AGENCY:
SUMMARY: The FAA proposes to
supersede an existing airworthiness
directive (AD) for General Electric
Company (GE) CF34–10E series turbofan
engines. That AD currently requires
removing the fuel inlet strainer from
main fuel pump (MFP) part number
(P/N) 2043M12P03, installing a certain
replacement flange as an interim repair,
remarking the MFP to P/N 2043M12P04,
and performing initial and repetitive
visual inspections of the main fuel filter.
This proposed AD would require
removing MFPs, P/N 2043M12P03 and
2043M12P04 from service and installing
an improved MFP with a different P/N.

This proposed AD results from GE
determining that the cause of MFP fuel
strainer failure is a design problem with
the strainer. We are proposing this AD
to prevent engine in-flight shutdown
due to MFP malfunctions.

Discussion
On September 21, 2006, we issued AD
2006–20–06, Amendment 39–14775 (71
FR 60663, October 16, 2006). That AD
requires removing the MFP inlet strainer
from the MFPs, installing a certain
replacement flange as an interim repair,
remarking the MFP to P/N 2043M12P04,
and performing initial and repetitive
visual inspections of the main fuel filter.
That AD was the result of three reports
of release of the tripod support legs on
the MFP inlet strainer, leading to engine
in-flight shutdown. That condition, if
not corrected, could result in engine inflight shutdown due to MFP
malfunctions.
mstockstill on PROD1PC61 with PROPOSALS
Actions Since AD 2006–20–06 Was
Issued
Since AD 2006–20–06 was issued, GE
determined that the cause of MFP fuel
inlet strainer failure is a design problem
with the strainers installed in the MFPs.
GE has introduced MFP P/N
2043M12P05, which has a more robust
design fuel inlet strainer.
FAA’s Determination and Requirements
of the Proposed AD
We have evaluated all pertinent
information and identified an unsafe
condition that is likely to exist or
develop on other products of this same
type design. For that reason, we are
proposing this AD, which would require
removing MFPs, P/N 2043M12P03 and
2043M12P04 from service and installing
an improved MFP, not later than April
30, 2007.
VerDate Aug<31>2005
13:17 Jan 16, 2007
Jkt 211001
Costs of Compliance
We estimate that this proposed AD
would affect 50 CF34–10E series
turbofan engines installed on airplanes
of U.S. registry. We also estimate that it
would take about 3 work-hours per
engine to perform the proposed actions,
and that the average labor rate is $80 per
work-hour. Required parts would cost
about $4,226 per engine to upgrade the
MFP to a different P/N to make it
serviceable. Based on these figures, we
estimate the total upgrade cost of the
proposed AD to U.S. operators to be
$223,300.
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); and
3. Would 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 regulatory evaluation
of the estimated costs to comply with
this proposed AD. See the ADDRESSES
section for a location to examine the
regulatory evaluation.

I. Background (Regulatory Authorities)
The Federal Food, Drug, and Cosmetic
Act (the act) (21 U.S.C. 301 et. seq.), as
amended by the Medical Device
PO 00000
Frm 00006
Fmt 4702
Sfmt 4702
1951
Amendments of 1976 (the 1976
amendments) (Public Law 94–295), the
Safe Medical Devices Act of 1990 (the
SMDA) (Public Law 101–629), and the
Food and Drug Administration
Modernization Act of 1997 (FDAMA)
(Public Law 105–115), established a
comprehensive system for the regulation
of medical devices intended for human
use. Section 513 of the act (21 U.S.C.
360c) established three categories
(classes) of devices, depending on the
regulatory controls needed to provide
reasonable assurance of their safety and
effectiveness. The three categories of
devices are class I (general controls),
class II (special controls), and class III
(premarket approval).
Under section 513 of the act, devices
that were in commercial distribution
before May 28, 1976 (the date of
enactment of the 1976 amendments),
generally referred to as preamendments
devices, are classified after FDA has: (1)
Received a recommendation from a
device classification panel (an FDA
advisory committee); (2) published the
panel’s recommendation for comment,
along with a proposed regulation
classifying the device; and (3) published
a final regulation classifying the device.
FDA has classified most
preamendments devices under these
procedures.
Devices that were not in commercial
distribution prior to May 28, 1976,
generally referred to as postamendments
devices, are classified automatically by
statute (section 513(f) of the act into
class III without any FDA rulemaking
process. Those devices remain in class
III and require premarket approval,
unless and until the device is
reclassified into class I or II or FDA
issues an order finding the device to be
substantially equivalent, under section
513(i) of the act, to a predicate device
that does not require premarket
approval. The agency determines
whether new devices are substantially
equivalent to predicate devices by
means of premarket notification
procedures in section 510(k) of the act
(21 U.S.C. 360(k)) and part 807 of the
regulations (21 CFR part 807).
Reclassification of classified
postamendments devices is governed by
section 513(f)(3) of the act. This section
provides that FDA may initiate the
reclassification of a device classified
into class III under section 513(f)(1) of
the act, or the manufacturer or importer
of a device may petition the Secretary of
Health and Human Services (the
Secretary) for the issuance of an order
classifying the device in class I or class
II. FDA’s regulations in 21 CFR 860.134

