(8) Model MD–90–30 airplanes.
(d) Subject
Joint Aircraft System Component (JASC)/
Air Transport Association (ATA) of America
Code 28: Fuel.
(e) Unsafe Condition
This AD was prompted by fuel system
reviews conducted by the manufacturer. We
are issuing this AD to reduce the potential of
ignition sources inside fuel tanks, which, in
VerDate Mar<15>2010

Jkt 226001
combination with flammable fuel vapors,
could result in fuel tank explosions and
consequent loss of the airplane.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
(g) Criteria for Operation
As of 60 months after the effective date of
this AD, no person may operate any airplane
affected by this AD unless an amended type
certificate or supplemental type certificate
that incorporates the design features and
requirements described in paragraphs (g)(1),
(g)(2), and (g)(3) of this AD has been
approved by the Manager, Los Angeles
Aircraft Certification Office (ACO), FAA, and
those design features are installed on the
airplane.
(1) Each electrically powered fuel pump
installed in the center wing tank or auxiliary
fuel tank must have a protective device
installed to detect electrical faults that can
cause arcing and burn through the fuel pump
housing. The same device must shut off the
pump by automatically removing electrical
power from the pump when such faults are
detected. When a fuel pump is shut off as the
result of detection of an electrical fault, the
device must stay latched off until the fault is
cleared through maintenance action and
verified that the pump and the electrical
power feed is safe for operation.
(2) Additional design features must be
installed to detect when any center wing tank
or auxiliary fuel tank pump is running in an
empty fuel tank. The prospective pump
shutoff system must shut off each pump no
later than 60 seconds after the fuel tank is
emptied. The pump shutoff system design
must preclude undetected running of a fuel
pump in an empty tank, after the pump was
commanded off manually or automatically.
(3) The implementation of the design
features defined in paragraphs (g)(1) and
(g)(2) of this AD must ensure that a fuel
pump cannot be shut off due to system
failures including nuisance shutoffs sooner
than 100,000 hours’ mean time between
failures (MTBF).
Note 1: After accomplishing the
installation specified in paragraph (g) of this
AD, maintenance and/or preventative
maintenance under 14 CFR part 43 is
permitted provided the maintenance does not
result in changing the AD-mandated
configuration (reference 14 CFR 39.7).
(h) Alternative Methods of Compliance
(AMOCs)
(1) The Manager, Los Angeles ACO, FAA,
has the authority to approve AMOCs for this
AD, if requested using the procedures found
in 14 CFR 39.19. In accordance with 14 CFR
39.19, send your request to your principal
inspector or local Flight Standards District
Office, as appropriate. If sending information
directly to the manager of the ACO, send it
to the attention of the person identified in the
Related Information section of this AD.
(2) Before using any approved AMOC,
notify your appropriate principal inspector,
or lacking a principal inspector, the manager
of the local flight standards district office/
certificate holding district office.

Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to supersede an
existing airworthiness directive (AD)
that applies to certain Cessna Aircraft
Company (Cessna) Models 172R and
172S airplanes. The existing AD
requires you to inspect the fuel return
line assembly for chafing; replace the
fuel return line assembly if chafing is
found; and inspect the clearance
between the fuel return line assembly
and both the right steering tube
assembly and the airplane structure,
adjusting as necessary. Since we issued
that AD, we have received a field report
of a fuel return line chafing incident on
a Cessna Model 172 airplane with a
serial number (S/N) that was not
included in the AD. This proposed AD
would retain the actions of the current
AD and add S/Ns to the Applicability
section of the AD. Chafing of the fuel
return line assembly could lead to fire.
We are proposing this AD to correct the
unsafe condition on these products.
DATES: We must receive comments on
this proposed AD by December 29,
2011.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following
methods:

