Model 750XL Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). sroberts on PROD1PC70 with PROPOSALS AGENCY: SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Corporation Ltd. Model 750XL airplanes. This proposed AD would require you to inspect the condition of the insulation of the wiring adjacent to the electrical plugs mounted in the left-hand (LH) and right-hand (RH) sides of the forward end of the cockpit center console for signs of abrasion and arcing. If you find evidence of abrasion or arcing, this proposed AD would require you to replace the affected wire(s) and secure the wires away from the back shells of the electrical plugs. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand. We are proposing this AD to detect and correct damaged wires on the LH and RH sides of the forward end of the cockpit center console, which could result in short-circuiting of the related wiring. This could lead to electrical failure of affected systems and potential fire in the cockpit. DATES: We must receive comments on this proposed AD by April 24, 2006. ADDRESSES: Use one of the following addresses to comment on this proposed AD: • DOT Docket Web site: Go to http:// dms.dot.gov and follow the instructions for sending your comments electronically. • Government-wide rulemaking Web site: Go to http://www.regulations.gov VerDate Aug<31>2005 20:46 Mar 24, 2006 Jkt 208001 and follow the instructions for sending your comments electronically. • Mail: Docket Management Facility; U.S. Department of Transportation, 400 Seventh Street, SW., Nassif Building, Room PL–401, Washington, DC 20590– 0001. • Fax: (202) 493–2251. • Hand Delivery: Room PL–401 on the plaza level of the Nassif Building, 400 Seventh Street, SW., Washington, DC, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Discussion The Civil Aviation Authority (CAA), which is the airworthiness authority for New Zealand, notified the Federal Aviation Administration (FAA) that an unsafe condition may exist on certain Pacific Aerospace Corporation Ltd. (Pacific Aerospace) Model 750XL airplanes. The CAA reports an incident in which short-circuiting of the wiring in the cockpit center console occurred. Abrasion of the wiring insulation caused by the fasteners of the electrical plug back-shells located in the cockpit center console resulted in the shortcircuit. PO 00000 Frm 00015 Fmt 4702 Sfmt 4702 15061 This condition, if not corrected, could result in short-circuiting of the related wiring in the forward end of the cockpit center console. This could lead to electrical failure of affected systems and potential fire in the cockpit. Relevant Service Information We have reviewed Pacific Aerospace Corporation Mandatory Service Bulletin No. PACSB/XL/016, Issue 1, Date Issued: September 23, 2005. The service information describes procedures for: • Inspecting the condition of the insulation of the wiring adjacent to the electrical plugs mounted in the lefthand (LH) and (RH) right-hand sides of the forward end of the cockpit center console for signs of abrasion and arcing; • Replacing the affected wire(s) if any evidence of abrasion or arcing is found; and • Securing the wires away from the back shells of the electrical plugs. Foreign Airworthiness Authority Information The CAA classified this service bulletin as mandatory and issued New Zealand AD Number DCA/750XL/6, Effective Date: December 1, 2005, to ensure the continued airworthiness of these airplanes in New Zealand. These Pacific Aerospace Model 750XL airplanes are manufactured in New Zealand and are type-certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Under this bilateral airworthiness agreement, the CAA has kept us informed of the situation described above. FAA’s Determination and Requirements of the Proposed AD We are proposing this AD because we have examined the CAA’s findings, evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design that are certificated for operation in the United States. This proposed AD would require you to inspect the condition of the insulation of the wiring adjacent to the electrical plugs mounted in the LH and RH sides of the forward end of the cockpit center console for signs of abrasion and arcing. If any evidence of abrasion or arcing is found, this proposed AD would require you to replace the affected wire(s) and secure the wires away from the back shells of the electrical plugs. E:\FR\FM\27MRP1.SGM 27MRP1 15062 Federal Register / Vol. 71, No. 58 / Monday, March 27, 2006 / Proposed Rules Costs of Compliance We estimate the following costs to do the proposed inspection: We estimate that this proposed AD would affect 5 airplanes in the U.S. registry.

