Airworthiness Directives; Pratt & Whitney JT8D Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to Pratt & Whitney (PW) JT8D series turbofan engines, that requires inspections of main fuel pump control shafts for excessive spline wear. Additionally, as terminating action to the inspections, this action requires the replacement of the main fuel pump control shaft with parts of improved design, and reworking the main fuel pump impeller, impeller gear train plate assembly, and impeller cover assembly. This amendment is prompted by reports of failed main fuel pump control shafts caused by excessive spline wear. The actions specified by this AD are intended to prevent loss of engine throttle control, uncommanded acceleration, uncommanded deceleration or inflight shutdown, which could result in reduced airplane control during a critical phase of flight.

Whether AD 2000-22-06 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 compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2000-22-06 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.
