## Summary

We are revising an earlier proposed airworthiness directive (AD) for all Airbus Model A318 and A319 series airplanes, A320-211, - 212, -214, -231, -232, and -233 airplanes, and A321 series airplanes. The NPRM proposed to require an inspection to identify the part number and serial number of the main landing gear (MLG) sliding tubes installed on the airplane; and inspection of affected chromium plates for damage; an inspection of affected sliding tube axles for damage; and replacement of the sliding tube if necessary. The NPRM was prompted by a report of a rupture of a MLG sliding tube axle. This action revises the NPRM by removing certain service information that does not adequately address the identified unsafe condition and revising the compliance method. We are proposing this supplemental NPRM (SNPRM) to detect and correct cracks in the axle and (partial) detachment of the axle and wheel from the sliding tube, which could result in failure of an MLG. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
