Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for certain
Bombardier, Inc. Model CL–600–2B19
(Regional Jet Series 100 & 440)
airplanes. This proposed AD was
prompted by reports of fractured rudder
pedal tubes installed on the pilot-side
rudder bar assembly. This proposed AD
would require repetitive inspections for
cracking and damage of both pilot-side
rudder pedal tubes, and replacement of
affected pilot-side rudder bar assemblies
if necessary. We are proposing this AD
to detect and correct cracking of both
pilot-side rudder pedal tubes, which
could result in loss of pilot rudder pedal
input causing reduced yaw
controllability or a runway excursion.
DATES: We must receive comments on
this proposed AD by October 10, 2013.
ADDRESSES: You may send comments by
any of the following methods:

Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2013–12,
dated May 14, 2013 (referred to after
this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for the specified products. The MCAI
states:
There have been two in-service reports of
fracture of rudder pedal tubes installed on
the pilot-side rudder bar assembly.
Laboratory examination of the fractured
rudder pedal tubes found that in both cases,
the fatigue cracks initiated at the aft taper pin
holes where the connecting rod fitting is
attached. Fatigue testing of the rudder pedal
tubes confirmed that the fatigue cracking is
due to loads induced during parking brake
application. Therefore, only the rudder pedal
tubes on the pilot’s side are vulnerable to
fatigue cracking as the parking brake is
primarily applied by the pilot.
Loss of pilot rudder pedal input during
flight would result in reduced yaw
controllability of the aeroplane. Loss of pilot
rudder pedal input during takeoff or landing
may lead to a runway excursion.
This [Canadian] AD mandates initial and
repetitive [detailed or eddy current]
inspections [for cracking and damage and
replacement if necessary] of the pilot-side
rudder * * * [bar assembly], until the
terminating action is accomplished.
Required actions also include repairing
damage. The terminating action is
replacement of both pilot-side rudder
bar assemblies. You may obtain further
information by examining the MCAI in
the AD docket.
Relevant Service Information
Bombardier has issued Service
Bulletin 601R–27–162, including
Appendix A, dated April 5, 2013. The
actions described in this service
information are intended to correct the
unsafe condition identified in the
MCAI.
FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
E:\FR\FM\26AUP1.SGM
26AUP1
Federal Register / Vol. 78, No. 165 / Monday, August 26, 2013 / Proposed Rules
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.

ehiers on DSK2VPTVN1PROD with PROPOSALS-1
We have received no definitive data
that would enable us to provide a cost
estimate for the repair specified in this
proposed AD.
According to the manufacturer, some
of the costs of this proposed AD may be
covered under warranty, thereby
reducing the cost impact on affected
individuals. We do not control warranty
coverage for affected individuals. As a
result, we have included all costs in our
cost estimate.
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 determined that this proposed AD
would not have federalism implications
VerDate Mar<15>2010
13:45 Aug 23, 2013
Jkt 229001
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 this 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);
3. Will not affect intrastate aviation in
Alaska; and
4. 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.

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-12, dated May 14, 2013 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for the specified products. The MCAI states:
There have been two in-service reports of fracture of rudder
pedal tubes installed on the pilot-side rudder bar assembly.
Laboratory examination of the fractured rudder pedal tubes found
that in both cases, the fatigue cracks initiated at the aft taper
pin holes where the connecting rod fitting is attached. Fatigue
testing of the rudder pedal tubes confirmed that the fatigue
cracking is due to loads induced during parking brake application.
Therefore, only the rudder pedal tubes on the pilot's side are
vulnerable to fatigue cracking as the parking brake is primarily
applied by the pilot.
Loss of pilot rudder pedal input during flight would result in
reduced yaw controllability of the aeroplane. Loss of pilot rudder
pedal input during takeoff or landing may lead to a runway
excursion.

We have received no definitive data that would enable us to provide
a cost estimate for the repair specified in this proposed AD.
According to the manufacturer, some of the costs of this proposed
AD may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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 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 this 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);
3. Will not affect intrastate aviation in Alaska; and
4. 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.

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
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 FAA amends Sec. 39.13 by adding the following new AD:
Bombardier, Inc.: Docket No. FAA-2013-0700; Directorate Identifier
2013-NM-102-AD.
(a) Comments Due Date
We must receive comments by October 10, 2013.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional
Jet Series 100 & 440) airplanes, certificated in any category,
serial numbers 7003 and subsequent.
(d) Subject
Air Transport Association (ATA) of America Code 27, Flight
controls.
(e) Reason
This AD was prompted by reports of fractured rudder pedal tubes
installed on the pilot-side rudder bar assembly. We are issuing this
AD to detect and correct cracking of both pilot-side rudder pedal
tubes, which could result in loss of pilot rudder pedal input
causing reduced yaw controllability or a runway excursion.
(f) Compliance
You are responsible for having the actions required by this AD
performed within the
[[Page 52714]]
compliance times specified, unless the actions have already been
done.
(g) Initial Inspections
At the applicable time specified in paragraph (g)(1) through
(g)(6) of this AD, do a detailed or eddy current inspection for
cracking and damage (i.e., corrosion or cracking) of both pilot-side
rudder pedal tubes having part number (P/N) 600-90204-3, in
accordance with the Accomplishment Instructions of Bombardier
Service Bulletin 601R-27-162, including Appendix A, dated April 5,
2013.
(1) For airplanes that have accumulated less than 20,000 total
flight cycles as of the effective date of this AD: Do the inspection
before the accumulation of 23,000 total flight cycles.
(2) For airplanes that have accumulated 20,000 total flight
cycles or more, but less than 25,000 total flight cycles as of the
effective date of this AD: Do the inspection within 3,000 flight
cycles after the effective date of this AD, but not to exceed 26,300
total flight cycles.
(3) For airplanes that have accumulated 25,000 total flight
cycles or more, but less than 30,000 total flight cycles as of the
effective date of this AD: Do the inspection within 1,300 flight
cycles after the effective date of this AD, but not to exceed 30,800
total flight cycles.
(4) For airplanes that have accumulated 30,000 total flight
cycles or more, but less than 33,000 total flight cycles as of the
effective date of this AD: Do the inspection within 800 flight
cycles after the effective date of this AD, but not to exceed 33,500
total flight cycles.
(5) For airplanes that have accumulated 33,000 total flight
cycles or more, but less than 37,000 total flight cycles as of the
effective date of this AD: Do the inspection within 500 flight
cycles after the effective of this AD, but not to exceed 37,300
total flight cycles.
(6) For airplanes that have accumulated 37,000 total flight
cycles or more as of the effective date of this AD: Do the
inspection within 300 flight cycles after the effective date of this
AD.
(h) Inspection Definition
For the purposes of this AD, a detailed inspection is an
intensive examination of a specific item, installation, or assembly
to detect damage, failure, or irregularity. Available lighting is
normally supplemented with a direct source of good lighting at an
intensity deemed appropriate. Inspection aids such as mirror,
magnifying lenses, etc., may be necessary. Surface cleaning and
elaborate procedures may be required.
(i) Repetitive Inspections
For any tube on which no cracking and no damage is found during
any inspection required by paragraph (g) of this AD: At the
applicable time specified in paragraph (i)(1) or (i)(2) of this AD,
repeat the detailed or eddy current inspection for cracking of the
pilot-side rudder pedal tubes, specified in paragraph (g) of this
AD, until the terminating action specified in paragraph (k) of this
AD has been accomplished.
(1) If the most recent inspection was a detailed inspection:
Repeat the inspection within 600 flight cycles thereafter.
(2) If the most recent inspection was an eddy current
inspection: Repeat the inspection within 1,000 flight cycles
thereafter.
(j) Corrective Actions
(1) If any cracking is found around the aft tapered holes during
any inspection required by paragraph (g) or (i) of this AD, before
further flight, replace the affected rudder bar assemblies, in
accordance with the Accomplishment Instructions of Bombardier
