Federal Register / Vol. 84, No. 210 / Wednesday, October 30, 2019 / Proposed Rules
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
1. The authority citation for part 39
continues to read as follows:
■
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new airworthiness
directive (AD):
■
Airbus SAS: Docket No. FAA–2019–0721;
Product Identifier 2019–NM–150–AD.
(a) Comments Due Date
The FAA must receive comments by
December 16, 2019.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Airbus SAS Model
A350–941 and –1041 airplanes, certificated
in any category, as identified in European
Union Aviation Safety Agency (EASA) AD
2019–0210, dated August 26, 2019 (‘‘EASA
AD 2019–0210’’).
(d) Subject
Air Transport Association (ATA) of
America Code 35, Oxygen.
(e) Reason
This AD was prompted by a report that
during inspection of the installation of
oxygen containers, certain fasteners of the
oxygen containers and adjacent panels in the
passenger supply channels (PSCs) were
found damaged or unlocked; which could
result in insufficient clearance between the
oxygen container and adjacent panels. The
FAA is issuing this AD to address this
condition, which could prevent the opening
of the oxygen containers and result in failure
of the oxygen masks to deploy and provide
supplemental oxygen in case of an in-flight
decompression, possibly resulting in injury
to cabin occupants.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
(g) Requirements
Except as specified in paragraph (h) of this
AD: Comply with all required actions and
compliance times specified in, and in
accordance with, EASA AD 2019–0210.
(h) Exceptions to EASA AD 2019–0210
(1) Where EASA AD 2019–0210 refers to its
effective date, this AD requires using the
effective date of this AD.
(2) The ‘‘Remarks’’ section of EASA AD
2019–0210 does not apply to this AD.

Jkt 250001
(i) No Reporting Requirement
Although the service information
referenced in EASA AD 2019–0210 specifies
to submit certain information to the
manufacturer, this AD does not include that
requirement.
(j) Other FAA AD Provisions
The following provisions also apply to this
AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, International
Section, Transport Standards Branch, FAA,
has the authority to approve AMOCs for this
AD, if requested using the procedures found
in 14 CFR 39.19. In accordance with 14 CFR
39.19, send your request to your principal
inspector or local Flight Standards District
Office, as appropriate. If sending information
directly to the International Section, send it
to the attention of the person identified in
paragraph (k)(2) of this AD. Information may
be emailed to: 9-ANM-116-AMOCREQUESTS@faa.gov. Before using any
approved AMOC, notify your appropriate
principal inspector, or lacking a principal
inspector, the manager of the local flight
standards district office/certificate holding
district office.
(2) Contacting the Manufacturer: For any
requirement in this AD to obtain instructions
from a manufacturer, the instructions must
be accomplished using a method approved
by the Manager, International Section,
Transport Standards Branch, FAA; or EASA;
or Airbus SAS’s EASA Design Organization

ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to
supersede Airworthiness Directive (AD)
2003–09–04 R1, which applies to
certain Bombardier, Inc., Model CL–
600–2B19 (Regional Jet series 100 & 440)
airplanes. AD 2003–09–04 R1 requires
revising the airworthiness limitations
for certain structural inspections; repair
if necessary; and submission of
inspection findings to the airplane
manufacturer. Since the FAA issued AD
2003–09–04 R1, the agency determined
that additional airplanes are affected,
that new or more restrictive
airworthiness limitations are necessary,
and that the compliance time must be
revised to include a phase-in time for
certain tasks. This proposed AD would
revise the applicability to include
additional airplanes; revise certain
compliance times; and require revising
the existing maintenance or inspection
program, as applicable, to incorporate
new or more restrictive airworthiness
limitations. The FAA is proposing this
AD to address the unsafe condition on
these products.
DATES: The FAA must receive comments
on this proposed AD by December 16,
2019.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Discussion
The FAA issued AD 2003–09–04 R1,
Amendment 39–13305 (68 FR 54985,
September 22, 2003) (‘‘AD 2003–09–04
R1’’), for certain Bombardier Model CL–
600–2B19 (Regional Jet series 100 & 440)
airplanes. (AD 2003–09–04 R1 revised
AD 2003–09–04, Amendment 39–13133
(68 FR 22587, April 29, 2003).) AD
2003–09–04 R1 requires revising the
airworthiness limitations section of the
Instructions for Continued
Airworthiness to incorporate new
structural inspection intervals for the
pressure floor skin of the center fuselage
at fuselage stations 460 and 513; repair
if necessary; and submission of
inspection findings to the airplane
manufacturer. AD 2003–09–04 R1
resulted from a report of fatigue cracks
on the pressure floor skin of the center
fuselage at fuselage stations 460 and
513. The FAA issued AD 2003–09–04
R1 to address fatigue cracks of the
pressure floor skin of the center fuselage
at fuselage stations 460 and 513, which
could result in failure of the pressure
floor skin and consequent rapid
decompression of the airplane during
flight.
Actions Since AD 2003–09–04 R1 Was
Issued
Since the FAA issued AD 2003–09–04
R1, the agency has determined that the
applicability must be revised to include
additional airplane serial numbers, that
new or more restrictive airworthiness
limitations are necessary, and that the
compliance time must be revised to
include a phase-in time for certain
airworthiness limitations tasks.
Transport Canada Civil Aviation
(TCCA), which is the civil aviation
authority for Canada, has issued
Canadian AD CF–2002–39R2, dated
August 15, 2019 (referred to after this as
the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Bombardier Model CL–600–
2B19 (Regional Jet series 100 & 440)
airplanes.
This proposed AD was prompted by
a report of fatigue cracks on the pressure
floor skin of the center fuselage at
fuselage stations 460 and 513. The FAA
is proposing this AD to address such
fatigue cracks, which could result in
failure of the pressure floor skin and
consequent rapid decompression of the
airplane during flight. See the MCAI for
additional background information.

