## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Airbus Industrie Model A300, A310, and A300-600 series airplanes, that would have superseded an existing AD that currently requires repetitive deployment tests of the ram air turbine (RAT) and checks of the adjustment of the locking rod. The proposed AD would also have required modification of the RAT, which would terminate the repetitive tests and checks. That proposal was prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. This new action would revise the proposed rule by expanding the applicability and by referencing revised procedures for accomplishment of the required actions. The actions specified by this new proposed AD are intended to ensure the availability of the RAT in case of need.
