Airworthiness Directives; Pratt and Whitney Model JT8D-9A Turbofan Engines

What this AD requires

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.

Applies only to the specific engines identified by serial number; installed on but not limited to Boeing 727/737 and McDonnell Douglas DC-9 series aircraft.

Whether AD 95-15-51 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 95-15-51 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
