Download as PDF Federal Register / Vol. 76, No. 212 / Wednesday, November 2, 2011 / Proposed Rules ‘‘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 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), (3) Will not affect intrastate aviation in Alaska, and (4) 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. 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.

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 PO 00000 Frm 00014 Fmt 4702 Sfmt 4702 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 250 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $21,250, or $85 per product.

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 2010-0080, dated April 29, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    The Maintenance Procedure (MP) 57-607, related to non 
destructive check of the flap tracks 2 and 5, has been introduced 
thru revision 4 (01/2009) of section 5-10 of the Recommended 
Maintenance Schedules chapter of the Aircraft Maintenance 
Documentation.
    After the implementation of this MP cracks have been detected in 
service.
* * * * *
Cracking of the flap tracks could lead to flap asymmetry and loss of 
control of the airplane. The required actions include revising the 
maintenance program to include Dassault Aviation, Falcon 50/50EX 
Maintenance Manual, Non-Destructive Check of Flap Tracks 2 and 5, 57-
607, dated January 2009 (commonly referred to as Dassault Falcon 50/
50EX Maintenance Procedure 57-607, Non-Destructive Check of Flap Tracks 
2 and 5, of Chapter 5-40 Airworthiness Limitations, of the Dassault 
Falcon 50/50EX Maintenance Manual, Revision 21, dated June 2011). You 
may obtain further information by examining the MCAI in the AD docket.

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 250 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $21,250, or $85 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 67635]]

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.

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.


Sec.  39.13  [Amended]

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

Dassault Aviation: Docket No. FAA-2011-1166; Directorate Identifier 
2010-NM-169-AD.

Comments Due Date

    (a) We must receive comments by December 19, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Dassault Aviation Model Mystere-Falcon 50 
airplanes, all serial numbers, certificated in any category.

Subject

    (d) Air Transport Association (ATA) of America Code 57: Wings.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    The Maintenance Procedure (MP) 57-607, related to non 
destructive check of the flap tracks 2 and 5, has been introduced 
thru revision 4 (01/2009) of section 5-10 of the Recommended 
Maintenance Schedules chapter of the Aircraft Maintenance 
Documentation.
    After the implementation of this MP cracks have been detected in 
service.
* * * * *
Cracking of the flap tracks could lead to flap asymmetry and loss of 
control of the airplane.

Compliance

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Actions

    (g) Within 30 days after the effective date of the AD, revise 
the maintenance program to include Dassault Aviation, Falcon 50/50EX 
Maintenance Manual, Non-Destructive Check of Flap Tracks 2 and 5,

Tracks 2 and 5, of Chapter 5-40 Airworthiness Limitations, of the 
Dassault Falcon 50/50EX Maintenance Manual, Revision 21, dated June 
2011). The initial compliance time for doing the check is prior to 
the accumulation of 7,900 total flight cycles or within 600 flight 
cycles after the effective date of this AD, whichever occurs later.

No Alternative Actions or Intervals

    (h) After accomplishing the revision required by paragraph (g) 
of this AD, no alternative actions (e.g., inspections) or intervals 
may be used unless the actions or intervals are approved as an 
alternative method of compliance (AMOC) in accordance with the 
procedures specified in paragraph (i)(1) of this AD.
