an unsafe condition for the specified
products. The MCAI states:
Occurrences were reported involving high
engine vibration indication experienced
during climb. Subsequent investigation of
affected engines identified damage to some
high pressure turbine (HPT) blades. These
events have been attributed to cracks, which
originated at the tip of the leading edge, and
at the mid-height pressure surface, of the
HPT blades. Investigation also determined
that HPT blades Part Number (P/N) FW63853
(corresponding to RR Service Bulletin (SB)
SB 72–G275 modification standard) are
affected by this phenomenon. Four
occurrences have been reported within the
last two years.
This condition, if not detected and
corrected, could lead to high vibration
indication and commanded in-flight shutdown, 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–2016–

Discussion
FAA’s Determination and Requirements
of This AD
This product has been approved by
the aviation authority of the United
Kingdom, 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 HPT blades for
cracks.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA AD 2016–
0215, dated October 27, 2016 (referred
to hereinafter as ‘‘the MCAI’’), to correct

SUPPLEMENTARY INFORMATION:
The FAA’s authority to issue rules
regarding aviation safety is found in
Title 49 of the United States Code.
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. This rulemaking is
promulgated under the authority
described in Subtitle VII, Part A,
Subpart I, Section 40103. Under that
section, the FAA is charged with
prescribing regulations to assign the use
of airspace necessary to ensure the
safety of aircraft and the efficient use of
airspace. This regulation is within the
scope of that authority as it amends
controlled airspace at Batten
International Airport, Racine, WI, and
General Mitchell International Airport,
Milwaukee, WI.
History
The FAA was notified that John H.
Batten Airport, Racine, WI, has changed
its name to Batten International Airport,
Racine, WI. This is an administrative
change updating the name in the legal
description for the airport to match FAA
databases. The geographic coordinates
for General Mitchell International

Class E airspace designations are
published in paragraph 6005 of FAA
Order 7400.11A dated August 3, 2016,
and effective September 15, 2016, which
is incorporated by reference in 14 CFR
part 71.1. The Class E airspace
designations listed in this document
will be published subsequently in the
Order.
Availability and Summary of
Documents for Incorporation by
Reference
This document amends FAA Order
7400.11A, Airspace Designations and
Reporting Points, dated August 3, 2016,
and effective September 15, 2016. FAA
Order 7400.11A is publicly available as
listed in the ADDRESSES section of this
document. FAA Order 7400.11A lists
Class A, B, C, D, and E airspace areas,
air traffic service routes, and reporting
points.
The Rule
This action amends Title 14, Code of
Federal Regulations (14 CFR) part 71 by
updating the name of Batten
International Airport (formerly John H.
Batten Airport), Racine, WI, in the
regulatory text of the Class E airspace
extending upward from 700 feet or more
above the surface of the Earth at Batten
International Airport, Racine, WI. This
action also updates the geographic
coordinates of General Mitchell
International Airport, Milwaukee, WI, to
be in concert with the FAA’s
aeronautical database.
Section 553(b)(3)(B) of the
Administrative Procedures Act (5.
U.S.C.) authorizes agencies to dispense
with notice and comment procedure
when the agency for ‘‘good cause’’ finds
that these procedures are
‘‘impracticable, unnecessary, or contrary
to the public interest.’’ This is an
administrative change amending the
description for Batten International
Airport, and adjusts the geographic
coordinates for General Mitchell
International Airport, to be in concert
with the FAA’s aeronautical database
and does not affect the boundaries, or
operating requirements of the airspace;
therefore, notice and public procedure
under 5 U.S.C. 553(b) are unnecessary.
Regulatory Notices and Analyses
The FAA has determined that this
regulation only involves an established
body of technical regulations for which
frequent and routine amendments are
necessary to keep them operationally
current, is non-controversial and
unlikely to result in adverse or negative
comments. It, therefore: (1) Is not a

edge of the HPT blade. 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 the aviation authority of the
United Kingdom, 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 HPT blades 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 unnecessary and
that good
[[Page 11802]]
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.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection of the HPT blades.... 1.5 work-hours x $85 per $0 $127 $0 per inspection
hour = $127 per
inspection.

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.

deterioration resulting in operational disruptions. We are issuing
this AD to prevent HPT blade failure, loss of engine thrust control,
and reduced control of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(1) Perform an initial inspection of each HPT blade before
exceeding the following, whichever occurs later:
(i) 1,750 engine flight cycles (FCs) since new or 11,000 engine
flight hours (FHs) since new, whichever occurs first; or
(ii) 30 days after the effective date of this AD.
(2) Thereafter, perform repetitive inspections of the HPT blades
at intervals not to exceed 250 engine FCs or 1,125 engine FHs,
whichever occurs first.
(3) Use the Accomplishment Instructions, paragraph 3, of RR Non-
Modification Service Bulletin (NMSB) Trent 1000 72-J039, Revision 3,
dated October 14, 2016, to perform the inspections.
(4) If any crack is found during any inspection, follow the
applicable corrective action and reduced follow-on inspection
interval as defined in the Accomplishment Instructions, paragraph
3.A.(3), of RR NMSB Trent 1000 72-J039, Revision 3, dated October
14, 2016.
