above.
Novel or Unusual Design Features
Aircraft, Aviation safety, Reporting
and recordkeeping requirements.
The Airbus Model A350–900 series
will incorporate the following novel or
unusual design features: An electronic
flight control system that can affect how
the airplane responds to a roll
maneuver. This requires that the roll
maneuver result from defined
movements of the cockpit roll control as
opposed to defined aileron deflections.
This also requires an additional load
condition at VA, in which the cockpit
roll control is returned to neutral
following the initial roll input.
List of Subjects in 14 CFR Part 25
The authority citation for these
special conditions is as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701,
44702, 44704.
The Special Conditions
Accordingly, pursuant to the
authority delegated to me by the
Administrator, the following special
conditions are issued as part of the type
certification basis for Airbus Model
A350–900 series airplanes.
Discussion
1. Design Roll Maneuver Conditions
These proposed special conditions
differ from similar special conditions
applied on previous programs; and are
limited to the roll axis only, whereas
previous special conditions also
included the pitch and yaw axes.
Special conditions are no longer needed
for the pitch or yaw axes, because 14
CFR part 25 Amendment 25–91 takes
into account the effects of an electronic
flight control system in those axes
(§ 25.331 for pitch and § 25.351 for
yaw).
The following conditions, speeds, and
cockpit roll control motions (except as
the motions may be limited by pilot
effort) must be considered in
combination with an airplane load
factor of zero and of two-thirds of the
positive maneuvering factor used in
design. In determining the resulting
control surface deflections, the torsional
flexibility of the wing must be
considered in accordance with
§ 25.301(b):
a. Conditions corresponding to steady
rolling velocities must be investigated.
In addition, conditions corresponding to
maximum angular acceleration must be
investigated for airplanes with engines
or other weight concentrations outboard
of the fuselage. For the angular
acceleration conditions, zero rolling
velocity may be assumed in the absence
of a rational time history investigation
of the maneuver.
b. At VA, sudden movement of the
cockpit roll control up to the limit is
assumed. The position of the cockpit
roll control must be maintained until a
steady roll rate is achieved and then
must be returned suddenly to the
neutral position.
c. At VC, the cockpit roll control must
be moved suddenly and maintained so
as to achieve a roll rate not less than
that obtained in paragraph b.
d. At VD, the cockpit roll control must
be moved suddenly and maintained so
as to achieve a roll rate not less than
one-third of that obtained in paragraph
b.
Applicability
As discussed above, these special
conditions apply to Airbus Model
A350–900 series airplanes. Should
Airbus apply later for a change to the
type certificate to include another
model incorporating the same novel or
unusual design feature, the special
conditions would apply to that model as
well.

Conclusion
This action affects only certain novel
or unusual design features on the Airbus
Model A350–900 series airplanes. It is
not a rule of general applicability.
The substance of these special
conditions has been subjected to the
notice and comment period in several
prior instances and has been derived
without substantive change from those
previously issued. It is unlikely that
prior public comment would result in a
significant change from the substance
contained herein. Therefore, the FAA
has determined that prior public notice
and comment are unnecessary and
impracticable, and good cause exists for
adopting these special conditions upon
issuance. The FAA is requesting
comments to allow interested persons to
submit views that may not have been
submitted in response to the prior

SUPPLEMENTARY INFORMATION:
Discussion
On July 23, 2013, at 78 FR 44043, the
Federal Register published our notice of
proposed rulemaking (NPRM), which
proposed to amend 14 CFR part 39 by
adding an AD that would apply to
Eurocopter Model EC225LP helicopters
with an MRH assembly with a rotating
swashplate, part number (P/N) 332A31–
3074–00 or 332A31–3076–00, and
stationary swashplate, P/N 332A31–
3079–00 or 332A31–3079–01, installed.
The NPRM proposed to require
inspecting the swashplates for corrosion
or a crack, and making the appropriate
repairs or replacement of parts. The
proposed requirements were intended to
prevent failure of the swashplate and
subsequent loss of helicopter control.
The NPRM was prompted by AD No.
2012–0131, dated July 31, 2012, issued
by the European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, to correct an unsafe condition
for Eurocopter Model EC225LP
helicopters. EASA advises that
corrosion has been reported on the
rotating and stationary swashplates of
the MRH assembly of several
helicopters. This condition may cause
cracks on the swashplates, which may
cause failure of MRH parts and loss of
control of the helicopter. The EASA AD
requires repetitive inspections of the
affected swashplates after two years and
replacing the MRH assembly if a crack
is found.

