SUMMARY: We are adopting a new airworthiness directive (AD) for certain
serial number (S/N) Lycoming Engines reciprocating engines. This AD was

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 S/N Lycoming
Engines reciprocating engines. The NPRM published in the Federal
Register on September 11, 2014 (79 FR 54218). The NPRM was prompted by
events of propeller governor shaft set screws coming loose due to
improper installation. If the set screws come loose, the engine may
lose oil resulting in damage to the engine and damage to the airplane.
The NPRM proposed to require application of Loctite 290, or equivalent,
to the threads of the propeller governor shaft set screw at each
installation of the set screw in addition to the peening of crankcase
hole threads. We are issuing this AD to prevent the propeller governor
shaft set screw from coming loose, causing damage to the engine and
damage to the airplane.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (79 FR 54218, September
11, 2014) or on the determination of the cost to the public.
We did however; find that we directed the use of LocTite 290, a
commercial product by brand name. We changed the AD to remove the
requirement to use any particular brand like LocTite 290, from this AD.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting this AD as proposed.
Related Service Information
We reviewed Lycoming Engines Service Instruction No. 1343B, dated
June 15, 2007. The service instruction describes procedures for
application of sealant for the propeller governor shaft set screw and
the peening of crankcase hole threads. You can find this information at
<a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No.
FAA-2014-0540.
Costs of Compliance
We estimate that this AD will affect about 2,330 engines installed
on airplanes of U.S. registry. We also estimate that it will take about
0.1 hours per engine to comply with this AD. The average labor rate is
$85 per hour. Prorated parts life will cost about $1 per engine. Based
on these figures, we estimate the cost of this AD on U.S. operators to
be $22,135.
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
[[Page 5906]]
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
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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under 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.
