Discussion
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA Emergency AD
No. 2016–264–E, dated December 22,
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
31899
2016, to correct an unsafe condition for
Airbus Helicopters Model SA330J
helicopters. EASA advises of reports of
broken screws that attach the cover of
the hydraulic pump. A subsequent
investigation identified a batch of
screws delivered between July 1, 2015,
and November 1, 2016, that have
intrinsic embrittlement and reduced
mechanical properties. Hydrogen was
introduced into this batch of screws
during production, causing the screws
to become brittle and lack sufficient
strength. These screws were installed in
a batch of hydraulic pumps, part
number (P/N) FR65WEO2005–175A,
identified by certain serial numbers,
EASA advises.
This condition, if not detected and
corrected, could lead to the failure of a
cover bolt and loss of fluid from the
hydraulic pump, resulting in loss of the
hydraulic system and subsequent loss of
helicopter control. As a result, EASA
AD No. 2016–264–E requires replacing
the hydraulic pumps.
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.
Related Service Information
We reviewed Airbus Helicopters
Emergency Alert Service Bulletin No.
SA330–29.12, Revision 0, dated
December 22, 2016 (Airbus EASB), for
Model SA330J helicopters and military
model SA330L, SA330Jm, SA330S1,
and SA330Sm helicopters. The Airbus
EASB specifies removing Nexter
Mechanics hydraulic pumps P/N
FR65WEO2005–175A with certain serial
numbers. If both the right-hand (RH)
and left-hand (LH) hydraulic pumps
have an affected P/N and serial number,
the Airbus EASB specifies replacing the
RH hydraulic pump before further flight
and the LH hydraulic pump within 110
flying hours or 6 months. If only one
hydraulic pump has an affected P/N and
serial number, the Airbus EASB
specifies replacing it within 110 flying
hours or 6 months. The Airbus EASB
also specifies that, for 6 months after
receipt of the Airbus EASB, before
installing an affected hydraulic pump it
must be ‘‘returned to conformity’’ by
complying with Nexter Mechanics Alert

Revision 0, dated December 22, 2016
(Nexter ASB). After 6 months or 110
flying hours, whichever occurs first, the
Airbus EASB states the affected
hydraulic pumps are unfit for flight.
before issuing this AD are impracticable
and contrary to the public interest and
that good cause exists to make this AD
effective in less than 30 days.
AD Requirements
This AD requires, within 15 hours
time-in-service (TIS), removing the RH
hydraulic pump if both hydraulic
pumps are listed in the applicability
section of this AD. This AD also
prohibits installing an affected
hydraulic pump on any helicopter.
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.
Differences Between This AD and the
EASA AD
The EASA AD requires replacing the
LH hydraulic pump with a serviceable
part within 110 hours TIS or 6 months,
whichever comes first, if both the LH
and RH hydraulic pumps are affected
parts. The EASA AD also requires, if
only one hydraulic pump is an affected
part, replacing it with a serviceable part
within 110 hours TIS or 6 months,
whichever comes first. This AD makes
no such requirements. We are
considering requiring those actions.
However, the planned compliance time
for those actions would allow enough
time to provide notice and opportunity
for prior public comment. The EASA
AD allows a hydraulic pump to be
installed if it has been repaired in
accordance with the Nexter ASB, while
this AD does not.
mstockstill on DSK30JT082PROD with RULES
Costs of Compliance
We estimate that this AD affects 24
helicopters and that labor costs average
$85 per work-hour. Based on these
estimates, we expect that replacing a
hydraulic pump requires 2 work-hours
and parts cost $2,500 for a total cost of
$2,670 per helicopter and $64,080 for
the U.S. fleet.
FAA’s Justification and Determination
of the Effective Date
Providing an opportunity for public
comments prior to adopting these AD
requirements would delay
implementing the safety actions needed
to correct this known unsafe condition.
Therefore, we find that the risk to the
flying public justifies waiving notice
and comment prior to the adoption of
this rule because the required corrective
actions must be accomplished within 15
hours TIS, a very short time period
based on the typical utilization rate of
these helicopters in off-shore oil
operations.
Since an unsafe condition exists that
requires the immediate adoption of this
AD, we determined that notice and
opportunity for prior public comment

Authority for This Rulemaking
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, 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.

SUPPLEMENTARY INFORMATION:
Discussion
On January 5, 2017, at 82 FR 1260, 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
Airbus Helicopters Model AS332C,
AS332C1, AS332L, AS332L1, AS332L2,
and EC225LP helicopters with an IGB
fairing part number (P/N) 332A24–
0303–05XX, 332A24–0303–06XX,
PO 00000

