Federal Aviation Administration December 18, 2013 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318-111 and -112 airplanes, Model A319-111, -112, -113, - 114, and -115 airplanes, Model A320-111, -211, -212, and -214 airplanes, and Model A321-111, -112, -211, -212, and -213 airplanes. This proposed AD was prompted by reports of broken aft engine mount retainers. This proposed AD would require inspecting the aft engine mount retainers for surface finish, and for cracks and failure, and replacement if necessary. We are proposing this AD to prevent failure of retainer brackets of the aft engine mount and consequent loss of the locking feature of the nuts of the inner and outer pins. Loss of the pins will result in the aft mount engine link no longer being secured to the aft engine mount.
