RIN 2120–AA64 Airworthiness Directives; McDonnell Douglas Model MD–90–30 Airplanes tjames on PRODPC61 with RULES AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. SUPPLEMENTARY INFORMATION: Discussion SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model MD–90–30 airplanes. This AD requires modifying the auxiliary hydraulic power system (including doing all applicable related investigative and corrective actions). This AD results from fuel system reviews conducted by the manufacturer, as well as reports of shorted wires in the right wheel well and evidence of arcing on the power cables of the auxiliary hydraulic pump. We are issuing this AD to prevent shorted wires or electrical arcing at the auxiliary hydraulic pump, which could result in a fire in the wheel well; and to reduce the potential of an ignition source adjacent to the fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. DATES: This AD becomes effective May 5, 2009. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of May 5, 2009. ADDRESSES: For service information identified in this AD, contact Boeing Commercial Airplanes, Attention: Data & Services Management, 3855 Lakewood Boulevard, MC D800–0019, Long Beach, California 90846–0001; telephone 206–544–5000, extension 2; fax 206–766–5683; e-mail dse.boecom@boeing.com; Internet https://www.myboeingfleet.com. Examining the AD Docket You may examine the AD docket on the Internet at https:// VerDate Nov<24>2008 14:33 Mar 30, 2009 Jkt 217001 www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The address for the Docket Office (telephone 800–647–5527) is the Document Management Facility, U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC 20590. The FAA issued a supplemental notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain McDonnell Douglas Model MD–90–30 airplanes. That supplemental NPRM was published in the Federal Register on December 19, 2008 (73 FR 77555). That supplemental NPRM proposed to require modifying the auxiliary hydraulic system (including doing all applicable related investigative and corrective actions). Comments We provided the public the opportunity to participate in the development of this AD. No comments have been received on the supplemental NPRM 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 in the supplemental NPRM. Costs of Compliance There are about 110 airplanes of the affected design in the worldwide fleet. This AD affects about 16 airplanes of U.S. registry. The actions take between 3 and 7 work-hours per airplane, depending on the configuration, at an average labor rate of $80 per work-hour. Required parts cost up to $5,343 per airplane. Based on these figures, the estimated cost of the AD for U.S. operators is up to $94,448, or $5,903 per airplane. PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 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 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 regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain McDonnell Douglas Model MD-90-30 airplanes. This AD requires 
modifying the auxiliary hydraulic power system (including doing all 
applicable related investigative and corrective actions). This AD 
results from fuel system reviews conducted by the manufacturer, as well 
as reports of shorted wires in the right wheel well and evidence of 
arcing on the power cables of the auxiliary hydraulic pump. We are 
issuing this AD to prevent shorted wires or electrical arcing at the 
auxiliary hydraulic pump, which could result in a fire in the wheel 
well; and to reduce the potential of an ignition source adjacent to the 
fuel tanks, which, in combination with flammable fuel vapors, could 
result in a fuel tank explosion and consequent loss of the airplane.

DATES: This AD becomes effective May 5, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of May 5, 2009.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a supplemental notice of proposed rulemaking (NPRM) 
to amend 14 CFR part 39 to include an AD that would apply to certain 
McDonnell Douglas Model MD-90-30 airplanes. That supplemental NPRM was 
published in the Federal Register on December 19, 2008 (73 FR 77555). 
That supplemental NPRM proposed to require modifying the auxiliary 
hydraulic system (including doing all applicable related investigative 
and corrective actions).

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the 
supplemental NPRM 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 
in the supplemental NPRM.

Costs of Compliance

    There are about 110 airplanes of the affected design in the 
worldwide fleet. This AD affects about 16 airplanes of U.S. registry. 
The actions take between 3 and 7 work-hours per airplane, depending on 
the configuration, at an average labor rate of $80 per work-hour. 
Required parts cost up to $5,343 per airplane. Based on these figures, 
the estimated cost of the AD for U.S. operators is up to $94,448, or 
$5,903 per airplane.

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 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 regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
