Airworthiness Directives; Raytheon Aircraft Company Models B300 and B300C Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Models B300 and B300C airplanes (commonly referred to as Beech Models B300 and B300C airplanes). This AD requires modifying the elevator trim tab actuators by incorporating a new elevator trim tab actuator assembly kit, replacing the elevator trim tab pushrod assembly, or modifying the elevator spar opening, whichever is applicable. Reports from operators of ice forming on the elevator trim tab actuators and jamming the trim tab control prompted this action. The actions specified by this AD are intended to prevent jamming of the elevator trim tab actuator caused by ice formations, which could result in loss of control of the airplane.

Whether AD 99-1446 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 99-1446 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.
