ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD),
which applies to all Bombardier Model
CL–600–2B19 series airplanes. That AD
currently requires revising the airplane
flight manual (AFM) to provide the
flightcrew with operating limitations
and procedures to enable them to
maintain controllability of the airplane
in the event that aileron control stiffness
is encountered during flight. This new
AD requires revising the Airworthiness

Federal Register / Vol. 70, No. 169 / Thursday, September 1, 2005 / Rules and Regulations
Limitations section of the Instructions of
Continued Airworthiness to incorporate
certain repetitive tasks for the aileron
control system and requires a briefing to
advise flightcrews that certain aileron
control checks are no longer required.
After accomplishing the applicable
initial tasks, the existing AFM revisions
for the aileron control check may be
removed from the AFM. This AD results
from the development of terminating
actions for the AFM revisions. We are
issuing this AD to prevent aileron
control stiffness during flight, which
could result in reduced or possible loss
of controllability of the airplane.
DATES: This AD becomes effective
October 6, 2005.
The Director of the Federal Register
approved the incorporation by reference
of Canadair Regional Jet Temporary
Revision 2B–2068, dated December 13,
2004, listed in the AD as of October 6,
2005.
The Director of the Federal Register
approved the incorporation by reference
of Canadair Regional Jet TR RJ/109–2,
dated August 9, 2002, as of October 10,

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the airworthiness
directive (AD) docket on the Internet at
https://dms.dot.gov or in person at the
Docket Management Facility office
between 9 a.m. and 5 p.m., Monday
through Friday, except Federal holidays.

(telephone (800) 647–5227) is located on
the plaza level of the Nassif Building at
the street address stated in the
ADDRESSES section.
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that
supersedes AD 2002–19–07, amendment
39–12887 (67 FR 60117, September 25,
2002). The existing AD applies to all
52007
Bombardier Model CL–600–2B19 series
airplanes. That NPRM was published in
the Federal Register on June 22, 2005
(70 FR 36067). That NPRM proposed to
retain the requirements of the existing
AD (i.e., airplane flight manual (AFM)
revisions). That NPRM also proposed to
require revising the Airworthiness
Limitations section of the Instructions of
Continued Airworthiness to incorporate
certain repetitive tasks for the aileron
control system and briefing flightcrews
that certain aileron control checks are
no longer required. After accomplishing
the applicable initial tasks, the existing
AFM revisions for the aileron control
check may be removed from the AFM.
Comments
We provided the public the
opportunity to participate in the
development of this AD. No comments
have been received on the NPRM 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.

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

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

Applicability
(c) This AD applies to all Bombardier
Model CL–600–2B19 (Regional Jet series 100
& 440) airplanes, certificated in any category.
Note 1: This AD requires revisions to
certain operator maintenance documents to
include new inspections. Compliance with
these inspections is required by 14 CFR
91.403(c). For airplanes that have been
previously modified, altered, or repaired in
the areas addressed by these inspections, the
operator may not be able to accomplish the
inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c),
the operator must request approval for an
alternative method of compliance according
(f) Within 14 days after October 10, 2002
(the effective date of AD 2002–19–07), insert
the procedures for aileron system jams
specified in Canadair Regional Jet Temporary
Revision (TR) RJ/109–2, dated August 9,
2002, into the Emergency Procedures and
Abnormal Procedures Sections, as applicable,
of the FAA-approved Canadair Regional Jet
AFM.
(g) Upon the accumulation of 5,000 total
flight hours, or within 14 days after October
10, 2002, whichever occurs later, insert the
procedures for the aileron control check
specified in Canadair Regional Jet TR RJ/109–
2, dated August 9, 2002, into the Limitations
and Normal Procedures Sections, as
applicable, of the Canadair Regional Jet AFM.
Note 2: The Limitations and Normal
Procedures specified by paragraph (g) of this
AD are required to be implemented only
when an airplane has accumulated 5,000
total flight hours. However, individual pilots
may operate other airplanes that have not yet
accumulated 5,000 total flight hours, and that
are not subject to those limitations and
procedures. Therefore, to avoid any
confusion or misunderstanding, it is
important that airlines have communication
mechanisms in place to ensure that pilots are
aware, for each flight, whether the
Limitations and Normal Procedures apply.
(h) When the information in Canadair
Regional Jet TR RJ/109–2, dated August 9,
2002, of the Canadair Regional Jet AFM, has
been incorporated into the FAA-approved
general revisions of the AFM, the TR may be
removed from the AFM.

AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD),
which applies to certain Bombardier
Model CL–215–1A10 and CL–215–6B11
series airplanes. That AD currently
requires repetitive ultrasonic
inspections to detect cracking of the
lower caps of the wing front spar and
rear spar, and corrective action if
necessary. This new AD reduces the
threshold to do the initial inspections
and revises the repetitive inspection
interval. This new AD also adds a
repetitive ultrasonic inspection of the
wing lower skin. This AD results from
reports of cracks in the front and rear
spar lower caps. We are issuing this AD
to detect and correct cracking of the
lower caps of the wing front spar and
rear spar, which could result in reduced
structural integrity of the airplane.

Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that
supersedes AD 98–04–08, amendment
39–10321 (63 FR 7640, February 17,
1998). The existing AD applies to
certain Bombardier Model CL–215–
1A10 and CL–215–6B11 series
airplanes. That NPRM was published in
the Federal Register on June 22, 2005
(70 FR 36075). That NPRM proposed to
continue to require repetitive ultrasonic
inspections to detect cracking of the
lower caps of the wing front spar and
rear spar, and corrective action if
necessary. That NPRM also proposed to
require reducing the threshold in the
existing AD for doing the initial
inspections and revising the repetitive

Comments
We provided the public the
opportunity to participate in the
development of this AD. No comments
have been received on the NPRM or on
the determination of the cost to the
public.
Explanation of Change in Applicability
We have revised the applicability of
the final rule to identify model
designations as published in the most
recent type certificate data sheet for the
affected models.
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 3 airplanes of
U.S. registry.
The actions that are required by AD
98–04–08 and retained in this AD take
about 16 work hours per airplane, at an
average labor rate of $65 per work hour.
Based on these figures, the estimated
cost of the currently required actions is
$1,040 per airplane, per inspection
cycle.
The new inspections required by this
AD will 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 new
inspections specified in this AD for U.S.
operators is $195 per inspection cycle,
or $65 per airplane, per inspection
cycle.
Authority for This Rulemaking

Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional
Jet Series 100 & 440) Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to all Bombardier Model CL-600-2B19 series
airplanes. That AD currently requires revising the airplane flight
manual (AFM) to provide the flightcrew with operating limitations and
procedures to enable them to maintain controllability of the airplane
in the event that aileron control stiffness is encountered during
flight. This new AD requires revising the Airworthiness
[[Page 52007]]
Limitations section of the Instructions of Continued Airworthiness to
incorporate certain repetitive tasks for the aileron control system and
requires a briefing to advise flightcrews that certain aileron control
checks are no longer required. After accomplishing the applicable
initial tasks, the existing AFM revisions for the aileron control check
may be removed from the AFM. This AD results from the development of
terminating actions for the AFM revisions. We are issuing this AD to
prevent aileron control stiffness during flight, which could result in
reduced or possible loss of controllability of the airplane.
DATES: This AD becomes effective October 6, 2005.
The Director of the Federal Register approved the incorporation by
reference of Canadair Regional Jet Temporary Revision 2B-2068, dated
December 13, 2004, listed in the AD as of October 6, 2005.
The Director of the Federal Register approved the incorporation by
reference of Canadair Regional Jet TR RJ/109-2, dated August 9, 2002,
as of October 10, 2002 (67 FR 60117, September 25, 2002).

