Airworthiness Directives; Hartzell Propeller Inc. Model HC-B3TN-5( )/T10282( ) Propellers

What this AD requires

The FAA is superseding an existing Priority Letter Airworthiness Directive (AD) for Hartzell Propeller Inc. model HC-B3TN- 5( )/T10282( ) propellers. That AD currently requires initial and repetitive inspections of the blade pilot tube bore area. This ad requires the same inspections. This AD results from a review of all currently effective ADs. That review determined that Priority Letter AD 88-24-15 was not published in the Federal Register to make it effective to all operators, as opposed to just the operators who received actual notice of the original Priority Letter AD. This AD also results from the discovery that the original AD omitted an airplane model with a certain Supplemental Type Certificate (STC) from the applicability. We are issuing this AD to prevent possible blade failure near the hub which can result in blade separation, engine separation, damage to the airplane, and possible loss of the airplane.

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

Which aircraft AD 2005-04-08 applies to

MakesHartzell Propeller Inc.
ModelsHC-B3TN-5()/T10282(), HC-B3TN

Applies to HC-B3TN-5()/T10282() propellers installed on Fairchild SA226-TC, SA226-AT, and SA226-T airplanes with Garrett TPE331-10UA-511G engines (per STCs SA344GL-D, SA4872SW, SA345GL-D), EXCLUDING propellers with blades P/N T10282N(), T10282NB(), T10282NK(), or T10282NE() installed.

Whether AD 2005-04-08 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 2005-04-08 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.
