Except for Confidential Business
Information (CBI) as described in the
following paragraph, and other
information as described in 14 CFR
11.35, the FAA will post all comments
received, without change, as well as a
report summarizing each substantive
public contact with FAA personnel
concerning this proposed rulemaking.
Before acting on this proposal, the FAA

Discussion
The EASA, which is the Technical
Agent for the Member States of the
European Union, has issued EASA AD
2020–0149, dated July 7, 2020 (‘‘EASA
AD 2020–0149’’) (also referred to as the
Mandatory Continuing Airworthiness
Information, or ‘‘the MCAI’’), to correct
an unsafe condition for all Saab AB,
Support and Services Model 340A
(SAAB/SF340A) and SAAB 340B
airplanes; and Model SAAB 2000
airplanes.
This proposed AD was prompted by
reports that certain NLG door
attachment bolts are susceptible to
hydrogen embrittlement. The FAA is
proposing this AD to address NLG door
attachment bolts that were incorrectly
manufactured and are susceptible to
hydrogen embrittlement, decreasing the
mechanical characteristics. This
condition could lead to failure of the
affected parts, which would impair the
link between the NLG and NLG door
and could prevent the extension or
retraction of the NLG, and cause
consequent damage to the airplane and
possible loss of control during landing.
See the MCAI for additional background
information.
FAA’s Determination and Requirements
of This Proposed AD
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 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
in other products of the same type
design.
Proposed AD Requirements
This proposed AD would require
accomplishing the actions specified in
EASA AD 2020–0149 described
previously, as incorporated by
reference, except for any differences
identified as exceptions in the
regulatory text of this AD.
Explanation of Required Compliance
Information
In the FAA’s ongoing efforts to
improve the efficiency of the AD
57169
process, the FAA initially worked with
Airbus and EASA to develop a process
to use certain EASA ADs as the primary
source of information for compliance
with requirements for corresponding
FAA ADs. The FAA has since
coordinated with other manufacturers
and civil aviation authorities (CAAs) to
use this process. As a result, EASA AD
2020–0149 will be incorporated by
reference in the FAA final rule. This
proposed AD would, therefore, require
compliance with EASA AD 2020–0149
in its entirety, through that
incorporation, except for any differences
identified as exceptions in the
regulatory text of this proposed AD.
Using common terms that are the same
as the heading of a particular section in
the EASA AD does not mean that
operators need comply only with that
section. For example, where the AD
requirement refers to ‘‘all required
actions and compliance times,’’
compliance with this AD requirement is
not limited to the section titled
‘‘Required Action(s) and Compliance
Time(s)’’ in the EASA AD. Service
information specified in EASA AD
2020–0149 that is required for
compliance with EASA AD 2020–0149
will be available on the internet at
https://www.regulations.gov by
searching for and locating Docket No.
FAA–2020–0840 after the FAA final
rule is published.
Costs of Compliance
The FAA estimates that this proposed
AD affects 103 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this proposed AD:
ESTIMATED COSTS FOR REQUIRED ACTIONS *
Labor cost
Parts cost
Cost per
product
Cost on U.S.
operators
2 work-hours × $85 per hour = $170 ..........................................................................................
$*
$170 *
$17,510 *
jbell on DSKJLSW7X2PROD with PROPOSALS
* The FAA has received no definitive data that would enable the FAA to provide parts cost estimates for the bolt replacement specified in this
proposed AD.
According to the manufacturer, some
or all of the costs of this proposed AD
may be covered under warranty, thereby
reducing the cost impact on affected
individuals. The FAA does not control
warranty coverage for affected
individuals. As a result, the FAA has
included all known costs in our cost
estimate.
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
VerDate Sep<11>2014
16:25 Sep 14, 2020
Jkt 250001
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
PO 00000
Frm 00022
Fmt 4702
Sfmt 4702
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

Federal Register / Vol. 85, No. 179 / Tuesday, September 15, 2020 / Proposed Rules
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
The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0149, dated July 7, 2020
(``EASA AD 2020-0149'') (also referred to as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for all Saab AB, Support and Services Model 340A (SAAB/
SF340A) and SAAB 340B airplanes; and Model SAAB 2000 airplanes.
This proposed AD was prompted by reports that certain NLG door

NLG and NLG door and could prevent the extension or retraction of the
NLG, and cause consequent damage to the airplane and possible loss of
control during landing. See the MCAI for additional background
information.

FAA's Determination and Requirements of This Proposed AD
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
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 in other
products of the same type design.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in EASA AD 2020-0149 described previously, as incorporated by
reference, except for any differences identified as exceptions in the
regulatory text of this AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA initially worked with Airbus and EASA to develop a
process to use certain EASA ADs as the primary source of information
for compliance with requirements for corresponding FAA ADs. The FAA has
since coordinated with other manufacturers and civil aviation
authorities (CAAs) to use this process. As a result, EASA AD 2020-0149
will be incorporated by reference in the FAA final rule. This proposed
AD would, therefore, require compliance with EASA AD 2020-0149 in its
entirety, through that incorporation, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
Using common terms that are the same as the heading of a particular
section in the EASA AD does not mean that operators need comply only
with that section. For example, where the AD requirement refers to
``all required actions and compliance times,'' compliance with this AD
requirement is not limited to the section titled ``Required Action(s)
and Compliance Time(s)'' in the EASA AD. Service information specified
in EASA AD 2020-0149 that is required for compliance with EASA AD 2020-
0149 will be available on the internet at https://www.regulations.gov
by searching for and locating Docket No. FAA-2020-0840 after the FAA
final rule is published.
Costs of Compliance
The FAA estimates that this proposed AD affects 103 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170........................... $ * $170 * $17,510 *
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data that would enable the FAA to provide parts cost estimates for the bolt
replacement specified in this proposed AD.
According to the manufacturer, some or all of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected individuals. The FAA does not control warranty
coverage for affected individuals. As a result, the FAA has included
all known costs in our cost estimate.
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
[[Page 57170]]
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.

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):
Saab AB, Support and Services (Formerly Known as Saab AB, Saab
Aeronautics): Docket No. FAA-2020-0840; Project Identifier MCAI-
2020-00907-T.
(a) Comments Due Date
The FAA must receive comments by October 30, 2020.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Saab AB, Support and Services (Formerly
Known as Saab AB, Saab Aeronautics) Model 340A (SAAB/SF340A) and
SAAB 340B airplanes; and Model SAAB 2000 airplanes, certificated in
any category.
(d) Subject
Air Transport Association (ATA) of America Code 32, Landing
Gear.
(e) Reason
This AD was prompted by reports that certain nose landing gear
(NLG) door attachment bolts are susceptible to hydrogen
embrittlement. The FAA is issuing this AD to address NLG door
attachment bolts that were incorrectly manufactured and are
susceptible to hydrogen embrittlement, decreasing the mechanical
characteristics. This condition could lead to failure of the
affected parts, which would impair the link between the NLG and NLG
door and could prevent the extension or retraction of the NLG, and
cause consequent damage to the airplane and possible loss of control
during landing.
(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, European Union Aviation Safety Agency (EASA) AD
2020-0149, dated July 7, 2020 (``EASA AD 2020-0149'').
(h) Exceptions to EASA AD 2020-0149
(1) Where EASA AD 2020-0149 refers to its effective date, this
AD requires using the effective date of this AD.
(2) The ``Remarks'' section of EASA AD 2020-0149 does not apply
to this AD.
