Airworthiness Directives; Airbus Helicopters (Type Certificate
Previously Held by Eurocopter France) (Airbus Helicopters)
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding Airworthiness Directive (AD) 2012-25-04 for
Eurocopter France Model AS350B3 helicopters with a certain modification
(MOD) installed. AD 2012-25-04 required installing two placards and
revising the Rotorcraft Flight Manual (RFM). AD 2012-25-04 also
required certain checks and inspecting and replacing, if necessary, all
four laminated half-bearings (bearings). This new AD retains the
previous AD requirements, requires certain modifications which would be
terminating action for the airspeed limitations, and adds certain
helicopter models to the bearing inspection with a different inspection
interval. These actions are intended to prevent vibration due to a
failed bearing, failure of the tail rotor, and subsequent loss of
control of the helicopter.
DATES: This AD is effective May 2, 2014.
The Director of the Federal Register approved the incorporation by
reference of certain documents listed in this AD as of May 2, 2014.

SUPPLEMENTARY INFORMATION:
Discussion
On September 23, 2013, at 78 FR 58256, the Federal Register
published our notice of proposed rulemaking (NPRM), which proposed to
amend 14 CFR part 39 by removing AD 2012-25-04, Amendment 39-17285 (78
FR 24041, April 24, 2013) and adding an AD that would apply to
Eurocopter France (now Airbus Helicopters) Model AS350B, AS350BA,
AS350B1, AS350B2, AS350B3 (except AS350B3 helicopters with modification
(MOD) 07 5606 installed), AS350C, AS350D, AS350D1, AS355E, AS355F,
AS355F1, AS355F2, AS355N, and AS355NP helicopters. For Model AS350B3
helicopters with MOD 07 5601 installed, the NPRM proposed to require
limiting the velocity never exceed speed by installing a placard and
revising the RFM, checking the bearings after each flight for
separation, a crack, or extrusion, performing a one-time inspection of
the bearings, modifying the chin weight support and replacing any
bearings with more than 5 hours time-in-service (TIS), removing the
additional chin weights and installing blanks, modifying the rotating
pitch-change spider assembly, installing a load compensator, and
modifying the electrical installation. After modifying the helicopter,
the NPRM proposed to require removing the RFM limitations and placards
installed previously. For Model AS350B, AS350BA, AS350B1, AS350B2,
AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N,
AS355NP helicopters, and Model AS350B3 helicopters that do not have MOD
07 5601 installed, the NPRM also proposed to require checking the
bearings after the last flight of each day and replacing the bearings
if there is an extrusion, a crack, or separation. The proposed
requirements were intended to prevent vibration due to a failed
bearing, failure of the tail rotor, and subsequent loss of control of
the helicopter.
The NPRM was prompted by Emergency AD No. 2012-0257-E, dated
December 5, 2012 (EAD 2012-0257-E) issued by the European Aviation
Safety Agency (EASA), which is the Technical Agent for the Member
States of the European Union. EASA EAD 2012-0257-E advises of premature
failures of bearings on AS350B3 helicopters, and states that the
criticality of the bearing failures should apply to all AS355 and AS350
helicopters. As a result, EAD 2012-0257-E requires repetitive post-
flight checks of the bearings.
EASA then superseded EAD 2012-0217-E with EASA AD No. 2013-0029,
dated February 8, 2013 (AD 2013-0029), to correct an unsafe condition
for Eurocopter Model AS 350 B3 helicopters modified by MOD 07 5601,
except for helicopters modified by MOD 07 5606 in production. EASA
advises that MOD 07 5606 restores the tail rotor dynamic load level to
that on helicopters before installation of MOD 07 5601 and eliminates
the modified loading conditions of bearings which caused the
intensified deterioration and reported failures. For these reasons,
EASA AD 2013-0029 requires incorporation of MOD 07 5606 as a
terminating action.
Since we issued the NPRM, Eurocopter France has changed its name to
Airbus Helicopters. This AD reflects that change and updates the
contact information to obtain service documentation.
