ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model 390 airplanes. This proposed AD would require you to inspect the essential bus lightning strike protection for proper installation of metal oxide varistor (MOV) and spark gap wiring. This proposed AD would also require you to rework the wiring as necessary to achieve the required lightning strike/ surge protection. This proposed AD results from a report that the wires to the MOV and spark gap were swapped. We are proposing 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: We must receive comments on this proposed AD by April 9, 2010.

Discussion We received a report that on a Hawker Beechcraft Corporation Model 390 airplane the wires to the MOV and spark gap were swapped. The swapped wires were discovered during an inspection following a lightning strike. The spark gap has a higher current carrying capability than the MOV and is designed to carry direct currents caused by a lightning strike. In the event of a lightning strike, the potential exists to overload the MOV and allow an electrical spike to pass through to the essential bus. E:\FR\FM\23FEP1.SGM 23FEP1 8002 Federal Register / Vol. 75, No. 35 / Tuesday, February 23, 2010 / Proposed Rules This condition, if not corrected, could 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. Relevant Service Information We have reviewed Hawker Beechcraft Mandatory Service Bulletin SB 24–3995, issued September 2009. The service information describes procedures for inspecting the essential bus lightning strike protection for proper installation of MOV and spark gap wiring. The service information also describes procedures for rework as necessary to achieve the required lightning strike/ surge protection. require you to inspect the essential bus lightning strike protection for proper installation of MOV and spark gap wiring. This proposed AD would also require you to rework the wiring as necessary to achieve the required lightning strike/surge protection. FAA’s Determination and Requirements of the Proposed AD We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would We estimate that this proposed AD would affect 170 airplanes in the U.S. registry. We estimate the following costs to do the proposed inspection (includes any necessary follow-on action): Costs of Compliance Labor cost Parts cost Total cost per airplane Total cost on U.S. operators 3 work-hours × $85 per hour = $255 .............................................................................. Not applicable ........... $255 $43,350 Warranty credit may be given to the extent specified in Hawker Beechcraft Mandatory Service Bulletin SB 24–3995, issued September 2009. mstockstill on DSKH9S0YB1PROD with PROPOSALS 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; VerDate Nov<24>2008 16:24 Feb 22, 2010 Jkt 220001 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 regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. Examining the AD Docket You may examine the AD docket that contains the proposed AD, the regulatory evaluation, any comments received, and other information on the Internet at https://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 Docket Office (telephone (800) 647–5527) is located at the street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. PO 00000 Frm 00025 Fmt 4702 Sfmt 4702 § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: Hawker Beechcraft Corporation (Type Certificate No. A00010WI Previously Held By Raytheon Aircraft Company): Docket No. FAA–2010–0158; Directorate Identifier 2010–CE–006–AD. Comments Due Date (a) We must receive comments on this airworthiness directive (AD) action by April 9, 2010. Affected ADs (b) None. Applicability (c) This AD applies to Model 390 airplanes, serial numbers RB–4 through RB–248, that are certificated in any category. Subject (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, antiskid 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. Compliance (f) To address this problem, you must do the following, unless already done: E:\FR\FM\23FEP1.SGM 23FEP1 Federal Register / Vol. 75, No. 35 / Tuesday, February 23, 2010 / Proposed Rules 8003 Actions Compliance Procedures (1) Inspect the essential bus lightning strike protection for proper installation of MOV and spark gap wiring. Within the next 200 hours time-in-service after the effective date of this AD or within the next 12 months after the effective date of this AD, whichever occurs first. Before further flight after the inspection in paragraph (f)(1) of this AD. Follow Hawker Mandatory Service Bulletin SB 24–3995, issued September 2009. AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Several occurrences of loss of the AC [alternating current] BUS 1 have been reported which led in some instances to the loss of the AC ESS [essential] BUS and DC [direct current] ESS BUS and connected systems. The affected systems include multiple flight deck Display Units (Primary Flight Display, Navigation Display and Upper Electronic Centralised Aircraft Monitoring display). The loss of multiple display units, if not corrected expediently during a high workload period, potentially affects the capability of the flight crew and could contribute to a loss of situational awareness and consequent control of the aeroplane, which would constitute an unsafe condition. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by April 9, 2010.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Hawker Beechcraft Corporation Model 390 airplanes. This 
proposed AD would require you to inspect the essential bus lightning 
strike protection for proper installation of metal oxide varistor (MOV) 
and spark gap wiring. This proposed AD would also require you to rework 
the wiring as necessary to achieve the required lightning strike/surge 
protection. This proposed AD results from a report that the wires to 
the MOV and spark gap were swapped. We are proposing 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: We must receive comments on this proposed AD by April 9, 2010.

arguments regarding this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number, ``FAA-
2010-0158; Directorate Identifier 2010-CE-006-AD'' at the beginning of

Discussion

    We received a report that on a Hawker Beechcraft Corporation Model 
390 airplane the wires to the MOV and spark gap were swapped. The 
swapped wires were discovered during an inspection following a 
lightning strike. The spark gap has a higher current carrying 
capability than the MOV and is designed to carry direct currents caused 
by a lightning strike. In the event of a lightning strike, the 
potential exists to overload the MOV and allow an electrical spike to 
pass through to the essential bus.

[[Page 8002]]

    This condition, if not corrected, could 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.

Relevant Service Information

    We have reviewed Hawker Beechcraft Mandatory Service Bulletin SB 
24-3995, issued September 2009. The service information describes 
procedures for inspecting the essential bus lightning strike protection 
for proper installation of MOV and spark gap wiring. The service 
information also describes procedures for rework as necessary to 
achieve the required lightning strike/surge protection.

FAA's Determination and Requirements of the Proposed AD

    We are proposing this AD because we evaluated all information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design. This proposed AD 
would require you to inspect the essential bus lightning strike 
protection for proper installation of MOV and spark gap wiring. This 
proposed AD would also require you to rework the wiring as necessary to 
achieve the required lightning strike/surge protection.

Costs of Compliance

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

----------------------------------------------------------------------------------------------------------------
                                                                                 Total cost per   Total cost on
               Labor cost                              Parts cost                   airplane      U.S. operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255.....  Not applicable.......................            $255          $43,350

     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 
rulemaking action.

Regulatory Findings

    We have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    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 regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket that contains the proposed AD, the 
regulatory evaluation, any comments received, and other information on 
the Internet at https://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 Docket Office (telephone (800) 647-5527) 
is located at the street address stated in the ADDRESSES section. 
Comments will be available in the AD docket shortly after receipt.

Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Hawker Beechcraft Corporation (Type Certificate No. A00010WI 
Previously Held By Raytheon Aircraft Company): Docket No. FAA-2010-
0158; Directorate Identifier 2010-CE-006-AD.

Comments Due Date

    (a) We must receive comments on this airworthiness directive 
(AD) action by April 9, 2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model 390 airplanes, serial numbers RB-4 
through RB-248, that are certificated in any category.

Subject

    (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.

Compliance

    (f) To address this problem, you must do the following, unless 
already done:
