Unsafe Condition
Cracking of the hardened steel inner race, and broken or missing inner races of the steady bearing assemblies of the flap transmission system could cause failure of the steady bearing shafts during a subsequent asymmetric stop, leading to uncommanded asymmetric retraction of the flap and reduced controllability of the airplane.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Perform a visual inspection to detect damage or discrepancies of the steady bearing assemblies per Airbus Service Bulletin A310-27-2067, Revision 1. If damage or discrepancies are found with groove depth less than 1 mm, replace the assembly within 50 landings. If groove depth is 1 mm or more, replace immediately prior to further flight. Replace all assemblies with improved versions within 5 years after the AD's effective date per Airbus Service Bulletin A310-27-2074.

Compliance Time
Prior to the accumulation of 2,000 total landings or within 500 flight hours after the effective date of this AD, whichever occurs later. For replacements due to discrepancies: within 50 landings or prior to further flight as specified. The improved assembly replacement must be done within 5 years after the effective date.
