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 
Capitol Street, NW., suite 700, Washington, DC.

FOR FURTHER INFORMATION CONTACT: Tomaso DiPaolo, Aerospace Engineer, 
Chicago Aircraft Certification Office, FAA, Small Airplane Directorate, 
2300 East Devon Avenue, Des Plaines, IL 60018; telephone (847) 294-
7031; fax (847) 294-7834.

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.

    Note 1: This AD applies to each propeller identified in the 
preceding applicability provision, regardless of whether it has been 
modified, altered, or repaired in the area subject to the 
requirements of this AD. For propellers that have been modified, 
altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must request approval for an 
alternative method of compliance in accordance with paragraph (c) of 
this AD. The request should include an assessment of the effect of 
the modification, alteration, or repair on the unsafe condition 
addressed by this AD; and, if the unsafe condition has not been 
eliminated, the request should include specific proposed actions to 
address it.

    Compliance: Compliance with this AD is required as indicated, 
unless already done.
    To prevent propeller blade separation, damage to the airplane, 
and possible loss of the airplane, do the following:

or other approved procedures (excluding TKS Procedure P232) no 
further action is required.
    (b) For propellers that have had the anti-ice boots installed 
using the TKS Procedure P232, but have not had anti-ice boots re-
installed using Hartzell Manual 133C (ATA 61-13-33) ``Aluminum Blade 
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
