Airworthiness Directive · Amendment 39-9188 · Airbus SAS Airplanes
Airbus SAS Airplanes
This AD applies to Airbus SAS BAC 1-11 200 Series, BAC 1-11 400 Series.
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 all British Aerospace Model BAC 1-11-200 and -400 series airplanes, that requires inspections of the bearings of the aileron control system, and correction of discrepancies. This amendment is prompted by a report indicating that an operator experienced difficulties wherein considerable pressure was required to manually input roll control due to seized bearings in the aileron control system. The actions specified by this AD are intended to prevent such seizure of bearings, which could reduce the pilot's ability to initiate roll control during critical phases of flight.
