Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2011-1166; Directorate Identifier 2010-NM-169-AD; 
Amendment 39-16941; AD 2012-02-18]
RIN 2120-AA64


Airworthiness Directives; DASSAULT AVIATION Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
DASSAULT AVIATION Model MYSTERE-FALCON 50 airplanes. This AD was 
prompted by reports of cracking of the flap tracks. This AD requires 
revising the maintenance program to include revised airworthiness 
limitations. We are issuing this AD to prevent cracking of the flap 
tracks, which could lead to flap asymmetry and loss of control of the 
airplane.

DATES: This AD becomes effective April 4, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 4, 
2012.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on November 2, 2011 (76 
FR 67633). That NPRM proposed 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 ``Non-Destructive Check of Flap Tracks 2 
and 5,'' Maintenance Procedure 57-607, 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (76 FR 67633, November 2, 
2011) or on the determination of the cost to the public.

Explanation of Change Made to This AD

    We have revised the document citation for the service information 
referenced throughout this AD.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD with the change described 
previously--except for minor editorial changes. We have determined that 
these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (76 FR 67633, November 2, 2011) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 67633, November 2, 2011).

Costs of Compliance

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

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM (76 FR 67633,
