SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain part-numbered
Rockwell Collins Pro Line 4 and Pro
Line 21 FMSs. The NPRM published in
the Federal Register on December 6,
2018 (83 FR 62736).
The NPRM was prompted by a flight
inspection on a Bombardier Model CRJ–
200 airplane, during which Nav Canada,
which is Canada’s civil air navigation
service provider, observed the FMS map
displaying an incorrect turn for the Fort
St. John airport instrument landing
system runway 29 missed approach
while using temperature compensation.
Nav Canada assumed this was only an
issue with the map display and reported
the incident to Rockwell Collins.
Rockwell Collins subsequently
VerDate Sep<11>2014
16:29 May 19, 2020
Jkt 250001
determined that an error in the design
of the Pro Line 4 and Pro Line 21 FMC
software causes changes to the
procedure-defined turn direction when
the procedure has been significantly
modified. The FMS removes the
planned database turn direction when
the flight crew edits the altitude climb
field, and the flight crew may not notice
the change during climb. The FMS also
removes the planned database turn
direction if the flight crew uses the
temperature compensation to edit the
altitude climb field, which may go
unnoticed by the flight crew with the
increased workload involved with a
missed approach procedure. Editing the
altitude or using temperature
compensation does not change the flight
segment. However, due to the design
error, the software thinks the flight
segment has changed. The change of the
planned turn direction can occur for
either left or right turns.
The FMS commanding incorrect turn
direction may result in a collision or
controlled flight into terrain.
The NPRM proposed to require
disabling the automatic temperature
compensation feature of the FMS
through the CSU and revising the AFM
Limitations section. The FAA is issuing
this AD to address the unsafe condition
on these products.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The following presents
the comments received on the NPRM
and the FAA’s response to each
comment.
Request To Remove Requirement To
Disable Temperature Compensation
Bombardier Commercial Aircraft
(Bombardier) and Endeavor Air
(Endeavor) requested the FAA remove
paragraph (g), which proposed to
require disabling the automatic
temperature compensation feature on
the CSU. These commenters stated that
disabling this feature would also disable
the temperature compensation
calculator, which would increase crew
workload and introduce error by
necessitating that pilots manually
calculate this information.
While the FAA agrees that performing
manual temperature compensation
calculations or using standard cold
temperature altitude correction charts
increases flight crew workload, the FAA
finds that these are acceptable piloting
tasks. The FMS and its built-in
temperature compensation feature are
not required under the FAA’s
airworthiness standards; rather, the
temperature compensation feature of the
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
FMS is an aid to the flight crew.
Additionally, disabling the temperature
compensation feature is necessary to
address the unsafe condition. The FAA
did not change the AD based on this
comment.
Request To Revise the Language of the
AFM Limitation Requirement
Bombardier, Endeavor, and Collins
Aerospace (Collins) requested the FAA
revise the AFM Limitations for altitude
edits. The NPRM proposed to require
the limitation in Rockwell Collins
Service Information Letter (SIL) FMC–
XX00–18–1, dated June 27, 2018, which
prohibits editing altitudes on departure,
approach, and missed approach
procedures. The commenters requested
the FAA change the limitation to only
prohibit editing altitudes on departure
and missed approach procedures, and
eliminate the limitation for approach
procedures. Collins stated that following
this limitation during approach prior to
the missed approach could adversely
impact Vertical Navigation (VNAV)
safety and crew workload because it
results in misleading VNAV alerts and
displays prior to the missed approach
point.
The FAA agrees. Rockwell Collins has
revised the SIL and issued SIL FMC–
XX00–18–1, Revision 1, dated February
5, 2019, which contains the limitation
language requested by the commenters.
This final rule requires revising the
AFM to add the information in SIL
FMC–XX00–18–1, Revision 1, dated
February 5, 2019.
Request To Reduce the Compliance
Time for the AFM Revision
Endeavor requested the FAA reduce
the time to revise the AFM from 12
months to 30 days.
The FAA does not agree. The FAA
considered the variety of aircraft types
and operations that would be affected
by this AD and determined a 12-month
compliance time is appropriate for both
the AFM revisions and the requirement
to disable the temperature
compensation feature. The FAA did not
change this AD based on this comment
because 12 months after the effective
date of this AD is necessary to allow the
owner/operator a reasonable amount of
time to perform the hardware
modification. The AFM limitations
cannot be implemented without the
hardware change.
