The loss of internal components from the low fuel pressure switch into the fuel system may lead to a rupture of the HP–LP pumps drive shaft shear pin, and thus to a possible uncommanded in-flight shutdown (IFSD). On a single-engine helicopter, an uncommanded IFSD results in an emergency autorotation landing and in certain conditions may lead to an accident. ‘We are issuing this AD to prevent forced autorotation landing, or an accident.’ ’’ Actions and Compliance (e) Unless already done, do the following actions. (1) No later than September 30, 2009, perform a one-time inspection of the HMU, using paragraph 2 of Turbomeca Mandatory Service Bulletin (MSB) No. 292 73 2826, dated March 13, 2008, to identify the low fuel pressure switch installed on the adjusted HMU. (2) If a Hydra-Electric low fuel pressure switch, part number (P/N) 9 550 17 956 0 is installed: (i) Inspect the low fuel pressure switch and chamber of the HMU body. (ii) If any parts from the low fuel pressure switch are missing or found in the HMU chamber, replace the HMU with a new or overhauled HMU equipped with a serviceable low fuel pressure switch. (iii) If not, replace only the low fuel pressure switch with a serviceable low fuel pressure switch. (3) If a low fuel pressure switch other than a Hydra-Electric low fuel pressure switch, P/ N 9 550 17 956 0 is installed, and that is the only type of low fuel pressure switch that has been installed since new, repair, or overhaul, no further action is required. (4) If a Hydra-Electric switch, P/N 9 550 17 956 0, has been or may have been installed previously, and the conditions of paragraph (e)(3) of this AD are not met: (i) Inspect the chamber of the HMU body. (ii) If any parts are found in the HMU chamber, replace the HMU with a new or overhauled HMU equipped with a serviceable low fuel pressure switch.

IO–360 Series Reciprocating Engines With Certain Precision Airmotive LLC RSA–5 and RSA–10 Series, and Bendix RSA–5 and RSA–10 Series, Fuel Injection Servos AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). 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 E:\FR\FM\23JAR1.SGM 23JAR1 rwilkins on PROD1PC63 with RULES 4124 Federal Register / Vol. 74, No. 14 / Friday, January 23, 2009 / Rules and Regulations 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. DATES: Effective February 9, 2009. We must receive any comments on this AD by March 24, 2009.

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: VerDate Nov<24>2008 16:34 Jan 22, 2009 Jkt 217001 • 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 PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 • 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.

AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Some operators have reported occurrences of loss of the AC BUS 1 with subsequent loss of the AC ESS BUS and DC ESS BUS, resulting in the loss of 5 upper Display Units and the loss of integral lighting. In this situation, flight crew[s] have reported concerns in reading the standby instruments when the DOME lights were selected to OFF. This situation, if not corrected, could increase the workload of the flight crew * * *. * * * * * The unsafe condition is reduced ability of the flightcrew to maintain the safe flight and landing of the airplane in adverse operating conditions. We are issuing this AD to require actions to correct the unsafe condition on those products. DATES: This AD becomes effective February 27, 2009. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of February 27, 2009. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 1200 New Jersey Avenue, SE., Washington, DC.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on May 20, 2008 (73 FR 29089). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Some operators have reported occurrences of loss of the AC BUS 1 with subsequent loss of the AC ESS BUS and DC ESS BUS, resulting in the loss of 5 upper Display Units and the loss of integral lighting. In this situation, flight crews[s] have reported concerns in reading the standby instruments when the DOME lights were selected to OFF. This situation, if not corrected, could increase the workload of the flight crew * * *. This Airworthiness Directive (AD) mandates the modification of the electrical supply logic by adding a back-up supply on the battery hot bus for the under glare shield flood lighting. The unsafe condition is reduced ability of the flightcrew to maintain the safe flight and landing of the airplane in adverse operating conditions. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received.

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

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.

DATES: Effective February 9, 2009.

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.

Comments Invited

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.

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.
