Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2016-17-
02 for certain Dassault Aviation Model FALCON 900EX and FALCON 2000EX 
airplanes. AD 2016-17-02 currently requires revising the airplane 
flight manual (AFM) to include procedures to follow when an airplane is 
operating in icing conditions. AD 2016-17-02 also provides optional 
actions after which the AFM revision may be removed from the AFM. Since 
we issued AD 2016-17-02, we have determined additional actions are 
necessary to address the identified unsafe condition. This proposed AD 
would retain the requirement of AD 2016-17-02 and, in addition, require 
a detailed inspection of the wing anti-ice system ducting (anti-ice 
pipes) for the presence of a diaphragm, and replacement of ducting or 
re-identification of the ducting part marking. We are proposing this AD 
to address the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by July 14, 2017.

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

Discussion

    On August 5, 2016, we issued AD 2016-17-02, Amendment 39-18615 (81 
FR 55366, August 19, 2016) (``AD 2016-17-02''), for certain Dassault 
Aviation Model FALCON 900EX and FALCON 2000EX airplanes. AD 2016-17-02 
was prompted by a design review of in-production airplanes that 
identified a deficiency in certain wing anti-ice system ducting. A 
deficiency in the wing anti-ice system ducting could lead to 
undetected, reduced performance of the wing anti-ice system, with 
potential ice accretion and ingestion, possibly resulting in degraded 
engine power and degraded handling characteristics of the airplane. AD 
2016-17-02 requires revising the AFM to include procedures to follow 
when an airplane is operating in icing conditions. AD 2016-17-02 also 
provides optional actions after which the AFM revision may be removed 
from the AFM. We issued AD-2016-17-02 to ensure the flight crew has 
procedures for operating an airplane in icing conditions.
    When we issued AD 2016-17-02, we stated that it was an interim 
action and we were considering additional rulemaking to require a 
detailed inspection of the wing anti-icing system ducting for the 
presence of a diaphragm and, as applicable, re-identification or 
replacement of the wing anti-icing system ducting (these actions are 
required by the MCAI). We have determined that requiring those 
additional actions are necessary to address the identified unsafe 
condition.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Emergency Airworthiness Directive 2016-0130-E, dated July 5, 2016 
(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:

    A design review of in production aeroplanes identified a 
manufacturing deficiency of some wing anti-ice system ducting.
    This condition, if not detected and corrected, could lead to an 
undetected reduced performance of the wing anti-ice system, with 
potential ice accretion and ingestion, possibly resulting in 
degraded engine power and degraded handling characteristics.
    The Falcon 900EX EASY and Falcon . . . [2000EX] Aircraft Flight 
Manuals (AFM) contain a normal procedure 4-200-05A, ``Operations in 
Icing Conditions'', addressing minimum fan speed rotation (N1) 
during combined operation of wing anti-ice and engine anti-ice 
systems. The subsequent investigation demonstrated that the wing 
anti-ice system performance for aeroplanes equipped with ducting 
affected by the manufacturing deficiency can be restored increasing 
N1 value. In addition, Dassault Aviation published Service Bulletin 
(SB) F900EX-464 (for Falcon 900EX aeroplanes) and SB F2000EX-393 
(for Falcon 2000EX aeroplanes), providing instructions for wing 
anti-ice system ducting inspection.
    For the reasons described above, this [EASA] AD requires an AFM 
amendment and a one-time [detailed] inspection of the wing anti-ice 
system ducting [and, as applicable, a check of the part number,] 
and, depending on findings, re-identification or replacement of the 
wing anti-ice system ducting.

    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-2017-
0494.

Related Service Information Under 1 CFR Part 51

    Dassault has issued Service Bulletin F900EX-464, dated June 20, 
2016; and Service Bulletin F2000EX-393, dated June 20, 2016. The 
service information describes procedures for an inspection of the wing 
anti-ice system ducting and re-identification or replacement of the 
wing anti-ice system ducting. These documents are distinct since they 
apply to different airplane models. 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.

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 52 airplanes of U.S. 
registry.
    The action required by AD 2016-17-02, and retained in this proposed 
AD takes about 1 work-hour per product, at an average labor rate of $85 
per work-hour. Based on these figures, the estimated cost of the action 
that is required by AD 2016-17-02 is $85 per product.
    We also estimate that it would take about 4 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $17,680, or $340 
per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 19 work-hours and require parts costing $24,000, for a cost 
of $25,615 per product. We have no way of determining the number of 
aircraft that might need these actions.

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.
