## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 727, 737-100, 737-200, and 737-200C series airplanes, that requires one-time inspections to determine the part numbers of hydraulic accumulators installed in various areas of the airplane, and follow-on corrective actions if necessary. The actions specified by this AD are intended to prevent high-velocity separation of a barrel, piston, or end cap from a hydraulic accumulator. Such separation could result in injury to personnel in the accumulator area; loss of cabin pressurization; loss of affected hydraulic systems; or damage to plumbing, electrical installations, or structural members. This action is intended to address the identified unsafe condition.
