ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) for Lycoming Engines IO, (L)IO, TIO, (L)TIO, AEIO, AIO, IGO, IVO,
and HIO series reciprocating engines, TCM TSIO-360-RB reciprocating
engines, and Superior Air Parts, Inc. IO-360 series reciprocating
engines with certain Precision Airmotive LLC RSA-5 and RSA-10 series
fuel injection servos. That AD currently requires inspecting servo
plugs for looseness and damage on fuel injection servos that have a
servo plug gasket, part number (P/N) 365533, installed, and if loose,
inspecting the servo regulator cover threads for damage, inspecting the
gasket for damage, reinstalling acceptable parts, and torquing the
servo plug to a new, higher torque to maintain the proper clamp-up
force between the plug and cover. This AD requires the same
inspections, except if the plug is found loose, servo plug gasket, P/N
365533, must be replaced with a new, improved gasket, P/N 2577258. This
AD also requires replacement by December 31, 2009, of servo plug
gaskets, P/N 365533, manufactured and made available on or after August
22, 2006, as mandatory terminating action to the repetitive inspections
required by this AD. This AD also prohibits the installation of any
servo plug gasket, P/N 365533. This AD also clarifies the TCM engine
model applicability, and adds Bendix RSA-5 and RSA-10 series fuel
injection servos to the applicability. This AD results from Precision
Airmotive LLC
[[Page 4124]]
introducing the installation of a new improved servo plug gasket, P/N
2577258, to the affected Precision Airmotive LLC RSA-5 and RSA-10
series, and Bendix RSA-5 and RSA-10 series, fuel injection servos. We
are issuing this AD to prevent a lean running engine, which could
result in a substantial loss of engine power and subsequent loss of
control of the airplane.

SUPPLEMENTARY INFORMATION: The FAA amends 14 CFR part 39 by superseding
AD 2008-08-14, Amendment 39-15466 (73 FR 19977, April 14, 2008). That
AD requires:
Inspecting servo plugs for looseness and damage on fuel
injection servos that have a servo plug gasket, P/N 365533 installed
since August 22, 2006, and if loose;
Inspecting both the threads on the servo plug and the
servo regulator cover for damage;
Inspecting the gasket for damage, reinstalling acceptable
parts; and
Torquing the servo plug to a new, higher torque to
maintain the proper clamp-up force between the plug and cover.
That AD was the result of eighteen reports of fuel injection servo
plugs, P/N 383493 that had loosened or completely backed out of the
threaded plug hole on the regulator cover of the fuel injection servo.
That condition, if not corrected, could result in a lean running
engine, which could result in a substantial loss of engine power and
subsequent loss of control of the airplane.
Actions Since AD 2008-08-14 Was Issued
Since that AD was issued, Precision Airmotive LLC introduced the
installation of a new improved servo plug gasket, P/N 2577258, to the
Precision Airmotive LLC, RSA-5 and RSA-10 series, and Bendix, RSA-5 and
RSA-10 series, fuel injection servos. Installation of this gasket with
a new higher torque eliminates repetitive inspections of the servo
plug.
Also since that AD was issued, we discovered that we inadvertently
omitted certain Bendix, RSA-5 and RSA-10 series, fuel injection servos,
from the AD applicability. We now include those fuel injection servos
in this AD applicability.
FAA's Determination and Requirements of This AD
The unsafe condition described previously is likely to exist or
develop on other engines of the same type design. We are issuing this
AD to prevent a lean running engine, which could result in a
substantial loss of engine power and subsequent loss of control of the
airplane. This AD requires:
Inspecting servo plugs for looseness and damage on
affected fuel injection servos that have a servo plug gasket, P/N
365533, installed, and if loose;
Inspecting both the servo plug and regulator threads for
damage;
Replacing gasket P/N 365533, with gasket P/N 2577258;
Torquing the servo plug to a new, higher torque to
maintain the proper clamp-up force between the plug and cover; and
By December 31, 2009, as mandatory terminating action to
the repetitive inspections required by this AD, replacing all servo
plug gaskets, P/N 365533 on affected servos, with new, improved gasket,
P/N 2577258, and prohibiting the installation of P/N 365533 gaskets.
FAA's Determination of the Effective Date
Since an unsafe condition exists that requires the immediate
adoption of this AD, we have found that notice and opportunity for
public comment before issuing this AD are impracticable, and that good
cause exists for making this amendment effective in less than 30 days.

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 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.
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.

the affected Precision Airmotive LLC RSA-5 and RSA-10 series, and
Bendix, RSA-5 and RSA-10 series, fuel injection servos. We are
issuing this AD to prevent a lean running engine, which could result
in a substantial loss of engine power and subsequent loss of control
of the airplane.
Compliance
(f) You are responsible for having the actions required by this
AD performed before further flight, unless the actions have already
been done.
Initial Inspection
(g) Before further flight, inspect the fuel injection servo
plug, P/N 383493, for looseness, by attempting to turn it by hand,
while being careful not to damage the safety wire or seal. If the
plug moves, it is loose.
(h) If the plug is not loose, go to paragraph (j) of this AD.
(i) If the plug is loose, do the following:
(1) Carefully cut and remove the safety wire that spans between
the servo plug and regulator cover only.
(2) Remove the servo plug and gasket, P/N 365533, that is behind
the plug. The gasket may be slightly stuck to the regulator cover.
(3) Examine the threads on the servo plug and regulator cover
for damage. Threads should be smooth and consistent, with no burrs
or chips. The servo plug outer diameter threads should also measure
within 0.7419-0.7500-inch.
(4) If the threads on either the servo plug or the regulator
cover are damaged, or do not measure within the limits in paragraph
(i)(3) of this AD, the servo is not eligible for any installation
and must be replaced before further flight.
(5) Replace the gasket, P/N 365533, with a new improved gasket,
P/N 2577258.
(6) While the hex plug is removed, stamp or scribe the letter
``G'' onto the face of the hex plug. Information on stamping or
scribing can be found in Precision Airmotive LLC Mandatory Service
Bulletin (MSB) No. PRS-107 Revision 4, dated July 16, 2008.
(7) When reassembling, do not install any servo plug or
regulator cover that is not eligible for installation. Install a new
gasket, P/N 2577258, onto the servo plug and reassemble the servo
plug to the regulator cover.
(8) Torque the servo plug to a new, higher torque of 90-100 in-
lbs, to maintain the proper clamp-up force between the plug and
cover.
(9) Safety wire the servo plug with 0.015 thru 0.025 inch
diameter wire to the regulator cover screws. Information on properly
safety wiring the plug can be found in Precision Airmotive LLC MSB
No. PRS-107, Revision 4, dated July 16, 2008.
(10) Inspect all other safety wire on the servo. Replace any
that are damaged.
Repetitive Inspections
(j) For servo plugs that passed inspection with a gasket, P/N
365533 installed, at every engine oil change or within every 50
hours of engine run time, whichever occurs first, repeat the
inspection and remedial steps specified in paragraphs (g) through
(i)(10) of this AD.
Mandatory Terminating Action
(k) By December 31, 2009, as mandatory terminating action to the
repetitive inspections required by this AD, replace all servo plug
gaskets, P/N 365533 that are installed on servos affected by this
AD, with gasket, P/N 2577258.
(l) Use paragraphs (i)(1) through (i)(10) of this AD, to do the
gasket replacements.
