engines due to a quality control
deficiency in the manufacturing process
of certain valve push-rod assemblies
resulting in partial wear on the rocker
arm ball socket and possible
malfunction of the valve. This AD
requires one-time inspection and,
depending on the findings, replacement
of the affected parts with parts eligible
for installation. We are issuing this AD
to address the unsafe condition on these

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain Rotax 912 and 914
model engines. The NPRM published in
the Federal Register on November 6,
2018 (83 FR 55502). The NPRM was
prompted by power loss and engine
RPM drop on certain Rotax 912 and 914
model engines due to a quality control
deficiency in the manufacturing process
of certain valve push-rod assemblies
resulting in partial wear on the rocker
arm ball socket and possible
malfunction of the valve. The NPRM
proposed to require a one-time
inspection and, depending on the
findings, replacement of the affected
parts with parts eligible for installation.
We are issuing this AD to address the
unsafe condition on these products.
The European Union Aviation Safety
Agency (EASA), which is the Technical
Agent for the Member States of the
European Community, has issued EASA
AD 2017–0208, dated October 13, 2017
(referred to after this as ‘‘the MCAI’’), to
address the unsafe condition on these
products. The MCAI states:
Power loss and engine RPM drop have
been reported on Rotax 912/914 engines in
service. It has been determined that, due to
a quality control deficiency in the
manufacturing process of certain valve pushrod assemblies, manufactured between 08
June 2016 and 02 October 2017 inclusive,
partial wear on the rocker arm ball socket
E:\FR\FM\05JNR1.SGM
05JNR1
Federal Register / Vol. 84, No. 108 / Wednesday, June 5, 2019 / Rules and Regulations
may occur, which may lead to malfunction
of the valve train.
This condition, if not detected and
corrected, may lead to rough engine
operation and loss of power, possibly
resulting in a forced landing, with
consequent damage to the aeroplane and
injury to occupants.
Revision to Applicability Section
We revised paragraph (c)(4), in the
Applicability section of this AD, to refer
to ‘‘Rotax 912 F2, 912 F3, 912 F4, 912
S2, 912 S3, 912 S4, 914 F2, 914 F3, and
914 F4 engines (all S/Ns) on which a
valve push-rod assembly has been
replaced with one manufactured
between June 8, 2016, and October 2,
2017,’’ rather than ‘‘Rotax 912 F2, 912
F3, 912 F4, 912 S2, 912 S3, 912 S4, 914
F2, 914 F3, and 914 F4 engines (all
S/Ns) on which a valve push-rod
assembly has been replaced between
June 8, 2016, and the effective date of
this AD,’’ as proposed in the NPRM.
This change clarifies the applicability
and is consistent with the MCAI and
with Rotax Service Bulletin (SB) SB–912
i-008 R1/SB–912–070 R1/SB–914–052
R1 (single document), Revision 1, dated
October 12, 2017. Our proposed
wording would have unnecessarily
extended the applicability of this AD to
all valve push-rod assemblies that were
replaced on the affected Rotax engines
from October 2, 2017 until the effective
date of this AD.
Comments
We gave the public the opportunity to
participate in developing this final rule.
We received no comments on the NPRM
or on the determination of the cost to
the public.
Conclusion
We reviewed the relevant data and
determined that air safety and the
public interest require adopting this
final rule as proposed—except for minor
editorial changes and the changes to the
Applicability section discussed above.
We have determined that these minor
changes:
• Are consistent with the intent that
was proposed in the NPRM for
addressing the unsafe condition; and
25985
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
We reviewed Rotax SB SB–912 i-008
R1/SB–912–070 R1/SB–914–052 R1
(single document), Revision 1, dated
October 12, 2017. The SB describes
procedures for inspection and
replacement of the valve push-rod
assembly and the left and right rocker
arms. 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.
Costs of Compliance
We estimate that this AD affects 150
engines installed on airplanes of U.S.
registry.
We estimate the following costs to
comply with this 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

Parts cost
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.

control deficiency in the manufacturing process of certain valve push-
rod assemblies resulting in partial wear on the rocker arm ball socket
and possible malfunction of the valve. The NPRM proposed to require a
one-time inspection and, depending on the findings, replacement of the
affected parts with parts eligible for installation. We are issuing
this AD to address the unsafe condition on these products.
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Community, has
issued EASA AD 2017-0208, dated October 13, 2017 (referred to after
this as ``the MCAI''), to address the unsafe condition on these
products. The MCAI states:
Power loss and engine RPM drop have been reported on Rotax 912/
914 engines in service. It has been determined that, due to a
quality control deficiency in the manufacturing process of certain
valve push-rod assemblies, manufactured between 08 June 2016 and 02
October 2017 inclusive, partial wear on the rocker arm ball socket
[[Page 25985]]
may occur, which may lead to malfunction of the valve train.
This condition, if not detected and corrected, may lead to rough
engine operation and loss of power, possibly resulting in a forced
landing, with consequent damage to the aeroplane and injury to
occupants.
Revision to Applicability Section
We revised paragraph (c)(4), in the Applicability section of this
AD, to refer to ``Rotax 912 F2, 912 F3, 912 F4, 912 S2, 912 S3, 912 S4,
914 F2, 914 F3, and 914 F4 engines (all S/Ns) on which a valve push-rod
assembly has been replaced with one manufactured between June 8, 2016,
and October 2, 2017,'' rather than ``Rotax 912 F2, 912 F3, 912 F4, 912
S2, 912 S3, 912 S4, 914 F2, 914 F3, and 914 F4 engines (all S/Ns) on
which a valve push-rod assembly has been replaced between June 8, 2016,
and the effective date of this AD,'' as proposed in the NPRM. This
change clarifies the applicability and is consistent with the MCAI and
with Rotax Service Bulletin (SB) SB-912 i-008 R1/SB-912-070 R1/SB-914-
052 R1 (single document), Revision 1, dated October 12, 2017. Our
proposed wording would have unnecessarily extended the applicability of
this AD to all valve push-rod assemblies that were replaced on the
affected Rotax engines from October 2, 2017 until the effective date of
this AD.
Comments
We gave the public the opportunity to participate in developing
this final rule. We received no comments on the NPRM or on the
determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting this final rule as proposed--
except for minor editorial changes and the changes to the Applicability
section discussed above. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

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 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),
[[Page 25986]]
(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.