Discussion
On January 22, 2008, we issued AD
2008–03–02, Amendment 39–15351 (73
FR 5737, January 31, 2008), for certain
Cessna Models 172R and 172S
airplanes. That AD requires you to
inspect the fuel return line assembly for
chafing; replace the fuel return line
assembly if chafing is found; and
inspect the clearance between the fuel
return line assembly and both the right
steering tube assembly and the airplane
structure, adjusting as necessary. That
AD resulted from reports of chafed fuel
return line assemblies, which were
caused by the fuel return line assembly
rubbing against the right steering tube
assembly during full rudder pedal
actuation. We issued that AD to detect
and correct chafing of the fuel return
line assembly, which could result in
fuel leaking under the floor and fuel
vapors entering the cabin. This
condition could lead to fire under the
floor or in the cabin area.
Actions Since Existing AD Was Issued
Since we issued AD 2008–03–02 (73
FR 5737, January 31, 2008), we received
a field report of a fuel return line
chafing incident on a Cessna Model 172
airplane with an S/N that was not
included in the AD.
September 22, 2011. The service
information describes the following
procedures:
• Inspecting the fuel return line
assembly;
• Replacing the fuel return line
assembly if chafing is found; and
• Inspecting the clearance between
the fuel return line assembly and both
the right steering tube assembly and the
airplane structure, adjusting as
necessary.
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 the same
type design.
Proposed AD Requirements
This proposed AD would retain all of
the requirements of AD 2008–03–02 (73
FR 5737, January 31, 2008). This
proposed AD would add airplanes to the
applicability statement of the current
AD.
Change to Existing AD
This proposed AD would retain all
requirements of AD 2008–03–02 (73 FR
5737, January 31, 2008). Since AD
2008–03–02 was issued, the AD format
has been revised, and certain paragraphs
have been rearranged. As a result, the
corresponding paragraph identifiers
have changed in this proposed AD, as
listed in the following table:

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.
jlentini on DSK4TPTVN1PROD with PROPOSALS
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.

Examining the AD Docket
Actions Since Existing AD Was Issued
Since we issued AD 2007–12–07 (72
FR 31174, June 6, 2007), we received
two reports of ice crystal condition
flameouts on engines equipped with
ECU software version 8.2.Q1. Prompted
by these reports, GE developed ECU
software version 8.2.R with improved
inclement weather capability, and
enhanced fuel metering valve (FMV)
fault handling logic to reduce the risk of
engine IFSD caused by intermittent
FMV feedback signals.
Subsequently, we received reports of
eight engine IFSD events and four
engine flameout ground events. These
events were caused by ignition system
induced noise creating dual-channel
faults in the CPU. The event engines
were operating with 8.2.Q1 and 8.2.R
versions of ECU software and equipped
with the new generation of front panel
assembly (FPA) and pressure subsystem
(PSS) circuit boards. Prompted by these
reports, GE developed an ECU hardware
fix to eliminate the potential for dualchannel CPU faults due to ignition
system-induced noise. This proposed
AD supersedure removes the affected
ECUs from the fleet. These ECUs, if not
corrected, could result in flameout or

SUPPLEMENTARY INFORMATION:
Comments Invited
Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to supersede an
existing airworthiness directive (AD)
that applies to all GE CF6–80C2B series
turbofan engines. The existing AD
currently requires installing software
version 8.2.Q1 to the engine electronic
control unit (ECU), which increases the
engine’s margin to flameout. Since we
issued that AD, we have received
reports of additional engine events. This
proposed AD would require the removal
of the affected ECUs from service. We
are proposing this AD to prevent engine
flameout or un-commanded engine inflight shutdown (IFSD) of one or more
engines, leading to an emergency or
forced landing of the airplane.
DATES: We must receive comments on
this proposed AD by January 13, 2012.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following
methods:

Discussion
On May 30, 2007, we issued AD
2007–12–07, Amendment 39–15085 (72
FR 31174, June 6, 2007), for all GE CF6–
80C2B series turbofan engines. That AD
requires installing software version
8.2.Q1 to the ECU, which increases the
engine’s margin to flameout. That AD
was prompted by multiple reports of
flameout events during flight on engines
with an ECU software version preceding
version 8.2.Q1, including reports of
events where all engines simultaneously
experienced a flameout. Investigation
showed that exposure to ice crystals
during flight was associated with these
flameout events. That AD action was
intended to minimize the potential of an
engine flameout event caused by ice
accretion and shedding during flight.

