SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2011-26-04, Amendment 39-16894 (76 FR 79051,
December 21, 2011), (``AD 2011-26-04''). AD 2011-26-04 applied to
certain fuel injected reciprocating engines manufactured by Lycoming
Engines. The NPRM published in the Federal Register on November 25,
2013 (78 FR 70240). The NPRM was prompted by revised service
information that added engine models to the applicability. The NPRM
proposed to expand the scope by adding the IO-540-C1C5 and IO-540-D4B5
engine models and requiring inspection, replacement if necessary, and
proper clamping of externally mounted fuel injector fuel lines. We are
issuing this AD to prevent failure of the fuel injector fuel lines,
which could lead to uncontrolled engine fire, engine damage, and damage
to the airplane.
Related Service Information Under 1 CFR Part 51
We reviewed Lycoming Engines Mandatory Service Bulletin (MSB) No.
342G, dated July 16, 2013; Supplement No. 1 to MSB No. 342G, dated
August 29, 2013; and Supplement No. 2 to MSB No. 342G, dated January
23, 2014. The service information describes procedures for fuel line
and support clamp inspection and installation. 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 of this AD.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments
received on the proposal and the FAA's response to each comment.
Request To Add an Engine Model
Aerotech Publications and an individual commenter requested that
the Lycoming LIO-360-M1A be added to the AD. The justification given
was that the type certificate data sheet, 1E10, shows the LIO-360-M1A
to be identical to the IO-360-M1A except with counter rotation.
Additionally, unless specific engine models are listed in the AD,
exempting those engines with maintenance manuals would prevent the
maintenance technician from knowing which engines are exempt.
We disagree. The engine certification basis determines if an engine
model's mandatory maintenance will be managed by a dedicated engine
maintenance manual (EMM) with an airworthiness limitations section
(ALS) or by manufacturer's service bulletins (SBs). Engines certified
to 14 CFR 33, as was LIO-360-M1A, have a dedicated EMM with an ALS that
includes the fuel tube inspection in Section 05-00-00. We did not
change this AD.
Request To Add Service Information
Lycoming Engines requested that Lycoming SB 342G, Supplement No. 2,
dated January 23, 2014 be added to this AD. Lycoming said that SB 342G,
Supplement No. 2 removes the eight inch spacing dimension between
clamps and corrects Diagram No. 30 for the IO-540-M1C5 engine model.
We agree. We changed this AD to include Lycoming SB 342G,
Supplement No. 2.
Request To Allow Previously Approved Alternative Methods of Compliance
(AMOCs)
Central Airlines requested that AMOCs previously approved in AD
2008-14-07 and AD 2011-26-04 be allowed for use in this AD.
We agree. We changed the AMOC paragraph in this AD by adding:
``AMOCs previously approved for AD 2008-14-07, Amendment 39-15602 (73
FR 39574, July 10, 2008) (``AD 2008-14-07'') and AD 2011-26-04,
Amendment 39-16894 (76 FR 79051, December 21, 2011) (``AD 2011-26-04'')
are approved as AMOCs to the corresponding requirements in paragraph
(e) of this AD.''
Request To Change Applicability
An anonymous commenter requested that Continental and Jacobs R-755
engines, be added to the applicability of this AD. There was no
justification provided for the request to add Continental engine(s).
The commenter said that the Jacobs R-755 engine uses the same fuel
units and Lycoming fuel injector tubes.
We disagree. We have received no data to indicate that any other
engines, including Continental engines, have the same problem as the
Lycoming engines. We also do not agree with adding the Jacbos R-755
engine to the applicability because the unsafe condition for this AD
concerns missing or improperly clamped fuel injector fuel lines. We
have received no reports of problems with fuel injector fuel lines for
the R-755; therefore, the R-755 engine does not need to be included in
this AD. We did not change this AD.
Correction to Applicability
Since we issued the NPRM (78 FR 70240, November 25, 2013) (``the
NPRM''), we determined that a discussion of a change to the engine
model applicability was omitted from the NPRM. Engine model LIO-360-M1A
was removed from the Applicability paragraph in this AD because the
fuel tube inspections are documented in the ALS for this engine model.
We also determined that the NPRM incorrectly stated that the
proposed AD action would add three engine models to the applicability
list of the affected engines. The NPRM added two engine models, the IO-
540-C1C5 and IO-540-D4B5, to applicability list of affected engines.
Correction to the Costs of Compliance
Since we issued the NPRM, we determined that the Costs of
Compliance paragraph was incorrect. We changed the Costs of Compliance
paragraph in this AD to correct that error.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously. We have determined that
these changes:
[Agr]re consistent with the intent that was proposed in
the NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.
Costs of Compliance
We estimate that this AD will affect about 37,270 engines installed
on airplanes of U.S. registry. We also estimate that it will require 1
hour to inspect 19,081 four cylinder engines, 1.5 hours to inspect
18,000 six cylinder engines, and 2 hours to inspect 189 eight cylinder
engines. The average labor rate is $85 per hour. Based on these
figures, we estimate the cost of this AD on U.S. operators to be
$3,949,015.
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
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.
