We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. This AD was prompted by a report of an in-flight lightning strike to the WHELEN anti- collision light located on the top of the vertical fin tip that caused severe damage and resulted in the loss of some airplane functions. This AD requires modification of the anti-collision light bonding. We are issuing this AD to prevent loss of electrical power and essential airplane functions, and possible reduced control of the airplane.

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 MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 
900EX, FALCON 2000, and FALCON 2000EX airplanes. This AD was prompted 
by a report of an in-flight lightning strike to the WHELEN anti-
collision light located on the top of the vertical fin tip that caused 
severe damage and resulted in the loss of some airplane functions. This 
AD requires modification of the anti-collision light bonding. We are 
issuing this AD to prevent loss of electrical power and essential 
airplane functions, and possible reduced control of the airplane.

DATES: This AD is effective November 22, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 22, 
2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 by adding an AD that would apply to certain 
Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 
900EX, FALCON 2000, and FALCON 2000EX airplanes. The SNPRM published in 
the Federal Register on June 17, 2016 (81 FR 39597) (``the SNPRM''). We 
preceded the SNPRM with a notice of proposed rulemaking (NPRM) that 
published in the Federal Register on September 24, 2015 (80 FR 57545) 
(``the NPRM''). The NPRM proposed to require modification of the anti-
collision light bonding. The NPRM was prompted by a report of an in-
flight lightning strike to the WHELEN anti-collision light located on 
the top of the vertical fin tip that caused severe damage and induced 
the loss of some airplane functions. The SNPRM proposed to clarify the 
applicability. We are issuing this AD to prevent loss of electrical 
power and essential airplane functions, and possible reduced control of 
the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0006, dated January 15, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Dassault 
Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 900EX, 
FALCON 2000, and FALCON 2000EX airplanes. The MCAI states:

    An occurrence was reported where a Falcon 2000 aeroplane 
experienced an in-flight lightning strike, which caused severe 
damage and induced the loss of some aeroplane functions. The 
investigation results revealed that the entering point of the 
lightning was at the WHELEN anti-collision light located on the top 
of the vertical fin tip.
    When the lightning strike hit the anti-collision light, an 
electric arc occurred between the aeroplane structure and the anti-
collision light and created a conductive path by which the lightning 
current entered inside the aeroplane. Further analysis has 
determined that the electrical bonding between the WHELEN anti-
collision light, Part Number (P/N) 01-0790044-09, and the fin tip 
fairing or the No. 2 engine air intake cover is insufficient to 
withstand a lightning strike.
    In case of severe lightning, this condition, if not corrected, 
could lead to an unsafe condition (loss of electrical power and/or 
of essential functions) possibly resulting in reduced control of the 
aeroplane.
    To address this potential unsafe condition, Dassault Aviation 
developed a modification (mod) to improve the WHELEN anti-collision 
light bonding when the anti-collision light is located on top of the 
vertical fin tip or on No. 2 engine air intake cover, and issued 
several Service Bulletins (SB) to modify all affected aeroplanes in 
service.
    For the reasons described above, this [EASA] AD requires 
modification of the anti-collision light bonding.

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-
3629.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the SNPRM or on the determination 
of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed the following service information.
     Dassault Service Bulletin F50-481, Revision 1 (also 
referred to as 481-R1), dated January 26, 2015.
     Dassault Service Bulletin F900-372, Revision 1 (also 
referred to as 372-R1), dated January 26, 2015.
     Dassault Service Bulletin F900-378, Revision 1 (also 
referred to as 378-R1), dated January 26, 2015.
     Dassault Service Bulletin F900EX-285, Revision 1 (also 
referred to as 285-R1), dated January 26, 2015.

[[Page 71587]]

     Dassault Service Bulletin F900EX-305, Revision 1 (also 
referred to as 305-R1), dated January 26, 2015.
     Dassault Service Bulletin F2000-337, Revision 1 (also 
referred to as 337-R1), dated January 26, 2015.
     Dassault Service Bulletin F2000EX-108, Revision 1 (also 
referred to as 108-R1), dated January 26, 2015.
    The service information describes procedures for modifying the 
anti-collision light bonding. These documents are distinct since they 
apply to different airplane models in different configurations. 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 778 airplanes of U.S. registry.
    We also estimate that it would take about 12 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts would cost about $801 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $1,416,738, or $1,821 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 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.