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that supersedes AD 2002-19-07, amendment
39-12887 (67 FR 60117, September 25, 2002). The existing AD applies to
all Bombardier Model CL-600-2B19 series airplanes. That NPRM was
published in the Federal Register on June 22, 2005 (70 FR 36067). That
NPRM proposed to retain the requirements of the existing AD (i.e.,
airplane flight manual (AFM) revisions). That NPRM also proposed to
require revising the Airworthiness Limitations section of the
Instructions of Continued Airworthiness to incorporate certain
repetitive tasks for the aileron control system and briefing
flightcrews that certain aileron control checks are no longer required.
After accomplishing the applicable initial tasks, the existing AFM
revisions for the aileron control check may be removed from the AFM.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been received on the NPRM 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
The following table provides the estimated costs for U.S. operators
to comply with this AD.

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.

reference, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
[[Page 52008]]
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
removing amendment 39-12887 (67 FR 60117, September 25, 2002) and by
adding the following new airworthiness directive (AD):
2005-18-06 Bombardier, Inc. (Formerly Canadair): Amendment 39-14246.
Docket No. FAA-2005-21599; Directorate Identifier 2005-NM-036-AD.
Effective Date
(a) This AD becomes effective October 6, 2005.
Affected ADs
(b) This AD supersedes AD 2002-19-07.
Applicability
(c) This AD applies to all Bombardier Model CL-600-2B19
(Regional Jet series 100 & 440) airplanes, certificated in any
category.
Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (m) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued damage tolerance of the affected structure. The FAA
has provided guidance for this determination in Advisory Circular
(AC) 25-1529.
Unsafe Condition
(d) This AD was prompted by the development of terminating
actions for the airplane flight manual (AFM) revisions. We are
issuing this AD to prevent aileron control stiffness during flight,
which could result in the reduction or possible loss of
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.
Requirements of AD 2002-19-07
AFM Revisions
(f) Within 14 days after October 10, 2002 (the effective date of
AD 2002-19-07), insert the procedures for aileron system jams
specified in Canadair Regional Jet Temporary Revision (TR) RJ/109-2,
dated August 9, 2002, into the Emergency Procedures and Abnormal
Procedures Sections, as applicable, of the FAA-approved Canadair
Regional Jet AFM.
(g) Upon the accumulation of 5,000 total flight hours, or within
14 days after October 10, 2002, whichever occurs later, insert the
procedures for the aileron control check specified in Canadair
Regional Jet TR RJ/109-2, dated August 9, 2002, into the Limitations
and Normal Procedures Sections, as applicable, of the Canadair
Regional Jet AFM.
Note 2: The Limitations and Normal Procedures specified by
paragraph (g) of this AD are required to be implemented only when an
airplane has accumulated 5,000 total flight hours. However,
individual pilots may operate other airplanes that have not yet
accumulated 5,000 total flight hours, and that are not subject to
those limitations and procedures. Therefore, to avoid any confusion
or misunderstanding, it is important that airlines have
communication mechanisms in place to ensure that pilots are aware,
for each flight, whether the Limitations and Normal Procedures
apply.
(h) When the information in Canadair Regional Jet TR RJ/109-2,
dated August 9, 2002, of the Canadair Regional Jet AFM, has been
incorporated into the FAA-approved general revisions of the AFM, the
TR may be removed from the AFM.
New Actions Required by This AD
Revision of Airworthiness Limitations (AWL) Section
(i) Within 60 days after the effective date of this AD, revise
the AWL section of the Instructions of Continued Airworthiness by
incorporating the tasks specified in Table 1 of this AD and the
corresponding ``Task Threshold/Interval'' of Canadair Regional Jet
TR 2B-2068, dated December 13, 2004, into Appendix B--Airworthiness
Limitations of Part 2 of Canadair Regional Jet Model CL-600-2B19
Maintenance Requirements Manual. Thereafter, except as provided in
paragraph (m) of this AD, no alternative lubrication/replacement
intervals may be approved for the aileron control system. After
accomplishing the applicable initial tasks, the AFM revisions for
the aileron control check required by paragraph (g) of this AD and
allowed by paragraph (h) of this AD may be removed from the AFM.
