Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) for certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-
FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. 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 resulted in the loss of 
some airplane functions. This action revises the NPRM by clarifying the 
applicability. We are proposing this supplemental NPRM (SNPRM) to 
prevent loss of electrical power and essential airplane functions, and 
possible reduced control of the airplane. Since these actions impose an 
additional burden over those proposed in the NPRM, we are reopening the 
comment period to allow the public the chance to comment on these 
proposed changes.

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 MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, 
and FALCON 2000EX airplanes. The NPRM published in the Federal Register 
on September 24, 2015 (80 FR 57545) (``the NPRM''). 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 NPRM proposed to require modification of the anti-collision light 
bonding.

Actions Since Previous NPRM Was Issued

    Since we issued the NPRM, we have determined that we inadvertently 
referred to specific service information to identify affected airplanes 
in figure 1 to paragraph (c) of the proposed AD (in the NPRM). In order 
to clarify the applicability and identify the affected airplanes as 
specified in European Aviation Safety Agency (EASA) Airworthiness 
Directive 2015-0006, dated January 15, 2015, we have removed references 
to specific service information from the applicability of this proposed 
AD.
    The 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.

Related Service Information Under 1 CFR Part 51

    Dassault Aviation has issued 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.
     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. 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.

Comments

    We gave the public the opportunity to participate in developing 
this proposed AD. We considered the comments received.

Request To Address the Original Grimes Anti-Collision Light 
Installation

    An anonymous commenter stated that the NPRM should address the 
original Grimes anti-collision light installation. This commenter 
asserted that any aircraft with the original Grimes anti-collision 
light installation would still be vulnerable to inadequate bonding.
    We acknowledge the commenter's request. However, we are not aware 
of an unsafe condition associated with the original Grimes anti-
collision light installation. We have determined that an unsafe 
condition exists on WHELEN anti-collision light installations and must 
be addressed. If we determine that an unsafe condition exists in the 
Grimes anti-collision light installation, we might consider further 
rulemaking. We have not changed this SNPRM regarding this issue.

Request To Reference the Revised Service Information

    NetJets Aviation requested that we revise the NPRM to refer to 
revised service information for the actions specified in paragraph (g) 
of the proposed AD (in the NPRM). NetJets Aviation stated that all 
service information identified in paragraphs (g)(1) through (g)(7) of 
the proposed AD (in the NPRM) have been revised.
    We agree that this SNPRM should refer to the most current service 
information. We have changed paragraph (g) of this proposed AD to refer 
to the revised service information. We have also added a new paragraph 
(h) to this proposed AD to provide credit for actions done ``before the 
effective date of this AD'' using the originally referenced service 
information. We have redesignated subsequent paragraphs accordingly.

[[Page 39599]]

Additional Change Made to This SNPRM

    We have retitled table 1 to paragraph (c) of the proposed AD (in 
the NPRM) to figure 1 to paragraph (c) of this proposed AD to meet the 
requirements of the Office of the Federal Register. This change is for 
formatting purposes only.

FAA's Determination and Requirements of This SNPRM

    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.
    Certain changes described above expand the scope of the NPRM. As a 
result, we have determined that it is necessary to reopen the comment 
period to provide additional opportunity for the public to comment on 
this SNPRM.

Costs of Compliance

    We estimate that this SNPRM 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 proposed 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 
proposed 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 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.
