Is AD 03-15991 a recurring Airworthiness Directive?

Yes — AD 03-15991 requires a repetitive inspection every 500 hours or 60 months. Next-due depends on the aircraft's time in service.

Which aircraft does AD 03-15991 apply to?

AD 03-15991 applies to Hartzell — models HC, HA. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Hartzell Propeller Inc. ( )HC-( )(2,3)(X,V)( )-( ) Series and HA-A2V20-1B Series Propellers with Aluminum Blades

What this AD requires

This amendment revises an existing airworthiness directive (AD), that is applicable to Hartzell Propeller Inc. ( )HC-( )(2,3)(X,V)( )-( ) series and HA-A2V20-1B series propellers with aluminum blades. That AD currently requires initial and repetitive dye penetrant and eddy current inspections of the blade and an optical comparator inspection of the blade retention area, and, if necessary, replacement with serviceable parts. In addition, that AD currently requires initial and repetitive visual and magnetic particle inspection of the blade clamp, dye penetrant inspection of the blade internal bearing bore, and, if necessary, replacement with serviceable parts. Also, for all HC-(1,4,5,8)(2,3)(X,V)( )-( ) steel hub propellers, that AD currently requires an additional initial and repetitive visual and magnetic particle inspection of the hub, and, if necessary, replacement with serviceable parts. This amendment revises that AD by permitting the replacement of affected propellers with Hartzell Propeller Inc. model "MV" series propellers as an optional terminating action for the initial and repetitive inspections of that AD. This amendment is prompted by type certification approval of the Hartzell "MV" series propellers that are direct replacements for the affected propellers, and service bulletin approval to allow modification of affected propellers to the "MV" type design configuration. The actions specified by this AD are intended to prevent blade separation due to cracked blades, hubs, or blade clamps, which can result in loss of control of the airplane.

Repetitive inspection. Re-inspect every 500 hours or 60 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

ModelsHC, HA

Applies to Hartzell propeller hub models denoted by the pattern ( )HC-(1,4,5,8)(2,3)(X,V)( )-( ) per paragraph (a), and ( )HC-(A,D)(2,3)(X,V)( )-( ) and HA-A2V20-1B (except HC-A3VF-7( )) per paragraph (b); inspection/compliance intervals vary by TSN/TIS thresholds relative to the September 11, 1997 effective date per Hartzell SB HC-SB-61-217 Rev 1.

Whether AD 03-15991 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.

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.