Comments
We gave the public the opportunity to participate in developing
this AD, but we did not receive any comments on the NPRM (78 FR 58256,
September 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 helicopter of these same
type designs and that air safety and the public interest require
adopting the AD requirements as proposed, except for the minor change
previously described and formatting changes. These changes are
consistent with the intent of the proposals in the NPRM (78 FR 58256,
September 23, 2013) and will not increase the economic burden on any
operator nor increase the scope of the AD.
Differences Between This AD and the EASA AD
The EASA AD requires removing the placard and RFM changes with the
true airspeed limitation (TAS) and replacing it with an indicated
airspeed limitation. Since AD 2012-25-04 did not include the TAS
limitation, this AD does not require removing it.
Related Service Information
We reviewed Eurocopter Service Bulletin (SB) No. AS350-01.00.66,
Revision 1, dated February 15, 2013 (SB AS350-01.00.66), which
describes procedures for removing the additional chin weights installed
on the tail rotor, installing a load compensator, and modifying the
electrical system installation, to reduce the dynamic loads on the tail
rotor. Eurocopter refers to the procedures in this SB as MOD 07 5606.
SB AS350-01.00.66 only applies to helicopters with MOD 07 5601
installed.
We reviewed one Eurocopter Emergency Alert Service Bulletin (EASB)
with two numbers: No. 01.00.65 for the Model AS350B3 helicopters and
No. 01.00.24 for the non-FAA type certificated Model AS550C3
helicopters (EASB 01.00.65). EASB 01.00.65 is Revision 3, dated
February 4, 2013. EASB 01.00.65 specifies installing a placard on the
instrument panel and revising the RFM to limit airspeed to 100 knots
IAS, revising the RFM to include a procedure in case of in-flight
vibrations originating in the tail rotor and an ``engine health
check,'' checking the bearings after each flight, and performing a one-
time inspection of the bearings. EASB 01.00.65 does not apply to
helicopters with MOD 07 5606 installed.
We also reviewed one Eurocopter EASB with four numbers: No 05.00.71
for Model AS350B, BA, BB, D, B1, B2, B3, and the non-FAA type
certificated L1 helicopters; No. 05.00.63 for Model AS355E, F, F1, F2,
N, and NP helicopters; No. 05.00.46 for the non-FAA type certificated
Model AS550A2, C2, C3, and U2 helicopters; and No. 05.00.42 for the
non-FAA type certificated Model AS555AF, AN, SN, UF, and UN helicopters
(EASB 05.00.71). EASB 05.00.71 is Revision 2, dated December 19, 2012.
EASB 05.00.71 specifies procedures for checking the bearings for
deterioration or damage after the last flight of each day. EASB
05.00.71 does not apply to helicopters with MOD 07 5601 installed.
[[Page 17410]]
We also reviewed Eurocopter SB No. AS350-64.00.11, Revision 0,
dated December 19, 2012 (SB AS350-64.00.11), which describes procedures
for modifying the tail rotor chin weight support to prevent
interference with the bearings. The manufacturer refers to the
procedures in this SB as MOD 07 6604. SB AS350-64.00.11 only applies to
helicopters with MOD 07 5601 installed.
Costs of Compliance
We estimate that the pilot checks of the bearings in this AD will
affect 938 helicopters of U.S. Registry, and that 50 helicopters will
be affected by the remaining requirements. The cost for the pilot
checks is minimal.
We estimate that operators may incur the following costs in order
to comply with this AD. At an average labor rate of $85 per hour,
installing a placard and revising the RFM requires about .5 work-hour,
for a cost per helicopter of $43 and a total cost to U.S. operators of
$2,150. Disassembling and inspecting the bearings requires about 6
work-hours, for a cost per helicopter of $510 and a total cost to U.S.
operators of $25,500. Modifying the chin weight support requires about
8 work-hours, for a cost per helicopter of $680, and a total cost to
U.S. operators of $34,000. Removing the additional chin weights
installed on the tail rotor, modifying the rotating pitch-change spider
assembly, installing a load compensator, and modifying the electrical
system installation requires about 200 work-hours, and required parts
will cost $18,343, for a cost per helicopter of $35,343, and a total
cost to U.S. operators of $1,767,150.
If necessary, replacing the bearings installed on the aircraft
requires about 6 work-hours, at an average labor rate of $85, and
required parts will cost $2,415, for a cost per helicopter of $2,925.
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 have 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 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.
