This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.
Federal Aviation Administration (FAA), DOT.
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.
This AD becomes effective May 21, 2004.
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.Start Further Info

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.
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.
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.
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.Start List of Subjects
