14 CFR Part 39
[Docket No. FAA-2007-0218; Directorate Identifier 92-ANE-56-AD]
RIN 2120-AA64
Airworthiness Directives; Lycoming Engines, Fuel Injected
Reciprocating Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede an existing airworthiness directive
(AD) that applies to certain fuel injected reciprocating engines
manufactured by Lycoming Engines. The existing AD currently requires
inspection, replacement if necessary, and proper clamping of externally
mounted fuel injector fuel lines. That AD also exempts engines that
have a Maintenance and Overhaul Manual with an Airworthiness
Limitations Section that requires inspection and replacement, if
necessary, of externally mounted fuel injector lines. This proposed AD
would require the same actions. Since we issued that AD, Lycoming
Engines revised their Mandatory Service Bulletin (MSB) to add engine
models requiring inspections. We are proposing this AD to prevent
failure of the fuel injector fuel lines that would allow fuel to spray
into the engine compartment, resulting in an engine fire.
DATES: We must receive comments on this proposed AD by April 1, 2011.
ADDRESSES: You may send comments by any of the following methods:
Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

Discussion
On June 24, 2008, we issued AD 2008-14-07, Amendment 39-15602 (73
FR 39574), for certain fuel injected reciprocating engines manufactured
by Lycoming Engines. That AD requires inspection, replacement if
necessary, and proper clamping of externally mounted fuel injector fuel
lines. Some of the clamps are difficult to install on the fuel injector
lines and then to the engine, resulting in support clamps being omitted
during field overhaul or repair. Lines not clamped correctly are
subject to engine vibration and wear. That AD resulted from Lycoming
Engines revising their MSB to add engine models requiring inspection,
and from the need to clarify a repetitive inspection compliance time.
We issued that AD to prevent failure of the fuel injector fuel lines
that would allow fuel to spray into the engine compartment, resulting
in an engine fire.
Actions Since Existing AD Was Issued
Since we issued AD 2008-14-07, Lycoming Engines revised their MSB
to add engine models requiring inspection, replacement if necessary,
and proper clamping of externally mounted fuel injector fuel lines.
They also listed some of the physical damages that would reject a tube.
Based on that MSB revision, we would require the inspection in this
proposed AD supersedure to meet all conditions specified in MSB No.
342F, dated June 4, 2010. In addition, we learned that two engines
listed in AD 2008-14-07 do not exist. They are the IO-360-C2G6 and the
TIO-540AE1A5, so we removed them from this proposed AD.
Relevant Service Information
We reviewed Lycoming Engines MSB No. 342F, dated June 4, 2010. The
MSB describes procedures for inspecting, and if necessary replacing the
fuel injector fuel lines. That MSB supersedes Textron Lycoming MSB No.
342E, 342D, MSB No. 342C, MSB No. 342B, Supplement No. 1 to MSB 342B,
MSB 342A, and MSB 342.
[[Page 8662]]
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of these same type
designs.
Proposed AD Requirements
This proposed AD would retain all of the requirements of AD 2008-
14-07. This proposed AD would add the LIO-360-M1A engine, as
applicable.
Costs of Compliance
We estimate that this proposed AD affects 21,180 four-cylinder
engines, 21,449 six-cylinder engines, and 256 eight-cylinder engines
installed on aircraft of U.S. registry. We also estimate that it would
take about 0.2 work-hour to inspect all lines on a four-cylinder
engine, 0.5 work-hour to inspect all lines on a six-cylinder engine,
and 0.7 work-hour to inspect all lines on an eight-cylinder engine. We
also estimate that the average labor rate is $85 per work-hour. We do
not anticipate any additional costs on U.S. operators, as the
inspection would be done in conjunction with other work performed
concurrently. We anticipate no parts to be required. Based on these
figures, the total cost of the proposed AD to U.S. operators for one
inspection of the fleet is $1,372,645.
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 have 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 that the 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, 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
