RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
 ACTION: Final rule; request for comments.
 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for Hamilton Sundstrand Propellers model 568F propellers with certain part number (P/N) and serial number (SN) blades. This AD requires removing affected propeller blades from service for rework. This AD results from reports of blades with corrosion pits in the tulip area of the blades. We are issuing this AD to prevent cracks from developing in the tulip area of the blade, which could result in separation of the blade and loss of airplane control.
 DATES: This AD becomes effective May 1, 2009. We must receive any comments on this AD by May 26, 2009.

SUPPLEMENTARY INFORMATION: We have received reports of corrosion on six propeller blades. A lack of adhesive and primer beyond the end of the compression wrap during manufacturing of certain serial-numbered propeller blades could result in corrosion pits developing in the tulip area of the propeller blade. This condition, if not corrected, could cause cracks in the tulip area, which could result in separation of the propeller blade and possible loss of airplane control. FAA's Determination and Requirements of This AD Although no airplanes that are registered in the United States use these propellers, the possibility exists that the propellers could be used on airplanes that are registered in the United States in the future. The unsafe condition described previously is likely to exist or develop on other Hamilton Sundstrand Propellers model 568F propellers of the same type design. We are issuing this AD to prevent cracks from developing in the tulip area of the blade, which could result in separation of the blade and loss of airplane control. This AD requires removing from service, Hamilton Sundstrand Propellers model 568F propellers, with a P/N and SN listed in Table 1 of this AD, within 30 days after the effective date of this AD. FAA's Determination of the Effective Date Since no domestic operators use this product, notice and opportunity for public comment before issuing this AD are unnecessary. Therefore, we are adopting this regulation immediately. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment; however, we invite you to send us any written relevant data, views, or arguments regarding this AD. Send your comments to an address listed under 
                    **ADDRESSES**
                    . Include “AD Docket No. FAA-2009-0270; Directorate Identifier 2008-NE-30-AD” in the subject line of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify it. We will post all comments we receive, without change, to 
                    *http://www.regulations.gov,*
                     including any personal information you provide. We will also post a report summarizing each substantive verbal contact with FAA personnel concerning this AD. Using the search function of the Web site, anyone can find and read the comments in any of our dockets, including, if provided, the name of the individual who sent the comment (or signed the comment on behalf of an association, business, labor union, etc.).

                    *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.

                     section. Comments will be available in the AD docket shortly after receipt. 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 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. 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
