14 CFR Part 39

[Docket No. FAA-2015-3144; Directorate Identifier 2014-NM-110-AD]
RIN 2120-AA64

Airworthiness Directives; Dassault Aviation

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 900EX airplanes and FALCON 
2000EX airplanes. This proposed AD was prompted by a report of 
significant fuel leakage at the middle position of the left outboard 
slat. This proposed AD would require modifying the assembly of the slat 
extension mechanical stop. We are proposing this AD to prevent failure 
of the assembly of the slat extension mechanical stop, which if not 
corrected, could lead to a significant fuel leak and result in an 
uncontained fire.

DATES: We must receive comments on this proposed AD by October 5, 2015.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0115, dated May 13, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Dassault 
Aviation Model FALCON 900EX airplanes and FALCON 2000EX airplanes. The 
MCAI states:

    After landing, an aeroplane experienced a significant fuel 
leakage at the middle position of the left outboard slat. 
Investigations showed that the fuel spillage originated in a 
structural cap, which had been punctured by a broken locking pin of 
the slat extension mechanical stop.
    A design review revealed that the locking pin could become loose 
due to an incorrect installation combined with a non-fault-tolerant 
design.
    This condition, if not corrected, may lead to a significant fuel 
leak, possibly resulting in an uncontained fire.
    To address this potential unsafe condition, Dassault Aviation 
developed a modification of the slat extension mechanical stop 
assembly (Mod M3678 for F2000EX aeroplanes and Mod M5870 for F900EX 
aeroplanes) with the purpose to increase its robustness with regards 
to possible mishandling on production or during maintenance. 
Dassault Aviation also published Service Bulletin (SB) F2000EX-344 
and SB F900EX-450, for embodiment in service of that modification.
    For the reasons described above, this [EASA AD] requires 
modification of the slat extension mechanical stop assembly.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
3144.

Related Service Information Under 1 CFR Part 51

    We reviewed Dassault Service Bulletin F900EX-450, dated March 10, 
2014; and Service Bulletin F2000EX-344, dated March 10, 2014. This 
service information describes procedures for modifying the assembly of 
the slat extension mechanical stop. This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section of this NPRM.

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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 67 airplanes of U.S. 
registry.
    We also estimate that it would take about 8 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 $3,510 
per product. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $280,730, or $4,190 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 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.
