Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2010–0029R1, dated November 25, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: On some Falcon 7X aeroplanes, it has been determined potential low clearance between electrical wiring or hydraulic pipe and nearby structure. VerDate Mar<15>2010 19:07 Mar 07, 2011 Jkt 223001 Although no in service incident has been reported, there is no certainty that the minimum clearances would be maintained over time. In the worst case, interference or contact with structure might occur and lead to electrical short circuits or fluid leakage, potentially resulting in loss of several functions essential for safe flight. Dassault Aviation has developed two Service Bulletins (SB) that provide corrective actions to ensure the minimum required clearance, as well as adequate protection between hydraulic pipe (SB n° 0 92) and electrical wiring (SB n° 006) and the aeroplane structure. This AD requires the implementation of both SBs on the affected aeroplanes. Since issuance of EASA AD 2010–0029, Dassault Aviation has developed modifications M1036 and M1037. M1036 is equivalent to M1007 while M1037 is equivalent to M1020. These modifications are embodied during production on new aeroplanes. This [EASA] AD has been revised to exclude from the AD applicability the aeroplanes on which those modifications are embodied. Required actions include general visual inspections for damage of wiring bundles and feeders. Damage includes, but is not limited to: signs of overheat, discoloration, or damaged and cut strands on the cables and insulating sleeves. Corrective actions for damage of wiring bundles and feeders include repairing damage. Other required actions include modifying the applicable wiring and layout, a general visual inspection for absence of marks of the rear tank wall at the contact area, installing a protective plate on the rear tank wall, and installing a hydraulic pipe if necessary. If contact marks are found, required actions include an eddy current inspection or a penetrant inspection for cracks, and repair if necessary. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Dassault has issued Mandatory Service Bulletin 7X–006, Revision 1, dated March 3, 2010; and Mandatory Service Bulletin 7X–092, Revision 1, dated January 4, 2010. 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 PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 12625 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 21 products of U.S. registry. We also estimate that it would take about 65 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $0 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 $116,025, or $5,525 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 E:\FR\FM\08MRP1.SGM 08MRP1 12626 Federal Register / Vol. 76, No. 45 / Tuesday, March 8, 2011 / Proposed Rules 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 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.

The MCAI describes the unsafe condition as: mstockstill on DSKH9S0YB1PROD with PROPOSALS SUMMARY: Since 2004, more than 30 reports have been received of in-flight loss of a rear passenger door on Diamond aeroplanes, the majority of which were DA 40. In additional, at least 18 doors have been replaced because of damage found on the hinge. Diamond Aircraft Industries conducted analyses and structural tests to determine the root cause of the door opening in flight. The conclusions were that the primary locking mechanism provided adequate strength to react to the loads in flight. It was also determined that the root cause was the crew not properly securing the rear passenger door by the main locking mechanism, prior to flight. Damage to the hinges has been caused primarily by external loads (wind gust conditions) while the aeroplane was parked. All DA 40 and DA 42 aeroplanes have a system installed that provides a warning if the main door latch is not fully closed and a secondary safety latch (with retaining bracket) design feature. The initial intended design function of the latch was to hold the rear passenger door in the ‘‘near closed’’ position while on the ground, protecting the door from wind gusts.

Airworthiness Directives; Dassault-Aviation Model FALCON 7X 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. 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:

    On some Falcon 7X aeroplanes, it has been determined potential 
low clearance between electrical wiring or hydraulic pipe and nearby 
structure. Although no in service incident has been reported, there 
is no certainty that the minimum clearances would be maintained over 
time. In the worst case, interference or contact with structure 
might occur and lead to electrical short circuits or fluid leakage, 
potentially resulting in loss of several functions essential for 
safe flight.
* * * * *

    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 22, 2011.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2010-0029R1, dated November 25, 2010 (referred 
to after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    On some Falcon 7X aeroplanes, it has been determined potential 
low clearance between electrical wiring or hydraulic pipe and nearby 
structure.
    Although no in service incident has been reported, there is no 
certainty that the minimum clearances would be maintained over time. 
In the worst case, interference or contact with structure might 
occur and lead to electrical short circuits or fluid leakage, 
potentially resulting in loss of several functions essential for 
safe flight.
    Dassault Aviation has developed two Service Bulletins (SB) that 
provide corrective actions to ensure the minimum required clearance, 
as well as adequate protection between hydraulic pipe (SB n[deg] 0 
92) and electrical wiring (SB n[deg] 006) and the aeroplane 
structure.
    This AD requires the implementation of both SBs on the affected 
aeroplanes.
    Since issuance of EASA AD 2010-0029, Dassault Aviation has 
developed modifications M1036 and M1037. M1036 is equivalent to 
M1007 while M1037 is equivalent to M1020. These modifications are 
embodied during production on new aeroplanes.
    This [EASA] AD has been revised to exclude from the AD 
applicability the aeroplanes on which those modifications are 
embodied.

    Required actions include general visual inspections for damage of 
wiring bundles and feeders. Damage includes, but is not limited to: 
signs of overheat, discoloration, or damaged and cut strands on the 
cables and insulating sleeves. Corrective actions for damage of wiring 
bundles and feeders include repairing damage. Other required actions 
include modifying the applicable wiring and layout, a general visual 
inspection for absence of marks of the rear tank wall at the contact 
area, installing a protective plate on the rear tank wall, and 
installing a hydraulic pipe if necessary. If contact marks are found, 
required actions include an eddy current inspection or a penetrant 
inspection for cracks, and repair if necessary. You may obtain further 
information by examining the MCAI in the AD docket.

Relevant Service Information

    Dassault has issued Mandatory Service Bulletin 7X-006, Revision 1, 
dated March 3, 2010; and Mandatory Service Bulletin 7X-092, Revision 1, 
dated January 4, 2010. 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 21 products of U.S. registry. We also estimate that 
it would take about 65 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about $0 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 $116,025, or $5,525 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

[[Page 12626]]

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 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.
