What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace Model BAC 1-11 401/AK and 410/AQ airplanes, that requires replacement of certain landing gear brake accumulators with improved accumulators. The actions specified by this AD are intended to prevent loss of hydraulic pressure and possible structural damage to the airplane due to failure of the accumulator. This action is intended to address the identified unsafe condition.
