SUPPLEMENTARY INFORMATION:
RIN 2120–AA64
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all Bombardier, Inc. Model CL–
600–2B19 (Regional Jet Series 100 &
440) airplanes. The NPRM published in
the Federal Register on August 13, 2013
(78 FR 49227). The NPRM was
prompted by reports of burr marks on
the primary wheels, and cracked rings
on the primary wheel shaft, on certain
HSTAs. The NPRM proposed to require
replacing certain HSTAs. We are issuing
this AD to prevent burr marks on the
primary wheels, and cracked rings on
the primary wheel shaft, on certain
HSTAs, which may lead to a disconnect
of the pitch trim surface and subsequent
loss of pitch control, resulting in loss of
control of the airplane.
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2012–18,
dated May 29, 2012 (referred to after
this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for the specified products. The MCAI

SUMMARY: We are adopting a new
airworthiness directive (AD) for all
Bombardier, Inc. Model CL–600–2B19
(Regional Jet Series 100 & 440)
airplanes. This AD was prompted by
reports of burr marks on the primary
wheels, and cracked rings on the
primary wheel shaft, on certain
horizontal stabilizer trim actuators
(HSTAs). This AD requires replacing
certain HSTAs. We are issuing this AD
to prevent burr marks on the primary
wheels, and cracked rings on the
primary wheel shaft, on certain HSTAs,
which may lead to a disconnect of the
pitch trim surface and subsequent loss
of pitch control, resulting in loss of
control of the airplane.
DATES: This AD becomes effective April
7, 2014.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of April 7, 2014.

It was discovered that a number of primary
wheels on the HSTA P/N [part number]
601R92305–5 (or vendor P/N 8396–4) had
burr marks. Investigation revealed that the
burr marks were a result of incorrectly using
the manufacturing process. In addition, some
rings that were fitted on the primary wheel
shaft were found cracked. If not corrected,
this condition may lead to a disconnect of the
pitch trim surface and subsequent loss of
pitch control.
This [Canadian] AD mandates the removal
of the affected units that have the above
described manufacturing defect.
Corrective actions include replacement
of certain HSTAs. You may examine the
MCAI in the AD docket on the Internet
at https://www.regulations.gov/

Comments
We gave the public the opportunity to
participate in developing this AD. We
have considered the comment received.
The following presents the comment
received on the proposal (78 FR 49227,
August 13, 2013) and the FAA’s
response to the comment.

Request To Revise the Applicability
Air Wisconsin Airlines requested that
we limit the applicability of the NPRM
(78 FR 49227, August 13, 2013) to
Model CL–6–2B19 (Regional Jet Series
100 & 440) airplanes ‘‘equipped with
HSTAs having part number (P/N)
601R92305–5 or vendor P/N 8396–4,
with serial numbers (S/N)s as identified
in paragraph (g) of this AD.’’
We disagree with the commenter’s
request. The intent of the applicability
in the NPRM (78 FR 49227, August 13,
2013) and this final rule was to capture
all possible airplanes that could have an
affected HSTA, or on which an affected
HSTA could be installed in the future.
This issue was coordinated with TCCA.
The parts installation limitation,
which applies to all Model CL–600–
2B19 (Regional Jet Series 100 & 440)
airplanes, is retained in this final rule.
This provision matches the intent of
Canadian AD CF–2012–18, dated May
29, 2012. We have made no changes to
this final rule in this regard.
Also, we have specified serial
numbers 7003 and subsequent (which
includes all serial numbers) in
paragraph (c) in this final rule, which
corresponds with the Applicability of
Canadian AD CF–2012–18, dated May
29, 2012.
Conclusion
We reviewed the relevant data,
considered the comment received, and
determined that air safety and the
public interest require adopting this AD
as proposed except for minor editorial
changes. We have determined that these
minor changes:
• Are consistent with the intent that
was proposed in the NPRM (78 FR
49227, August 13, 2013) for correcting
the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (78 FR 49227,
August 13, 2013).
Costs of Compliance
We estimate that this AD affects 575
airplanes of U.S. registry.
We also estimate that it will take
about 19 work-hours per product to
comply with the basic requirements of
this AD. The average labor rate is $85
per work-hour. Required parts will cost
about $0 per product. Based on these
figures, we estimate the cost of this AD
on U.S. operators to be $928,625, or
$1,615 per product.
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
E:\FR\FM\03MRR1.SGM
03MRR1
11692
Federal Register / Vol. 79, No. 41 / Monday, March 3, 2014 / Rules and Regulations
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 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 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.

SUMMARY: We are superseding
Airworthiness Directive (AD) 2002–23–
19 for all Dassault Aviation Model
FALCON 2000 series airplanes. AD
2002–23–19 required repetitive
operational tests, repetitive
measurements, and repetitive
replacement of certain jackscrews. This
new AD requires revising the
maintenance program to incorporate
new or revised maintenance
requirements and airworthiness
limitations. This AD was prompted by
the manufacturer revising the airplane
maintenance manual (AMM)
maintenance requirements and
airworthiness limitations. We are
issuing this AD to prevent reduced
controllability of the airplane.

We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2002–23–19,
Amendment 39–12963 (67 FR 71452,
December 2, 2002). AD 2002–23–19
applied to all Dassault Aviation Model
FALCON 2000 series airplanes. The
NPRM published in the Federal
Register on July 12, 2013 (78 FR 41882).
The NPRM proposed to revise the
maintenance program to incorporate
new or revised maintenance
requirements and airworthiness
limitations.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2012–0156,
dated August 23, 2012 (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:
The airworthiness limitations and
maintenance requirements for the Falcon
2000 type design are included in Dassault
Aviation Falcon 2000 (F2000) Aircraft
Maintenance Manual (AMM) chapter 5–40
and are approved by the European Aviation
Safety Agency (EASA). EASA issued AD
2008–0221 [https://ad.easa.europa.eu/blob/
easa_ad_2008_0221_Corrected.pdf/AD_
2008–0221_1] to require accomplishment of
the maintenance tasks, and implementation
of the airworthiness limitations, as specified
in Dassault Aviation F2000 AMM chapter 5–
40 at revision 12.
Since that [EASA] AD was issued, Dassault
Aviation have issued F2000 AMM chapter 5–
40 at revision 17, which introduces new or
more restrictive maintenance requirements
and/or airworthiness limitations.

Dassault Aviation AMM chapter 5–40
revision 17 contains among other changes the
following requirements:
—Inspection and test of horizontal
stabilizer jackscrew;
—Operational test of voltage monitoring
circuits;
—Upgrade of screwjack of flap actuators
from the older to the latest -3 version;
—Revised Time Between Overhaul for
screwjack of flap actuators -3 version;
—Revised interval for checking the screw/
nut play on screwjack of flap actuators -3
version;
—Removal of service life limit for
screwjack of flap actuators;
—Test of flap asymmetry protection
system. Compliance with the flap asymmetry
´ ´
test is required by DGAC [Direction Generale

008(B)R1 [which can be found in the AD
docket at https://www.regulations.gov/
#!documentDetail;D=FAA-2013-0466-0002.
F2000 AMM chapter 5–40 at revision 17
introduces extended inspection interval;
—Inspection procedures of fuselage and
wings;
—Check of overpressure tightness on
pressurization control regulating valves.
Compliance with this check is required by
EASA AD 2008–0072 [https://
ad.easa.europa.eu/blob/easa_ad_2008_
0072.pdf/AD_2008-0072_1]. F2000 AMM
chapter 5–40 at revision 17 introduces
extended inspection interval.
The maintenance tasks and airworthiness
limitations, as specified in the F2000 AMM
chapter 5–40, have been identified as
mandatory actions for continued
airworthiness of the F2000 type design.
Failure to comply with AMM chapter 5–40
at revision 17 might constitute an unsafe
condition.
*
*
*
*

The required action is revising the
maintenance program to incorporate all
airworthiness limitations and
maintenance tasks specified in Chapter
5–40, Airworthiness Limitations,
Revision 18, dated July 2012, of Chapter
5, Maintenance Planning Document, of
the Dassualt Falcon 2000 Maintenance
Manual. You may examine the MCAI in

Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM (78
FR 41882, July 12, 2013) or on the
determination of the cost to the public.
Explanation of Changes to This Final
Rule
After the NPRM (78 FR 41882, July
12, 2013) was published, we determined
that it was not necessary to retain the
requirements of AD 2010–26–05,
Amendment 39–16544 (75 FR 79952,
December 21, 2010), in this final rule.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to all Bombardier, Inc. Model
CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM
published in the Federal Register on August 13, 2013 (78 FR 49227). The
NPRM was prompted by reports of burr marks on the primary wheels, and
cracked rings on the primary wheel shaft, on certain HSTAs. The NPRM
proposed to require replacing certain HSTAs. We are issuing this AD to
prevent burr marks on the primary wheels, and cracked rings on the
primary wheel shaft, on certain HSTAs, which may lead to a disconnect
of the pitch trim surface and subsequent loss of pitch control,
resulting in loss of control of the airplane.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2012-18, dated May 29, 2012 (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:
It was discovered that a number of primary wheels on the HSTA P/
N [part number] 601R92305-5 (or vendor P/N 8396-4) had burr marks.
Investigation revealed that the burr marks were a result of
incorrectly using the manufacturing process. In addition, some rings
that were fitted on the primary wheel shaft were found cracked. If
not corrected, this condition may lead to a disconnect of the pitch
trim surface and subsequent loss of pitch control.
This [Canadian] AD mandates the removal of the affected units
that have the above described manufacturing defect.
Corrective actions include replacement of certain HSTAs. You may
examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2013-0687-0003.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comment received. The following
presents the comment received on the proposal (78 FR 49227, August 13,
2013) and the FAA's response to the comment.
Request To Revise the Applicability
Air Wisconsin Airlines requested that we limit the applicability of
the NPRM (78 FR 49227, August 13, 2013) to Model CL-6-2B19 (Regional
Jet Series 100 & 440) airplanes ``equipped with HSTAs having part
number (P/N) 601R92305-5 or vendor P/N 8396-4, with serial numbers (S/
N)s as identified in paragraph (g) of this AD.''
We disagree with the commenter's request. The intent of the
applicability in the NPRM (78 FR 49227, August 13, 2013) and this final
rule was to capture all possible airplanes that could have an affected
HSTA, or on which an affected HSTA could be installed in the future.
This issue was coordinated with TCCA.
The parts installation limitation, which applies to all Model CL-
600-2B19 (Regional Jet Series 100 & 440) airplanes, is retained in this
final rule. This provision matches the intent of Canadian AD CF-2012-
18, dated May 29, 2012. We have made no changes to this final rule in
this regard.
Also, we have specified serial numbers 7003 and subsequent (which
includes all serial numbers) in paragraph (c) in this final rule, which
corresponds with the Applicability of Canadian AD CF-2012-18, dated May
29, 2012.
Conclusion
We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting
this AD as proposed except for minor editorial changes. We have
determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (78 FR 49227, August 13, 2013) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 49227, August 13, 2013).
Costs of Compliance
We estimate that this AD affects 575 airplanes of U.S. registry.
We also estimate that it will take about 19 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $0 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $928,625, or $1,615 per product.
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
[[Page 11692]]
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 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 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.
