AD was prompted by a loss of engine
power in flight caused by oil leaking
from the gearbox radial shaft sealing
ring that contaminated the clutch. This
proposed AD would require
replacement of the clutch with a dual
mass flywheel. We are proposing this
AD to correct the unsafe condition on
these products.

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–
0034, dated February 20, 2017 (referred
to hereinafter as ‘‘the MCAI’’), to correct
an unsafe condition for the specified
products.
The MCAI states:
A temporary power loss occurred during
flight on a TAE 125–02-powered aeroplane.
Following investigation, it was determined
that an improper lapping of the gearbox
driveshaft led to insufficient sealing of the
gearbox radial shaft sealing ring, eventually
resulting in oil leakage and oil contamination
of the clutch.
This condition, if not detected and
corrected, could lead to permanent 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–
0241.
Related Service Information Under 1
CFR Part 51
Technify Motors GmbH has issued
Service Bulletin (SB) No. SB TMG 125–
1020 P1, Initial Issue, dated January 27,
2016. The SB describes procedures for
replacing the clutch with a dual mass
flywheel. 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 Proposed AD
This product has been approved by
the aviation authority of Germany, 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 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 replacing
the clutch with a dual mass flywheel.
Costs of Compliance
We estimate that this proposed AD
affects 4 engines installed on airplanes
of U.S. registry.
We estimate the following costs to
comply with this proposed AD:

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
VerDate Sep<11>2014

Jkt 241001
Parts cost
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.

AGENCY:
We are revising an earlier
proposed airworthiness directive (AD)
that proposed to supersede AD 2011–
01–15, which applies to certain The
Boeing Company Model 757–200,
–200CB, and –300 series airplanes. AD
2011–01–15 requires repetitive
inspections for cracking of the fuselage
skin of the crown skin panel along the
chem-milled step at certain stringers,
and repair, if necessary. This action
revises the notice of proposed
rulemaking (NPRM) by reducing the
compliance time for certain inspections.
We are proposing this AD to address the
unsafe condition on these products.
Since these actions impose an
additional burden over that proposed in
the NPRM, we are reopening the
comment period to allow the public the
chance to comment on these proposed
changes.
DATES: We must receive comments on
this SNPRM by June 19, 2017.

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 Proposed AD
This product has been approved by the aviation authority of
Germany, 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 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 replacing the
clutch with a dual mass flywheel.
Costs of Compliance
We estimate that this proposed AD affects 4 engines installed on
airplanes of U.S. registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Replace clutch and gearbox............ 0 work-hours x $85 per $5,805 $5,805 $24,580
hour = $0.
----------------------------------------------------------------------------------------------------------------
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.
