## Abstract

This document publishes in theFederal Register an amendment adopting Airworthiness Directive (AD) T95-15-51 that was sent previously to all known U.S. owners and operators of Pratt and Whitney (PW) Model JT8D-9A engines by individual telegrams. This AD requires inspection, and replacement, if necessary, of suspect 7th through 12th stage HPC disks. This amendment is prompted by a report of an uncontained engine failure during takeoff. The actions specified by this AD are intended to prevent an uncontained HPC disk failure and damage to the aircraft.