the MFP to P/N 2043M12P04, and performing initial and repetitive visual
inspections of the main fuel filter. This proposed AD would require
removing MFPs, P/N 2043M12P03 and 2043M12P04 from service and
installing an improved MFP with a different P/N. This proposed AD
results from GE determining that the cause of MFP fuel strainer failure
is a design problem with the strainer. We are proposing this AD to

Discussion
On September 21, 2006, we issued AD 2006-20-06, Amendment 39-14775

inlet strainer from the MFPs, installing a certain replacement flange
as an interim repair, remarking the MFP to P/N 2043M12P04, and
performing initial and repetitive visual inspections of the main fuel
filter. That AD was the result of three reports of release of the
tripod support legs on the MFP inlet strainer, leading to engine in-
flight shutdown. That condition, if not corrected, could result in
engine in-flight shutdown due to MFP malfunctions.
Actions Since AD 2006-20-06 Was Issued
Since AD 2006-20-06 was issued, GE determined that the cause of MFP
fuel inlet strainer failure is a design problem with the strainers
installed in the MFPs. GE has introduced MFP P/N 2043M12P05, which has
a more robust design fuel inlet strainer.
FAA's Determination and Requirements of the Proposed AD
We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other products
of this same type design. For that reason, we are proposing this AD,
which would require removing MFPs, P/N 2043M12P03 and 2043M12P04 from
service and installing an improved MFP, not later than April 30, 2007.
Costs of Compliance
We estimate that this proposed AD would affect 50 CF34-10E series
turbofan engines installed on airplanes of U.S. registry. We also
estimate that it would take about 3 work-hours per engine to perform
the proposed actions, and that the average labor rate is $80 per work-
hour. Required parts would cost about $4,226 per engine to upgrade the
MFP to a different P/N to make it serviceable. Based on these figures,
we estimate the total upgrade cost of the proposed AD to U.S. operators
to be $223,300.
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); and
3. Would 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 regulatory evaluation of the estimated costs to
comply with this proposed AD. See the ADDRESSES section for a location
to examine the regulatory evaluation.

The Proposed Amendment
Under the authority delegated to me by the Administrator, the
Federal Aviation Administration proposes to amend 14 CFR part 39 as
follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by removing Amendment 39-14775 (71 FR
60663, October 16, 2006) and by adding a new airworthiness directive to
read as follows:
General Electric Company: Docket No. FAA-2006-25896; Directorate
Identifier 2006-NE-33-AD.
Comments Due Date
(a) The Federal Aviation Administration (FAA) must receive
comments on this airworthiness directive (AD) action by March 19,
2007.
Affected ADs
(b) This AD supersedes AD 2006-20-06, Amendment 39-14755.
Applicability
(c) This AD applies to General Electric Company (GE) CF34-
10E2A1, -10E5, -10E5A1, -10E6, -10E6A1, and -10E7 turbofan engines,
with main fuel pump (MFP) part number (P/N) 2043M12P03 or P/N
2043M12P04, installed. These engines are installed on, but not
limited to, Embraer ERJ 190-100-STD, ERJ 190-100-LR, and ERJ 190-
100-IGW airplanes.
Unsafe Condition
(d) This AD results from GE determining that the cause of MFP
fuel strainer failure is a design problem with the strainer. We are
issuing this AD to prevent engine in-flight shutdown due to MFP
malfunctions.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified unless the
actions have already been done.
MFP Removal and Installation
(f) Not later than April 30, 2007, remove MFPs, P/N 2043M12P03
and 2043M12P04, from service and install a serviceable MFP.
Definition
(g) For the purpose of this AD, a serviceable MFP is one that
does not have P/N 2043M12P03 or 2043M12P04.
Recommended Actions
(h) We recommend that operators avoid performing the actions in
this AD on both
[[Page 1951]]
engines installed on the same airplane at the same time, if at all
possible.
Alternative Methods of Compliance
(i) The Manager, Engine Certification Office, FAA, has the
authority to approve alternative methods of compliance for this AD
