SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
E:\FR\FM\23JYR1.SGM
23JYR1
Federal Register / Vol. 83, No. 141 / Monday, July 23, 2018 / Rules and Regulations
Community, has issued EASA AD 2018–
0128, dated June 12, 2018 (referred to
hereinafter as ‘‘the MCAI’’), to address
an unsafe condition for the specified
products. The MCAI states:
Occurrences were reported on RR Trent
1000 ‘Pack B’ engines, where some IPC Rotor
1 and Rotor 2 blades were found cracked.
This condition, if not detected and
corrected, could lead to in-flight blade
release, possibly resulting in reduced control
of the aeroplane.
To address this potential unsafe condition,
RR issued the NMSB and the applicable
NMSB to provide instructions to inspect IPC
Rotor 1 blades, IPC Rotor 2 blades (front and
rear face) and IPC shaft Stage 2 dovetail
posts.
For the reason described above, this
[EASA] AD requires a one-time inspection of
the affected parts and, depending on the
findings, accomplishment of applicable
corrective action(s).
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–2018–
0590.
Related Service Information Under
1 CFR Part 51
We reviewed RR Alert NonModification Service Bulletin (NMSB)
Trent 1000 72–AK130, Initial Issue,
dated June 11, 2018. The NMSB
describes procedures for performing a
one-time inspection of the IPC stage 1
rotor blades, IPC stage 2 rotor blades,
and IPC stage 2 dovetail posts, and lists
engine serial numbers. 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.

relevant information provided by EASA
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
AD Requirements
This AD requires inspecting the IPC
stage 1 rotor blades, IPC stage 2 rotor
blades, and IPC stage 2 dovetail posts,
and removing any cracked parts from

SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2018–0129,
dated June 15, 2018 (referred to after
this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Airbus SAS Model A319–
115, –132, and –133 airplanes; and
Model A320–214, –216, –232, –233,
PO 00000
Frm 00009
Fmt 4700
Sfmt 4700
34761
–251N, and –271N airplanes. The MCAI
states:
Safety pins have been found installed on
the escape slide/slide raft inflation reservoir
on several aeroplanes. Investigations
determined that, on certain aeroplanes, safety
pins may not have been removed on the
production line.
This condition, if not detected and
corrected, would prevent the deployment of
the escape slide/slide raft, when required in
case of emergency, possibly resulting in
injury to the occupants.
To address this potential unsafe condition,
Airbus issued the original issue of the AOT
[alert operators transmission], providing
inspection instructions. The AOT has been
later revised twice to extend the
applicability.
For the reasons described above, this AD
requires a one-time inspection of each
affected slide/raft and, depending on
findings, removal of the safety pin.
You may examine the MCAI on the
internet at https://www.regulations.gov
by searching for and locating Docket No.
FAA–2018–0636.

SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European
[[Page 34759]]
Community, has issued EASA AD 2018-0128, dated June 12, 2018 (referred
to hereinafter as ``the MCAI''), to address an unsafe condition for the
specified products. The MCAI states:
Occurrences were reported on RR Trent 1000 `Pack B' engines,
where some IPC Rotor 1 and Rotor 2 blades were found cracked.
This condition, if not detected and corrected, could lead to in-
flight blade release, possibly resulting in reduced control of the
aeroplane.
To address this potential unsafe condition, RR issued the NMSB
and the applicable NMSB to provide instructions to inspect IPC Rotor
1 blades, IPC Rotor 2 blades (front and rear face) and IPC shaft
Stage 2 dovetail posts.
For the reason described above, this [EASA] AD requires a one-
time inspection of the affected parts and, depending on the
findings, accomplishment of applicable corrective action(s).
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-2018-0590.

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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to engines, propellers, and
associated appliances to the Manager, Engine and Propeller Standards
Branch, Policy and Innovation Division.
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
[[Page 34760]]
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, 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.
