follows:
For the purposes of this AD, a detailed
inspection is an intensive examination of a
specific item, installation, or assembly to
detect damage, failure, or irregularity.
Available lighting is normally supplemented
with a direct source of good lighting at an
intensity deemed appropriate. Inspection
aids such as mirror, magnifying lenses, etc.,
may be necessary. Surface cleaning and
elaborate procedures may be required.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA AD 2017–
0017, dated February 1, 2017 (referred
to hereinafter as ‘‘the MCAI’’), to correct
an unsafe condition for the specified
products. The MCAI states:
Recently, a low speed abort (60 to 65 knots)
occurred on take-off on a Trent 1000powered Boeing 787 aeroplane. The pilot
performed a commanded engine shutdown
and the aeroplane safely returned to the gate.
Following investigation, failure and release
of the intermediate pressure compressor (IPC)
rotor seal was confirmed as having caused
this event. RR have confirmed that other IPC
rotor seals, Part Number (P/N) KH19098,
have been found with cracking at the seal
head. This condition, if not detected and
corrected, could lead to engine power loss,
possibly resulting in reduced control of the
aeroplane.
You may obtain further information
by examining the MCAI in the AD
docket on the Internet at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2017–
0187.
Related Service Information Under 1
CFR Part 51
RR has issued Alert Non-Modification
Service Bulletin (NMSB) Trent 1000 72–
AJ467, Revision 1, dated February 13,
2017; and NMSB Trent 1000 72–J353,
Revision 1, dated November 24, 2016.
The Alert NMSB describes procedures
for initial and repetitive inspections of
affected IPC rotor seal. The NMSB
describes procedures for in-shop
inspections of affected IPC rotor seals.
This service information is reasonably
available because the interested parties
have access to it through their normal
course of business or by the means
identified in the ADDRESSES section.
FAA’s Determination and Requirements
of This AD
This product has been approved by
EASA, and is approved for operation in
the United States. Pursuant to our
bilateral agreement with the European
Community, EASA has notified us of
the unsafe condition described in the
MCAI and service information
referenced above. 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
products of the same type design. This
AD requires initial and repetitive
inspections of affected IPC rotor seal for
cracks.
FAA’s Determination of the Effective
Date
No domestic operators use this
product. Therefore, we find that notice
and opportunity for prior public
comment are impracticable and that
good cause exists for making this
amendment effective in less than 30
days.
Costs of Compliance
We estimate that this AD affects 0
engines installed on airplanes of U.S.
registry.
We estimate the following costs to
comply with this AD:

Federal Register / Vol. 82, No. 127 / Wednesday, July 5, 2017 / Rules and Regulations
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 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),
(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.

ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for all
Airbus Model A319, A320, and A321
series airplanes. This AD was prompted
by a report that a main landing gear
(MLG) door could not be closed due to
rupture of the actuator fitting. This AD
requires repetitive inspections for
cracking of the MLG door actuator
fitting and its components, and
corrective actions if necessary. This AD
also requires eventual replacement of all
affected MLG door actuator fittings with
new monoblock fittings, which would
terminate the repetitive inspections. We
are issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective August 9,
2017.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of
proposed rulemaking (SNPRM) to
amend 14 CFR part 39 by adding an AD
that would apply to all Airbus Model
A319, A320, and A321 series airplanes.
The SNPRM published in the Federal
Register on April 7, 2017 (82 FR 16948)
(‘‘the SNPRM’’). We preceded the
SNPRM with a notice of proposed
rulemaking (NPRM) that published in
the Federal Register on January 28,
2016 (81 FR 4901) (‘‘the NPRM’’). The
NPRM proposed to require repetitive
inspections for cracking of the MLG
door actuator fitting and its
components, and corrective actions if
necessary. The NPRM also proposed to
require eventual replacement of all
affected MLG door actuator fittings with
new monoblock fittings, which would
terminate the repetitive inspections. The
NPRM was prompted by a report that an
MLG door could not be closed due to
rupture of the actuator fitting. The
SNPRM proposed to revise the NPRM
by reducing the compliance time for
replacing the MLG actuator fitting and
removing an inspection requirement for
certain airplanes. We are issuing this
PO 00000
Frm 00012
Fmt 4700
Sfmt 4700
AD to prevent rupture of the door
actuator fittings, which could result in
detachment of an MLG door and
subsequent exterior damage and
consequent reduced structural integrity
of the airplane.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA Airworthiness
Directive 2016–0182, dated September
13, 2016 (referred to after this as the
Mandatory Continuing Airworthiness
Information, or ‘‘the MCAI’’), to correct
an unsafe condition for all Airbus
Model A319, A320, and A321 series
airplanes. The MCAI states:
On one A320 aeroplane, it was reported
that one of the main landing gear (MLG)
doors could not be closed. Investigations
revealed the rupture of the actuator fitting at
the actuator attachment area on the door side.
The MLG door is attached to the aeroplane
by 2 (two) hinge fittings.
This condition, if not corrected, could,
under certain circumstances, lead to
detachment of a MLG door from the
aeroplane, possibly resulting in damage to
the aeroplane, and/or injury to persons on
the ground.
Prompted by these findings, [Direction
´ ´
Generale de l’Aviation Civile] France issued
* * * [an AD] * * *, to require a MLG door
actuator fitting inspection for cracks and to
check the grain direction on a batch of
aeroplanes. Subsequently, DGAC France
issued * * * [an AD], retaining the
requirements of DGAC France AD * * *,
which was superseded, to require an
inspection of the lower part of the MLG door
actuator fitting.
After that [DGAC] AD was issued,
additional investigations revealed that
damage could also appear on the nerve area
[of the forward monoblock fitting], in the
upper part of the MLG door actuator fitting
in the area of the hinge.
Consequently, DGAC France issued F–
2003–434, dated December 10, 2003 [https://
ad.easa.europa.eu/ad/F-2003-454] (EASA
approval 2003–1436), retaining the
requirements of [a] DGAC France AD * * *,
which was superseded, to require additional
repetitive inspections. That [DGAC] AD also
included an optional terminating action, by
replacing the MLG door actuator fittings in
accordance with the instructions of Airbus
Service Bulletin (SB) A320–52–1073.
After DGAC France AD F–2003–434 was
issued, in the framework of the extended
service goal campaign, it was decided to
make replacement of the MLG door actuator
fittings a required modification.
Consequently, EASA issued AD 2014–0166
* * *, retaining the requirements of DGAC
France AD F–2003–434, which was
superseded, and requiring replacement of the
MLG door actuator fittings with new
monoblock fittings, which constitutes
terminating action for the repetitive
inspections.
After EASA AD 2014–0166 [corresponding
to the NPRM] was issued, errors were
identified in the compliance time definitions.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD 2017-0017, dated February 1, 2017 (referred to hereinafter as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
Recently, a low speed abort (60 to 65 knots) occurred on take-
off on a Trent 1000-powered Boeing 787 aeroplane. The pilot
performed a commanded engine shutdown and the aeroplane safely
returned to the gate. Following investigation, failure and release
of the intermediate pressure compressor (IPC) rotor seal was
confirmed as having caused this event. RR have confirmed that other
IPC rotor seals, Part Number (P/N) KH19098, have been found with
cracking at the seal head. This condition, if not detected and
corrected, could lead to engine power loss, possibly resulting in
reduced control of the aeroplane.
You may obtain further information by examining the MCAI in the AD
docket on the Internet at https://www.regulations.gov by searching for
and locating Docket No. FAA-2017-0187.
Related Service Information Under 1 CFR Part 51
RR has issued Alert Non-Modification Service Bulletin (NMSB) Trent
1000 72-AJ467, Revision 1, dated February 13, 2017; and NMSB Trent 1000
72-J353, Revision 1, dated November 24, 2016. The Alert NMSB describes
procedures for initial and repetitive inspections of affected IPC rotor
seal. The NMSB describes procedures for in-shop inspections of affected
IPC rotor seals. This service information is reasonably available
because the interested parties have access to it through their normal
course of business or by the means identified in the ADDRESSES section.
FAA's Determination and Requirements of This AD
This product has been approved by EASA, and is approved for
operation in the United States. Pursuant to our bilateral agreement
with the European Community, EASA has notified us of the unsafe
condition described in the MCAI and service information referenced
above. 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 products of the same type design.
This AD requires initial and repetitive inspections of affected IPC
rotor seal for cracks.
FAA's Determination of the Effective Date
No domestic operators use this product. Therefore, we find that
notice and opportunity for prior public comment are impracticable and
that good cause exists for making this amendment effective in less than
30 days.
Costs of Compliance
We estimate that this AD affects 0 engines installed on airplanes
of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.

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 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),
(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.
