Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA AD 2014–
0168, dated July 16, 2014 (referred to
hereinafter as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
There have been nine occurrences of high oil
consumption, caused by fracture of the High/
Intermediate Pressure (HP/IP) turbine
support internal oil feed tube Part Number
(P/N) FW45909.
The oil feed tube threaded end adaptor and
sealing sleeve P/N FW15003 are designed to
form a sliding joint which, if restrained, can
compress the oil feed tube during thermal
contraction of the turbine casing at the end

Federal Register / Vol. 79, No. 181 / Thursday, September 18, 2014 / Proposed Rules
of the flight cycle. On each subsequent flight,
the thermal growth and contraction of the
turbine casing relative to the oil tube, during
the heating and cooling phases of the flight
cycle, apply a load cycle to the tube, which
may lead to low cycle fatigue fracture.
This AD requires removal of certain
HP/IP turbine support internal oil feed
tube sealing sleeves to prevent oil
exhaustion that could result in
uncontained engine failure and damage
to the airplane.
You may obtain further information
by examining the MCAI in the AD
docket on the Internet at https://

FAA’s Determination and Requirements
of This Proposed 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. We are proposing 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 proposed AD
would require a one-time on-wing or inshop inspection of the affected engines
and removal from service of all affected
P/N FW15003 oil feed tube sealing
sleeves.

Costs of Compliance
We estimate that this proposed AD
affects 69 engines installed on airplanes
of U.S. registry. We also estimate that it
would take about 8.5 hours per engine
to comply with this proposed AD. The
average labor rate is $85 per hour. Based
on these figures, we estimate the cost of
this proposed AD on U.S. operators to
be $49,853.
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
VerDate Sep<11>2014

Jkt 232001
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 proposed AD
would not have federalism implications
under Executive Order 13132. This
proposed AD would 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 proposed regulation:
(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.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD 2014-0168, dated July 16, 2014 (referred to hereinafter as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
There have been nine occurrences of high oil consumption, caused by
fracture of the High/Intermediate Pressure (HP/IP) turbine support
internal oil feed tube Part Number (P/N) FW45909.
The oil feed tube threaded end adaptor and sealing sleeve P/N
FW15003 are designed to form a sliding joint which, if restrained,
can compress the oil feed tube during thermal contraction of the
turbine casing at the end
[[Page 56026]]
of the flight cycle. On each subsequent flight, the thermal growth
and contraction of the turbine casing relative to the oil tube,
during the heating and cooling phases of the flight cycle, apply a
load cycle to the tube, which may lead to low cycle fatigue
fracture.
This AD requires removal of certain HP/IP turbine support internal
oil feed tube sealing sleeves to prevent oil exhaustion that could
result in uncontained engine failure and damage to the airplane.
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-2014-0561.
FAA's Determination and Requirements of This Proposed 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. We are
proposing 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 proposed AD
would require a one-time on-wing or in-shop inspection of the affected
engines and removal from service of all affected P/N FW15003 oil feed
tube sealing sleeves.
Costs of Compliance
We estimate that this proposed AD affects 69 engines installed on
airplanes of U.S. registry. We also estimate that it would take about
8.5 hours per engine to comply with this proposed AD. The average labor
rate is $85 per hour. Based on these figures, we estimate the cost of
this proposed AD on U.S. operators to be $49,853.
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
(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.
