ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for
Eurocopter France EC130B4 helicopters.
This AD requires visually checking the
center windscreen panel (center
windscreen) for a crack and replacing
the center windscreen if there is a crack,
if the windscreen distorts during flight,
or within 12 months. This AD was
prompted by in-flight cracking and
failure of a center windscreen. The
actions of this AD are intended to detect
a crack in the blending radii of the
center windscreen to prevent failure of
the windscreen, injury to the flight
crew, and subsequent loss of control of
the helicopter.
DATES: This AD is effective May 15,
2013.
The Director of the Federal Register
approved the incorporation by reference
of a certain document listed in this AD

SUPPLEMENTARY INFORMATION:
Discussion
On June 18, 2012, at 77 FR 36213, the
Federal Register published our notice of
proposed rulemaking (NPRM), which
proposed to amend 14 CFR part 39 to
include an AD that would apply to
Eurocopter France EC130B4 helicopters
with a center windscreen, part number
(P/N) 350A25–9004–00, 350A25–9025–
00, or 350A25–9041–20. That NPRM
proposed to require, before each flight,
visually checking the center windscreen
and replacing the center windscreen
panel before further flight if there is a
crack in the center windscreen panel or
if the windscreen distorts during flight.
The NPRM also proposed to require,
within 12 months, replacing the center
windscreen with a certain partnumbered windscreen, which would
terminate the repetitive inspection
requirements. The NPRM specified that
an owner/operator (pilot) may perform
the visual check and must enter
compliance with the applicable
paragraph into the helicopter
maintenance records in accordance with
14 CFR 43.9(a)(1)–(4) and
91.417(a)(2)(v). A pilot may perform this
check because it involves only a visual
check for a crack in the center
windscreen and can be performed
equally well by a pilot or a mechanic.
This authorization is an exception to
our standard maintenance regulations.
The proposed requirements were
intended to detect a crack in the
blending radii of the center windscreen
to prevent failure of the windscreen,
PO 00000

injury to the flight crew, and subsequent
loss of control of the helicopter.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, issued EASA AD No. 2010–0258,
dated December 6, 2010 (AD 2010–
0258), to correct an unsafe condition for
the Eurocopter France EC130B4
helicopters. EASA received reports that
center windscreen panels failed during
flights due to a crack that started in the
blending radius between the lower and
upper sections of the windscreen. EASA
stated that this condition, if not detected
and corrected, could result in serious
injury of the helicopter occupants, and
therefore, issued Emergency AD 2007–
0219–E, dated August 24, 2007, (AD
2007–0219–E), requiring a pre-flight
inspection of the center windscreen,
repair or replacement of a cracked
windscreen, and an airspeed limitation.
In AD 2010–0258, EASA notes that it
approved a modification (MOD 073590)
for the EC130B4 helicopters that
incorporates a newly designed center
windscreen panel, part number (P/N)
350A25–9045–20, to ‘‘eliminate the
possibility of centre windshield cracks
thus providing an alternative
terminating action for the preflight
inspections.’’
Comments
We gave the public the opportunity to
participate in developing this AD, but
we received no comments on the NPRM
(77 FR 36213, June 18, 2012).
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 imposes flight
restrictions and replacing the
windscreen within 50 flight hours or 15
days, whichever occurs first, if
distortion of the windscreen is detected
in-flight. This AD mandates replacing
the windscreen before further flight if
distortion occurs during flight. In
addition, this AD mandates MOD
E:\FR\FM\10APR1.SGM
10APR1
21234
Federal Register / Vol. 78, No. 69 / Wednesday, April 10, 2013 / Rules and Regulations
073590 and replacing the affected
windscreen with an airworthy
windscreen, P/N 350A25–9045–20,
within 12 months.
Related Service Information
We reviewed Eurocopter Emergency
Alert Service Bulletin (ASB) No.
05A005 Revision 2, dated November 22,
2010. The ASB specifies:
• Performing a visual check of the
center windscreen before each flight.
• Replacing any center windscreen
before resuming flight if a crack is
detected.
• If in-flight distortion is found,
immediately restricting airspeed to 70
knots or below, and
Æ If a crack is found, before next
flight, replacing the windscreen per
Eurocopter Service Bulletin 56–003,
dated November 16, 2010, (SB 56–003),
which describes procedures to perform
MOD 073590, and
Æ If no crack is found, affixing an
airspeed limitation label and within 50
flying hours or 15 days, whichever is
earlier, replacing the windscreen per
MOD 073590.
• That incorporation of MOD 073590
is an alternative to the bulletin,
relieving users of the inspection
requirements.
EASA has classified this ASB as
mandatory and issued AD 2010–0258 to
ensure the continued airworthiness of
these helicopters.
Costs of Compliance
We estimate that this AD will affect
87 helicopters of U.S. registry and that
labor costs will average $85 per workhour. Therefore, we estimate the
following costs to comply with this AD:
• The check of the center windscreen
before each flight will take about 15
minutes for a labor cost of $21.25 per
inspection. No parts will be needed, so
the total cost for the U.S. 87-helicopter
fleet is about $1,849 per inspection.
• Replacing the center windscreen
will require about 20 work-hours for a
labor cost of $1,700 per helicopter. Parts
will cost $6,037 for a total cost per
helicopter of $7,737.
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.

