## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all British Aerospace Model BAC 1- 11 401/AK and 410/AQ airplanes. This proposal would require replacement of certain landing gear brake accumulators with improved accumulators. This action is necessary 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.
