Is AD 2007-26-09 a recurring Airworthiness Directive?

Yes — AD 2007-26-09 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2007-26-09 apply to?

AD 2007-26-09 applies to Hartzell Propeller Inc. — models HC-Y. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Hartzell Propeller Inc. Compact Series Propellers

What this AD requires

The FAA is superseding an existing airworthiness directive (AD) for all Hartzell Propeller Inc. models ( )HC-( )( )Y( )-( )( )( ) compact series, constant speed or feathering propellers with Hartzell manufactured "Y" shank aluminum blades. That AD currently requires initial blade inspections, with no repetitive inspections; rework of all "Y" shank aluminum blades including cold rolling of the blade shank retention radius, blade replacement and modification of pitch change mechanisms for certain propeller models; and changing the airplane operating limitations with specific models of propellers installed. This AD requires the same actions but clarifies certain areas of the compliance, and updates a certain service bulletin (SB) reference to the most recent SB. This AD results from operators requesting clarification of certain portions of AD 2002-09-08. We are issuing this AD to prevent failure of the propeller blade from fatigue cracks in the blade shank radius, which can result in damage to the airplane and loss of airplane control.

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.

Whether AD 2007-26-09 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.
