Is AD 97-18-02 a recurring Airworthiness Directive?

Yes — AD 97-18-02 requires a repetitive inspection every 400 hours or 60 months. Next-due depends on the aircraft's time in service.

Which aircraft does AD 97-18-02 apply to?

AD 97-18-02 applies to Hartzell Propeller Inc. — models HA-A2V20-1B, 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 supersedes four existing airworthiness directives (ADs), applicable to Hartzell Propeller Inc. ( )HC-( )(2,3)(X,V)( )-( ) series propellers with aluminum blades, that currently require inspections for cracks in blade shanks and clamps. This amendment 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, this AD 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, this AD requires an additional initial and repetitive visual and magnetic particle inspection of the hub and, if necessary, replacement with serviceable parts. This amendment is prompted by reports of cracked blades, blade clamps, and hubs and reports of blade separations. 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 400 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.

ModelsHA-A2V20-1B, HC, HA

Applies to Hartzell hub models (_)HC-(_)(2,3)(X,V)(_)-(_) series and HA-A2V20-1B series propellers with aluminum blades, installed on but not limited to a long multi-manufacturer list of legacy piston aircraft (Aero Commander, Beech, Bellanca, Cessna, Piper, Mooney, Navion, Piaggio, Pilatus, Stinson, and many others per the AD's aircraft table); list is explicitly non-exhaustive per the AD's Note 1. Compliance paragraph (b) covers hub models (_)HC-(A,D)(2,3)(X,V)(_)-(_) and HA-A2V20-1B, excluding hub model HC-A3VF-7(_).

Whether AD 97-18-02 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.
