14 CFR Part 39

[Docket No. FAA-2015-3144; Directorate Identifier 2014-NM-110-AD; 
Amendment 39-18403; AD 2016-04-09]
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 certain 
Dassault Aviation Model FALCON 900EX and FALCON 2000EX airplanes. This 
AD was prompted by a report of significant fuel leakage at the middle 
position of the left outboard slat. This AD would require modifying the 
assembly of the slat extension mechanical stop. We are issuing 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: This AD becomes effective April 5, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 5, 
2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Dassault Aviation 
Model FALCON 900EX and FALCON 2000EX airplanes. The NPRM published in 
the Federal Register on August 21, 2015 (80 FR 50810). The NPRM was 
prompted by a report of significant fuel leakage at the middle position 
of the left outboard slat. The NPRM proposed to require modifying the 
assembly of the slat extension mechanical stop. We are issuing 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.
    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 and FALCON 2000EX airplanes. The MCAI 
states:

    After landing, an airplane 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 [Model] F2000EX aeroplanes and Mod M5870 for 
[Model] 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 <a href="http://www.regulations.gov/#!documentDetail">http://www.regulations.gov/#!documentDetail</a>;D=FAA-2015-3144-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM (80 FR 
50810, August 21, 2015) and the FAA's response to that comment.

Request To Refer to the Latest Service Information

    Dassault Aviation requested that we refer to the latest service 
information: Erratum Service Bulletin F900EX-450, dated July 16, 2014; 
and Erratum Service Bulletin F2000EX-344, dated July 16, 2014. Dassault 
Aviation stated that it issued changes to Dassault Service Bulletin 
F900EX-450, dated March 10, 2014; and Dassault Service Bulletin 
F2000EX-344, dated March 10, 2014 (which we referred to as the 
appropriate sources of service information for accomplishing the 
actions specified in the proposed AD (80 FR 50810, August 21, 2015)).
    We agree with the commenter. Dassault Erratum Service Bulletin 
F900EX-450, dated July 16, 2014; and Erratum Service Bulletin F2000EX-
344, dated July 16, 2014; include among other minor changes, additional 
illustrations. We have revised paragraph (g) of this AD to refer to 
Dassault Erratum Service Bulletin F900EX-450, dated July 16, 2014; and 
Dassault Erratum Service Bulletin F2000EX-344, dated July 16, 2014. We 
have also added a new paragraph (h) to this AD to provide credit for 
the actions specified in paragraph (g) of this AD, if those actions are 
done before the effective date of this AD using Dassault Service 
Bulletin F900EX-450, dated March 10, 2014; or Dassault Service Bulletin 
F2000EX-344, dated March 10, 2014; as applicable. We have redesignated 
the subsequent paragraphs accordingly.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD with the changes described 
previously and minor editorial changes. We have determined that these 
minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (80 FR 50810, August 21, 2015) for correcting the unsafe 
condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 50810, August 21, 2015).

Related Service Information Under 1 CFR Part 51

    Dassault Aviation has issued Erratum Service Bulletin F900EX-450, 
dated July 16, 2014; and Erratum Service Bulletin F2000EX-344, dated 
July 16, 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.

Costs of Compliance

    We estimate that this AD affects 67 airplanes of U.S. registry.
    We also estimate that it will take about 8 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $3,510 per 
product. Based on these figures, we estimate the cost of this 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

[[Page 10459]]

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 that 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);
    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.
