[Docket No. 92-ANE-56-AD; Amendment 39-12986; AD 2002-26-01]
RIN 2120-AA64
Airworthiness Directives; Textron Lycoming Division, AVCO
Corporation Fuel Injected Reciprocating Engines.
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes two existing airworthiness
directives (AD's), that are applicable to certain Textron Lycoming fuel
injected reciprocating engines. These AD's currently require
inspection, and replacement if necessary, of externally mounted fuel
injector fuel lines. These amendments require adding engine series to
the applicability that have been identified with the potential for the
same problem and necessitate being included in the list of Textron
Lycoming fuel injected reciprocating engine series. This amendment is
prompted by the need to ensure that the additional Textron Lycoming
fuel injected engine series listed in this final rule receive the same
inspections as series covered by the current AD's. The actions
specified by this AD are intended to prevent failure of the fuel
injector fuel lines allowing fuel to spray into the engine compartment,
resulting in an engine fire.
DATES: Effective January 31, 2003. The incorporation by reference of
certain publications listed in the regulations is approved by the
Director of the Federal Register as of January 31, 2003.
ADDRESSES: The service information referenced in this AD may be
obtained from Textron Lycoming, 652 Oliver Street, Williamsport, PA
17701, telephone (570) 323-6181; fax (570) 327-7101. This information
may be examined, by appointment, at the Federal Aviation Administration
(FAA), New England Region, Office of the Regional Counsel, 12 New
England Executive Park, Burlington, MA; or at the Office of the Federal
Register, 800 North Capitol Street, NW, suite 700, Washington, DC.
FOR FURTHER INFORMATION CONTACT: Norm Perenson, Aerospace Engineer, New
York Aircraft Certification Office, FAA, Engine and Propeller
Directorate, 10 Fifth Street, 3rd floor, Valley Stream, NY 11581-1200;
telephone (516) 256-7537; fax (516) 568-2716.
SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) by superseding AD 93-02-05,
Amendment 39-8487 (58 FR 26056, April 30, 1993), which is applicable to
certain Textron Lycoming fuel injected reciprocating engines that
currently require inspection, and replacement if necessary, of
externally mounted fuel injector fuel lines, was published in the
Federal Register on March 11, 2002 (67 FR 10859). Because of the
requests of two commenters, this AD has been expanded and will also
supersede AD 93-05-22, Amendment 39-8525, (58 FR 19768, April 16,
1993), which is only applicable to Lycoming TIO-540-S1AD. This dual
supersedure will eliminate duplication and provide proper inspection
and replacement instructions for the TIO-540-S1AD engines. The NPRM
supersedure proposed to require that additional engine series that have
been identified with the potential for the same problem, be included in
the list of Textron Lycoming fuel injected reciprocating engine series
listed in the AD applicability, in accordance with Textron Lycoming
Mandatory Service Bulletin (MSB) No. 342D, dated July 10, 2001.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comments received.
AD Not Necessary and Duplicates another AD
Two commenters point out that the current AD does not apply to the
TIO-540-S1AD engines and the same unsafe condition in those engines is
covered by a separate action, AD 93-05-22, Amendment 39-8525. The
commenters request that either this action also supersede AD 93-05-22
or that this action not apply to the TIO-540-S1AD engines.
The FAA agrees. AD 93-05-22, Amendment 39-8525, is also superseded
by this AD, and the TIO-540-S1AD engines have been included in the
Applicability.
Clamps Installed On Factory Shipped Engines
One commenter states that engines shipped from the factory have all
of the fuel line clamps installed, and no action is required until a
maintenance action is performed in the field that disturbs the
clamping. The commenter states that exempting engines shipped from the
factory would avoid an unnecessary inspection after an engine has been
delivered after purchase or overhaul.
The FAA disagrees. The current AD and this superseding AD already
account for new and newly overhauled engines by allowing those engines
50 hours after the effective date before an initial inspection is
required, as opposed to 10 hours for engines that have been maintained
since new or since overhaul. The FAA has determined that inspections
are necessary even before maintenance is performed to ensure that the
fuel injector lines remain properly clamped. Therefore, the FAA made no
changes to the rule with respect to this request. Engines shipped from
the factory (new or overhauled) will have passed one or more
inspections that will satisfy the requirements of this AD.
Engines That Have Been Previously Inspected
One commenter states that Textron Lycoming Mandatory Service
Bulletin (MSB) No. 342D should also be included in the proposal's
paragraph (a) listing after MSB No. 342C under the section titled
``Engines That Have Been Previously Inspected''. The commenter states
there will be engines that have already been inspected to Textron
Lycoming MSB No. 342D. This would allow an operator to take credit for
a previously completed inspection.
The FAA agrees. Reference to Textron Lycoming MSB No. 342D has been
added to paragraph (a) in the final rule.
[[Page 78966]]
Engines That Have Not Been Inspected
One commenter states that Textron Lycoming MSB No. 342D should also
be included in the proposal's paragraph (b) listing after MSB No. 342C
under the section titled ``Engines That Have Not Been Inspected''. The
commenter states that there will be engines that have not been
inspected to Textron Lycoming MSB No. 342D. This addition would allow a
reference to the latest Service Bulletin.
The FAA agrees. Reference to Textron Lycoming MSB No. 342D has been
added to paragraph (b) of the final rule.
Distances for Clamping Locations
One commenter states that since vibration seems to be a concern,
there should be a distance provided from the engine case to the clamp
on the push rod tube that would give maximum line vibration reduction
to reduce the effects of engine vibration.
The FAA disagrees. While the FAA understands that vibration is a
concern, the FAA does not agree that a change is required to the AD.
The information to dampen the vibrations is contained in Textron
Lycoming MSB No. 342D. No change has been made to this final rule.
Additional Items Installed on the Clamp
One commenter requests guidance relative to whether other items can
be installed on the clamp around the push rod tube, and if not, a
statement added that the clamp around the push rod tube must ``stand
alone'' and only be used for the fuel line.
The FAA does not agree. Proper clamping procedures are contained in
MSB No. 342D. No change has been made to the rule.
Service Bulletin Issue Dates Added
Service Bulletin (SB) issue dates were omitted in NPRM Docket No.
92-ANE-56-AD in the paragraphs entitled ``Engines That Have Been
Previously Inspected'' and ``Engines That Have Not Been Inspected''.
The SB issue dates are added to this AD in the paragraphs referenced
above.
Difference Between Service Bulletin and AD Compliance Time
Textron Lycoming MSB No. 342D Time of Compliance statement states,
``Check every 100 hours,'' * * * This AD states, ``* * * at each 100-
hour inspection * * *''. The 100-hour inspections may be extended to
110 hours provided the next inspection is performed at 90 hours. The
requirements of this AD has precedence over Textron Lycoming MSB No.
342D.
After careful review of the available data, including the comments
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule with the changes described
previously. The FAA has determined that these changes will neither
increase the economic burden on any operator nor increase the scope of
the AD.
Economic Analysis
There are approximately 4,160 Textron Lycoming engines of the
affected design in the worldwide fleet. The FAA estimates that 2,496
engines installed on aircraft of U.S. registry will be affected by this
AD, that it will take approximately 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 hours to inspect and
replace all lines on an eight-cylinder engine, and that the average
labor rate is $60 per work hour. Required parts will cost approximately
$440.00 for a four-cylinder engine, $660.00 for a six-cylinder engine,
and $880.00 for an eight-cylinder engine. Based on these figures, the
total cost per airplane of this AD on U.S. operators is estimated as
follows:
[sbull] $500.00 for a four-cylinder engine.
[sbull] $750.00 for a six-cylinder engine.
[sbull] $1000.00 for an eight-cylinder engine.
Regulatory Analysis
This final rule does not have federalism implications, as defined
in Executive Order 13132, because it 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. Accordingly,
the FAA has not consulted with state authorities prior to publication
of this final rule.
For the reasons discussed above, I certify that this action (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); 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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
by contacting the Rules Docket at the location provided under the
caption ADDRESSES.

dated July 10, 2001 as follows:
(1) For engines that have not yet had any fuel line maintenance
done, or have not had any fuel line maintenance done since new or
since the last overhaul, inspect within 50 hours time-in-service
after the effective date of this AD, and replace as necessary, the
fuel injector fuel lines and clamps between the fuel manifold and
the fuel injector nozzles that do not meet all conditions specified
in Textron Lycoming MSB No. 342D, dated July 10, 2001.
(2) For all other engines, inspect within 10 hours time-in-
service after the effective date of this AD, and replace as
necessary, the fuel injector fuel lines and clamps between the fuel
manifold and the fuel injector nozzles that do not meet all
conditions specified in Textron Lycoming MSB No. 342D, dated July
10, 2001.
Repetitive Inspections
(c) Thereafter, at each annual inspection, at each 100-hour
inspection, at each engine overhaul, and after any maintenance has
been done on the engine where any clamp (or clamps) on a fuel
injector line (or lines) has been disconnected, moved, or loosened,
inspect the fuel injector fuel lines and clamps and replace as
necessary any fuel injector fuel line and clamp that does not meet
all conditions specified in Textron Lycoming MSB No. 342D, dated
July 10, 2001.
Alternative Methods of Compliance
(d) An alternative method of compliance or adjustment of the
compliance time that provides an acceptable level of safety may be
used if approved by the Manager, New York Aircraft Certification
Office (ACO). Operators must submit their request through an
appropriate FAA Principal Maintenance Inspector, who may add
comments and then send it to the Manager, New York ACO.
Note 3: Information concerning the existence of approved
alternative methods of compliance with this airworthiness directive,
if any, may be obtained from the New York ACO.
Special Flight Permits
(e) Special flight permits may be issued in accordance with
Sec. Sec. 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be done.
Documents That Have Been Incorporated By Reference
(f) The clamp inspection and installations must be done in
accordance with Textron Lycoming MSB No. 342D, dated July 10, 2001.
This incorporation by reference was approved by the Director of the
