## Summary

This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes, that currently requires an inspection of the parking brake operated valve (PBOV) of the main landing gear to identify the part and serial numbers, and follow-on actions if necessary. That AD also provides for optional terminating action for the requirements of the AD. This action would require accomplishment of the previously optional terminating action. The actions specified by the proposed AD are intended to prevent leakage of the PBOV and consequent failure of the "blue" hydraulic system and alternate parking brake and emergency braking systems, which could affect elements of the hydraulics for flaps, stabilizer, certain spoilers, elevator, rudder, and aileron. This action is intended to address the identified unsafe condition.
