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) 2015-02-04 for
certain Dassault Aviation Model MYSTERE-FALCON 50 airplanes. AD 2015-
02-04 required installing two protective plates between the electrical
wiring under the glare shield and the engine fire pull handles. This
new AD continues to require installing two protective plates between
the electrical wiring under the glare shield and the engine fire pull
handles. This AD was prompted by our determination that the published
version of AD 2015-02-04 incorrectly identified the AD number as ``AD
2014-02-04'' in a certain paragraph. We are issuing this AD to prevent
chafing of the electrical wiring, which could result in a short circuit
and generation of smoke in the cockpit, potential loss of several
functions essential for safe flight, and consequent reduced
controllability of the airplane.

DATES: This AD becomes effective April 29, 2015.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of March 6,
2015 (80 FR 5034, January 30, 2015).
We must receive comments on this AD by May 29, 2015.

SUPPLEMENTARY INFORMATION:

Discussion

On January 12, 2015, we issued AD 2015-02-04, Amendment 39-18071
(80 FR 5034, January 30, 2015). AD 2015-02-04 applied to certain Dassault
Aviation Model MYSTERE-FALCON 50 airplanes. AD 2015-02-04 was prompted
by a report of an untimely and intermittent indication of slat activity
due to chafing of the electrical wiring under the glare shield and
behind the flight deck front panel. AD 2015-02-04 required installing
two protective plates between the electrical wiring under the glare
shield and the engine fire pull handles. We issued AD 2015-02-04 to
prevent chafing of the electrical wiring, which could result in a short
circuit and generation of smoke in the cockpit, potential loss of
several functions essential for safe flight, and consequent reduced
controllability of the airplane.
AD 2015-02-04, Amendment 39-18071 (80 FR 5034, January 30, 2015),
corresponds to Mandatory Continuing Airworthiness Information (MCAI)
European Aviation Safety Agency (EASA) Airworthiness Directive 2014-
0024, dated January 23, 2014. You may examine the MCAI on the Internet
at http://www.regulations.gov by searching for and locating Docket No.
FAA-2015-0825.
Since we issued AD 2015-02-04, Amendment 39-18071 (80 FR 5034,
January 30, 2015), we have determined that the published version of AD
2015-02-04 incorrectly identified the AD number in the Product
Identification line as ``AD 2014-02-04.'' In order to refer to the
correct AD number, this AD replaces ``AD 2014-02-04'' with ``AD 2015-
02-04'' in the Product Identification line in the regulatory text.

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 of
the urgency to correct the AD number in the regulatory text to avoid
non-compliance. Therefore, we determined that notice and opportunity
for prior public comment are unnecessary.

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-2015-0825; Directorate
Identifier 2015-NM-035-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 250 airplanes of U.S. registry.
The actions required by AD 2015-02-04, Amendment 39-18071 (80 FR
5034, January 30, 2015), and retained in this AD are as follows:

This AD adds no additional economic burden.

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.
