Is AD 2002-01-23 a recurring Airworthiness Directive?

Yes — AD 2002-01-23 requires a repetitive inspection every 200 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2002-01-23 apply to?

AD 2002-01-23 applies to Raytheon. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Raytheon Model Beech 400, 400A, and 400T series airplanes; Model Beech MU-300-10 airplanes; and Model Mitsubishi MU-300 airplanes. This action requires repetitive inspections to detect cracking in the radius of the cutout of the aft flange of the left engine forward carry-through mount bracket, and replacement with a new bracket and fitting if necessary. This action is necessary to prevent failure of the engine mount and possible loss of the engine, and consequent loss of control of the airplane. This action is intended to address the identified unsafe condition.

Repetitive inspection. Re-inspect every 200 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

MakesRaytheon

Addresses cracking in the radius of the cutout of the aft flange of the left engine forward carry-through mount bracket, to prevent failure of the engine mount and loss of the engine. Compliance via Raytheon Safety Communique No. 189, Revision 1, dated January 2002, and Raytheon Maintenance Manual Chapter 54-40-00. The full aircraft model/serial applicability list ("preceding applicability provision") is not present in this excerpt.

Whether AD 2002-01-23 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 2002-01-23 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.