Request To Withdraw the NPRM
WR Ryan stated that this matter is not
serious enough to warrant an AD. The
commenter also stated that this issue is
being exaggerated, as Collins will
eventually fix the problem. The FAA
E:\FR\FM\20MYR1.SGM
20MYR1
Federal Register / Vol. 85, No. 98 / Wednesday, May 20, 2020 / Rules and Regulations
infers the commenter wants the FAA to
withdraw the NPRM.
The FAA does not agree. The FAA
issues an airworthiness directive when
it finds an unsafe condition exists in a
product and the condition is likely to
exist or develop in other products of the
same type design. The FAA has
determined the FMS design error is an
unsafe condition. While an operator
may choose to comply with the service
information released by Rockwell
Collins, not all operators are required to
do so. In order for the corrective actions
in a service document to become
mandatory, and to correct the unsafe
condition identified in the NPRM, the
FAA must issue an AD. The FAA did
not change this AD based on this
comment.
Revise the Costs of Compliance
WR Ryan stated the FAA estimated
labor costs of $85 per work hour in the
NPRM, while the majority of
maintenance shops charge labor rates of
$120 or more an hour. The FAA infers
the commenter wants the FAA to revise
the labor rate in its estimated cost of
complying with the AD.
The FAA does not agree with this
comment. The labor rate of $85 per
work-hour is provided by the FAA
Office of Aviation Policy and Plans for
the FAA to use when estimating the
labor costs of complying with AD
requirements. The FAA did not change
this AD based on this comment.
Authority To Issue the AD/Extension of
Comment Period
Bombardier stated the FAA’s Wichita
ACO Branch lacks the legal authority
under 49 U.S.C. 44701 to issue an AD
addressing a component and requiring
changes to an AFM. Bombardier
requested the FAA’s Wichita ACO
Branch coordinate the proposed AD
with the FAA’s New York ACO Branch
and consider whether the AD should
instead address the aircraft. Bombardier
disagreed with the FAA’s proposed AD
because Transport Canada, the
responsible authority for the state of
design for its airplanes, has already
issued an AD covering this same unsafe
condition. Alternatively, Bombardier
requested an extension to the NPRM
commenting period to allow Bombardier
and the New York ACO Branch to
provide input to the Wichita ACO
Branch.
The FAA does not agree. Although
Canada is the state of design for
Bombardier products, the United States
is the state of design for Rockwell
Collins products. Under the authority of
49 U.S.C. 44701 and the FAA’s
regulations regarding ADs (14 CFR part
39), the FAA issues an AD addressing a
product (aircraft, engine, propeller, or
appliance) that has an unsafe condition
if the condition is likely to exist or
develop in other products of the same
type design. The FMS is an appliance,
as that term is defined in 14 CFR 1.1,
that may be installed in multiple aircraft
types. Contrary to Bombardier’s
suggestion, 49 U.S.C. 44701 does not
require the FAA to adopt the Transport
Canada AD. Rather, 49 U.S.C.
44701(e)(5) permits the FAA to either
accept a foreign AD (under certain
conditions) or issue an FAA AD if
determined necessary for safety. The
Transport Canada AD for this issue
applies only to Bombardier airplanes.
The FAA determined corrective action
is necessary for U.S. operators of all
aircraft with an FMS installed.
The FAA also notes that its Wichita
ACO Branch did not issue the NPRM.
The NPRM was coordinated with all
appropriate FAA offices and
subsequently issued by the Deputy
Director of the Policy and Innovation
Division (AIR–601) of the FAA’s
Aircraft Certification Service. The FAA
has not changed the AD based on this
comment.
Request To Revise Preamble
Information
Collins requested the FAA replace
some of the information in the preamble
with text from Rockwell Collins
Operational Service Bulletin 0166-l7R5.
Collins stated the description in the
NPRM does not accurately describe the
issue. According to Collins, the design
error is that the FMS removes the
planned turn direction if the crew
manually edits or uses temperature
compensation to edit the altitude climb
field. In addition, Collins stated the
FMS does not always turn in an
incorrect direction, but rather only
when the shortest turn differs from the
planned turn.
30599
The FAA partially agrees. For
clarification purposes, the FAA has
revised the referenced text in
accordance with Collins’ comment.
However, the FAA disagrees with
replacing the referenced text with the
description from Rockwell Collins
Operational Service Bulletin 0166–
17R5. The specific language requested
by the commenter is a detailed
engineering description of the FMS
design error that is appropriate for a
service bulletin.
Support of AD Action
The Air Line Pilots Association and
an anonymous commenter supported
the NPRM.