Related Service Information Under 1
CFR Part 51
Bombardier has issued Bombardier
CL–600–2B19 Temporary Revision 2B–
2265, dated July 19, 2018, to Appendix
B—Airworthiness Limitations, of Part 2
of the Bombardier Maintenance
Requirements Manual; and Bombardier
CL–600–2B19 Temporary Revision 2B–
2266, dated July 19, 2018, to Appendix
B—Airworthiness Limitations, of Part 2
of the Bombardier Maintenance
Requirements Manual. These temporary
revisions describe airworthiness
limitations for inspections of the
pressure floor skin. These documents
are distinct since they describe different
airworthiness limitations.
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 agency has
been notified of the unsafe condition
described in the MCAI and service
information referenced above. The FAA
is proposing this AD because the agency
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 new or more restrictive
airworthiness limitations.
This AD requires 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 (k)(1) of this proposed AD.
The request should include a
description of changes to the required
actions that will ensure the continued
damage tolerance of the affected
structure.

58064
Federal Register / Vol. 84, No. 210 / Wednesday, October 30, 2019 / Proposed Rules
Differences Between This Proposed AD
and the MCAI or Service Information
The MCAI specifies that if there are
findings from the airworthiness
limitations section (ALS) inspection
tasks, corrective actions must be
accomplished in accordance with
Bombardier maintenance
documentation. However, this proposed
AD does not include that requirement.
Operators of U.S.-registered airplanes
are required by general airworthiness
and operational regulations to perform
maintenance using methods that are
acceptable to the FAA. The FAA
considers those methods to be adequate
to address any corrective actions
necessitated by the findings of ALS
inspections required by this proposed
AD.
Costs of Compliance
The FAA estimates that this proposed
AD would affect 37 airplanes of U.S.
registry.
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).
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.
VerDate Sep<11>2014
16:25 Oct 29, 2019
Jkt 250001
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
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.

(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain De Havilland Aircraft of Canada
Limited Model DHC–8–400 series
airplanes. This proposed AD was
prompted by reports of wear on fuel
couplings, bonding springs, and sleeves
as well as fuel tube end ferrules and fuel

component end ferrules. This proposed
AD would require repetitive inspections
of certain parts for discrepancies that
meet specified criteria, and replacement
as necessary; repetitive inspections of
certain parts for damage and wear, and
rework of parts; and electrical bonding
checks of certain couplings. This
proposed AD would also require
revising the existing maintenance or
inspection program, as applicable, to
incorporate new or more restrictive
airworthiness limitations. For certain
airplanes, this proposed AD would
allow a modification that would
terminate the repetitive inspections. The
FAA is proposing this AD to address the
unsafe condition on these products.

Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2017–04R2, dated September 25,
2018 (referred to after this as the
Mandatory Continuing Airworthiness
Information, or ‘‘the MCAI’’), to correct
an unsafe condition for certain De
Havilland Aircraft of Canada Limited
Model DHC–8–400 series airplanes.
The FAA has received reports of wear
on fuel couplings, bonding springs, and
sleeves as well as fuel tube end ferrules
and fuel component end ferrules. The
FAA is proposing this AD to address
such wear, which could reduce the
integrity of the electrical bonding paths
through the fuel line and components,
and ultimately lead to fuel tank ignition
in the event of a lightning strike. See the
MCAI for more information.
The FAA issued a related NPRM that
proposed to amend 14 CFR part 39 by
adding an AD that would apply to
certain Bombardier, Inc., Model DHC–
8–400 series airplanes. The related
NPRM published in the Federal
Register on July 6, 2018 (83 FR 31488).
The related NPRM was also prompted
by reports of wear on fuel couplings,
bonding springs, and sleeves as well as
fuel tube end ferrules and fuel
component end ferrules. Since the