ACTION: Final rule.
AGENCY:
We are superseding an
existing airworthiness directive (AD) for
certain The Boeing Company Model 757
airplanes equipped with Rolls-Royce
RB211–535E engines. That AD currently
requires repetitive inspections for signs
of damage of the aft hinge fittings and
attachment bolts of the thrust reversers,
and related investigative and corrective
actions if necessary. The existing AD
also provides for an optional
terminating modification for the
repetitive inspections. For certain
airplanes, this new AD adds a one-time
inspection of the washers installed
under the attachment bolts of the aft
hinge fittings for correct installation
sequence, and reinstallation if
necessary. This new AD also adds an
option for installing a redesigned aft
hinge fitting with the trim already done,
instead of trimming an existing or new
hinge fitting, which is included in the
existing optional terminating
modification. This AD was prompted by
reports of incorrectly installed washers
under the attachment bolts of the aft
hinge fittings of the thrust reversers. We
are issuing this AD to prevent failure of
the attachment bolts and consequent
separation of a thrust reverser from the
airplane during flight, which could
result in structural damage to the
airplane.

part 39 to supersede AD 2008–13–20,
Amendment 39–15583 (73 FR 37786,
July 2, 2008). That AD applies to the
specified products. The NPRM
published in the Federal Register
August 16, 2012 (77 FR 49396). That
NPRM proposed to continue to require
repetitive inspections for signs of
damage of the aft hinge fittings and
attachment bolts of the thrust reversers,
and related investigative and corrective
actions if necessary. That NPRM also
proposed to continue to provide for an
optional terminating modification for
the repetitive inspections. For certain
airplanes, that NPRM proposed to add a
one-time inspection of the washers
installed under the attachment bolts of
the aft hinge fittings for correct

installation sequence, and reinstallation
if necessary. That NPRM also proposed
to add an option for installing a

existing or new hinge fitting, which is
included in the existing optional
terminating modification.
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comments
received on the proposal (77 FR 49396,
August 16, 2012) and the FAA’s
response to each comment.
Support for the NPRM (77 FR 49396,
August 16, 2012)
Boeing concurred with the content of
the NPRM (77 FR 49396, August 16,
2012).
FedEx Express stated that it is
accomplishing the actions specified in
the NPRM (77 FR 49396, August 16,
2012), and determined that its regular
maintenance check schedule is not
adversely affected by the specified
actions.
Request To Address Effects of NPRM
(77 FR 49396, August 16, 2012) on
Winglets
Aviation Partners Boeing (APB) stated
that it has reviewed the NPRM (77 FR
49396, August 16, 2012), and Boeing
Special Attention Service Bulletin 757–
54–0049, Revision 1, dated September
23, 2009, and Revision 2, dated July 27,
2011; and Boeing Special Attention
Service Bulletin 757–54–0050, Revision
1, dated October 7, 2009, and Revision
2, dated July 27, 2011; and has
determined that the installation of
winglets, per Supplemental Type
Certificate (STC) ST01518SE, ‘‘does not
affect them.’’
We infer that APB means the
installation of these winglets does not
affect accomplishing the NPRM (77 FR
49396, August 16, 2012). We agree with
the commenter and have determined
that this AD should clarify the
procedures to address these APB
winglets. We have added a new
paragraph (c)(2) to this AD to state that
the installation of STC ST01518SE
(https://rgl.faa.gov/Regulatory_and

ability to accomplish the actions
required by this AD. For airplanes on
which STC ST01518SE is installed, a

SUMMARY: We are adopting a new airworthiness directive (AD) for
Eurocopter France EC130B4 helicopters. This AD requires visually
checking the center windscreen panel (center windscreen) for a crack
and replacing the center windscreen if there is a crack, if the
windscreen distorts during flight, or within 12 months. This AD was
prompted by in-flight cracking and failure of a center windscreen. The
actions of this AD are intended to detect a crack in the blending radii
of the center windscreen to prevent failure of the windscreen, injury
to the flight crew, and subsequent loss of control of the helicopter.

