What this AD requires

This document makes a correction to Airworthiness Directive (AD) 2006-23-02, which was published in the Federal Register on November 8, 2006 (71 FR 65390), and applies to certain Raytheon Aircraft Company (RAC) (formerly Beech) Models C90A, B200, B200C, B300, and B300C airplanes. AD 2006-23-02 requires you to inspect the flight controls for improper assembly or damage, and if any improperly assembled or damaged flight controls are found, take corrective action. We proposed in the notice of proposed rulemaking (NPRM) "unless already done" credit if the actions were already accomplished. However, we inadvertently left that language out of paragraph (e) of AD 2006-23-02. This document corrects that paragraph by inserting the phrase "unless already done."

Whether AD E6-21748 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 E6-21748 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.
