Airworthiness Directives; Dassault Aviation Model Mystere-Falcon 
50 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:

    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.

[[Page 67634]]

    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 proposed AD would require actions that 
are intended to address the unsafe condition described in the MCAI.

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 2010-0080, 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.
    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.

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,

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)

    Note 1: This AD differs from the MCAI and/or service information 
as follows:

    No difference.

office. The AMOC approval letter must specifically reference this 
AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