Comments
We gave the public the opportunity to
participate in developing this AD, but
we received no comments on the NPRM
(78 FR 44043, July 23, 2013).
FAA’s Determination
These helicopters have been approved
by the aviation authority of France and
are approved for operation in the United
States. Pursuant to our bilateral
agreement with France, EASA, its
technical representative, has notified us
of the unsafe condition described in the
EASA AD. We are issuing this AD
because we evaluated all information
provided by EASA and determined the
unsafe condition exists and is likely to
exist or develop on other helicopters of
these same type designs and that air

safety and the public interest require
adopting the AD requirements as
proposed.
Related Service Information
We reviewed Eurocopter Alert Service
Bulletin No. EC225–05A030, Revision 0,
dated July 12, 2012 (ASB). The ASB
states that while reconditioning the
main rotor mast (MRM) assemblies,
Eurocopter found corrosion on the
rotating and stationary swashplates
under the retaining flanges of the
swashplate sub-assembly bearing. Over
time, this corrosion could initiate a
crack. The ASB specifies inspecting the
MRM assembly for corrosion or a crack
and replacing the MRM assembly if a
crack or corrosion is found. The FAA
and EASA use the term MRH assembly,
while Eurocopter uses MRM assembly
to describe the same section of the
helicopter.
Costs of Compliance
We estimate that this AD affects three
helicopters of U.S. Registry and that
labor costs average $85 per work-hour.
Based on these estimates, we expect the
following costs:
• Inspecting the rotating and
stationary swashplates for corrosion or a
crack requires 8 work-hours for a cost of
$680 per helicopter and $2,040 for the
U.S. fleet, per inspection cycle. Making
and installing the placard requires 0.5
work-hour, for a cost of $43 per
helicopter. The labor cost of making
changes to the flight manual is
negligible.
• Replacing the MRH assembly
requires 24 work-hours and parts cost
$5,000, for a total cost of $7,040 per
helicopter.
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
helicopters identified in this rulemaking
action.

Regulatory Findings
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
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979);
(3) Will not affect intrastate aviation
in Alaska to the extent that it justifies
making a regulatory distinction; 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.
We prepared an economic evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION: This
amendment to part 95 of the Federal
Aviation Regulations (14 CFR part 95)
amends, suspends, or revokes IFR
altitudes governing the operation of all
aircraft in flight over a specified route
or any portion of that route, as well as
the changeover points (COPs) for
Federal airways, jet routes, or direct
routes as prescribed in part 95.
The Rule
The specified IFR altitudes, when
used in conjunction with the prescribed
changeover points for those routes,
ensure navigation aid coverage that is
adequate for safe flight operations and
free of frequency interference. The
reasons and circumstances that create
the need for this amendment involve
matters of flight safety and operational
efficiency in the National Airspace
System, are related to published
aeronautical charts that are essential to
the user, and provide for the safe and
efficient use of the navigable airspace.
In addition, those various reasons or
circumstances require making this
amendment effective before the next
scheduled charting and publication date
of the flight information to assure its
timely availability to the user. The
effective date of this amendment reflects
those considerations. In view of the
close and immediate relationship
between these regulatory changes and
safety in air commerce, I find that notice
and public procedure before adopting
this amendment are impracticable and
contrary to the public interest and that
good cause exists for making the
amendment effective in less than 30
days.
Conclusion
The FAA has determined that this
regulation only involves an established
body of technical regulations for which
frequent and routine amendments are
necessary to keep them operationally
current. It, therefore—(1) is not a
‘‘significant regulatory action’’ under

