Is AD 2010-10-17 a recurring Airworthiness Directive?

No — AD 2010-10-17 is a one-time directive. Verify it was complied with in the aircraft's records.

Airworthiness Directives; Mitsubishi Heavy Industries, Ltd. Various Models MU-2B Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) to supersede Airworthiness Directive (AD) 2006-17-01, AD 2006-15-07, AD 2000-02-25, and AD 97-25-02, which applies to certain Mitsubishi Heavy Industries, Ltd. (MHI) various Models MU-2B airplanes. An FAA MU-2B safety evaluation resulted in the standardization of the MU-2B specific training and the FAA-accepted pilot operating checklists through a special Federal aviation regulation (SFAR). MHI revised the airplane flight manuals (AFMs) to align them with the information in that training and the checklists. In addition, incorporating all AFM revisions up to and including this latest AFM revision will incorporate all AFM compliance actions required by the four above-mentioned ADs. This AD would retain from AD 2006-17-01 the inspection of the engine torque indication system and possible recalibration of the torque pressure transducers and would require incorporating all revisions up to and including the latest revisions of the AFM. We are issuing this AD to correct inconsistencies in critical operating procedures between the MU-2B specific training, the FAA-accepted pilot operating checklists, and the AFMs, which, if not corrected, could result in the pilot inadvertently taking inappropriate actions in critical operating conditions.

ModelsMU-2B-25, MU-2B-26, MU-2B-26A, MU-2B-36A, MU-2B-40, MU-2B-60, MU-2B-35, MU-2B-36, MU-2B, MU-2B-10, MU-2B-15, MU-2B-20, MU-2B-30

Applies to all serial numbers of the listed MU-2B family models under TCDS A10SW and TCDS A2PC (no serial numbers exist for MU-2B-35/-36 under A10SW). Concerns AFM/checklist procedural inconsistencies, not a hardware modification.

Whether AD 2010-10-17 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 2010-10-17 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.
