Airworthiness Directives; British Aerospace (Jetstream) Model 4101 Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace (Jetstream) Model 4101 airplanes, that requires a one-time visual inspection of the conduit pipe for distortion or repairs, and replacement of the conduit pipe with a new pipe, if necessary. This amendment also requires replacement of the cable assemblies to the fuel standby pumps with new cable assemblies that have improved sheathing protection. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent electrical arcing due to damaged fuel standby pump cable assemblies and conduit pipes, which could create a possible ignition source, and consequent fire hazard.

Whether AD 99-25931 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 99-25931 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.