SUPPLEMENTARY INFORMATION:
Discussion
On July 23, 2013, at 78 FR 44043, the Federal Register published
our notice of proposed rulemaking (NPRM), which proposed to amend 14
CFR part 39 by adding an AD that would apply to Eurocopter Model
EC225LP helicopters with an MRH assembly with a rotating swashplate,
part number (P/N) 332A31-3074-00 or 332A31-3076-00, and stationary
swashplate, P/N 332A31-3079-00 or 332A31-3079-01, installed. The NPRM
proposed to require inspecting the swashplates for corrosion or a
crack, and making the appropriate repairs or replacement of parts. The
proposed requirements were intended to prevent failure of the
swashplate and subsequent loss of helicopter control.
The NPRM was prompted by AD No. 2012-0131, dated July 31, 2012,
issued by the European Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union, to correct
an unsafe condition for Eurocopter Model EC225LP helicopters. EASA
advises that corrosion has been reported on the rotating and stationary
swashplates of the MRH assembly of several helicopters. This condition
may cause cracks on the swashplates, which may cause failure of MRH
parts and loss of control of the helicopter. The EASA AD requires
repetitive inspections of the affected swashplates after two years and
replacing the MRH assembly if a crack is found.
Comments
We gave the public the opportunity to participate in developing
this AD, but we received no comments on the NPRM (78 FR 44043, July 23,
2013).
FAA's Determination
These helicopters have been approved by the aviation authority of
France and are approved for operation in the United States. Pursuant to
our bilateral agreement with France, EASA, its technical
representative, has notified us of the unsafe condition described in
the EASA AD. We are issuing this AD because we evaluated all
information provided by EASA and determined the unsafe condition exists
and is likely to exist or develop on other helicopters of these same
type designs and that air safety and the public interest require
adopting the AD requirements as proposed.
Related Service Information
We reviewed Eurocopter Alert Service Bulletin No. EC225-05A030,
Revision 0, dated July 12, 2012 (ASB). The ASB states that while
reconditioning the main rotor mast (MRM) assemblies, Eurocopter found
corrosion on the rotating and stationary swashplates under the
retaining flanges of the swashplate sub-assembly bearing. Over time,
this corrosion could initiate a crack. The ASB specifies inspecting the
MRM assembly for corrosion or a crack and replacing the MRM assembly if
a crack or corrosion is found. The FAA and EASA use the term MRH
assembly, while Eurocopter uses MRM assembly to describe the same
section of the helicopter.
Costs of Compliance
We estimate that this AD affects three helicopters of U.S. Registry
and that labor costs average $85 per work-hour. Based on these
estimates, we expect the following costs:
Inspecting the rotating and stationary swashplates for
corrosion or a crack requires 8 work-hours for a cost of $680 per
helicopter and $2,040 for the U.S. fleet, per inspection cycle. Making
and installing the placard requires 0.5 work-hour, for a cost of $43
per helicopter. The labor cost of making changes to the flight manual
is negligible.
Replacing the MRH assembly requires 24 work-hours and
parts cost $5,000, for a total cost of $7,040 per helicopter.
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 helicopters identified in this
rulemaking action.
Regulatory Findings
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 DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979);
(3) Will not affect intrastate aviation in Alaska to the extent
that it justifies making a regulatory distinction; 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.
We prepared an economic evaluation of the estimated costs to comply
with this AD and placed it in the AD docket.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2013-26-11 Eurocopter France Helicopters (Eurocopter): Amendment 39-
17720; Docket No. FAA-2013-0635; Directorate Identifier 2012-SW-081-
AD.
(a) Applicability
This AD applies to Eurocopter Model EC225LP helicopters with a
main rotor hub (MRH) assembly with a rotating swashplate, part
number (P/N) 332A31-3074-00 or 332A31-3076-00, and stationary
swashplate, P/N 332A31-3079-00 or 332A31-3079-01, installed,
certificated in any category.
(b) Unsafe Condition
This AD defines the unsafe condition as corrosion or a crack in
the stationary or rotating swashplate of the MRH assembly, which
could lead to failure of the swashplate and subsequent loss of
helicopter control.
[[Page 2368]]
(c) Effective Date
This AD becomes effective February 18, 2014.
(d) Compliance
You are responsible for performing each action required by this
AD within the specified compliance time unless it has already been
accomplished prior to that time.
(e) Required Actions
(1) Within 110 hours time-in-service (TIS) or before the MRH
assembly accumulates 1,320 hours TIS, whichever occurs later, and
thereafter at intervals not to exceed 1,320 hours TIS, visually
inspect the rotating and stationary swashplates for corrosion or a
crack by following the Accomplishment Instructions, paragraph 3.B.2
and Figures 1 through 3, of Eurocopter Alert Service Bulletin No.
EC225-05A030, Revision 0, dated July 12, 2012 (ASB).
(2) If a crack exists in the rotating or stationary swashplates,
replace the MRH assembly with an airworthy MRH assembly.
(3) If corrosion exists without any visual indication of
cracking, do the following:
(i) Before further flight, install a placard stating ``NO FLIGHT
IN OAT BELOW -30 [deg]C'' in the full view of the pilots and add the
statement ``NO FLIGHT IN OAT BELOW -30 [deg]C'' to the Operating
Limitations Section of the helicopter's Rotorcraft Flight Manual
(RFM) by making pen and ink changes or by inserting a copy of this
AD in Section 2.3 Flight Envelope, Item 2 Temperature Limits.
(ii) Within 150 hours TIS or 6 months after the inspection when
the corrosion was first detected, whichever occurs first, replace
the MRH assembly with an airworthy assembly. Remove any placard that
states ``NO FLIGHT IN OAT BELOW -30 [deg]C'' from the helicopter and
remove any related limitation from the RFM.
(4) Replacement of an MRH assembly does not constitute
terminating action for the repetitive inspections required by
paragraph (e)(1) of this AD.
