Airworthiness Directives; Learjet Model 31 and 35A Airplanes

What this AD requires

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Learjet Model 31 and 35A airplanes, that currently requires replacement of two segments of 16 American Wire Gauge (AWG) wire with 8 AWG wire at the connector that is connected to the auxiliary cabin heater relay box. That AD was prompted by a report indicating that two segments of the 16 AWG wire in the auxiliary cabin heater, which were spliced during production, do not provide adequate current-carrying capacity. This amendment requires the installation of a new replacement wire assembly. The actions specified by this AD are intended to prevent electrical arcing and consequent fire hazard that could result from wiring with inadequate current-carrying capacity.

Whether AD 98-6950 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 98-6950 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.
