Airworthiness Directive · Amendment 39-9715 · Airbus Airplanes
Airbus Airplanes
This AD applies to Airbus A310-203, A310-221, A310-222, A310-304, A310-322, A310-324, A310-325.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A310 series airplanes, that requires repetitive inspections to detect discrepancies of the slat universal joint and steady bearing assemblies, and replacement of any discrepant assembly with a new, like assembly. This amendment also requires replacement of all slat universal joint and steady bearing assemblies with improved assemblies, which would terminate the repetitive inspections. This amendment is prompted by reports of broken or missing inner races on the slat universal joint and steady bearing assemblies of the slat transmission system. The actions specified by this AD are intended to prevent cracking of the inner race, which could cause it to break off and, consequently, allow the slat universal joint and steady bearing assemblies to become worn; this situation could result in failure of the shaft of the slat transmission system, and subsequent uncommanded movement of the associated slat.
