Airworthiness Directives; Alpha Aviation Design Limited (Type Certificate No. A48EU Previously Held by APEX Aircraft and Avions Pierre ROBIN) Model R2160 Airplanes, 57896-57898 [E7-20047]

Download as PDF 57896 Federal Register / Vol. 72, No. 196 / Thursday, October 11, 2007 / Proposed Rules the service information is intended to adequately address the unsafe condition. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other airplanes of this same type design. For this reason, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously. Costs of Compliance 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. See the ADDRESSES section for a location to examine the regulatory evaluation. There are about 134 airplanes of the affected design in the worldwide fleet. This proposed AD would affect about 104 airplanes of U.S. registry. The proposed actions would take about 4 work hours per airplane, at an average labor rate of $80 per work hour. Required parts would cost about $9 per airplane. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $34,216, or $329 per airplane. List of Subjects in 14 CFR Part 39 Authority for This Rulemaking 1. The authority citation for part 39 continues to read as follows: 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. mstockstill on PROD1PC66 with PROPOSALS 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: VerDate Aug<31>2005 14:15 Oct 10, 2007 Jkt 214001 Air transportation, Aircraft, Aviation safety, Safety.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion The Civil Aviation Authority (CAA), which is the airworthiness authority for New Zealand, has issued AD DCA/ R2000/28, dated September 28, 2006 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: To prevent failure of the wing structure and assembly components due to undetected fatigue and corrosion * * * The MCAI requires that you inspect the wing structure and fuselage attachment and repair any defects that you find. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Avions Pierre Robin (recent type certificate responsibility was with APEX Aircraft and current responsibility with Alpha Aviation Design Limited) has issued Service Bulletin No. 123, revision 2, dated November 14, 1995; and Mandatory Service Bulletin No. 123, revision 3, issued December 23, 1999. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This Proposed AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 57897 different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are described in a separate paragraph of the proposed AD. These requirements, if ultimately adopted, will take precedence over the actions copied from the MCAI. Costs of Compliance We estimate that this proposed AD will affect 10 products of U.S. registry. We also estimate that it will take about 15 work-hours per product to comply with basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Required parts will cost about $1,326 per product. Based on these figures, we estimate the cost of this proposed AD to the U.S. operators to be $25,260 or $2,526 per product. We have no way to determine what aircraft will need replacement parts that may be required based on the results of any inspection.

Discussion

    The Civil Aviation Authority (CAA), which is the airworthiness 
authority for New Zealand, has issued AD DCA/R2000/28, dated September 
28, 2006 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    To prevent failure of the wing structure and assembly components 
due to undetected fatigue and corrosion * * *

The MCAI requires that you inspect the wing structure and fuselage 
attachment and repair any defects that you find.

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Avions Pierre Robin (recent type certificate responsibility was 
with APEX Aircraft and current responsibility with Alpha Aviation 
Design Limited) has issued Service Bulletin No. 123, revision 2, dated 
November 14, 1995; and Mandatory Service Bulletin No. 123, revision 3, 
issued December 23, 1999.
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed AD and the MCAI or Service 
Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
described in a separate paragraph of the proposed AD. These 
requirements, if ultimately adopted, will take precedence over the 
actions copied from the MCAI.

Costs of Compliance

    We estimate that this proposed AD will affect 10 products of U.S. 
registry. We also estimate that it will take about 15 work-hours per 
product to comply with basic requirements of this proposed AD. The 
average labor rate is $80 per work-hour. Required parts will cost about 
$1,326 per product.
    Based on these figures, we estimate the cost of this proposed AD to 
the U.S. operators to be $25,260 or $2,526 per product.
    We have no way to determine what aircraft will need replacement 
parts that may be required based on the results of any inspection.

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 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

[[Page 57898]]

responsibilities among the various levels of government.
    For the reasons discussed above, I certify this 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.
