(P/N) 145–51249–001. However, the
service bulletins specify that the APU
firewall upper frame may have P/N 145–
51249–001 or 120–10731–001. APU
firewall upper frames having either part
number are subject to the identified
unsafe condition. Therefore, this
proposed AD would require modifying
the APU firewall upper frame, P/N 145–
51249–001 or 120–10731–001.
These differences have been
coordinated with the DAC.
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 and placed it in the
AD docket. See the ADDRESSES section
for a location to examine the regulatory
evaluation.
Costs of Compliance
This proposed AD would affect about
620 airplanes of U.S. registry. The
proposed actions would take about 1
work hour per airplane, at an average
labor rate of $65 per work hour. Based
on these figures, the estimated cost of
the proposed AD for U.S. operators is
$40,300, or $65 per airplane.
The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
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. Will not have a significant
economic impact, positive or negative,

SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Saab Model SAAB 2000
airplanes. This proposed AD would
require modifying the manual featherand-unfeather system for the propellers
to make the design of the system more
robust. This proposed AD results from
reports of in-flight engine shutdown
caused by uncommanded operation of
the feather pump of the propeller. We
are proposing this AD to prevent
uncommanded feathering of the
propeller, which could result in the
shutdown of an engine during flight and
consequent reduced controllability of
the airplane.

Discussion
The Luftfartsstyrelsen (LFS), which is
the airworthiness authority for Sweden,
notified us that an unsafe condition may
exist on certain Saab Model SAAB 2000
airplanes. The LFS has received reports
of in-flight engine shutdown due to
uncommanded operation of the feather
pump of the propeller, which caused
the propeller to feather. The
uncommanded activation of the feather
pump has been attributed to an
uncommanded operation of the remote
control circuit breaker (RCCB) within
the manual feather-and-unfeather
system. This condition, if not corrected,
could result in the shutdown of an
engine during flight and consequent
reduced controllability of the airplane.
Relevant Service Information
Saab has issued Service Bulletin
2000–61–006, Revision 01, dated
February 17, 2005. The service bulletin
describes procedures for modifying the
manual feather-and-unfeather system for
the propellers to make the design of the
system more robust. The modification
involves replacing the RCCBs with
relays, installing new wiring, and
making associated structural
modifications to the left and right wing
fairings. Accomplishing the actions
specified in the service information is
intended to adequately address the
unsafe condition. The LFS mandated
the service information and issued
Swedish airworthiness directive 1–198,
dated February 14, 2005, to ensure the
continued airworthiness of these
airplanes in Sweden.
FAA’s Determination and Requirements
of the Proposed AD
This airplane model is manufactured
in Sweden and is type certificated for
operation in the United States under the
provisions of section 21.29 of the
Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral
airworthiness agreement. Pursuant to
PO 00000
Frm 00006
Fmt 4702
Sfmt 4702
this bilateral airworthiness agreement,
the LFS has kept the FAA informed of
the situation described above. We have
examined the LFS’s findings, evaluated
all pertinent information, and
determined that we need to issue an AD
for airplanes of this type design that are
certificated for operation in the United
States.
Therefore, we are proposing this AD,
which would require accomplishing the
actions specified in the service
information described previously.
Costs of Compliance
This proposed AD would affect about
3 airplanes of U.S. registry. The
proposed actions would take about 50
work hours per airplane, at an average
labor rate of $65 per work hour.
Required parts would cost about
$13,571 per airplane. Based on these
figures, the estimated cost of the
proposed AD for U.S. operators is
$50,463, or $16,821 per airplane.
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

Federal Register / Vol. 70, No. 169 / Thursday, September 1, 2005 / Proposed Rules
3. Will not have a significant

Flexibility Act.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket. See the ADDRESSES section
for a location to examine the regulatory
evaluation.