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 http://dms.dot.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Pacific Aerospace Corporation Ltd. Model 750XL airplanes. This 
proposed AD would require you to inspect the condition of the 
insulation of the wiring adjacent to the electrical plugs mounted in 
the left-hand (LH) and right-hand (RH) sides of the forward end of the 
cockpit center console for signs of abrasion and arcing. If you find 
evidence of abrasion or arcing, this proposed AD would require you to 
replace the affected wire(s) and secure the wires away from the back 
shells of the electrical plugs. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) issued by the airworthiness 
authority for New Zealand. We are proposing this AD to detect and 
correct damaged wires on the LH and RH sides of the forward end of the 
cockpit center console, which could result in short-circuiting of the 
related wiring. This could lead to electrical failure of affected 
systems and potential fire in the cockpit.

Discussion

    The Civil Aviation Authority (CAA), which is the airworthiness 
authority for New Zealand, notified the Federal Aviation Administration 
(FAA) that an unsafe condition may exist on certain Pacific Aerospace 
Corporation Ltd. (Pacific Aerospace) Model 750XL airplanes. The CAA 
reports an incident in which short-circuiting of the wiring in the 
cockpit center console occurred.
    Abrasion of the wiring insulation caused by the fasteners of the 
electrical plug back-shells located in the cockpit center console 
resulted in the short-circuit.
    This condition, if not corrected, could result in short-circuiting 
of the related wiring in the forward end of the cockpit center console. 
This could lead to electrical failure of affected systems and potential 
fire in the cockpit.

Relevant Service Information

    We have reviewed Pacific Aerospace Corporation Mandatory Service 
Bulletin No. PACSB/XL/016, Issue 1, Date Issued: September 23, 2005.
    The service information describes procedures for:
     Inspecting the condition of the insulation of the wiring 
adjacent to the electrical plugs mounted in the left-hand (LH) and (RH) 
right-hand sides of the forward end of the cockpit center console for 
signs of abrasion and arcing;
     Replacing the affected wire(s) if any evidence of abrasion 
or arcing is found; and
     Securing the wires away from the back shells of the 
electrical plugs.

Foreign Airworthiness Authority Information

    The CAA classified this service bulletin as mandatory and issued 
New Zealand AD Number DCA/750XL/6, Effective Date: December 1, 2005, to 
ensure the continued airworthiness of these airplanes in New Zealand.
    These Pacific Aerospace Model 750XL airplanes are manufactured in 
New Zealand and are type-certificated for operation in the United 
States under the provisions of section 21.29 of the Federal Aviation 
Regulations (14 CFR 21.29) and the applicable bilateral airworthiness 
agreement.
    Under this bilateral airworthiness agreement, the CAA has kept us 
informed of the situation described above.

FAA's Determination and Requirements of the Proposed AD

    We are proposing this AD because we have examined the CAA's 
findings, evaluated all information and determined the unsafe condition 
described previously is likely to exist or develop on other products of 
the same type design that are certificated for operation in the United 
States.
    This proposed AD would require you to inspect the condition of the 
insulation of the wiring adjacent to the electrical plugs mounted in 
the LH and RH sides of the forward end of the cockpit center console 
for signs of abrasion and arcing. If any evidence of abrasion or arcing 
is found, this proposed AD would require you to replace the affected 
wire(s) and secure the wires away from the back shells of the 
electrical plugs.

[[Page 15062]]

Costs of Compliance

    We estimate that this proposed AD would affect 5 airplanes in the 
U.S. registry.
    We estimate the following costs to do the proposed inspection:

----------------------------------------------------------------------------------------------------------------
                                                                Total cost  per
             Labor cost                      Parts cost            airplane       Total cost on  U.S. operators
----------------------------------------------------------------------------------------------------------------
4 work hours x $80 per hour = $320..  Not applicable.........             $320   $320 x 5 = $1,600
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
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 replacement:

------------------------------------------------------------------------
                                                             Total cost
                 Labor cost                    Parts cost   per airplane
------------------------------------------------------------------------
28 work hours x $80 per hour = $2,240.......         $200        $2,440
------------------------------------------------------------------------

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 http://dms.dot.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) 647-5227) 
is located at the street address stated in the ADDRESSES section. 
Comments will be available in the AD docket shortly after receipt.
