Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule.
wwhite on PROD1PC65 with RULES
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD) for
General Electric Company (GE) CF34–
1A, –3A, –3A1, –3A2, –3B, and –3B1
turbofan engines. That AD currently
requires a onetime inspection, and if
necessary replacing certain fan disks for
electrical arc-out indications. That AD
also reduces the life limit of certain fan
disks. This AD requires the same actions
and adds one disk part number (P/N)
and serial number (SN) to the affected
fan disks. This AD results from an error
in the first part number and serial
number listed in Table 1 of the original
AD. We are issuing this AD to prevent
rupture of the fan disk due to cracks that
initiate at an electrical arc-out, which
could result in an uncontained failure of
the engine.
DATES: This AD becomes effective April
7, 2006. The Director of the Federal
Register previously approved the
incorporation by reference of certain
publications listed in the regulations as
of May 31, 2001 (66 FR 27017, May 16,
2001).

Jkt 208001
Authority for This Rulemaking
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the proposal or on the
determination of the cost to the public.
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.
Conclusion
Regulatory Findings
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed.
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
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 by sending a request to us
at the address listed under ADDRESSES.
Include ‘‘AD Docket No. 2000–NE–42–
AD’’ in your request.
Examining the AD Docket
AGENCY:
VerDate Aug<31>2005
a proposed airworthiness directive (AD).
The proposed AD applies to GE CF34–
1A, –3A, –3A1, –3A2, –3B, and –3B1
turbofan engines. We published the
proposed AD in the Federal Register on
August 23, 2005 (70 FR 49215). That
action proposed to require the same
actions as AD 2001–10–03, and add one
disk P/N and SN to the affected fan
disks.
You may examine the AD Docket
(including any comments and service
information), by appointment, between
8 a.m. and 4:30 p.m., Monday through
Friday, except Federal holidays. See
ADDRESSES for the location.
Comments
Costs of Compliance
We estimate that one GE CF34–1A,
–3A, –3A1, –3A2, –3B, and –3B1
turbofan engine of U.S. registry would
be affected by this AD. We also estimate
that it will take approximately six work
hours per engine to perform the actions,
and that the average labor rate is $65 per
work hour. Required parts will cost
approximately $140,000 per engine.
Based on these figures, we estimate the
total cost of the AD to U.S. operators to
be $140,390.
Special Flight Permits Paragraph
Removed
Paragraph (f) of the current AD, AD
2001–10–03, contains a paragraph
pertaining to special flight permits.
Even though this final rule does not
contain a similar paragraph, we have
made no changes with regard to the use
of special flight permits to operate the
airplane to a repair facility to do the
work required by this AD. In July 2002,
we published a new part 39 that
contains a general authority regarding
special flight permits and airworthiness
directives; see Docket No. FAA–2004–
8460, Amendment 39–9474 (69 FR
47998, July 22, 2002). Thus, when we
now supersede ADs we will not include
a specific paragraph on special flight
permits unless we want to limit the use
of that general authority granted in
section 39.23.

SUPPLEMENTARY INFORMATION:
History
On Thursday, December 20, 2005, the
FAA proposed to amend part 71 of the
Federal Aviation Regulations (14 CFR
part 71) to modify Class E airspace
upward from 700 ft. and 1,200 ft. above
the surface at Sand Point, AK (70 FR
75438). The action was proposed in
order to create Class E airspace
sufficient in size to contain aircraft
while executing three new SIAPs, one
revised SIAP, and one revised DP for the
Sand Point Airport. The new
approaches are (1) Area Navigation

