Airworthiness Directives; Lycoming Engines, Fuel Injected
Reciprocating Engines
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) for certain fuel injected reciprocating engines manufactured by
Lycoming Engines. That AD currently requires inspection, and
replacement if necessary, of externally mounted fuel injector fuel
lines. This AD requires the same actions but adds additional engine
models and clarifies certain compliance time wording. This 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 AD results from Lycoming Engines revising their Mandatory Service
Bulletin to add new engine models requiring inspection, and from the
need to clarify a repetitive inspection compliance time. We are issuing
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: This AD becomes effective August 14, 2008. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of August 14, 2008.
ADDRESSES: You can get the service information identified in this AD
from Lycoming Engines, 652 Oliver Street, Williamsport, PA 17701, or go

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 by
superseding AD 2002-26-01, Amendment 39-12986 (67 FR 78965, December
27, 2002), with a proposed AD. The proposed AD applies to certain fuel
injected reciprocating engines manufactured by Lycoming Engines. We
published the proposed AD in the Federal Register on January 2, 2008
(73 FR 87). That action proposed to:
Require the same actions as AD 2002-26-01; and
Add additional engine models, clarify certain compliance
time wording; and
Exempt 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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains this AD, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is provided in
the ADDRESSES section. Comments will be available in the AD docket
shortly after receipt.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
One commenter, a private citizen, states that in the proposed AD,
we wish to exempt engines that have a maintenance manual that deals
with this subject. He asks how the mechanic is to know if an engine has
a maintenance manual, if the mechanic does not have access to that
manual, unless we list the specific engines that are not applicable to
the proposed AD. He states that we should either make the AD applicable
to fuel injected Lycoming Engines and then list the applicable and
nonapplicable engines, or do not change the AD.
We do not agree. If the engine has an ``I'' in the prefix of the
engine model and the engine has external fuel lines, the fuel lines
require inspection. For engines that have a Maintenance Manual, the
required inspection will be described in the Airworthiness
[[Page 39575]]
Limitations Section (ALS) in the engine's Maintenance Manual. For
engines that do not have a Maintenance Manual, the required inspection
will be described in this AD and Lycoming Mandatory Service Bulletin
No. 342E. The mechanic is required to have the Instructions for
Continued Airworthiness when performing maintenance (refer to 14 CFR
43.13). Having the manual or access to the manual, of an airplane or
engine undergoing maintenance is just as important as having the proper
tools to perform the maintenance on an aircraft or engine. We added
language in paragraph (e) to clarify that engine models with an ALS are
not included in Table 1 and therefore are exempted from compliance with
this AD.
One commenter, a private citizen, states that the proposed AD
should be expanded to include any other certified engines utilizing the
same fuel injection setup and parts as the Lycoming engines. One
example is the Jacobs R-755 engine that can be converted to a fuel
injection system via Supplemental Type Certificate held by Radial
Engines, LTD. This installation uses a modified IO-720 fuel injection
system, including the same fuel injection lines that are the subject of
the AD.
We do not agree. The unsafe condition for this AD is the lack of
proper maintenance of the fuel injector lines and support clamps. The
unsafe condition is not a problem with the design or manufacture of
fuel injector 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. The support clamps
dampen fuel line vibration due to the impact of cooling air and
vibration from the aircraft/engine. When the lines and clamps are
accessible and support clamp installation is easier, as in the case of
the Jacobs R-755 engine, the clamps are properly installed and there
has not been a reported problem. Since there has not been a reported
problem with the fuel injector lines on the R-755 engine, or any other
engine, there is no reason to include any other engine in the AD. We
did not change the AD.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD as proposed.
Costs of Compliance
We estimate that 17,740 engines installed on aircraft of U.S.
registry will be affected by this AD. We also estimate that it will
take about 1 work-hour to inspect and replace all lines on a four-
cylinder engine, 1.5 work-hours to inspect and replace all lines on a
six-cylinder engine, and 2 work-hours to inspect and replace all lines
on an eight-cylinder engine. We also estimate that the average labor
rate is $80 per work-hour. Required parts will cost about $484 for a
four-cylinder engine, $726 for a six-cylinder engine, and $968 for an
eight-cylinder engine. Based on these figures, the total cost per
airplane of the AD to U.S. operators is estimated as follows:
$564 for a four-cylinder engine.
$846 for a six-cylinder engine.
$1,128 for an eight-cylinder engine.
We estimate the total cost to U.S. operators to be $11,062,860.
Special Flight Permits Paragraph Removed
Paragraph (e) of the superseded AD, AD 2002-26-01, contains a
paragraph pertaining to special flight permits. Even though this final
rule does not contain a similar paragraph, we have made no changes with
regard to the use of special flight permits to operate the airplane to
a repair facility to do the work required by this AD. In July 2002, we
published a new Part 39 that contains a general authority regarding
special flight permits and airworthiness directives. See Docket No.
FAA-2004-8460, Amendment 39-9474 (69 FR 47998, July 22, 2002). Thus,
when we now supersede ADs we will not include a specific paragraph on
special flight permits unless we want to limit the use of that general
authority granted in section 39.23.
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 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); and
(3) 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.
We prepared a summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary at the
address listed under ADDRESSES.