SUMMARY: The FAA proposes to
supersede an existing airworthiness
directive (AD) that was issued for
General Electric Company (GE) CF34–
3A1 and –3B1 series turbofan engines
with certain part numbers (P/Ns) and
serial numbers (SNs) of stage 5 low
pressure turbine (LPT) disks and stage 6
LPT disks. These engines are installed
in Bombardier Canadair CL600–2B19
Regional Jet (RJ) airplanes. This
proposed AD would add SNs to the
affected disk population for RJ
airplanes. This proposed AD would also
add GE CF34–1 and –3 series turbofan
engines with certain P/Ns and SNs of
stage 5 LPT disks and stage 6 LPT disks,
to the applicability section. These
engines are installed in Bombardier
Canadair models CL–600–2A12 (CL–
601), CL–600–2B16 (CL–601–3A), (CL–
601–3R), and (CL–604) Business Jet (BJ)
PO 00000
Frm 00007

airplanes. This proposed AD would
require initial and repetitive visual and
eddy current inspections (ECI) of the
affected disk population. This proposed
AD would also allow replacement of
those disks as optional terminating
action to the repetitive inspections.
Also, this proposed AD would require
eventual replacement of the affected
disks as terminating action to the
repetitive inspections. This proposed
AD results from the discovery of
additional suspect stage 5 LPT disks and
stage 6 LPT disks. These disks could fail
due to low-cycle fatigue cracking that
may start at the site of an electrical arcout on the disk. We are proposing this
AD to prevent low-cycle-fatigue (LCF)
failure of stage 5 LPT disks and stage 6
LPT disks, which could lead to
uncontained engine failure.

Discussion
The Luftfartsstyrelsen (LFS), which is the airworthiness authority
for Sweden, notified us that an unsafe condition may exist on certain
Saab Model SAAB 2000 airplanes. The LFS has received reports of in-
flight engine shutdown due to uncommanded operation of the feather pump
of the propeller, which caused the propeller to feather. The
uncommanded activation of the feather pump has been attributed to an
uncommanded operation of the remote control circuit breaker (RCCB)
within the manual feather-and-unfeather system. This condition, if not
corrected, could result in the shutdown of an engine during flight and
consequent reduced controllability of the airplane.
Relevant Service Information
Saab has issued Service Bulletin 2000-61-006, Revision 01, dated
February 17, 2005. The service bulletin describes procedures for
modifying the manual feather-and-unfeather system for the propellers to
make the design of the system more robust. The modification involves
replacing the RCCBs with relays, installing new wiring, and making
associated structural modifications to the left and right wing
fairings. Accomplishing the actions specified in the service
information is intended to adequately address the unsafe condition. The
LFS mandated the service information and issued Swedish airworthiness
directive 1-198, dated February 14, 2005, to ensure the continued
airworthiness of these airplanes in Sweden.
FAA's Determination and Requirements of the Proposed AD
This airplane model is manufactured in Sweden and is type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the LFS has kept the FAA informed of
the situation described above. We have examined the LFS's findings,
evaluated all pertinent information, and determined that we need to
issue an AD for airplanes of this type design that are certificated for
operation in the United States.
Therefore, we are proposing this AD, which would require
accomplishing the actions specified in the service information
described previously.
Costs of Compliance
This proposed AD would affect about 3 airplanes of U.S. registry.
The proposed actions would take about 50 work hours per airplane, at an
average labor rate of $65 per work hour. Required parts would cost
about $13,571 per airplane. Based on these figures, the estimated cost
of the proposed AD for U.S. operators is $50,463, or $16,821 per
airplane.
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
[[Page 52043]]
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 regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.
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:
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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
Saab Aircraft AB: Docket No. FAA-2005-22255; Directorate Identifier
2005-NM-106-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by October
3, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to SAAB Model SAAB 2000 airplanes,
certificated in any category, serial numbers -004 through -063
inclusive.
Unsafe Condition
(d) This AD results from reports of in-flight engine shutdown
caused by uncommanded operation of the feather pump of the
propeller. We are issuing this AD to prevent uncommanded feathering
of the propeller, which could result in the shutdown of an engine
during flight and consequent reduced controllability of the
airplane.
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.
Modification
(f) Within 12 months after the effective date of this AD, modify
the manual feather-and-unfeather system of the propellers by doing
all actions specified in the Accomplishment Instructions of Saab
Service Bulletin 2000-61-006, Revision 01, dated February 17, 2005.
Actions Accomplished Previously
(g) A modification accomplished before the effective date of
this AD in accordance with Saab Service Bulletin 2000-61-006, dated
December 20, 2004, is acceptable for compliance with paragraph (f)
of this AD.
Alternative Methods of Compliance (AMOCs)
(h) The Manager, International Branch, ANM-116, Transport
Airplane Directorate, FAA, has the authority to approve AMOCs for
this AD, if requested in accordance with the procedures found in 14
CFR 39.19.
Related Information
(i) Swedish airworthiness directive 1-198, dated February 14,
2005, also addresses the subject of this AD.
Issued in Renton, Washington, on August 24, 2005.
