Airworthiness Directives; Pratt & Whitney JT9D-7R4 Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to Pratt & Whitney (PW) JT9D-7R4 series turbofan engines. This amendment requires on JT9D-7R4 series turbofan engines with steel fan cases, replacement of the existing one-piece fan case shield with a thicker four-piece fan case shield and would add four fan case shield supports. This amendment results from two uncontained full fan blade fracture events that resulted in penetration of the steel fan case and fan case shield. We are issuing this AD to prevent uncontained fan blade failures, resulting in damage to the airplane.

Part-conditional — 802095, 802094.

Applies to engines with steel fan cases: JT9D-7R4D/-7R4D1/-7R4E/-7R4E1/-7R4E4/-7R4H1 engines with PW SB 72-312 incorporated require replacing fan case shield P/N 802095; JT9D-7R4G2 engines with PW SB 72-88 and SB 72-311 incorporated, or with SB 72-311 but not SB 72-88 incorporated, require replacing fan case shield P/N 802094. The initial applicability sentence references a preceding provision not captured in this excerpt.

Whether AD 2004-01-08 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 2004-01-08 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.
