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

What this AD requires

This amendment adopts a new airworthiness directive (AD), that is applicable to Hartzell Propeller Inc. model HC-B3TN-5( ) propellers, with blades part number (P/N) T10176H(B,K)-5 or T10178H(B)-11(R) that are installed on Mitsubishi Heavy Industries, Ltd, MU-2 series airplanes. This amendment requires replacement of those blades with blades of the latest design. This amendment is prompted by a report of in-flight propeller blade separation that caused a severe out-of- balance condition, damage to the airplane, and resulted in engine shutdown and a safe landing. The actions specified by this AD are intended to prevent propeller blade separation, damage to the airplane, and possible loss of the airplane.

Applies to Hartzell propeller blades addressed by Hartzell SB HC-SB-61-250, Revision 1, dated April 8, 2002 (blade separation prevention); specific propeller model designations are not present in the extracted applicability text.

Whether AD 2003-04-23 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 2003-04-23 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.