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2003-09-04 R1, which applies to certain Bombardier, Inc., Model CL-600-
2B19 (Regional Jet series 100 & 440) airplanes. AD 2003-09-04 R1
requires revising the airworthiness limitations for certain structural
inspections; repair if necessary; and submission of inspection findings
to the airplane manufacturer. Since the FAA issued AD 2003-09-04 R1,
the agency determined that additional airplanes are affected, that new
or more restrictive airworthiness limitations are necessary, and that
the compliance time must be revised to include a phase-in time for
certain tasks. This proposed AD would revise the applicability to
include additional airplanes; revise certain compliance times; and
require revising the existing maintenance or inspection program, as
applicable, to incorporate new or more restrictive airworthiness
limitations. The FAA is proposing this AD to address the unsafe
condition on these products.

Discussion
The FAA issued AD 2003-09-04 R1, Amendment 39-13305 (68 FR 54985,
September 22, 2003) (``AD 2003-09-04 R1''), for certain Bombardier
Model CL-600-2B19 (Regional Jet series 100 & 440) airplanes. (AD 2003-
09-04 R1 revised AD 2003-09-04, Amendment 39-13133 (68 FR 22587, April
29, 2003).) AD 2003-09-04 R1 requires revising the airworthiness
limitations section of the Instructions for Continued Airworthiness to
incorporate new structural inspection intervals for the pressure floor
skin of the center fuselage at fuselage stations 460 and 513; repair if
necessary; and submission of inspection findings to the airplane
manufacturer. AD 2003-09-04 R1 resulted from a report of fatigue cracks
on the pressure floor skin of the center fuselage at fuselage stations
460 and 513. The FAA issued AD 2003-09-04 R1 to address fatigue cracks
of the pressure floor skin of the center fuselage at fuselage stations
460 and 513, which could result in failure of the pressure floor skin
and consequent rapid decompression of the airplane during flight.
Actions Since AD 2003-09-04 R1 Was Issued
Since the FAA issued AD 2003-09-04 R1, the agency has determined
that the applicability must be revised to include additional airplane
serial numbers, that new or more restrictive airworthiness limitations
are necessary, and that the compliance time must be revised to include
a phase-in time for certain airworthiness limitations tasks.
Transport Canada Civil Aviation (TCCA), which is the civil aviation
authority for Canada, has issued Canadian AD CF-2002-39R2, dated August
15, 2019 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain Bombardier Model CL-600-2B19 (Regional Jet series
100 & 440) airplanes.
This proposed AD was prompted by a report of fatigue cracks on the
pressure floor skin of the center fuselage at fuselage stations 460 and
513. The FAA is proposing this AD to address such fatigue cracks, which
could result in failure of the pressure floor skin and consequent rapid
decompression of the airplane during flight. See the MCAI for
additional background information.
Related Service Information Under 1 CFR Part 51
Bombardier has issued Bombardier CL-600-2B19 Temporary Revision 2B-
2265, dated July 19, 2018, to Appendix B--Airworthiness Limitations, of
Part 2 of the Bombardier Maintenance Requirements Manual; and
Bombardier CL-600-2B19 Temporary Revision 2B-2266, dated July 19, 2018,
to Appendix B--Airworthiness Limitations, of Part 2 of the Bombardier
Maintenance Requirements Manual. These temporary revisions describe
airworthiness limitations for inspections of the pressure floor skin.
These documents are distinct since they describe different
airworthiness limitations.
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 agency has been notified of the unsafe condition described in the
MCAI and service information referenced above. The FAA is proposing
this AD because the agency 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 new or more
restrictive airworthiness limitations.
This AD requires 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 (k)(1) of this proposed AD.
The request should include a description of changes to the required
actions that will ensure the continued damage tolerance of the affected
structure.
[[Page 58064]]
Differences Between This Proposed AD and the MCAI or Service
Information
The MCAI specifies that if there are findings from the
airworthiness limitations section (ALS) inspection tasks, corrective
actions must be accomplished in accordance with Bombardier maintenance
documentation. However, this proposed AD does not include that
requirement. Operators of U.S.-registered airplanes are required by
general airworthiness and operational regulations to perform
maintenance using methods that are acceptable to the FAA. The FAA
considers those methods to be adequate to address any corrective
actions necessitated by the findings of ALS inspections required by
this proposed AD.
Costs of Compliance
The FAA estimates that this proposed AD would affect 37 airplanes
of U.S. registry.
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).
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
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.
