(NPRM).
AGENCY:
SUMMARY: The FAA proposes to
supersede an existing airworthiness
directive (AD) that applies to all
Bombardier Model CL–600–2B19 series
airplanes. The existing 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
proposed AD would revise the

to incorporate certain repetitive tasks for
the aileron control system and would
require a briefing to advise flight crews
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 proposed AD is prompted by the
development of terminating actions for
the AFM revisions. We are proposing
this AD to prevent aileron control
stiffness during flight, which could
result in reduced or possible loss of
controllability of the airplane.

Discussion
On September 16, 2002, we issued AD
2002–19–07, amendment 39–12887 (67
FR 60117, September 25, 2002), for all
Bombardier Model CL–600–2B19 series
airplanes. That AD requires revising the
Canadair Regional Jet 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. That AD was
prompted by a significant number of
reports of aileron control stiffness. We
issued that AD to prevent aileron
control stiffness during flight, which
could result in the reduction or possible
loss of controllability of the airplane.
Actions Since Existing AD Was Issued
Since we issued AD 2002–19–07,
Transport Canada Civil Aviation
(TCCA), which is the airworthiness
authority for Canada, issued Canadian
airworthiness directive CF–2002–35R2
on January 6, 2005 (CF–2002–35R1,
dated August 16, 2002, was referenced
in AD 2002–19–07). TCCA mandated
the service information described below
and a briefing to advise flight crews that
aileron control checks are no longer
required to ensure the continued
airworthiness of the affected airplanes
in Canada.
The airplane manufacturer has issued
Canadair Regional Jet Temporary
Revision (TR) 2B–2068, dated December
13, 2004, which describes, among
others, the tasks specified in the
following table. Accomplishing the
applicable initial tasks eliminates the
need for the AFM revisions for the
aileron control check required by AD
2002–19–07. The compliance time for
the applicable initial tasks range
between 1,000 flight hours and 10,500
flight hours.

FAA’s Determination and Requirements
of the Proposed AD
This airplane model is manufactured
in Canada 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,
TCCA has kept the FAA informed of the
situation described above. We have
examined TCCA’s findings, evaluated
all pertinent information, and
determined that AD action is necessary
for airplanes of this type design that are
certificated for operation in the United
States.
This proposed AD would supersede
AD 2002–19–07. This proposed AD
would retain the requirements of the

existing AD (i.e., AFM revisions). This
proposed AD would also require
revising the Airworthiness Limitations
(AWL) section of the Instructions of
Continued Airworthiness to incorporate
certain repetitive tasks for the aileron
control system specified in Canadair
Regional Jet TR 2B–2068 described
previously. After accomplishing the
applicable initial tasks, the AFM
revisions for the aileron control checks
required by AD 2002–19–07 may be
removed from the AFM.
2002–19–07 (paragraph (g) of this
proposed AD). We have determined that
the following sentence in paragraph (i)
of the proposed AD would accomplish
the intent of the Canadian airworthiness
directive: ‘‘After accomplishing the
applicable initial tasks, the AFM
revisions required by paragraph (g) of
this AD and allowed by paragraph (h) of
this AD may be removed from the
AFM.’’ We have coordinated this
difference with TCCA.
Difference Between the Proposed AD
and Canadian Airworthiness Directive
Canadian airworthiness directive CF–
2002–35R2 mandates revising the AFM
by inserting a copy of the changes
specified in Canadair Regional Jet TR
RJ/142, dated August 16, 2004, into
AFM CSP A–012. The TR specifies to
delete the aileron control check and
procedures covering suspected frozen
ailerons, which were incorporated by
the AFM revisions required by 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
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,
on a substantial number of small entities

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.
§ 39.13
[Amended]
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.
2. The FAA amends § 39.13 by
removing amendment 39–12887 (67 FR
60117, September 25, 2002) and adding
the following new airworthiness
directive (AD):
Compliance

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

AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain McDonnell Douglas transport
category airplanes. This proposed AD
would require an inspection of the
torque tube assembly for the rudder
pedal for cracking; an inspection of the
torque tube assembly to determine the
thickness of the torque tube wall, if
necessary; and replacing the rudder
torque tube with a new or serviceable
rudder torque tube, if necessary. This
proposed AD is prompted by a report of
a broken rudder pedal torque tube. We
are proposing this AD to prevent failure
of a rudder pedal torque tube, which
could result in loss of rudder control
and nose wheel steering controlled by

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede an existing airworthiness
directive (AD) that applies to all Bombardier Model CL-600-2B19 series
airplanes. The existing 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 proposed AD would revise the
Airworthiness Limitations section of the Instructions of Continued
Airworthiness to incorporate certain repetitive tasks for the aileron
control system and would require a briefing to advise flight crews 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
proposed AD is prompted by the development of terminating actions for
the AFM revisions. We are proposing this AD to prevent aileron control
stiffness during flight, which could result in reduced or possible loss
of controllability of the airplane.
DATES: We must receive comments on this proposed AD by July 22, 2005.

