two pipes of the emergency brake system #2
located near the nose landing gear bearing
The swapping of these two pipes implies
that when the Left Hand (LH) brake pedal is
depressed, the Right Hand (RH) brake unit is
activated, and conversely, when the RH brake
pedal is depressed, the LH brake unit is
actuated. This constitutes an unsafe
condition, which may go unnoticed as the
condition is latent until the emergency brake
system #2 is used. This condition, if not
corrected, could ultimately lead to a runway
excursion of the aeroplane.
For the reasons described above, this
[EASA] AD requires an [general visual]
inspection of the main landing gear braking
system and, in case of findings, proper re-
installation of the emergency brake system #2
pipes. This [EASA] AD also requires painting
the affected pipes for clear identification in
order to avoid mistakes while reinstalling
them after maintenance.

Relevant Service Information
DASSAULT AVIATION has issued
Service Bulletin F50-515, dated October
12, 2010. The actions described in this
service information are intended to
correct the unsafe condition identified
in the MCAI.
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
Differences Between the AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
We might also have required different
actions in this AD from those in the
MCAI in order to follow FAA policies.
Any such differences are highlighted in
a Note within the AD.
FAA's Determination of the Effective
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 this unsafe condition could
result in a high speed runway excursion
when the brakes are applied. 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
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-2010-1155;
Directorate Identifier 2010-NM-238-
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
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.
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
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
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 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); and
3. Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