Conclusion
The FAA reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this
final rule with the changes described
previously. The FAA determined that
these changes will not increase the
economic burden on any operator or
increase the scope of this final rule.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Rockwell Collins
Service Information Letter, CSU–XX00–
18–1, dated June 27, 2018. The service
letter contains procedures for disabling
the automatic temperature
compensation option in Pro Line 4 and
Pro Line 21 FMC systems. The FAA also
reviewed Rockwell Collins Service
Information Letter FMC–XX00–18–1,
Revision 1, dated February 5, 2019. The
service letter provides instructions for
revising the Limitations section of the
AFM by adding prohibitions on editing
altitudes for specific Pro Line 4 and Pro
Line 21 Flight Management Systems.
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.
Costs of Compliance

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.

AGENCY:
The FAA is superseding
Airworthiness Directive (AD) 2020–03–
12, which applied to all Airbus SAS
Model A350–941 and –1041 airplanes.
AD 2020–03–12 required revising the
existing airplane flight manual (AFM) to
define a liquid-prohibited zone in the
flight deck and provide procedures
following liquid spillage on the center
pedestal. This AD continues to require
revising the existing AFM, and also
requires installing a removable
integrated control panel (ICP) cover in
the flight deck and further revising the
AFM to include instructions for ICP
cover use, as specified in a European
Union Aviation Safety Agency (EASA)
AD, which is incorporated by reference.
This AD was prompted by the FAA’s
determination that a removable
integrated control panel (ICP) cover
must be installed to prevent damage
from spillage and that the existing AFM
must be revised. The FAA is issuing this
AD to address the unsafe condition on
these products.
DATES: This AD becomes effective June
4, 2020.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of June 4, 2020.
The FAA must receive comments on

The FAA issued AD 2020–03–12,
Amendment 39–19837 (85 FR 7863,
February 12, 2020) (‘‘AD 2020–03–12’’),
which applied to all Airbus SAS Model
A350–941 and –1041 airplanes. AD
2020–03–12 required revising the
existing AFM to define a liquidprohibited zone in the flight deck and
provide procedures following liquid
spillage on the center pedestal. The
FAA issued AD 2020–03–12 to address

shutdown (IFSD), possibly resulting in a
forced landing with consequent damage
to the airplane and injury to occupants.
Actions Since AD 2020–03–12 Was
Issued
Since the FAA issued AD 2020–03–
12, Airbus developed mod 116010,
introducing a removable cover for the
ICP, which protects the ICP completely,
including engine master levers,
thumbwheels, and rotary knob, and
provided modification instructions.
Airbus also published a new AFM
temporary revision (TR) defining a
liquid-prohibited zone in the cockpit,
procedures for ICP removable cover use,
and the procedures to be followed in the
case of inadvertent liquid spillage on
the center pedestal. The FAA has
determined that the removable ICP
cover must be installed and the existing
AFM must be revised to include these
new procedures.
The EASA, which is the Technical
Agent for the Member States of the
European Union, has issued EASA AD
2020–0090, dated April 20, 2020
(‘‘EASA AD 2020–0090’’) (also referred
to as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Airbus SAS Model A350–941
and –1041 airplanes. EASA AD 2020–
0090 supersedes EASA Emergency AD
2020–0020–E, dated February 5, 2020,
corrected February 6, 2020 (which
corresponds to FAA AD 2020–03–12).
This AD was prompted by two reports
of abnormal operation of the
components of the ENG START panel or
Electronic Centralized Aircraft
Monitoring (ECAM) Control Panel (ECP)
due to liquid spillage in the system, and
the subsequent uncommanded engine
IFSD of one engine in each case. This
AD was also prompted by the FAA’s
determination that a removable
integrated control panel (ICP) cover
must be installed to prevent damage
from spillage and that the existing AFM
must be revised. The FAA is issuing this
AD to address the potential for dualengine IFSD, possibly resulting in a
forced landing with consequent damage
to the airplane and injury to occupants.
See the MCAI for additional background
information.
Explanation of Retained Requirements
Although this AD does not explicitly
restate the requirements of AD 2020–
03–12, this AD retains all of the
requirements of AD 2020–03–12. Those
requirements are referenced in EASA
AD 2020–0090, which, in turn, is
referenced in paragraph (g) of this AD.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Rockwell Collins, Inc. (Rockwell Collins) flight management
systems (FMS) installed on airplanes. This AD was prompted by reports
of the flight management computer (FMC) software issuing incorrect turn
commands when the altitude climb field is edited or the temperature
compensation is activated on the FMS control display unit. This AD
requires disabling the automatic temperature compensation feature of
the FMS through the configuration strapping units (CSU) and revising
the airplane flight manual (AFM) Limitations section. The FAA is
issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective June 24, 2020.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain part-numbered
Rockwell Collins Pro Line 4 and Pro Line 21 FMSs. The NPRM published in
the Federal Register on December 6, 2018 (83 FR 62736).
