Airworthiness Directives; Dassault Aviation Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all
Dassault Aviation Model FALCON 2000EX airplanes. This AD requires
revising the airplane flight manual to include a procedure for
addressing minimum fan speed rotation (N1) values during stand-alone
engine anti-ice system operation for engines equipped with certain air
inlets. This AD was prompted by a quality review of recently delivered
airplanes which identified a manufacturing deficiency of some engine
air inlet anti-ice piccolo tubes. We are issuing this AD to detect and
correct reduced performance of the engine anti-ice protection system,
leading to ice accretion and ingestion into the engines, which could
result in dual engine power loss and consequent reduced controllability
of the airplane.

DATES: This AD becomes effective June 30, 2015.
We must receive comments on this AD by August 14, 2015.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:
Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions

SUPPLEMENTARY INFORMATION:

Discussion

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 2015-0102-E, dated June 8, 2015
(referred to after this as the Mandatory Continuing Airworthiness
Information, or ``the MCAI''), to correct an unsafe condition for all
Dassault Aviation Model FALCON 2000EX airplanes. The MCAI states:

A quality review of recently delivered aeroplanes identified a
manufacturing deficiency of some engine air inlet anti ice piccolo
tubes.
This condition, if not detected and corrected, could lead to
reduced performance of the engine anti-ice protection system, with
consequent ice accretion and ingestion, possibly resulting in dual
engine power loss and reduced control of an aeroplane.
The Falcon 2000EX Aircraft Flight Manual (AFM) contains a
procedure 4-200-05, ``Operations in Icing Conditions'', addressing
minimum fan speed rotation (N1) during combined operation of wing
anti-ice and engine anti-ice systems. However, the AFM does not
specify minimum N1 values for stand-alone engine anti-ice system
operation. The subsequent investigation demonstrated that the
operation of an engine at or above the minimum N1 value applicable
for combined wing and engine anti-ice operations, provides efficient
engine anti ice performance during stand-alone engine anti-ice
operation, for engines equipped with an air inlet affected by the
manufacturing deficiency.
For the reasons described above, this [EASA] AD requires
amendment of the applicable AFM which can be removed (or is not
applicable) for aeroplanes having both engine air inlet[s] marked
``NRK'' on the associated data plate.
This [EASA] AD is considered to be an interim measure and
further AD action may follow.

You may examine the MCAI on the Internet at http://www.regulations.gov
by searching for and locating Docket No. FAA-2015-1988.

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 the same
type design.

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because the
identified unsafe condition could result in engine inlet ice accretion
with possible ice separation in volumes beyond engine ingestion
capability. These conditions could lead to engine damage or engine
shutdown. Therefore, we determined that notice and opportunity for
public comment before issuing this AD are impracticable 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-2015-1988; Directorate
Identifier 2015-NM-085-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 based on
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 120 airplanes of U.S. registry.
We also estimate that it will take about 1 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Based on these figures, we estimate the cost of
this AD on U.S. operators to be $10,200, or $85 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.