Discussion
On September 16, 2002, we issued AD 2002-19-07, amendment 39-12887
(67 FR 60117, September 25, 2002), for all Bombardier Model CL-600-2B19
series airplanes. That AD requires revising the Canadair Regional Jet
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. That AD was prompted by a significant number
of reports of aileron control stiffness. We issued that AD to prevent
aileron control stiffness during flight, which could result in the
reduction or possible loss of controllability of the airplane.
Actions Since Existing AD Was Issued
Since we issued AD 2002-19-07, Transport Canada Civil Aviation
(TCCA), which is the airworthiness authority for Canada, issued
Canadian airworthiness directive CF-2002-35R2 on January 6, 2005 (CF-
2002-35R1, dated August 16, 2002, was referenced in AD 2002-19-07).
TCCA mandated the service information described below and a briefing to
advise flight crews that aileron control checks are no longer required
to ensure the continued airworthiness of the affected airplanes in
Canada.
The airplane manufacturer has issued Canadair Regional Jet
Temporary Revision (TR) 2B-2068, dated December 13, 2004, which
describes, among others, the tasks specified in the following table.
Accomplishing the applicable initial tasks eliminates the need for the
AFM revisions for the aileron control check required by AD 2002-19-07.
The compliance time for the applicable initial tasks range between
1,000 flight hours and 10,500 flight hours.
Table--Affected Task Numbers
----------------------------------------------------------------------------------------------------------------
Task No. Description
----------------------------------------------------------------------------------------------------------------
R22-11-A083-01................................................................ Lubrication of aileron autopilot
servo and servo mount engage
clutch faces.
R27-00-A053-01................................................................ Replacement of the aileron
control pulleys with new or
serviceable parts.
R27-11-A082-01................................................................ Lubrication of the aileron
control cables at the wing
pulley interfaces.
R27-11-A082-02................................................................ Lubrication of the aileron rear
quadrant and trim lever
bearings.
----------------------------------------------------------------------------------------------------------------
Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition.
FAA's Determination and Requirements of the Proposed AD
This airplane model is manufactured in Canada 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, TCCA has kept the FAA informed of
the situation described above. We have examined TCCA's findings,
evaluated all pertinent information, and determined that AD action is
necessary for airplanes of this type design that are certificated for
operation in the United States.
This proposed AD would supersede AD 2002-19-07. This proposed AD
would retain the requirements of the existing AD (i.e., AFM revisions).
This proposed AD would also require revising the Airworthiness
Limitations (AWL) section of the Instructions of Continued
Airworthiness to incorporate certain repetitive tasks for the aileron
control system specified in Canadair Regional Jet TR 2B-2068 described
previously. After accomplishing the applicable initial tasks, the AFM
revisions for the aileron control checks required by AD 2002-19-07 may
be removed from the AFM.
Difference Between the Proposed AD and Canadian Airworthiness Directive
Canadian airworthiness directive CF-2002-35R2 mandates revising the
AFM by inserting a copy of the changes specified in Canadair Regional
Jet TR RJ/142, dated August 16, 2004, into AFM CSP A-012. The TR
specifies to delete the aileron control check and procedures covering
suspected frozen ailerons, which were incorporated by the AFM revisions
required by AD 2002-19-07 (paragraph (g) of this proposed AD). We have
determined that the following sentence in paragraph (i) of the proposed
AD would accomplish the intent of the Canadian airworthiness directive:
``After accomplishing the applicable initial tasks, the AFM revisions
required by paragraph (g) of this AD and allowed by paragraph (h) of
this AD may be removed from the AFM.'' We have coordinated this
difference with TCCA.
Clarification of Compliance Times Specified in Service Information
Canadair Regional Jet TR 2B-2068 recommends accomplishing the
applicable initial tasks no later than the applicable compliance time
``from November 5, 2004.'' This proposed AD would require accomplishing
the task within the applicable compliance time ``after the effective
date of this AD.''
[[Page 36069]]
Change to Existing AD
This proposed AD would retain all requirements of AD 2002-19-07.
Since AD 2002-19-07 was issued, the AD format has been revised, and
certain paragraphs have been rearranged. As a result, the corresponding
paragraph identifiers have changed in this proposed AD, as listed in
the following table:

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, 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.
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 FAA amends Sec. 39.13 by removing amendment 39-12887 (67 FR
60117, September 25, 2002) and adding the following new airworthiness
directive (AD):
Bombardier, Inc. (Formerly Canadair): Docket No. FAA-2005-21599;
Directorate Identifier 2005-NM-036-AD.
Comments Due Date
(a) The Federal Aviation Administration must receive comments on
this AD action by July 22, 2005.
Affected ADs
(b) This AD supersedes AD 2002-19-07, amendment 39-12887 (67 FR
60117, September 25, 2002).
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
[[Page 36070]]
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.
Table 1.--Affected Task Numbers
----------------------------------------------------------------------------------------------------------------
Task No. Description

control cables at the wing
pulley interfaces.
(4) R27-11-A082-02............................................................ Lubrication of the aileron rear
quadrant and trim lever
bearings.
----------------------------------------------------------------------------------------------------------------
(j) For airplanes that have exceeded the task threshold for the
new tasks specified in paragraph (i) of this AD as of the effective
date of this AD: Do the initial tasks at the applicable ``Phase-In''
time specified in Canadair Regional Jet TR 2B-2068, dated December
13, 2004; except where the TR specifies accomplishing the task no
later than the applicable compliance time ``from November 5, 2004,''
this AD requires accomplishing the task within the applicable
compliance time ``after the effective date of this AD.''
(k) When the information in Canadair Regional Jet TR 2B-2068,
dated December 13, 2004, is included in the general revisions of the
Maintenance Requirements Manual, this TR may be removed.
Flight Crew Briefing
(l) After accomplishing the applicable initial tasks required by
paragraph (i) of this AD, brief flight crews that there is no longer
a requirement to perform aileron control checks following takeoff
from a wet or contaminated runway.
Alternative Methods of Compliance (AMOCs)
(m) The Manager, New York Aircraft Certification Office (ACO),
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
(n) Canadian airworthiness directive CF-2002-35R2, issued
