Airworthiness Directives; AlliedSignal Inc. Model TFE731-40R-200G Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to AlliedSignal Inc. Model TFE731-40R-200G turbofan engines. This action requires replacing the fuel line between the main fuel pump and the motive flow pump with a serviceable assembly and adding a supporting bracket and clamp. This amendment is prompted by a report of a cracked fuel line between the main fuel pump and the motive flow pump causing the spraying of fuel on and around electrical components. The actions specified in this AD are intended to prevent fuel spraying on and around electrical components due to a cracked fuel line, which could result in an engine fire.

Part-conditional — 3061191-1.

Whether AD 98-10-15 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.

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.
