Discussion On May 15, 2009, we issued AD 2009–11–09, Amendment 39–15919 (74 FR 25399, May 28, 2009). That AD required actions intended to address an unsafe condition on the products listed above. Since we issued AD 2009–11–09, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2010–0070, dated April 14, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Prompted by a reported in-service event, EASA issued AD 2009–0084 [which corresponds to FAA AD 2009–11–09] to prevent unwanted movement of pilot- or copilot seat in the horizontal direction which is considered as potentially unsafe, especially during the takeoff phase when the speed of the aeroplane is greater than 100 knots and until landing gear retraction. AD 2009–0084 required the deactivation of the electrical power of SOGERMA pilot seats P/N 2510112 series and co-pilot seats P/N 2510113 series. Optional intermediate actions were also provided by AD 2009–0084 to allow partial or full restoration of seat adjustment functionality. Since AD 2009–0084 was issued, a permanent solution has been developed that terminates the de-activation requirement and invalidates the intermediate actions. Consequently, this AD retains requirements of EASA AD 2009–0084, which is superseded, and requires implementing the terminating action. In addition, this AD prohibits the (re)installation of unmodified pilot- and co-pilot seats on any aeroplane that has been modified in accordance with the requirements of this AD. Uncommanded movement of the pilot and co-pilot seats during takeoff or landing could interfere with the operation of the airplane and, as a result, could cause loss of control of the airplane. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued the service information specified in the following table. TABLE—SERVICE INFORMATION Document Revision Airbus Mandatory Service Bulletin A300–25–6217 ....................................................... Airbus Mandatory Service Bulletin A310–25–2205 ....................................................... Original ........................................ Original ........................................ The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This 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 the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. jlentini on DSKJ8SOYB1PROD with PROPOSALS Differences Between This 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 VerDate Mar<15>2010 20:10 Nov 30, 2010 Jkt 223001 Date August 31, 2009. August 31, 2009. 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 highlighted in a NOTE within the proposed AD. for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $704,880, or $5,340 per product. Costs of Compliance 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. Based on the service information, we estimate that this proposed AD would affect about 132 products of U.S. registry. The actions that are required by AD 2009–11–09 and retained in this proposed AD take about 2 work-hours per product, at an average labor rate of $85 per work hour. Based on these figures, the estimated cost of the currently required actions is $170 per product. We estimate that it would take about 2 work-hours per product to comply with the new basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $5,000 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 Authority for This Rulemaking E:\FR\FM\01DEP1.SGM 01DEP1 Federal Register / Vol. 75, No. 230 / Wednesday, December 1, 2010 / Proposed Rules 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 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.

Airplanes)

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above that would supersede an existing AD. This 
proposed 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:

    Prompted by a reported in-service event, EASA issued AD 2009-
0084 to prevent unwanted movement of pilot- or co-pilot seat in the 
horizontal direction which is considered as potentially unsafe, 
especially during the takeoff phase when the speed of the aeroplane 
is greater than 100 knots and until landing gear retraction.
* * * * *

    Uncommanded movement of the pilot and co-pilot seats during takeoff 
or landing could interfere with the operation of the airplane and, as a 
result, could cause loss of control of the airplane. The proposed AD 
would require actions that are intended to address the unsafe condition 
described in the MCAI.

Discussion

    On May 15, 2009, we issued AD 2009-11-09, Amendment 39-15919 (74 FR 
25399, May 28, 2009). That AD required actions intended to address an 
unsafe condition on the products listed above.
    Since we issued AD 2009-11-09, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, has issued EASA Airworthiness Directive 2010-0070, 
dated April 14, 2010 (referred to after this as ``the MCAI''), to 
correct an unsafe condition for the specified products. The MCAI 
states:

    Prompted by a reported in-service event, EASA issued AD 2009-
0084 [which corresponds to FAA AD 2009-11-09] to prevent unwanted 
movement of pilot- or co-pilot seat in the horizontal direction 
which is considered as potentially unsafe, especially during the 
takeoff phase when the speed of the aeroplane is greater than 100 
knots and until landing gear retraction.
    AD 2009-0084 required the deactivation of the electrical power 
of SOGERMA pilot seats P/N 2510112 series and co-pilot seats P/N 
2510113 series. Optional intermediate actions were also provided by 
AD 2009-0084 to allow partial or full restoration of seat adjustment 
functionality.
    Since AD 2009-0084 was issued, a permanent solution has been 
developed that terminates the de-activation requirement and 
invalidates the intermediate actions.
    Consequently, this AD retains requirements of EASA AD 2009-0084, 
which is superseded, and requires implementing the terminating 
action. In addition, this AD prohibits the (re)installation of 
unmodified pilot- and co-pilot seats on any aeroplane that has been 
modified in accordance with the requirements of this AD.

    Uncommanded movement of the pilot and co-pilot seats during takeoff 
or landing could interfere with the operation of the airplane and, as a 
result, could cause loss of control of the airplane. You may obtain 
further information by examining the MCAI in the AD docket.

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

    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This 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 the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This 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 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 132 products of U.S. registry.
    The actions that are required by AD 2009-11-09 and retained in this 
proposed AD take about 2 work-hours per product, at an average labor 
rate of $85 per work hour. Based on these figures, the estimated cost 
of the currently required actions is $170 per product.
    We estimate that it would take about 2 work-hours per product to 
comply with the new basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $5,000 
per product. Where the service information lists required parts costs 
that are covered under warranty, we have assumed that there will be no 
charge for these costs. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of the proposed AD 
on U.S. operators to be $704,880, or $5,340 per product.

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.

[[Page 74667]]

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 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.
