane.

This AD becomes effective May 3, 2013.