Non-directional Beacon (NDB)/Distance
Measuring Equipment (DME) RWY 13,
original; and (3) NDB/DME RWY 31,
original. The revised SIAP is the NDB
RWY 13, Amendment 1. The unnamed
revised DP is published in the front of
the U.S. Terminal Procedures Alaska
Vol 1. Class E controlled airspace
extending upward from 700 ft. and
1,200 ft. above the surface in the Sand
Point Airport area is modified by this
action. Interested parties were invited to
participate in this rulemaking
proceeding by submitting written
comments on the proposal to the FAA.
No public comments have been
received; thus the rule is adopted as
proposed.
The area will be depicted on
aeronautical charts for pilot reference.
The coordinates for this airspace docket
are based on North American Datum 83.
The Class E airspace areas designated as
700/1,200 ft. transition areas are
published in paragraph 6005 of FAA
Order 7400.9N, Airspace Designations
and Reporting Points, dated September
1, 2005, and effective September 15,
2005, which is incorporated by
reference in 14 CFR 71.1. The Class E
airspace designation listed in this
document will be published
subsequently in the Order.
The Rule
This amendment to 14 CFR part 71
modifies Class E airspace at Sand Point,
Alaska. This Class E airspace is
modified to accommodate aircraft
executing three new SIAPs, one revised
SIAP, and one revised DP, and will be
depicted on aeronautical charts for pilot
reference. The intended effect of this
rule is to provide adequate controlled
airspace for Instrument Flight Rule (IFR)
operations at Sand Point Airport, Sand
Point, Alaska.
The FAA has determined that this
regulation only involves an established
body of technical regulations for which
frequent and routine amendments are
necessary to keep them operationally
current. It, therefore—(1) is not a
‘‘significant regulatory action’’ under
Executive Order 12866; (2) is not a
‘‘significant rule’’ under DOT
Regulatory Policies and Procedures (44
PO 00000
Frm 00004
Fmt 4700
Sfmt 4700
Date
FR 11034; February 26, 1979); and (3)
does not warrant preparation of a
regulatory evaluation as the anticipated
impact is so minimal. Since this a
routine matter that will only affect air
traffic procedures and air navigation, it
is certified that this rule will not have
a significant economic impact on a
substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
The FAA’s authority to issue rules
regarding aviation safety is found in
Title 49 of the United States Code.
Subtitle 1, Section 106 describes the
authority of the FAA Administrator.
Subtitle VII, Aviation Programs,
describes in more detail the scope of the
agency’s authority.
This rulemaking is promulgated
under the authority described in
Subtitle VII, Part A, Subpart 1, Section
40103, Sovereignty and use of airspace.
Under that section, the FAA is charged
with prescribing regulations to ensure
the safe and efficient use of the
navigable airspace. This regulation is
within the scope of that authority
because it creates Class E airspace
sufficient in size to contain aircraft
executing instrument procedures for the
Sand Point Airport and represents the
FAA’s continuing effort to safely and
efficiently use the navigable airspace.

Airworthiness Directives; General Electric Company CF34 Series
Turbofan Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) for General Electric Company (GE) CF34-1A, -3A, -3A1, -3A2, -3B,
and -3B1 turbofan engines. That AD currently requires a onetime
inspection, and if necessary replacing certain fan disks for electrical
arc-out indications. That AD also reduces the life limit of certain fan
disks. This AD requires the same actions and adds one disk part number
(P/N) and serial number (SN) to the affected fan disks. This AD results
from an error in the first part number and serial number listed in
Table 1 of the original AD. We are issuing this AD to prevent rupture
of the fan disk due to cracks that initiate at an electrical arc-out,
which could result in an uncontained failure of the engine.
DATES: This AD becomes effective April 7, 2006. The Director of the
Federal Register previously approved the incorporation by reference of
certain publications listed in the regulations as of May 31, 2001 (66
FR 27017, May 16, 2001).

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed airworthiness directive (AD). The proposed AD applies
to GE CF34-1A, -3A, -3A1, -3A2, -3B, and -3B1 turbofan engines. We
published the proposed AD in the Federal Register on August 23, 2005
(70 FR 49215). That action proposed to require the same actions as AD
2001-10-03, and add one disk P/N and SN to the affected fan disks.
Examining the AD Docket
You may examine the AD Docket (including any comments and service
information), by appointment, between 8 a.m. and 4:30 p.m., Monday
through Friday, except Federal holidays. See ADDRESSES for the
location.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received no comments on the proposal or on
the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
We estimate that one GE CF34-1A, -3A, -3A1, -3A2, -3B, and -3B1
turbofan engine of U.S. registry would be affected by this AD. We also
estimate that it will take approximately six work hours per engine to
perform the actions, and that the average labor rate is $65 per work
hour. Required parts will cost approximately $140,000 per engine. Based
on these figures, we estimate the total cost of the AD to U.S.
operators to be $140,390.

Paragraph (f) of the current AD, AD 2001-10-03, contains a
paragraph pertaining to special flight permits. Even though this final
rule does not contain a similar paragraph, we have made no changes with
regard to the use of special flight permits to operate the airplane to
a repair facility to do the work required by this AD. In July 2002, we
published a new part 39 that contains a general authority regarding
special flight permits and airworthiness directives; see Docket No.
FAA-2004-8460, Amendment 39-9474 (69 FR 47998, July 22, 2002). Thus,
when we now supersede ADs we will not include a specific paragraph on
special flight permits unless we want to limit the use of that general
authority granted in section 39.23.
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 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 by
sending a request to us at the address listed under ADDRESSES. Include
``AD Docket No. 2000-NE-42-AD'' in your request.

2. The FAA amends Sec. 39.13 by removing Amendment 39-12229 (66 FR
27017, May 16, 2001) and by adding a new airworthiness directive,
Amendment 39-14501, to read as follows:
2006-05-04 General Electric Company: Amendment 39-14501. Docket No.
2000-NE-42-AD.
Effective Date