SUPPLEMENTARY INFORMATION:
Discussion
On June 18, 2012, at 77 FR 36213, the Federal Register published
our notice of proposed rulemaking (NPRM), which proposed to amend 14
CFR part 39 to include an AD that would apply to Eurocopter France
EC130B4 helicopters with a center windscreen, part number (P/N) 350A25-
9004-00, 350A25-9025-00, or 350A25-9041-20. That NPRM proposed to
require, before each flight, visually checking the center windscreen
and replacing the center windscreen panel before further flight if
there is a crack in the center windscreen panel or if the windscreen
distorts during flight. The NPRM also proposed to require, within 12
months, replacing the center windscreen with a certain part-numbered
windscreen, which would terminate the repetitive inspection
requirements. The NPRM specified that an owner/operator (pilot) may
perform the visual check and must enter compliance with the applicable
paragraph into the helicopter maintenance records in accordance with 14
CFR 43.9(a)(1)-(4) and 91.417(a)(2)(v). A pilot may perform this check
because it involves only a visual check for a crack in the center
windscreen and can be performed equally well by a pilot or a mechanic.
This authorization is an exception to our standard maintenance
regulations. The proposed requirements were intended to detect a crack
in the blending radii of the center windscreen to prevent failure of
the windscreen, injury to the flight crew, and subsequent loss of
control of the helicopter.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, issued EASA AD No.
2010-0258, dated December 6, 2010 (AD 2010-0258), to correct an unsafe
condition for the Eurocopter France EC130B4 helicopters. EASA received
reports that center windscreen panels failed during flights due to a
crack that started in the blending radius between the lower and upper
sections of the windscreen. EASA stated that this condition, if not
detected and corrected, could result in serious injury of the
helicopter occupants, and therefore, issued Emergency AD 2007-0219-E,
dated August 24, 2007, (AD 2007-0219-E), requiring a pre-flight
inspection of the center windscreen, repair or replacement of a cracked
windscreen, and an airspeed limitation. In AD 2010-0258, EASA notes
that it approved a modification (MOD 073590) for the EC130B4
helicopters that incorporates a newly designed center windscreen panel,
part number (P/N) 350A25-9045-20, to ``eliminate the possibility of
centre windshield cracks thus providing an alternative terminating
action for the preflight inspections.''
Comments
We gave the public the opportunity to participate in developing
this AD, but we received no comments on the NPRM (77 FR 36213, June 18,
2012).
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 imposes flight restrictions and replacing the
windscreen within 50 flight hours or 15 days, whichever occurs first,
if distortion of the windscreen is detected in-flight. This AD mandates
replacing the windscreen before further flight if distortion occurs
during flight. In addition, this AD mandates MOD
[[Page 21234]]
073590 and replacing the affected windscreen with an airworthy
windscreen, P/N 350A25-9045-20, within 12 months.
Related Service Information
We reviewed Eurocopter Emergency Alert Service Bulletin (ASB) No.
05A005 Revision 2, dated November 22, 2010. The ASB specifies:
Performing a visual check of the center windscreen before
each flight.
Replacing any center windscreen before resuming flight if
a crack is detected.
If in-flight distortion is found, immediately restricting
airspeed to 70 knots or below, and
[cir] If a crack is found, before next flight, replacing the
windscreen per Eurocopter Service Bulletin 56-003, dated November 16,
2010, (SB 56-003), which describes procedures to perform MOD 073590,
and
[cir] If no crack is found, affixing an airspeed limitation label
and within 50 flying hours or 15 days, whichever is earlier, replacing
the windscreen per MOD 073590.
That incorporation of MOD 073590 is an alternative to the
bulletin, relieving users of the inspection requirements.
EASA has classified this ASB as mandatory and issued AD 2010-0258
to ensure the continued airworthiness of these helicopters.
Costs of Compliance
We estimate that this AD will affect 87 helicopters of U.S.
registry and that labor costs will average $85 per work-hour.
Therefore, we estimate the following costs to comply with this AD:
The check of the center windscreen before each flight will
take about 15 minutes for a labor cost of $21.25 per inspection. No
parts will be needed, so the total cost for the U.S. 87-helicopter
fleet is about $1,849 per inspection.
Replacing the center windscreen will require about 20
work-hours for a labor cost of $1,700 per helicopter. Parts will cost
$6,037 for a total cost per helicopter of $7,737.
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.
