of the RTL return springs; and an
inspection of the lugs of the RTL limiter
arm assembly for cracks, and
modification or replacement, as
applicable; and applicable corrective
actions. This AD also adds airplanes to
the applicability. This AD was
prompted by reports that when
installing the RTL return springs, the
RTL limiter arm assembly lug(s) can
become deformed. We are issuing this
AD to address the unsafe condition on
these products.
DATES: This AD is effective July 10,
2018.
The Director of the Federal Register
approved the incorporation by reference

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2014–02–01,
Amendment 39–17729 (79 FR 7382,
February 7, 2014) (‘‘AD 2014–02–01’’).
AD 2014–02–01 applied to certain
Bombardier, Inc., Model CL–600–2C10
(Regional Jet Series 700, 701, & 702),
Model CL–600–2D15 (Regional Jet
Series 705), and Model CL–600–2D24
(Regional Jet Series 900) airplanes. The
NPRM published in the Federal
Register on January 16, 2018 (83 FR
2090). The NPRM was prompted by
reports that when installing RTL return
spring part number BA–670–93468–1,
the RTL limiter arm assembly lug(s) can
become deformed when the RTL return
spring attachment bolt is torqued; and
the determination that additional
airplanes are affected by the unsafe
condition. The NPRM proposed to
require an inspection of the RTL return
springs for signs of chafing; an
inspection of the casing of the primary
actuator for signs of chafing or missing
paint; replacement of the RTL return
springs; and an inspection of the lugs of
the RTL limiter arm assembly for cracks,
and modification or replacement, as
applicable; and applicable corrective

Federal Register / Vol. 83, No. 108 / Tuesday, June 5, 2018 / Rules and Regulations
actions. The NPRM also proposed to
add airplanes to the applicability. We
are issuing this AD to prevent deformed
RTL limiter arm assembly lug(s), which
can lead to failure of the RTL limiter
arm assembly lug(s). In combination
with failure of the RTL, failure of the
RTL limiter arm assembly lug(s) could
result in reduced controllability of the
airplane.
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2017–19, dated June 6, 2017
(referred to after this as the Mandatory
Continuing Airworthiness Information,
or ‘‘the MCAI’’), to correct an unsafe
condition for certain Bombardier, Inc.,
Model CL–600–2C10 (Regional Jet
Series 700, 701, & 702), Model CL–600–
2D15 (Regional Jet Series 705), and
Model CL–600–2D24 (Regional Jet
Series 900) airplanes. The MCAI states:
Transport Canada AD CF–2010–18R1
[which corresponds to FAA AD 2014–02–01]
mandated a repetitive inspection and
introduced a new rudder travel limiter (RTL)
return spring, part number (P/N) BA670–
93468–1, to correct the potential dormant
RTL spring failure. This [Canadian] AD is
issued to supersede the repetitive inspection
and the replacement of the RTL spring due
to discoveries made after the issuance of
[Canadian] AD CF–2010–18R1.
When installing the RTL return spring P/
N BA670–93468–1 as mandated by
[Canadian] AD CF–2010–18R1, it was found
that it is possible for the RTL limiter arm
assembly lug to be deformed. The lugs
become bent when the RTL return spring
attachment bolt is torqued. This condition, if
not corrected, can lead to failure of the
limiter arm assembly lug. In combination
with failure of the RTL, failure of the limiter
arm assembly lug could affect the
controllability of the aeroplane.
This [Canadian] AD mandates the
inspection for cracked RTL limiter arm lugs
and modification of the RTL limiter arm to
prevent the RTL limiter arm lugs from
bending during RTL assembly.
Required actions include: A detailed
visual inspection of the RTL return
springs for signs of chafing; a detailed
visual inspection of the casing of the
primary actuator for signs of chafing or
missing paint; replacement of the RTL
return springs; an eddy current
inspection of the lugs of the RTL limiter
arm assembly for cracks, and
modification or replacement of the RTL
limiter arm assembly, as applicable; and
applicable corrective actions. Corrective
actions include: replacement of the RTL
return springs, repair of the primer and
topcoat of the primary actuator, and
replacement of the primary actuator.
You may examine the MCAI in the AD
docket on the internet at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2017–
1246.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comment received. The
Air Line Pilots Association,
International supported the NPRM.
Conclusion
We reviewed the available data,
including the comment received, and
25883
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 for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.
Related Service Information Under 1
CFR Part 51

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:

Boeing winglets installed. This AD
requires high frequency eddy current
(HFEC) inspections for cracking of the
lower outboard wing skin, and repair or
modification if necessary. This AD also
requires one of three follow-on actions:
Repeating the HFEC inspections,
modifying certain internal stringers and
oversizing and plugging the existing
fastener holes of the lower wing, or
modifying the external doubler/tripler
and doing repetitive post-modification
inspections. We are issuing this AD to
address the unsafe condition on these
products.

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 certain The Boeing Company
Model 767–300 and –300F series
airplanes. The NPRM published in the
Federal Register on June 5, 2015 (80 FR
32066). The NPRM was prompted by
reports of fatigue cracking on airplanes
with Aviation Partners Boeing winglets
installed. The NPRM proposed to
require a HFEC inspection for cracking
of the lower outboard wing skin, and
repair or modification if necessary. The
NPRM also proposed to require one of
three follow-on actions: Repeating the
HFEC inspections, modifying certain
internal stringers and oversizing and
plugging the existing fastener holes of
the lower wing, or modifying the
external doubler/tripler and doing
repetitive post-modification inspections.
We issued an SNPRM to amend 14
CFR part 39 by adding an AD that
would apply to certain The Boeing
Company Model 767–300 and –300F
series airplanes. The SNPRM published
in the Federal Register on November 27,
2017 (82 FR 55958). The SNPRM
proposed adding new HFEC inspections
for cracking of an expanded area of the
lower outboard wing skin for certain
airplanes.
We are issuing this AD to address
fatigue cracking in the lower outboard
wing skin, which could result in failure
and subsequent separation of the wing

Request To Correct Compliance Time
Aviation Partners Boeing (APB) and
United Airlines (UAL) asked that we
correct the compliance time in
paragraphs (h)(2)(ii) and (h)(3)(ii) of the
proposed AD (in the SNPRM). The
commenters stated that those
paragraphs would require the initial
post-repair HFEC inspection of the
lower wing skin at stringer L–6.5 at the
applicable time specified in paragraph
1.E., ‘‘Compliance,’’ of Aviation Partners
Boeing Service Bulletin AP767–57–014,
Revision 1, dated April 12, 2017. The
commenters added that the compliance
time for the Part 3 HFEC inspection
specified in paragraph 1.E. does not
begin after doing the Part 2 repair, but
instead begins after the initial issue of
the service bulletin (after the effective
date of the AD). UAL stated that, as
written, this would require doing postrepair inspections on airplanes above
the total flight-hour and flight-cycle
threshold within 18 months after the
effective date of the AD, regardless of if
or when the repair was actually done.
APB confirmed that the calendar-based
compliance time in the referenced
service information, for airplanes in
Group 1, Configurations 2 and 3, and
Groups 2 and 3, should be the same as
for airplanes in Group 1, Configuration
1, on which the Part 2 repair has been
done. The commenters asked that the
compliance time for the Part 3 HFEC
inspection be corrected to the following:
‘‘Within 6,000 flight cycles after doing
the Part 2 repair, or within 18,000 flight
hours since doing the Part 2 repair,
whichever occurs first.’’
We agree with the commenters’
request for the reasons provided. We
have added paragraph (j)(3) of this AD
to include this compliance-time
exception.
Request To Remove a Certain
Terminating Action
Boeing asked that we remove the
terminating action sentence at the end
of paragraph (g)(2) of the proposed AD
(in the SNPRM). Paragraph (g)(2) of the
proposed AD (in the SNPRM) applies to
Group 3 airplanes with external
doublers, and if a crack is found it
requires a repair using a method

SUMMARY: We are superseding Airworthiness Directive (AD) 2014-02-01,
which applied to certain Bombardier, Inc., Model CL-600-2C10 (Regional
Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series
705), and Model CL-600-2D24 (Regional Jet Series 900) airplanes. AD
2014-02-01 required repetitive inspections of the rudder travel limiter
(RTL) return springs and primary actuator, and corrective actions if
necessary; and replacement of certain RTL return springs. This AD
requires an inspection of the RTL return springs for signs of chafing;
an inspection of the casing of the primary actuator for signs of
chafing or missing paint; replacement of the RTL return springs; and an
inspection of the lugs of the RTL limiter arm assembly for cracks, and
modification or replacement, as applicable; and applicable corrective
actions. This AD also adds airplanes to the applicability. This AD was
prompted by reports that when installing the RTL return springs, the
RTL limiter arm assembly lug(s) can become deformed. We are issuing
this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2014-02-01, Amendment 39-17729 (79 FR 7382,
February 7, 2014) (``AD 2014-02-01''). AD 2014-02-01 applied to certain
Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, &
702), Model CL-600-2D15 (Regional Jet Series 705), and Model CL-600-
2D24 (Regional Jet Series 900) airplanes. The NPRM published in the
Federal Register on January 16, 2018 (83 FR 2090). The NPRM was
prompted by reports that when installing RTL return spring part number
BA-670-93468-1, the RTL limiter arm assembly lug(s) can become deformed
when the RTL return spring attachment bolt is torqued; and the
determination that additional airplanes are affected by the unsafe
condition. The NPRM proposed to require an inspection of the RTL return
springs for signs of chafing; an inspection of the casing of the
primary actuator for signs of chafing or missing paint; replacement of
the RTL return springs; and an inspection of the lugs of the RTL
limiter arm assembly for cracks, and modification or replacement, as
applicable; and applicable corrective
[[Page 25883]]
actions. The NPRM also proposed to add airplanes to the applicability.
We are issuing this AD to prevent deformed RTL limiter arm assembly
lug(s), which can lead to failure of the RTL limiter arm assembly
lug(s). In combination with failure of the RTL, failure of the RTL
limiter arm assembly lug(s) could result in reduced controllability of
the airplane.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2017-19, dated June 6,
2017 (referred to after this as the Mandatory Continuing Airworthiness
Information, or ``the MCAI''), to correct an unsafe condition for
certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700,
701, & 702), Model CL-600-2D15 (Regional Jet Series 705), and Model CL-
600-2D24 (Regional Jet Series 900) airplanes. The MCAI states:
Transport Canada AD CF-2010-18R1 [which corresponds to FAA AD
2014-02-01] mandated a repetitive inspection and introduced a new
rudder travel limiter (RTL) return spring, part number (P/N) BA670-
93468-1, to correct the potential dormant RTL spring failure. This
[Canadian] AD is issued to supersede the repetitive inspection and
the replacement of the RTL spring due to discoveries made after the
issuance of [Canadian] AD CF-2010-18R1.
When installing the RTL return spring P/N BA670-93468-1 as
mandated by [Canadian] AD CF-2010-18R1, it was found that it is
possible for the RTL limiter arm assembly lug to be deformed. The
lugs become bent when the RTL return spring attachment bolt is
torqued. This condition, if not corrected, can lead to failure of
the limiter arm assembly lug. In combination with failure of the
RTL, failure of the limiter arm assembly lug could affect the
controllability of the aeroplane.
This [Canadian] AD mandates the inspection for cracked RTL
limiter arm lugs and modification of the RTL limiter arm to prevent
the RTL limiter arm lugs from bending during RTL assembly.
Required actions include: A detailed visual inspection of the RTL
return springs for signs of chafing; a detailed visual inspection of
the casing of the primary actuator for signs of chafing or missing
paint; replacement of the RTL return springs; an eddy current
inspection of the lugs of the RTL limiter arm assembly for cracks, and
modification or replacement of the RTL limiter arm assembly, as
applicable; and applicable corrective actions. Corrective actions
include: replacement of the RTL return springs, repair of the primer
and topcoat of the primary actuator, and replacement of the primary
actuator. You may examine the MCAI in the AD docket on the internet at
https://www.regulations.gov by searching for and locating Docket No.
FAA-2017-1246.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comment received. The Air Line Pilots
Association, International supported the NPRM.
Conclusion
We reviewed the available data, including 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 for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
Bombardier has issued Bombardier Service Bulletin 670BA-27-070,
Revision B, dated March 31, 2017. This service information describes

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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes to
the Director of the System Oversight Division.
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);
[[Page 25884]]
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.
