Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A319-115, A319-132, A320-214, A320-232, A321-211, A321-213, and A321-231 airplanes. This proposed AD was prompted by a report of certain tie rod assemblies installed on the hinged fairing assembly of the main landing gear (MLG) with no cadmium plating on the rod end threads. This proposed AD would require a detailed inspection of certain tie rod assemblies installed on the hinged fairing assembly of the MLG for the presence of cadmium plating, and replacement of tie rod assemblies without cadmium plating. We are proposing this AD to detect and correct the absence of cadmium plating on the rod end threads of the tie rod assemblies. The absence of cadmium plating could lead to galvanic corrosion of the tie rod end threads, resulting in rod end failure, loss of a MLG door, and consequent damage to the airplane.

The agency’s own summary, as published.