The NPRM was prompted by a flight inspection on a Bombardier Model
CRJ-200 airplane, during which Nav Canada, which is Canada's civil air
navigation service provider, observed the FMS map displaying an
incorrect turn for the Fort St. John airport instrument landing system
runway 29 missed approach while using temperature compensation. Nav
Canada assumed this was only an issue with the map display and reported
the incident to Rockwell Collins. Rockwell Collins subsequently
determined that an error in the design of the Pro Line 4 and Pro Line
21 FMC software causes changes to the procedure-defined turn direction
when the procedure has been significantly modified. The FMS removes the
planned database turn direction when the flight crew edits the altitude
climb field, and the flight crew may not notice the change during
climb. The FMS also removes the planned database turn direction if the
flight crew uses the temperature compensation to edit the altitude
climb field, which may go unnoticed by the flight crew with the
increased workload involved with a missed approach procedure. Editing
the altitude or using temperature compensation does not change the
flight segment. However, due to the design error, the software thinks
the flight segment has changed. The change of the planned turn
direction can occur for either left or right turns.
The FMS commanding incorrect turn direction may result in a
collision or controlled flight into terrain.
The NPRM proposed to require disabling the automatic temperature
compensation feature of the FMS through the CSU and revising the AFM
Limitations section. The FAA is issuing this AD to address the unsafe
condition on these products.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The following presents the comments
received on the NPRM and the FAA's response to each comment.
Request To Remove Requirement To Disable Temperature Compensation
Bombardier Commercial Aircraft (Bombardier) and Endeavor Air
(Endeavor) requested the FAA remove paragraph (g), which proposed to
require disabling the automatic temperature compensation feature on the
CSU. These commenters stated that disabling this feature would also
disable the temperature compensation calculator, which would increase
crew workload and introduce error by necessitating that pilots manually
calculate this information.
While the FAA agrees that performing manual temperature
compensation calculations or using standard cold temperature altitude
correction charts increases flight crew workload, the FAA finds that
these are acceptable piloting tasks. The FMS and its built-in
temperature compensation feature are not required under the FAA's
airworthiness standards; rather, the temperature compensation feature
of the FMS is an aid to the flight crew. Additionally, disabling the
temperature compensation feature is necessary to address the unsafe
condition. The FAA did not change the AD based on this comment.
Request To Revise the Language of the AFM Limitation Requirement
Bombardier, Endeavor, and Collins Aerospace (Collins) requested the
FAA revise the AFM Limitations for altitude edits. The NPRM proposed to
require the limitation in Rockwell Collins Service Information Letter
(SIL) FMC-XX00-18-1, dated June 27, 2018, which prohibits editing
altitudes on departure, approach, and missed approach procedures. The
commenters requested the FAA change the limitation to only prohibit
editing altitudes on departure and missed approach procedures, and
eliminate the limitation for approach procedures. Collins stated that
following this limitation during approach prior to the missed approach
could adversely impact Vertical Navigation (VNAV) safety and crew
workload because it results in misleading VNAV alerts and displays
prior to the missed approach point.
The FAA agrees. Rockwell Collins has revised the SIL and issued SIL
FMC-XX00-18-1, Revision 1, dated February 5, 2019, which contains the
limitation language requested by the commenters. This final rule
requires revising the AFM to add the information in SIL FMC-XX00-18-1,
Revision 1, dated February 5, 2019.
Request To Reduce the Compliance Time for the AFM Revision
Endeavor requested the FAA reduce the time to revise the AFM from
12 months to 30 days.
The FAA does not agree. The FAA considered the variety of aircraft
types and operations that would be affected by this AD and determined a
12-month compliance time is appropriate for both the AFM revisions and
the requirement to disable the temperature compensation feature. The
FAA did not change this AD based on this comment because 12 months
after the effective date of this AD is necessary to allow the owner/
operator a reasonable amount of time to perform the hardware
modification. The AFM limitations cannot be implemented without the
hardware change.
Request To Withdraw the NPRM
WR Ryan stated that this matter is not serious enough to warrant an
AD. The commenter also stated that this issue is being exaggerated, as
Collins will eventually fix the problem. The FAA
[[Page 30599]]
infers the commenter wants the FAA to withdraw the NPRM.
