Airworthiness Directives; General Machine-Diecron, Inc. Actuator Nut Assembly for the Right Main Landing Gear Installed on Certain Raytheon Aircraft Company (Formerly Beech) Airplanes

What this AD requires

The FAA adopts a new airworthiness directive (AD) for General Machine--Diecron, Inc. (GMD) actuator nut assembly, part number (P/N) GMD115-810029-17 and P/N GMD115-810029-23, that are installed on certain Raytheon Aircraft Company (Raytheon) (formerly Beech) airplanes that are not equipped with a hydraulic main landing gear (MLG) or modified to a hydraulic MLG. This AD requires you to determine by maintenance records check and/or inspection whether any actuator nut assembly, P/N GMD115-810029-17 or P/N GMD115-810029-23, is installed on the right main MLG actuator, and, if installed, requires you to replace it with a new actuator nut assembly, P/N GMD115-810029-23B or FAA- approved equivalent P/N. This AD results from several reports of failures of the actuator nut assembly, P/N GMD115-810029-17 and P/N GMD115-810029-23. We are issuing this AD to prevent failure of the actuator nut assembly for the right MLG actuator, which could result in failure of the MLG. This failure could prevent the extension or retraction of the MLG.

Applies to the listed right main landing gear (MLG) actuator nut assembly part numbers installed on Raytheon (formerly Beech) airplanes not equipped with, and not modified to, a hydraulic MLG. Model list is introduced as 'not limited to' (non-exhaustive). Several models exclude aircraft incorporating specific Beech kits (e.g., 90-8011, 99-8010-1, 101-8018) or factory-installed hydraulic landing gear.

Whether AD 2006-12-25 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2006-12-25 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.
