Airworthiness Directives; Hartzell 

Propeller Inc. Compact Series 

Propellers 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: 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. 

DATES: This AD becomes effective 

January 30, 2008. The Director of the 

Federal Register previously approved 

the incorporation by reference of certain 

publications listed in the regulations as 

of June 13, 2002 (67 FR 31113, May 9, 

2002). The Director of the Federal 

Register approved the incorporation by 

reference of certain publications listed 

in the regulations as of January 30, 2008.

information identified in this AD from

Publications Department, One Propeller

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 by 

superseding AD 2002–09–08, 

Amendment 39–12741 (67 FR 31113, 

May 9, 2002) with a proposed AD. The 

proposed AD applies to Hartzell 

Propeller Inc. models ( )HC–( )( )Y 

( )–( )( )( ) compact series, 

constant speed or feathering propellers 

with Hartzell manufactured ‘‘Y’’ shank 

aluminum blades. We published the 

proposed AD in the Federal Register on 

August 14, 2006 (71 FR 46413). That 

action proposed to require the same 

actions as AD 2002–09–08, but would 

clarify certain areas of the compliance 

and would update a certain SB reference 

to the most recent SB. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comment received. 

Incorporate Service Documents by 

Reference and Publish Them in the 

Document Management System 

The Modification and Replacement 

Parts Association requests that all 

service documents deemed essential to 

the accomplishment of the AD be 

incorporated by reference into the 

regulatory instrument, and published in 

the Docket Management System. We 

partially agree. We have incorporated 

pertinent service material into the 

regulatory section of this AD. However, 

at this time, the FAA does not post 

service material on the Federal Docket 

Management System. We are in the 

process of reviewing issues surrounding 

the posting of service bulletins on the 

Federal Docket Management System as 

part of an AD docket. Once we have 

thoroughly examined all aspects of this 

issue and have made a final 

determination, we will consider 

whether our current practice needs to be 

revised. 

Format Changes 

We changed the propeller blade shank 

cold rolling information from being a 

note, to paragraphs. We also added 

paragraphs to the alternative methods of 

compliance, to make the information 

more readable. 

Conclusion 

We have carefully reviewed the 

available data, including the comment 

received, and determined that air safety 

and the public interest require adopting 

the AD with the changes described 

previously. 

Costs of Compliance 

We estimate that this AD will affect 

35,750 propellers installed on airplanes 

of U.S. registry. We expect this AD will 

cost about $700 per propeller. Total cost 

to U.S. operators for this AD would be 

about $25.025 million. However, we 

also expect that all of the affected 

propellers should have already been 

inspected to comply with the existing 

AD’s requirements to inspect, and 

mstockstill on PROD1PC66 with RULES
