Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2019–20R1, dated May 31, 2019
(referred to after this as the Mandatory
Continuing Airworthiness Information,
or ‘‘the MCAI’’), to correct an unsafe
condition for all Bombardier, Inc.,
Model CL–600–2C10 (Regional Jet
Series 700, 701 & 702) airplanes; Model
CL–600–2D15 (Regional Jet Series 705)
airplanes; Model CL–600–2D24
VerDate Sep<11>2014

Jkt 250001
(Regional Jet Series 900) airplanes; and
Model CL–600–2E25 (Regional Jet Series
1000) airplanes.
This proposed AD was prompted by
a report of incorrectly installed flight
compartment door edge protection
plates on both sides of the upper
decompression panel (the flight
compartment is also known as the flight
deck). The FAA is proposing this AD to
address incorrect installation of the
flight compartment door edge protection
plates on both sides of the flight
compartment door upper
decompression panel. This condition, if
not corrected, could result in the
inability of the flight compartment door
upper decompression panel to open
during a rapid decompression event.
This inability to relieve the pressure in
the flight compartment may
compromise the structural integrity of
the bulkhead between the flight
compartment and the passenger cabin.
See the MCAI for additional background
information.
Related Service Information Under 1
CFR Part 51
Bombardier, Inc., has issued Task
251700–202, ‘‘Functional Check of the
Flight Compartment Door
Decompression Latches,’’ of Section 1–
25 of Section 125, of the Maintenance
Review Board Report, Revision 18,
dated July 25, 2018, in Part 1 of the
Bombardier CRJ700/900/1000
Maintenance Requirements Manual,
CSP–B–053. This service information
describes a functional check of the flight
compartment door decompression
latches. 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 require
revising the existing maintenance or
PO 00000
Frm 00009
Fmt 4702
Sfmt 4702
inspection program, as applicable, to
incorporate a new functional check.
Costs of Compliance
The FAA estimates that this proposed
AD affects 522 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this proposed AD:
The FAA has determined that revising
the existing maintenance or inspection
program takes an average of 90 workhours per operator, although the FAA
recognizes that this number may vary
from operator to operator. In the past,
the FAA 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 FAA estimates
the total cost per operator to be $7,650
(90 work-hours × $85 per work-hour).
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.
This proposed 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 and associated
appliances to the Director of the System
Oversight Division.
Regulatory Findings
The FAA determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would not
E:\FR\FM\09OCP1.SGM
09OCP1
Federal Register / Vol. 84, No. 196 / Wednesday, October 9, 2019 / Proposed Rules
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.

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2019-20R1, dated May
31, 2019 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for all Bombardier, Inc., Model CL-600-2C10 (Regional Jet
Series 700, 701 & 702) airplanes; Model CL-600-2D15 (Regional Jet
Series 705) airplanes; Model CL-600-2D24 (Regional Jet Series 900)
airplanes; and Model CL-600-2E25 (Regional Jet Series 1000) airplanes.
This proposed AD was prompted by a report of incorrectly installed
flight compartment door edge protection plates on both sides of the
upper decompression panel (the flight compartment is also known as the
flight deck). The FAA is proposing this AD to address incorrect
installation of the flight compartment door edge protection plates on
both sides of the flight compartment door upper decompression panel.
This condition, if not corrected, could result in the inability of the
flight compartment door upper decompression panel to open during a
rapid decompression event. This inability to relieve the pressure in
the flight compartment may compromise the structural integrity of the
bulkhead between the flight compartment and the passenger cabin. See
the MCAI for additional background information.
Related Service Information Under 1 CFR Part 51
Bombardier, Inc., has issued Task 251700-202, ``Functional Check of
the Flight Compartment Door Decompression Latches,'' of Section 1-25 of
Section 125, of the Maintenance Review Board Report, Revision 18, dated
July 25, 2018, in Part 1 of the Bombardier CRJ700/900/1000 Maintenance
Requirements Manual, CSP-B-053. This service information describes a
functional check of the flight compartment door decompression latches.
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 require revising the existing maintenance or
inspection program, as applicable, to incorporate a new functional
check.
Costs of Compliance
The FAA estimates that this proposed AD affects 522 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 work-hours per operator,
although the FAA recognizes that this number may vary from operator to
operator. In the past, the FAA 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 FAA estimates the total cost per
operator to be $7,650 (90 work-hours x $85 per work-hour).
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.
This proposed 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 and associated appliances to the
Director of the System Oversight Division.
Regulatory Findings
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
[[Page 54053]]
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, 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
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 airworthiness
directive (AD):
Bombardier, Inc.: Docket No. FAA-2019-0714; Product Identifier 2019-
NM-103-AD.
