RIN 2120-AA64
Airworthiness Directives; Hartzell Propeller Inc. Model HC-
C2Y(K,R)-1BF/F8477-4 Propellers
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD), that
is applicable to certain Hartzell Propeller Inc. model HC-C2Y(K,R)-1BF/
F8477-4 propellers with TKS (Aircraft De-icing) Ltd. anti-ice boots
that were installed by SOCATA-Groupe AEROSPATIALE, the aircraft
manufacturer, using TKS Ltd. Procedure P232, Specification for the
Attachment of Propeller Overshoes. This amendment requires removal of
the anti-ice boots, inspection and rework of the anti-ice boot area of
the propeller blades, and installation of new anti-ice boots. This
amendment is prompted by a report of TKS (Aircraft De-icing) Ltd. anti-
ice boots on the blades of a model HC-C2Y(K,R)-1BF/F8477-4 propeller
that were installed by SOCATA-Groupe AEROSPATIALE using processes that
could lead to blade corrosion and failure. The actions specified by
this AD are intended to prevent propeller blade separation, damage to
the airplane, and possible loss of the airplane.
DATES: Effective April 29, 2003. The incorporation by reference of
certain publications listed in the regulations is approved by the
Director of the Federal Register as of April 29, 2003.
ADDRESSES: The service information referenced in this AD may be
obtained from Hartzell Propeller Inc. Technical Publications
Department, One Propeller Place, Piqua, OH 45356; telephone (937) 778-
4200; fax (937) 778-4391. This information may be examined, by
appointment, at the Federal Aviation Administration (FAA), New England
Region, Office of the Regional Counsel, 12 New England Executive Park,
Burlington, MA; or at the Office of the Federal Register, 800 North

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an AD that is
applicable to certain Hartzell Propeller Inc. model HC-C2Y(K,R)-1BF/
F8477-4 propellers with TKS (Aircraft De-icing) Ltd. anti-ice boots
that were installed by SOCATA-Groupe AEROSPATIALE, the aircraft
manufacturer, using TKS Ltd. Procedure P232, Specification for the
Attachment of Propeller Overshoes was published in the Federal Register
on November 21, 2002 (67 FR 70185). That action proposed to require
removal of the anti-ice boots, inspection and rework of the anti-ice
boot area of the propeller blades, and installation of new anti-ice
boots in accordance with Hartzell Propeller Inc. Alert Service Bulletin
(ASB) HC-ASB-61-251, dated April 10, 2001.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were received on the
proposal or the FAA's determination of the cost to the public. The FAA
has determined that air safety and the public interest require the
adoption of the rule as proposed.
Economic Analysis
There are approximately 750 Hartzell Propeller Inc. model HC-
C2Y(K,R)-1BF/F8477-4 propellers with TKS (Aircraft De-icing) Ltd. anti-
ice boots installed by SOCATA-Groupe AEROSPATIALE, the aircraft
manufacturer, using TKS Ltd. Procedure P232, Specification for the
Attachment of Propeller Overshoes. The FAA estimates that 230
propellers installed on airplanes of U.S. registry would be affected by
this AD. The FAA also estimates that it would take approximately 10
work hours per propeller to accomplish the actions, and that the
average labor rate is $60 per work hour. Required parts would cost
approximately $900 per propeller. Based on these figures, the total
cost of the AD to U.S. operators is estimated to be $345,000.
Regulatory Analysis
This final rule does not have federalism implications, as defined
in Executive Order 13132, because it would 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. Accordingly,
the FAA has not consulted with state authorities prior to publication
of this final rule.
For the reasons discussed above, I certify that this action (1) is
not a ``significant regulatory action'' under Executive Order 12866;
(2) is not a ``significant rule'' under the 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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
by contacting the Rules Docket at the location provided under the
caption ADDRESSES.

Overhaul'', AS&T Procedure 4700INS, or other approved procedures
(excluding TKS Procedure P232), remove anti-ice boots, inspect and
rework anti-ice boot areas of propeller blades, and install new
anti-ice boots in accordance with paragraph 3 of the Accomplishment
Instructions of Hartzell Propeller Inc. Alert Service Bulletin (ASB)
