Airworthiness Directive 2009-22-03
recurringAirworthiness Directives; Hartzell Propeller Inc. ()HC-()2Y(K,R)-() Series Propellers
What this AD requires
The FAA is superseding an existing airworthiness directive (AD) for Hartzell Propeller Inc. ()HC-()2Y()-() series propellers with non-suffix serial number (SN) propeller hubs installed on Lycoming O-, IO-, LO-, and AEIO-360 series reciprocating engines. That AD currently requires initial and repetitive eddy current inspections (ECIs) of the front cylinder half of the propeller hub for cracks and removing cracked hubs from service before further flight. In addition, that AD allows installation of an improved design propeller hub (suffix SN "A" or "B") as terminating action to the repetitive ECI. This ad requires the same actions but changes the affected propeller series designation to ()HC-()2Y(K,R)-() series propellers with non-suffix SN propeller hubs and suffix SN letter "E" propeller hubs. This AD also expands the engine eligibility to include Lycoming LIO-, TO-, LTO-, AIO-, and TIO-360-series engines. This AD results from the need to make changes to the affected series designation of propellers, to expand the engine applicability, and to respond to comments received on AD 2006- 18-15. We are issuing this AD to prevent failure of the propeller hub causing blade separation and subsequent loss of airplane control.
Which aircraft AD 2009-22-03 applies to
Applies to ( )HC-( )2Y(K,R)-( ) series propellers with non-suffix serial number (SN) propeller hubs and hubs with suffix SN letter 'E', installed on Lycoming O-, IO-, LO-, LIO-, TO-, LTO-, AIO-, AEIO-, and TIO-360 series reciprocating engines. Installed on, but not limited to, numerous airplane types listed in the AD's applicability table (e.g., Piper Comanche PA-24, Mooney M-20 series, Cessna Cardinal 177, Beech Duchess 76, Piper Seminole PA-44, Aviat Husky, and others); source table truncated.
Whether AD 2009-22-03 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:
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.
