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

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to all Mitsubishi Heavy Industries, Ltd. (Mitsubishi) MU-2B series airplanes. This AD requires modifying the airplanes' operating systems. This AD results from several icing-related incidents and accidents of MU-2B series airplanes, and the Federal Aviation Administration's investigation of the airplane design and pilot's ability to operate in icing conditions. The actions specified by this AD are intended to assist in preventing departure from controlled flight while operating in icing conditions.

applicability derived from the AD summary — confirm the model/serial from the records

Whether AD 00-11863 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 00-11863 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.