Airworthiness Directives; Cessna Aircraft Company Airplanes
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 Cessna Aircraft Company (Cessna) Models
172R and 172S airplanes. The existing AD requires you to inspect the
fuel return line assembly for chafing; replace the fuel return line
assembly if chafing is found; and inspect the clearance between the
fuel return line assembly and both the right steering tube assembly and
the airplane structure, adjusting as necessary. Since we issued that
AD, we have received a field report of a fuel return line chafing
incident on a Cessna Model 172 airplane with a serial number (S/N) that
was not included in the AD. This proposed AD would retain the actions
of the current AD and add S/Ns to the Applicability section of the AD.
Chafing of the fuel return line assembly could lead to fire. We are
proposing this AD to correct the unsafe condition on these products.
DATES: We must receive comments on this proposed AD by December 29,
2011.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:
Comments Invited
We invite you to send any written relevant data, views, or
arguments about this proposed AD. Send your comments to an address
listed under the ADDRESSES section. Include ``Docket No. FAA-2011-1245;
Directorate Identifier 2011-CE-033-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this proposed AD. We
will consider all comments received by the closing date and may amend
this proposed AD because of those comments.
We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this proposed AD.
Discussion
On January 22, 2008, we issued AD 2008-03-02, Amendment 39-15351
(73 FR 5737, January 31, 2008), for certain Cessna Models 172R and 172S
airplanes. That AD requires you to inspect the fuel return line
assembly for chafing; replace the fuel return line assembly if chafing
is found; and inspect the clearance between the fuel return line
assembly and both the right steering tube assembly and the airplane
structure, adjusting as necessary. That AD resulted from reports of
chafed fuel return line assemblies, which were caused by the fuel
return line assembly rubbing against the right steering tube assembly
during full rudder pedal actuation. We issued that AD to detect and
correct chafing of the fuel return line assembly, which could result in
fuel leaking under the floor and fuel vapors entering the cabin. This
condition could lead to fire under the floor or in the cabin area.
Actions Since Existing AD Was Issued
Since we issued AD 2008-03-02 (73 FR 5737, January 31, 2008), we
received a field report of a fuel return line chafing incident on a
Cessna Model 172 airplane with an S/N that was not included in the AD.
Relevant Service Information
We reviewed Cessna Mandatory Service Bulletin SB07-28-01, dated
June 18, 2007, and Cessna Service Bulletin SB07-28-01, Revision 1,
dated September 22, 2011. The service information describes the
following procedures:
Inspecting the fuel return line assembly;
Replacing the fuel return line assembly if chafing is
found; and
Inspecting the clearance between the fuel return line
assembly and both the right steering tube assembly and the airplane
structure, adjusting as necessary.
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 the same type design.
Proposed AD Requirements
This proposed AD would retain all of the requirements of AD 2008-
03-02 (73 FR 5737, January 31, 2008). This proposed AD would add
airplanes to the applicability statement of the current AD.
Change to Existing AD
This proposed AD would retain all requirements of AD 2008-03-02 (73
FR 5737, January 31, 2008). Since AD 2008-03-02 was issued, the AD
format has been revised, and certain paragraphs have been rearranged.
As a result, the corresponding paragraph identifiers have changed in
this proposed AD, as listed in the following table:
Revised Paragraph Identifiers
------------------------------------------------------------------------
Corresponding requirement in
Requirement in AD 2008-03-02 this proposed AD
------------------------------------------------------------------------
paragraph (e)(1).......................... paragraph (g)(1) and (g)(2)
paragraph (e)(2).......................... paragraph (h)
paragraph (e)(3).......................... paragraph (i)
------------------------------------------------------------------------
Costs of Compliance
We estimate that this proposed AD affects 768 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on
Action Labor cost Parts cost Cost per U.S.
product operators
----------------------------------------------------------------------------------------------------------------
Inspection of the fuel return line 1 work-hour x $85 per Not applicable......... $85 $65,280
assembly for chafing and clearance. hour = $85.
----------------------------------------------------------------------------------------------------------------
The difference in estimated costs of this proposed AD and AD 2008-
03-02 (73 FR 5737, January 31, 2008) is an increase in the estimated
labor cost for those airplanes affected by AD 2008-
[[Page 70381]]
03-02 and the costs of the additional airplanes added to the proposed
AD.
We estimate the following costs to do any necessary replacements
that would be required based on the results of the proposed inspection.
We have no way of determining the number of aircraft that might need
these replacements:
On-Condition Costs
------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
------------------------------------------------------------------------
Replacement of the fuel 0.5 work-hour x $123 $165.50

between the fuel return line
assembly and both the right
steering tube assembly and
the airplane structure.
------------------------------------------------------------------------
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, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
