## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace BAe Model ATP airplanes, that requires repetitive inspections to detect corrosion of the brake hydraulic accumulators in the vicinity of the mounting straps; and corrective actions, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to detect and correct corrosion of the brake hydraulic accumulators, which could lead to loss of hydraulic pressure and consequent loss of braking capability of the airplane.
