Airworthiness Directives; Raytheon (Beech) Model 400A and 400T Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon (Beech) Model 400A and 400T series airplanes, that requires replacement of temperature switch assemblies of the wing ice protection system with new, improved parts. This amendment is prompted by reports of electrical continuity problems with solder joints on the temperature switches of the wing ice protection system. The actions specified by this AD are intended to prevent detachment or breakage of wires in the temperature switch assemblies of the wing ice protection system. Such detachment or breakage of wires could result in the flightcrew not being advised of an over-temperature situation on the leading edge of the wing, which could result in structural damage to the wing.

Which aircraft AD 2000-09-12 applies to

MakesRaytheon

Replace wing ice-protection system temperature switch assemblies per Raytheon Service Bulletin 30-3008 Rev 1 (Aug 1999); replacements already done per the original SB (Mar 1999) are credited; installation of old-part-number switch assemblies prohibited thereafter.

Whether AD 2000-09-12 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 2000-09-12 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.
