## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A319-131, -132, and -133; A320-232 and -233; and A321-131 and -231 airplanes. This proposed AD would require inspecting for cracks or failure of the primary load path components of the engine forward mount, and corrective action if necessary. This proposed AD also would require removing, re-installing, and re-torquing the attachment bolts for the secondary load path. This proposed AD results from a report that, during modification of certain engine forward mount assemblies of the left and right engines done at an engine shop visit, an incorrect torque was applied to the attachment bolts. We are proposing this AD to prevent structural failure of the secondary load path of the forward engine mount, which, if combined with failure of the primary load path, could result in separation of the engine from the airplane.
