14 CFR Part 39

[Docket No. FAA-2012-1067; Directorate Identifier 2011-NM-231-AD]
RIN 2120-AA64


Airworthiness Directives; DASSAULT AVIATION Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain DASSAULT AVIATION Model FALCON 2000, FALCON 2000EX, MYSTERE-
FALCON 900 and FALCON 900EX airplanes; and all Model MYSTERE-FALCON 50 
airplanes. This proposed AD was prompted by reports that collapse of 
the main landing gear (MLG) could cause wing tank structure failure, 
which could result in fuel spillage and consequent fire hazard. This 
proposed AD would require modification of the wing fuel tanks in the 
area of the wheel well. We are proposing this AD to prevent fuel 
spillage in the event of a MLG collapse, and consequent fire hazard.

DATES: We must receive comments on this proposed AD by November 26, 
2012.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

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 2011-0193, dated October 5, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    In service experience has shown that, in case of main landing 
gear collapse due to overloads during take off or landing (e.g., 
during high-speed runway excursions), the wing tank structure can 
fail, leading to fuel spillage. * * *
    This condition, if not corrected, could result, in case of main 
landing gear collapse, in a fuel spillage which may constitute a 
fire hazard.
    To address this unsafe condition, Dassault Aviation have 
developed a structural modification of the wing fuel tanks in the 
area of the wheel well which introduces a dry bay by adding a sealed 
boundary in front of the rear spar between ribs 4 and 5.
    For the reasons described above, this [EASA] AD requires 
accomplishment of the above-mentioned modification for the Right 
Hand (RH) and Left Hand (LH) wing fuel tanks.

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.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 753 products of U.S. registry. We also estimate that 
it would take about 640 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 $18,500 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 
parts. 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 $54,893,700, or $72,900 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 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 that 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 proposed AD and placed it in the AD docket.

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. 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-2012-1067; Directorate Identifier 
2011-NM-231-AD.

(a) Comments Due Date

    We must receive comments by November 26, 2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the airplanes specified in paragraphs (c)(1), 
(c)(2), and (c)(3) of this AD, certificated in any category.

could result in fuel spillage and a consequent fire hazard. We are 
issuing this AD to prevent fuel spillage in the event of a MLG 
collapse, and consequent fire hazard.

modification of the right-hand and left-hand wing fuel tanks, in 
accordance with the Accomplishment Instructions of the applicable 
service information specified in paragraph (g)(1), (g)(2), (g)(3), 
(g)(4), or (g)(5) of this AD, as applicable. The service information

(i) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the International
