This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A310 and A300-600 series airplanes. This amendment requires repetitive inspections to detect distortion and/or cracks on the attachment brackets of the backrest recline control locks of certain seats. It also provides for an optional modification which, if accomplished, terminates the repetitive inspections. This amendment is prompted by a report of failure of the bracket of the backrest recline control lock on a seat due to fatigue-related cracking. The actions specified by this AD are intended to prevent fatigue-related cracking and/or distortion, which could result in failure of the seat backrest attach fitting, and the subsequent uncommanded 50 angle recline of the pilot or co-pilot seat; this situation could lead to the temporary inability of the pilots to control the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
