Federal Aviation Administration

14 CFR Part 39

[Docket No. 2003-NE-44-AD; Amendment 39-13569; AD 2004-07-25]
RIN 2120-AA64


Airworthiness Directives; Hartzell Propeller Inc. Models HC-B5MP-
3C/M10876K Propellers

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) for Hartzell Propeller Inc. Model HC-B5MP-3C/M10876K propellers, 
installed on Short Brothers Model SD3-60 airplanes. That AD currently 
requires initial and repetitive removal, disassembly, inspection, and 
rework if necessary of Hartzell Propeller Inc. Model HC-B5MP-3C/M10876K 
propellers until blades are replaced with new design blades, no later 
than March 31, 1988. This ad requires installation of new design blades 
before further flight, on Hartzell Propeller Inc. Models HC-B5MP-3C/
M10876K propellers. This AD supersedure is prompted by a review of all 
currently effective ADs, which found that AD 87-16-02 was not published 
in the Federal Register to make it effective to all operators, as 
opposed to just the operators who received actual notice of the 
original AD. We are issuing this AD to prevent propeller blade 
separation near the hub, which could result in engine separation from 
the airplane.

DATES: This AD becomes effective May 21, 2004.

ADDRESSES: You may examine the AD docket, by appointment, at the FAA, 
New England Region, Office of the Regional Counsel, 12 New England 
Executive Park, Burlington, MA.

FOR FURTHER INFORMATION CONTACT: Melissa Bradley, Aerospace Engineer, 
Chicago Aircraft Certification Office, FAA, Small Airplane Directorate, 
2300 East Devon Avenue, Des Plaines, IL 60018; telephone: (847) 294-
8110; fax: (847) 294-7834.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with a proposed airworthiness directive (AD). The proposed AD applies 
to Hartzell Propeller Inc. Model HC-B5MP-3C/M10876K propellers. We 
published the proposed AD in the Federal Register on October 16, 2003 
(68 FR 59555). That action proposed to require installation of new 
design blades before further flight, on Hartzell Propeller Inc. Models 
HC-B5MP-3C/M10876K propellers.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the proposal or on 
the determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed.

Changes to 14 CFR Part 39--Effect on the AD

    On July 10, 2002, we issued a new version of 14 CFR part 39 (67 FR 
47998, July 22, 2002), which governs the FAA's AD system. That 
regulation now includes material that relates to altered products, 
special flight permits, and alternative methods of compliance. The 
material previously was included in each individual AD. Since the 
material is included in 14 CFR part 39, we will not include it in 
future AD actions.

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 by 
sending a request to us at the address listed under ADDRESSES. Include 
``AD Docket No. 2003-NE-44-AD'' in your request.
