RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
 ACTION: Final rule.
 SUMMARY: We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-46-350P and PA-46R-350T airplanes. This AD requires you to inspect the 35-amp and 250-amp current limiters to verify they are installed in the proper locations and correct the installation if the current limiters are not installed in the proper locations. This AD also limits operation to “only under day visual flight rules (VFR)” until the current limiter installation is inspected and corrected. This AD results from three reports of incorrectly installed current limiters. We are issuing this AD to detect and correct incorrect installation of 35-amp and 250-amp current limiters, which could result in failure of the 35-amp current limiter if installed in the 250-amp location. This failure could lead to a total loss of electrical power.
 DATES: This AD becomes effective on May 5, 2009. On May 5, 2009, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION: Discussion On January 7, 2009, we issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Piper Aircraft, Inc. Models PA-46-350P and PA-46R-350T airplanes. This proposal was published in the 
                    **Federal Register**
                     as a notice of proposed rulemaking (NPRM) on January 15, 2009 (74 FR 2425). The NPRM proposed to require an inspection to verify the 35-amp and 250-amp current limiters are installed in the proper locations and correct the installation if the current limiters are not installed in the proper locations. The NPRM also proposed to limit operation to only under day VFR until the current limiter installation is inspected and corrected.
                    ( print page 14462) Comments We provided the public the opportunity to participate in developing 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 except for minor editorial corrections. We have determined that these minor corrections: Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
                Do not add any additional burden upon the public than was already proposed in the NPRM. Costs of Compliance We estimate that this AD affects 118 airplanes in the U.S. registry. We estimate the following costs to do the inspection: Labor cost
Parts cost
Total cost per airplane
Total cost on U.S. operators1 work-hour × $80 per hour = $80
Not Applicable
$80
$9,440
 We estimate the following costs to do any necessary repairs that would be required based on the results of the proposed inspection. We have no way of determining the number of airplanes that may need this repair: Labor cost
Parts cost
Total cost per airplane1 work-hour × $80 per hour = $80
Not Applicable
$80
 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 AD. 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 other information as included in the Regulatory Evaluation) 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 “Docket No. FAA-2009-0007; Directorate Identifier 2008-CE-072-AD” in your request.  List of Subjects in 14 CFR Part 39 Air transportation

 2.FAA amends § 39.13 by adding the following new AD: **2009-07-08 Piper Aircraft, Inc.**
                            : Amendment 39-15867; Docket No. FAA-2009-0007; Directorate Identifier 2008-CE-072-AD. Effective Date (a) This AD becomes effective on May 5, 2009. Affected ADs (b) None. Applicability (c) This AD applies to the following airplane models and serial numbers that are certificated in any category: Models

 Unsafe Condition (d) This AD results from three reports of incorrectly installed current limiters. We are issuing this AD to detect incorrect installation of 35-amp and 250-amp current limiters, which could result in failure of the 35-amp current limiter if installed in the 250-amp location. This failure could lead to a total loss of electrical power. Compliance (e) To address this problem, you must do the following, unless already done:
