Discussion
The FAA issued AD 2015–05–03,
Amendment 39–18113 (80 FR 13758,
March 17, 2015) (‘‘AD 2015–05–03’’), for
certain MHI RJ Aviation ULC Model
CL–600–2B19 (Regional Jet Series 100 &
440) airplanes. AD 2015–05–03 requires
revising the maintenance or inspection
program, as applicable, to incorporate
new or revised maintenance
requirements and airworthiness
limitations, and incorporating structural
repairs and modifications to preclude
VerDate Sep<11>2014

Jkt 253001
WFD. AD 2015–05–03 resulted from
reports of cracking on the skin panels
and skin splice joints and angles at
certain stringers at various locations
between certain fuselage stations. The
FAA issued AD 2015–05–03 to address
WFD, which could adversely affect the
structural integrity of the airplane.
Actions Since AD 2015–05–03 Was
Issued
Since the FAA issued AD 2015–05–
03, the FAA has determined that new or
more restrictive airworthiness
limitations are necessary, as well as the
corresponding structural repairs and
modifications to preclude WFD.
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2014–07R1, dated July 13, 2020
(referred to after this as the Mandatory
Continuing Airworthiness Information,
or ‘‘the MCAI’’), to correct an unsafe
condition for certain MHI RJ Aviation
ULC Model CL–600–2B19 (Regional Jet
Series 100 & 440) airplanes. 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–2020–
0913.
This proposed AD was prompted by
a determination that new or more
restrictive airworthiness limitations are
necessary, as well as the corresponding
structural repairs and modifications to
preclude WFD. The manufacturer
discovered inconsistencies between the
Engineering Structure Reports and
Maintenance Tasks for the inspection of
fuselage skin longitudinal splices along
a certain stringer. The FAA is proposing
this AD to address WFD, which could
adversely affect the structural integrity
of the airplane. See the MCAI for
additional background information.
Related Service Information Under 1
CFR Part 51
MHI RJ Aviation has issued
Bombardier Temporary Revision 2B–
2280, dated June 12, 2020. This service
information, among other actions,
describes airworthiness limitation
(AWL) task 53–41–207, which specifies
airworthiness limitations and
inspections for fuselage and
longitudinal skin splices at stringer
(STR) 6 and 20.
This proposed AD would also require
the following service information,
which the Director of the Federal
Register approved for incorporation by
reference as of April 21, 2015 (80 FR
13758, March 17, 2015).

This service information is reasonably
available because the interested parties
have access to it through their normal
course of business or by the means
identified in the ADDRESSES section.
FAA’s Determination
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to the
FAA’s bilateral agreement with the State
of Design Authority, the FAA has been
notified of the unsafe condition
described in the MCAI and service
information referenced above. The FAA
is proposing this AD because the FAA
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design.
Proposed Requirements of This NPRM
This proposed AD would retain
certain requirements of AD 2015–05–03.
This proposed AD would require
revising the existing maintenance or
inspection program, as applicable, to
incorporate new or more restrictive
airworthiness limitations and would
require incorporating structural repairs
and modifications to preclude WFD.
This proposed AD would require
revisions to certain operator
maintenance documents to include new
actions (e.g., inspections). Compliance
with these actions is required by 14 CFR
91.403(c). For airplanes that have been
previously modified, altered, or repaired
in the areas addressed by this proposed
AD, the operator may not be able to
accomplish the actions 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 (n)(1) of this proposed AD.
Costs of Compliance
The FAA estimates that this proposed
AD affects 431 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this proposed AD:
The FAA estimates the total cost per
operator for the retained actions from
E:\FR\FM\14OCP1.SGM
14OCP1
Federal Register / Vol. 85, No. 199 / Wednesday, October 14, 2020 / Proposed Rules
AD 2015–05–03 to be $7,650 (90 workhours × $85 per work-hour).
The FAA has determined that revising
the maintenance or inspection program
takes an average of 90 work-hours per
operator, although the agency
recognizes that this number may vary
from operator to operator. In the past,
the agency has estimated that this action
takes 1 work-hour per airplane. Since
operators incorporate maintenance or
inspection program changes for their
affected fleet(s), the FAA has
determined that a per-operator estimate
is more accurate than a per-airplane
estimate. Therefore, the agency
estimates the average total cost per
operator to be $7,650 (90 work-hours ×
$85 per work-hour).
The FAA has received no definitive
data that would enable us to provide
cost estimates for the repairs and
modifications specified in this proposed
AD.
jbell on DSKJLSW7X2PROD with PRO_RULES
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.
The FAA is 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
The FAA 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) Will not affect intrastate aviation
in Alaska, and
(3) Will not have a significant
economic impact, positive or negative,

Discussion
The FAA has received reports of the
airplane power lever linkage detaching
from the TPE331 engine PPC shaft. In
flight operations, detachment may result
in fuel flow to the engine remaining
constant regardless of the power lever
movement by the pilot. The orientation
of the engine on certain M7 Aerospace
LLC airplanes increases the
vulnerability of detachment. The PPC
lever is an airplane part and its
detachment from the TPE331 has been
the subject of previous ADs on other
airplane type designs. This condition, if
not addressed, could result in
uncommanded change to the engine
power settings with consequent loss of
control.

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2015-05-03, which applies to certain MHI RJ Aviation ULC Model CL-600-
2B19 (Regional Jet Series 100 & 440) airplanes. AD 2015-05-03 requires
revising the maintenance or inspection program, as applicable, to
incorporate new or revised maintenance requirements and airworthiness
limitations, and incorporating structural repairs and modifications to
preclude widespread fatigue damage (WFD). Since the FAA issued AD 2015-
05-03, the FAA has determined that new or more restrictive
airworthiness limitations are necessary, as well as the corresponding
structural repairs and modifications to preclude WFD. This proposed AD
would require revising the existing maintenance or inspection program,
as applicable, to incorporate new or more restrictive airworthiness
limitations and would require incorporating structural repairs and
modifications to preclude WFD. The FAA is proposing this AD to address
the unsafe condition on these products.

Discussion
The FAA issued AD 2015-05-03, Amendment 39-18113 (80 FR 13758,
March 17, 2015) (``AD 2015-05-03''), for certain MHI RJ Aviation ULC
Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2015-
05-03 requires revising the maintenance or inspection program, as
applicable, to incorporate new or revised maintenance requirements and
airworthiness limitations, and incorporating structural repairs and
modifications to preclude WFD. AD 2015-05-03 resulted from reports of
cracking on the skin panels and skin splice joints and angles at
certain stringers at various locations between certain fuselage
stations. The FAA issued AD 2015-05-03 to address WFD, which could
adversely affect the structural integrity of the airplane.
Actions Since AD 2015-05-03 Was Issued
Since the FAA issued AD 2015-05-03, the FAA has determined that new
or more restrictive airworthiness limitations are necessary, as well as
the corresponding structural repairs and modifications to preclude WFD.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2014-07R1, dated July
13, 2020 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional
Jet Series 100 & 440) airplanes. 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-2020-0913.
This proposed AD was prompted by a determination that new or more
restrictive airworthiness limitations are necessary, as well as the
corresponding structural repairs and modifications to preclude WFD. The
manufacturer discovered inconsistencies between the Engineering
Structure Reports and Maintenance Tasks for the inspection of fuselage
skin longitudinal splices along a certain stringer. The FAA is
proposing this AD to address WFD, which could adversely affect the
structural integrity of the airplane. See the MCAI for additional
background information.
Related Service Information Under 1 CFR Part 51
MHI RJ Aviation has issued Bombardier Temporary Revision 2B-2280,
dated June 12, 2020. This service information, among other actions,
describes airworthiness limitation (AWL) task 53-41-207, which
specifies airworthiness limitations and inspections for fuselage and
longitudinal skin splices at stringer (STR) 6 and 20.
This proposed AD would also require the following service
information, which the Director of the Federal Register approved for
incorporation by reference as of April 21, 2015 (80 FR 13758, March 17,
2015).
AWL Task 53-41-110, Longitudinal Str. 6 splice butt strap
at Str. 6, FS409.0 to FS617.0, of Appendix B, Airworthiness
Limitations, of Part 2, Airworthiness Requirements, Revision 9, dated
June 10, 2013, of the Bombardier CL-600-2B19 Maintenance Requirements
Manual, CSP A-053.
AWL Task 53-41-204, Frame splice angles at STR 6 and 20,
of Appendix B, Airworthiness Limitations, of Part 2, Airworthiness
Requirements, Revision 9, dated June 10, 2013, of the Bombardier CL-
600-2B19 Maintenance Requirements Manual, CSP A-053.
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.
FAA's Determination
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to the FAA's bilateral agreement with the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
and service information referenced above. The FAA is proposing this AD
because the FAA evaluated all the relevant information and determined
the unsafe condition described previously is likely to exist or develop
on other products of the same type design.
Proposed Requirements of This NPRM
This proposed AD would retain certain requirements of AD 2015-05-
03. This proposed AD would require revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive airworthiness limitations and would require incorporating
structural repairs and modifications to preclude WFD.
This proposed AD would require revisions to certain operator
maintenance documents to include new actions (e.g., inspections).
Compliance with these actions is required by 14 CFR 91.403(c). For
airplanes that have been previously modified, altered, or repaired in
the areas addressed by this proposed AD, the operator may not be able
to accomplish the actions 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
(n)(1) of this proposed AD.
Costs of Compliance
The FAA estimates that this proposed AD affects 431 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
The FAA estimates the total cost per operator for the retained
actions from
[[Page 64989]]
AD 2015-05-03 to be $7,650 (90 work-hours x $85 per work-hour).
The FAA has determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although the
agency recognizes that this number may vary from operator to operator.
In the past, the agency has estimated that this action takes 1 work-
hour per airplane. Since operators incorporate maintenance or
inspection program changes for their affected fleet(s), the FAA has
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, the agency estimates the average total
cost per operator to be $7,650 (90 work-hours x $85 per work-hour).
The FAA has received no definitive data that would enable us to
provide cost estimates for the repairs and modifications specified in
this proposed 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.
The FAA is 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
The FAA 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) Will not affect intrastate aviation in Alaska, 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.
