14 CFR Part 39
[Docket No. FAA-2007-28876; Directorate Identifier 2000-NE-08-AD;
Amendment 39-15311; AD 2007-26-09]
RIN 2120-AA64
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.

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
[[Page 72916]]
rework or replace the aluminum blades. Therefore, we expect that this
AD will have no additional cost.
Docket Number Change
We are transferring the docket for this AD to the Federal Docket
Management System as part of our on-going docket management
consolidation efforts. The new Docket No. is FAA-2007-28876. The old
Docket No. became the Directorate Identifier, which is 2000-NE-08-AD.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will not have a
substantial direct effect on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
We prepared a summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary at the
address listed under ADDRESSES.

(d) The parentheses appearing in the propeller model number
indicates the presence or absence of an additional letter(s) that
varies the basic propeller model. This AD applies regardless of
whether these letters are present or absent in the propeller model
designation.
Unsafe Condition
(e) 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 aluminum
blade shank radius, which can result in damage to the airplane and
loss of airplane control.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified unless the
actions have already been done.
(g) If the propeller maintenance records show compliance with AD
77-12-06R2, then compliance was previously done and no further
action is required.
(h) Propellers are considered in compliance with the one-time
inspection and rework requirements only, of this AD if:
(1) All blades are serial number D47534 and above, or
(2) All blades are identified with the letters ``PR'' or ``R''
which are ink-stamped on the camber side, or the letters ``RD''
which are metal-stamped on the blade butt.
Models ( )HC-( )( )Y( ) Compact Series ``Y'' Shank Propellers
(i) If propeller models ( )HC-( )( )Y( ) have not been inspected
and reworked in accordance with AD 77-12-06R2, then before further
flight, do a one-time action to remove, inspect, rework, or replace
blades if
[[Page 72917]]
necessary using Hartzell Service Bulletin (SB) No. 118A, dated
February 15, 1977.
Propeller Blade Shank Cold Rolling
(j) One requirement in Hartzell SB No. 118A is the cold rolling
of the propeller blade shank.
(1) Cold rolling is a critical requirement in the prevention of
cracks in the blade. Propeller repair shops must obtain and maintain
proper certification to perform the cold rolling procedure.
(2) For a current list of propeller overhaul facilities approved
to perform the blade shank cold rolling procedure, contact Hartzell
Product Support, telephone (937) 778-4200.
(3) Not all propeller repair facilities have the equipment to
properly perform a cold roll of the blade shanks.
(4) In addition, any rework in the blade shank area will also
necessitate the cold rolling of the blade shank area, apart from the
one-time cold rolling requirement of this AD.
Instrument Panel Modifications
(k) If airplanes with propeller models ( )HC-C2YK-( )( )( )/( )(
)7666A-( ), installed on (undampered) 200 or more horsepower
Lycoming IO-360 series engines, have not been modified using AD 77-
12-06R2, then modify the airplane instrument panel according to the
following subparagraphs before further flight. Airplanes include,
but are not limited to, Mooney M20E and M20F (normal category),
Piper PA-28R-200 (normal category), and Pitts S-1T and S-2A
(acrobatic category).
(1) For normal category airplanes, before further flight, remove
the present vibration placard and affix a new placard near the
engine tachometer that states:
``Avoid continuous operation:
Between 2,000 and 2,350 rpm.''
(2) For utility and acrobatic category airplanes, before further
flight, remove the present vibration placard and affix a new placard
near the engine tachometer that states:
``Avoid continuous operation:
Between 2,000 and 2,350 rpm.
Above 2,600 rpm in acrobatic flight.''
(3) For normal category airplanes, re-mark the engine tachometer
face or bezel with a red arc for the restricted engine speed range,
between 2,000 and 2,350 rpm.
(4) For acrobatic and utility airplanes, re-mark the engine
tachometer face or bezel with a red arc for each restricted engine
speed range, i.e., between 2,000 and 2,350 rpm and between 2,600 and
2,700 rpm (red line).
Models ( )HC-C2YK-( )( )( )/( )( )8475( )-( ) or ( )( )8477( )-( )
Propellers
(l) If propeller models ( )HC-C2YK-( )( )( )/( )( )8475( )-( )
or ( )( )8477( )-( ) have not been inspected and reworked in
accordance with AD 74-15-02, then do the following maintenance
before further flight.
(1) Remove propeller from airplane.
(2) Modify pitch change mechanism, and replace blades with
equivalent model blades prefixed with letter ``F'' using Hartzell
Service Letter No. 69, dated November 30, 1971 and Hartzell SB No.
101D, dated December 19, 1974.
(3) Inspect and repair or replace, if necessary, using Hartzell
