Airworthiness Directives; Airbus Model A300 Airplanes; Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310 Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all of the airplanes identified above, that requires revising the FAA-approved maintenance program to include a new airplane maintenance manual task that specifies a detailed inspection after each ram air turbine (RAT) retraction. This AD also requires, for certain airplanes, a one-time inspection to detect breaks in the bottom flange fitting of the RAT and corrective actions, if necessary; for certain airplanes, an adjustment of the ejection jack; and, for certain other airplanes, replacement of the aluminum part with an improved steel part. The actions specified by this AD are intended to prevent failure of the RAT yoke fitting, which could result in the loss of RAT function and possible loss of critical flight control in the event of certain emergency situations. This action is intended to address the identified unsafe condition.
