ACTION: Final rule. SUMMARY: We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model 390 airplanes. This AD requires you to inspect the essential bus lightning strike protection for proper installation of metal oxide varistor (MOV) and spark gap wiring. This AD also requires you to rework the wiring as necessary to achieve the required lightning strike/ surge protection. This AD results from a report that the wires to the MOV and spark gap were swapped. We are issuing this AD to detect and correct improper installation of the MOV and spark gap wiring, which could result in overload of the MOV in a lightning strike and allow electrical energy to continue to the essential bus and disable equipment that receives power from the essential bus. The disabled equipment could include the autopilot, anti-skid system, hydraulic indicator, spoiler system, pilot primary flight display, audio panel, or the #1 air data computer. This failure could lead to a significant increase in pilot workload during adverse operating conditions. DATES: This AD becomes effective on June 21, 2010. On June 21, 2010, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD. ADDRESSES: For service information identified in this AD, contact Hawker Beechcraft Corporation, 9709 East Central, Wichita, Kansas 67201; telephone: (316) 676–5034; fax: (316) 676–6614; Internet: https:// www.hawkerbeechcraft.com/ service_support/pubs/.

SUPPLEMENTARY INFORMATION: Discussion On February 16, 2010, 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 Hawker Beechcraft Corporation Model 390 airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on February 23, 2010 (75 FR 8001). The NPRM proposed to require you to inspect the essential bus lightning strike protection for proper installation of metal oxide varistor (MOV) and spark gap wiring. The NPRM also proposed to require you to rework the wiring as necessary to achieve the required lightning strike/surge protection. 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 170 airplanes in the U.S. registry. We estimate the following costs to do the inspection (includes any necessary follow-on action): E:\FR\FM\17MYR1.SGM 17MYR1 27423 Federal Register / Vol. 75, No. 94 / Monday, May 17, 2010 / Rules and Regulations Total cost per airplane Labor cost Parts cost 3 work-hours × $85 per hour = $255 ................................................... Not applicable ............................... Warranty credit may be given to the extent specified in Hawker Beechcraft Mandatory Service Bulletin SB 24–3995, issued September 2009. 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: Total cost on U.S. operators $255 $43,350 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.

That NPRM specified that accomplishing the modification would end the repetitive inspections required by the existing AD for the length of lap joint that is modified. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments that have been received on the NPRM. Request for Certain Clarifications Boeing asks that we provide the following clarifications: • Include language in paragraph (c) of the NPRM which specifies that airplanes having line number 629, 635, 637, 650, 666, 667, 673, 675, 683, 713, 750, or 810 are Group 5 airplanes. Boeing states that after Boeing Service Bulletin 747–53A2367, Revision 3, dated January 15, 2009, was released, it was determined that these airplanes do not have a lower lobe air stair door and should have been included in Group 5, not Group 10. We agree with Boeing’s request for the reason provided. The airplane grouping is incorrect in Boeing Alert Service Bulletin 747–53A2367, Revision 2, dated October 30, 2008, and Boeing Service Bulletin 747–53A2367, Revision 3, dated January 15, 2009. Therefore, we have added a new Note 1 after paragraph (c) of this AD to clarify the correct airplane grouping for airplanes having the identified line numbers. • Change the term ‘‘Delegation Option Authorization’’ (DOA) to ‘‘Organization Designation Authorization’’ (ODA) throughout the NPRM. We agree. Boeing Commercial Airplanes has received an Organization Designation Authorization (ODA), which replaces the previous designation as a Delegation Option Authorization (DOA) holder. We have changed paragraph (m)(3) of this AD to add delegation of authority to Boeing Commercial Airplanes ODA to approve an alternative method of compliance for any repair required by this AD. • Change the Discussion section of the NPRM to note that AD 2009–04–16, Amendment 39–15822 (74 FR 8737, February 26, 2009), supersedes AD 2008–10–15, Amendment 39–15522 (73 FR 29042, May 20, 2008). Although we agree that AD 2009–04–16 superseded AD 2008–10–15, the discussion section of the NPRM is not carried over to this final rule. Therefore, we have made no change to the AD in this regard.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Hawker Beechcraft Corporation Model 390 airplanes. This AD requires you 
to inspect the essential bus lightning strike protection for proper 
installation of metal oxide varistor (MOV) and spark gap wiring. This 
AD also requires you to rework the wiring as necessary to achieve the 
required lightning strike/surge protection. This AD results from a 
report that the wires to the MOV and spark gap were swapped. We are 
issuing this AD to detect and correct improper installation of the MOV 
and spark gap wiring, which could result in overload of the MOV in a 
lightning strike and allow electrical energy to continue to the 
essential bus and disable equipment that receives power from the 
essential bus. The disabled equipment could include the autopilot, 
anti-skid system, hydraulic indicator, spoiler system, pilot primary 
flight display, audio panel, or the 1 air data computer. This 
failure could lead to a significant increase in pilot workload during 
adverse operating conditions.

DATES: This AD becomes effective on June 21, 2010.
    On June 21, 2010, the Director of the Federal Register approved the 
incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION:

Discussion

    On February 16, 2010, 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 Hawker Beechcraft Corporation Model 390 
airplanes. This proposal was published in the Federal Register as a 
notice of proposed rulemaking (NPRM) on February 23, 2010 (75 FR 8001). 
The NPRM proposed to require you to inspect the essential bus lightning 
strike protection for proper installation of metal oxide varistor (MOV) 
and spark gap wiring. The NPRM also proposed to require you to rework 
the wiring as necessary to achieve the required lightning strike/surge 
protection.

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 170 airplanes in the U.S. 
registry.
    We estimate the following costs to do the inspection (includes any 
necessary follow-on action):

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-2010-0158; Directorate Identifier 2010-CE-006-AD'' in your 
request.

    (d) Air Transport Association of America (ATA) Code 24: Electric 
Power.

Unsafe Condition

    (e) This AD results from a report that the metal oxide varistor 
(MOV) and spark gap wiring of the essential bus lightning strike 
protection were swapped. We are issuing this AD to detect and 
correct improper installation of the MOV and spark gap wiring, which 
could result in overload of the MOV in a lightning strike and allow 
electrical energy to continue to the essential bus and disable 
equipment that receives power from the essential bus. The disabled 
equipment could include the autopilot, anti-skid system, hydraulic 
indicator, spoiler system, pilot primary flight display, audio 
panel, or the 1 air data computer. This failure could lead 
to a significant increase in pilot workload during adverse operating 
conditions.
