Federal Register Volume 82, Issue 222 (November 20, 2017)

We are superseding Airworthiness Directive (AD) 2017-19-17, which applied to certain Dassault Aviation Model FALCON 900EX and FALCON 2000EX airplanes. AD 2017-19-17 required revising the airplane flight manual (AFM) to include procedures to follow when an airplane is operating in icing conditions. AD 2017-19-17 also required a detailed inspection of the wing anti-ice system ducting for the presence of a diaphragm, and follow-on actions (replacement of ducting or re- identification of the ducting part marking). This new AD retains the actions required by AD 2017-19-17, and corrects the follow-on actions for certain airplanes. This AD was prompted by a determination that the follow-on actions specified in AD 2017-19-17 were incorrect for certain airplanes. We are issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2017-19-17, 
which applied to certain Dassault Aviation Model FALCON 900EX and 
FALCON 2000EX airplanes. AD 2017-19-17 required revising the airplane 
flight manual (AFM) to include procedures to follow when an airplane is 
operating in icing conditions. AD 2017-19-17 also required a detailed 
inspection of the wing anti-ice system ducting for the presence of a 
diaphragm, and follow-on actions (replacement of ducting or re-
identification of the ducting part marking). This new AD retains the 
actions required by AD 2017-19-17, and corrects the follow-on actions 
for certain airplanes. This AD was prompted by a determination that the 
follow-on actions specified in AD 2017-19-17 were incorrect for certain 
airplanes. We are issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective December 1, 2017.
    The Director of the Federal Register approved the incorporation by

Discussion

    We issued AD 2017-19-17, Amendment 39-19047 (82 FR 44305, September 
22, 2017) (``AD 2017-19-17''), which applied to certain Dassault 
Aviation Model FALCON 900EX and FALCON 2000EX airplanes. AD 2017-19-17 
superseded AD 2016-17-02, Amendment 39-18615 (81 FR 55366, August 19, 
2016). AD 2017-19-17 was prompted by a design review of in-production 
airplanes that identified a deficiency in certain wing anti-ice system 
ducting. AD 2017-19-17 required revision of the AFM to include 
procedures to follow when an airplane is operating in icing conditions, 
the detailed inspection of the wing anti-ice system ducting for the 
presence of a diaphragm, and replacement of ducting or re-
identification of the ducting part marking. We issued AD 2017-19-17 to 
detect and correct a deficiency in the wing anti-ice system ducting, 
which could result in reduced performance of the wing anti-ice system 
with potential ice accretion and ingestion, and could result in 
degraded engine power and degraded handling characteristics.
    Since we issued AD 2017-19-17, we found that the follow-on actions 
specified in paragraphs (h)(1) and (h)(2) of AD 2017-19-17 are correct 
for Model FALCON 900EX airplanes. However, for Model FALCON 2000EX 
airplanes, the follow-on actions specified in paragraphs (h)(1) and 
(h)(2) of AD 2017-19-17 would be dependent on different conditions than 
those specified for Model FALCON 900EX airplanes. This AD corrects 
those actions for Model FALCON 2000EX airplanes.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Emergency AD 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 on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
1023.

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. This 
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 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

FAA's Justification and Determination of the Effective Date

    We determined that AD 2017-19-17 contains an error in the 
description of follow-on actions that could allow the identified unsafe 
condition to continue for Model FALCON 2000EX airplanes. This AD 
corrects the follow-on actions for the Model FALCON 2000EX airplanes. 
No other changes have been made to AD 2017-19-17. Therefore, we 
determined that notice and opportunity for public comment before 
issuing this AD are unnecessary and that good cause exists for making 
this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2017-1023; Product 
Identifier 2017-NM-144-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 52 airplanes of U.S. registry.
    The action required by AD 2017-19-17, and retained in this AD, 
takes about 5 work-hours 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 2017-19-17 is $425 per product. This AD adds no 
new economic burden to AD 2017-19-17.
    We also estimate that any necessary follow-on actions will 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

[[Page 55034]]

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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.