Fmt 4700
Sfmt 4700
31901
332A08–1391–00, or 332A08–1391–01
installed, where ‘‘XX’’ is any two
alphanumeric characters. The NPRM
proposed to require repetitive
inspections of the IGB fairing. The
proposed requirements were intended to
prevent the detachment of the angle
section of an IGB and subsequent
interference between an IGB fairing and
tail rotor inclined drive shaft. This
condition could result in failure of a tail
rotor drive shaft, loss of the tail rotor
drive, and subsequent loss of control of
the helicopter.
The NPRM was prompted by AD No.
2015–0092, dated May 26, 2015, issued
by EASA, which is the Technical Agent
for the Member States of the European
Union, to correct an unsafe condition
for the Airbus Model AS332C,
AS332C1, AS332L, AS332L1, AS332L2,
and EC225LP helicopters with certain
part-numbered IGB fairings installed.
EASA advises of occurrences involving
separation of the angle section of the
IGB fairing from the IGB fairing gutter,
which caused interference with the tail
rotor (T/R) inclined drive shaft. EASA
states that this condition, if not detected
and corrected, could lead to failure of
the T/R drive shaft, loss of the T/R
drive, and consequent reduced control
of the helicopter. To address this
condition, EASA issued a series of ADs,
including AD No. 2015–0092, to require
repetitive inspections of the IGB fairing
and its attachment supports and
installation of a new IGB fairing, P/N
332A24–0322–00, as terminating action
for the inspections.
Comments
An individual commented that he
supports the NPRM.
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.
Differences Between This AD and the
EASA AD
The EASA AD requires replacing the
IGB fairing with the composite fairing
within 31 months. This AD requires this

investigation identified a batch of screws delivered between July 1,
2015, and November 1, 2016, that have intrinsic embrittlement and
reduced mechanical properties. Hydrogen was introduced into this batch
of screws during production, causing the screws to become brittle and
lack sufficient strength. These screws were installed in a batch of
hydraulic pumps, part number (P/N) FR65WEO2005-175A, identified by
certain serial numbers, EASA advises.
This condition, if not detected and corrected, could lead to the
failure of a cover bolt and loss of fluid from the hydraulic pump,
resulting in loss of the hydraulic system and subsequent loss of
helicopter control. As a result, EASA AD No. 2016-264-E requires
replacing the hydraulic pumps.
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.
Related Service Information
We reviewed Airbus Helicopters Emergency Alert Service Bulletin No.
SA330-29.12, Revision 0, dated December 22, 2016 (Airbus EASB), for
Model SA330J helicopters and military model SA330L, SA330Jm, SA330S1,
and SA330Sm helicopters. The Airbus EASB specifies removing Nexter
Mechanics hydraulic pumps P/N FR65WEO2005-175A with certain serial
numbers. If both the right-hand (RH) and left-hand (LH) hydraulic pumps
have an affected P/N and serial number, the Airbus EASB specifies
replacing the RH hydraulic pump before further flight and the LH
hydraulic pump within 110 flying hours or 6 months. If only one
hydraulic pump has an affected P/N and serial number, the Airbus EASB
specifies replacing it within 110 flying hours or 6 months. The Airbus
EASB also specifies that, for 6 months after receipt of the Airbus
EASB, before installing an affected hydraulic pump it must be
``returned to conformity'' by complying with Nexter Mechanics Alert
[[Page 31900]]
Service Bulletin No. NM/INGE/16-140, Revision 0, dated December 22,
2016 (Nexter ASB). After 6 months or 110 flying hours, whichever occurs
first, the Airbus EASB states the affected hydraulic pumps are unfit
for flight.
AD Requirements
This AD requires, within 15 hours time-in-service (TIS), removing
the RH hydraulic pump if both hydraulic pumps are listed in the
applicability section of this AD. This AD also prohibits installing an
affected hydraulic pump on any helicopter.
Differences Between This AD and the EASA AD
The EASA AD requires replacing the LH hydraulic pump with a
serviceable part within 110 hours TIS or 6 months, whichever comes
first, if both the LH and RH hydraulic pumps are affected parts. The
EASA AD also requires, if only one hydraulic pump is an affected part,
replacing it with a serviceable part within 110 hours TIS or 6 months,
whichever comes first. This AD makes no such requirements. We are
considering requiring those actions. However, the planned compliance
time for those actions would allow enough time to provide notice and
opportunity for prior public comment. The EASA AD allows a hydraulic
pump to be installed if it has been repaired in accordance with the
Nexter ASB, while this AD does not.
Costs of Compliance
We estimate that this AD affects 24 helicopters and that labor
costs average $85 per work-hour. Based on these estimates, we expect
that replacing a hydraulic pump requires 2 work-hours and parts cost
$2,500 for a total cost of $2,670 per helicopter and $64,080 for the
U.S. fleet.
FAA's Justification and Determination of the Effective Date
Providing an opportunity for public comments prior to adopting
these AD requirements would delay implementing the safety actions
needed to correct this known unsafe condition. Therefore, we find that
the risk to the flying public justifies waiving notice and comment
prior to the adoption of this rule because the required corrective
actions must be accomplished within 15 hours TIS, a very short time
period based on the typical utilization rate of these helicopters in
off-shore oil operations.
Since an unsafe condition exists that requires the immediate
adoption of this AD, we determined that notice and opportunity for
prior public comment before issuing this AD are impracticable and
contrary to the public interest and that good cause exists to make this
AD effective in less than 30 days.
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, 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.
