ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Bombardier Model CL–600–1A11 (CL–
600), CL–600–2A12 (CL–601), and CL–
600–2B16 (CL–601–3A, CL–601–3R, and
CL–604) airplanes. This AD requires
inspecting to identify the part number
and serial number of the selector valves
of the nose landing gear (NLG) and the
nose gear door, and doing related
investigative and corrective actions if
necessary. This AD results from reports
of uncommanded partial retractions of
the NLG. We are issuing this AD to
prevent internal leakage of the selector
valve, which, under certain conditions,
could result in an uncommanded
retraction of the NLG with consequent
damage to the airplane and possible
serious injury to ground personnel.
DATES: This AD becomes effective
August 16, 2007.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of August 16, 2007.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the AD docket on
the Internet at https://dms.dot.gov or in
person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday
through Friday, except Federal holidays.
The Docket Operations office (telephone
(800) 647–5527) is located on the
ground floor of the West Building at the
street address stated in the ADDRESSES
section.
Discussion
The FAA issued a supplemental
notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an
AD that would apply to certain
Bombardier Model CL–600–1A11 (CL–
600), CL–600–2A12 (CL–601), and CL–
600–2B16 (CL–601–3A, CL–601–3R, and
CL–604) airplanes. That supplemental
NPRM was published in the Federal
Register on April 26, 2007 (72 FR
20777). That supplemental NPRM
proposed to require inspecting to
identify the part number and serial
number of the selector valves of the
nose landing gear (NLG) and the nose
gear door, and doing related
investigative and corrective actions if
necessary. That supplemental NPRM
also proposed to add airplanes to the
applicability.
Comments
We provided the public the
opportunity to participate in the
development of this AD. No comments
have been received on the supplemental
NPRM or on the determination of the
cost to the public.
Clarification of Alternative Method of
Compliance (AMOC) Paragraph
We have revised this action to clarify
the appropriate procedure for notifying
the principal inspector before using any
approved AMOC on any airplane to
which the AMOC applies.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD with the change
described previously. We have
determined that this change will neither
increase the economic burden on any

operator nor increase the scope of the
AD.
Costs of Compliance
This AD affects about 502 airplanes of
U.S. registry.
The inspection to determine the
manufacturer part number and serial
number of the selector valve(s) takes
about 1 work hour per airplane, at an
average labor rate of $80 per work hour.
Based on these figures, the estimated
cost of the required inspection for U.S.
operators is $40,160, or $80 per
airplane.
The general visual inspection of the
selector valve(s), if accomplished, takes
about 1 work hour per airplane, at an
average labor rate of $80 per work hour.
Based on these figures, the estimated
cost of that inspection for U.S. operators
is $80 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 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 regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

Discussion
The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that would apply to certain
Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-

inspecting to identify the part number and serial number of the
selector valves of the nose landing gear (NLG) and the nose gear door,
and doing related investigative and corrective actions if necessary.
That supplemental NPRM also proposed to add airplanes to the
applicability.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been received on the
supplemental NPRM or on the determination of the cost to the public.
Clarification of Alternative Method of Compliance (AMOC) Paragraph
We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD with the
change described previously. We have determined that this change will
neither increase the economic burden on any
[[Page 38005]]
operator nor increase the scope of the AD.
Costs of Compliance
This AD affects about 502 airplanes of U.S. registry.
The inspection to determine the manufacturer part number and serial
number of the selector valve(s) takes about 1 work hour per airplane,
at an average labor rate of $80 per work hour. Based on these figures,
the estimated cost of the required inspection for U.S. operators is
$40,160, or $80 per airplane.
The general visual inspection of the selector valve(s), if
accomplished, takes about 1 work hour per airplane, at an average labor
rate of $80 per work hour. Based on these figures, the estimated cost
of that inspection for U.S. operators is $80 per airplane.

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

Unsafe Condition
(d) This AD results from reports of uncommanded partial
retractions of the nose landing gear (NLG). We are issuing this AD
to prevent internal leakage of the selector valve, which, under
certain conditions, could result in an uncommanded retraction of the
NLG with consequent damage to the airplane and possible serious
injury to ground personnel.
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.
Inspection and Corrective Actions
(f) Within 500 flight hours or 12 months after the effective
date of this AD, whichever occurs first, inspect to determine the
manufacturer part numbers (P/Ns) and serial numbers of the selector
valves of the NLG and nose gear door. A review of airplane
maintenance records is acceptable in lieu of this inspection if the
serial numbers of the selector valves can be conclusively determined
from that review. For any subject selector valve having Tactair
Fluid Controls P/N 750006000 and a S/N from 0001 through 0767
inclusive, before further flight, do related investigative
(including a general visual inspection for proper installation of
the lock wire of the end cap) and corrective actions; in accordance
with the applicable service bulletin identified in Table 1 of this
AD.
Note 1: Operators should be aware that selector valves having
Bombardier P/N 601R75146-1 may be supplied by different
manufacturers and have different manufacturer part numbers. Only
airplanes having selector valves manufactured by Tactair Fluid
Controls, having P/N 750006000, are subject to the investigative and
corrective actions specified in paragraph (f) of this AD.
Note 2: For the purposes of this AD, a general visual inspection
is: ``A visual examination of an interior or exterior area,
installation, or assembly to detect obvious damage, failure, or
irregularity. This level of inspection is made from within touching
distance unless otherwise specified. A mirror may be necessary to
ensure visual access to all surfaces in the inspection area. This
level of inspection is made under normally available lighting
conditions such as daylight, hangar lighting, flashlight, or
[[Page 38006]]
droplight and may require removal or opening of access panels or
doors. Stands, ladders, or platforms may be required to gain
proximity to the area being checked.''
Note 3: The service bulletins identified in Table 1 of this AD
refer to Tactair Fluid Controls Service Bulletin SB750006000-1,
Revision A, dated September 6, 2005, as an additional source of
service information for doing the related investigative and
corrective actions required by this AD.
Actions Accomplished According to Previous Issue of Service Bulletin
(g) Actions accomplished before the effective date of this AD in
accordance with Bombardier Service Bulletin 604-32-021, Revision 01,
dated February 20, 2006 (for Model CL-600-2B16 (CL-604) airplanes),
are considered acceptable for compliance with the corresponding
actions specified in this AD.
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, New York Aircraft Certification Office, FAA,
has the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
(2) To request a different method of compliance or a different
compliance time for this AD, follow the procedures in 14 CFR 39.19.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
