Airworthiness Directives; Dassault Model Mystere-Falcon 20-C5, 
20-D5, 20-E5, and 20-F5 Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This 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:

    This Airworthiness Directive (AD) is issued following the 
discovery of hot air leaks when operating the wing anti-icing 
system. The seals Part Number (P/N) MS29513-325, near the de-icing 
valves (12H1) and (12H2) in frame 33 area, do not have the proper 
temperature rating.
    The consequences, in the area of the hot air leak, are risks of 
ignition of potential hydraulic leaks.
* * * * *
We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective August 12, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 12, 
2009.

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 March 26, 2009 (74 
FR 13147). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    This Airworthiness Directive (AD) is issued following the 
discovery of hot air leaks when operating the wing anti-icing 
system. The seals Part Number (P/N) MS29513-325, near the de-icing 
valves (12H1) and (12H2) in frame 33 area, do not have the proper 
temperature rating.
    The consequences, in the area of the hot air leak, are risks of 
ignition of potential hydraulic leaks.
    The purpose of this AD is to verify that seals with correct 
temperature rating have been installed on Mystere-Falcon 20-()5 
airplanes.

The corrective action includes replacing the left and right seals near 
de-icing valves (12H1) and (12H2) in frame area 33. 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 considered the comment received.

Request To Refer to Current Revision of the Service Bulletin

    Dassault Falcon Jet Corporation (Dassault) requests that we revise 
the NPRM to refer to Revision 1 of Dassault Mandatory Service Bulletin 
F20-766, dated June 24, 2008, in this AD. We referred to Dassault 
Service Bulletin F20-766, dated October 31, 2005, in the NPRM as the 
appropriate source of service information for doing the proposed 
requirements.
    We agree. Dassault Mandatory Service Bulletin F20-766, Revision 1, 
dated June 24, 2008, does not specify any additional action for 
airplanes on which the required actions have been accomplished in 
accordance with the original issue of Dassault Service Bulletin F20-
766, dated October 31, 2005. Also, paragraph 1.D. of Dassault Mandatory 
Service Bulletin F20-766,

[[Page 32420]]

Revision 1, dated June 24, 2008, revises the compliance to correspond 
with the MCAI. Therefore, we revised paragraphs (f) and (h) of this AD 
to refer to Dassault Mandatory Service Bulletin F20-766, Revision 1, 
dated June 24, 2008. We have also revised paragraph (f) of this AD to 
give credit for actions done before the effective date of this AD in 
accordance with Dassault Service Bulletin F20-766, dated October 31, 
2005.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the changes described previously. We determined that these 
changes will not increase the economic burden on any operator or 
increase the scope of the AD.

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 required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 187 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 $80 per work-hour. Based on these figures, we estimate the cost of 
this AD to the U.S. operators to be $14,960, or $80 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 AD:
    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 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, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

Service Bulletin F20-766 implemented.

Subject

    (d) Air Transport Association (ATA) of America Code 30: Ice and 
rain protection.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    This Airworthiness Directive (AD) is issued following the 
discovery of hot air leaks when operating the wing anti-icing 
system. The seals Part Number (P/N) MS29513-325, near the de-icing 
valves (12H1) and (12H2) in frame 33 area, do not have the proper 
temperature rating.
    The consequences, in the area of the hot air leak, are risks of 
ignition of potential hydraulic leaks.
    The purpose of this AD is to verify that seals with correct 
temperature rating have been installed on Mystere-Falcon 20-()5 
airplanes.

The corrective action includes replacing the left and right seals 
near de-icing valves (12H1) and (12H2) in frame area 33.

Actions and Compliance

    (f) Unless already done, within 7 months after the effective 
date of this AD, perform an inspection for a red line marking on 
each of the Wiggins couplings that are located near the de-icing 
valves (12H1) and (12H2), in accordance with Dassault Mandatory 
Service Bulletin F20-766, Revision 1, dated June 24, 2008. If a red 
line is not found, prior to further flight, replace the seals to the 
left and right Wiggins couplings, in accordance with Dassault 
Mandatory Service Bulletin F20-766, Revision 1, dated June 24, 2008. 
Inspections and replacements accomplished before the effective date 
of this AD in accordance with Dassault Service Bulletin F20-766, 
dated October 31, 2005, are considered acceptable for compliance 
with the corresponding actions specified in this AD.