The FAA does not agree. The FAA issues an airworthiness directive
when it finds an unsafe condition exists in a product and the condition
is likely to exist or develop in other products of the same type
design. The FAA has determined the FMS design error is an unsafe
condition. While an operator may choose to comply with the service
information released by Rockwell Collins, not all operators are
required to do so. In order for the corrective actions in a service
document to become mandatory, and to correct the unsafe condition
identified in the NPRM, the FAA must issue an AD. The FAA did not
change this AD based on this comment.
Revise the Costs of Compliance
WR Ryan stated the FAA estimated labor costs of $85 per work hour
in the NPRM, while the majority of maintenance shops charge labor rates
of $120 or more an hour. The FAA infers the commenter wants the FAA to
revise the labor rate in its estimated cost of complying with the AD.
The FAA does not agree with this comment. The labor rate of $85 per
work-hour is provided by the FAA Office of Aviation Policy and Plans
for the FAA to use when estimating the labor costs of complying with AD
requirements. The FAA did not change this AD based on this comment.
Authority To Issue the AD/Extension of Comment Period
Bombardier stated the FAA's Wichita ACO Branch lacks the legal
authority under 49 U.S.C. 44701 to issue an AD addressing a component
and requiring changes to an AFM. Bombardier requested the FAA's Wichita
ACO Branch coordinate the proposed AD with the FAA's New York ACO
Branch and consider whether the AD should instead address the aircraft.
Bombardier disagreed with the FAA's proposed AD because Transport
Canada, the responsible authority for the state of design for its
airplanes, has already issued an AD covering this same unsafe
condition. Alternatively, Bombardier requested an extension to the NPRM
commenting period to allow Bombardier and the New York ACO Branch to
provide input to the Wichita ACO Branch.
The FAA does not agree. Although Canada is the state of design for
Bombardier products, the United States is the state of design for
Rockwell Collins products. Under the authority of 49 U.S.C. 44701 and
the FAA's regulations regarding ADs (14 CFR part 39), the FAA issues an
AD addressing a product (aircraft, engine, propeller, or appliance)
that has an unsafe condition if the condition is likely to exist or
develop in other products of the same type design. The FMS is an
appliance, as that term is defined in 14 CFR 1.1, that may be installed
in multiple aircraft types. Contrary to Bombardier's suggestion, 49
U.S.C. 44701 does not require the FAA to adopt the Transport Canada AD.
Rather, 49 U.S.C. 44701(e)(5) permits the FAA to either accept a
foreign AD (under certain conditions) or issue an FAA AD if determined
necessary for safety. The Transport Canada AD for this issue applies
only to Bombardier airplanes. The FAA determined corrective action is
necessary for U.S. operators of all aircraft with an FMS installed.
The FAA also notes that its Wichita ACO Branch did not issue the
NPRM. The NPRM was coordinated with all appropriate FAA offices and
subsequently issued by the Deputy Director of the Policy and Innovation
Division (AIR-601) of the FAA's Aircraft Certification Service. The FAA
has not changed the AD based on this comment.
Request To Revise Preamble Information
Collins requested the FAA replace some of the information in the
preamble with text from Rockwell Collins Operational Service Bulletin
0166-l7R5. Collins stated the description in the NPRM does not
accurately describe the issue. According to Collins, the design error
is that the FMS removes the planned turn direction if the crew manually
edits or uses temperature compensation to edit the altitude climb
field. In addition, Collins stated the FMS does not always turn in an
incorrect direction, but rather only when the shortest turn differs
from the planned turn.
The FAA partially agrees. For clarification purposes, the FAA has
revised the referenced text in accordance with Collins' comment.
However, the FAA disagrees with replacing the referenced text with the
description from Rockwell Collins Operational Service Bulletin 0166-
17R5. The specific language requested by the commenter is a detailed
engineering description of the FMS design error that is appropriate for
a service bulletin.
Support of AD Action
The Air Line Pilots Association and an anonymous commenter
supported the NPRM.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule with the changes described previously.
The FAA determined that these changes will not increase the economic
burden on any operator or increase the scope of this final rule.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Rockwell Collins Service Information Letter, CSU-
XX00-18-1, dated June 27, 2018. The service letter contains procedures
for disabling the automatic temperature compensation option in Pro Line
4 and Pro Line 21 FMC systems. The FAA also reviewed Rockwell Collins
Service Information Letter FMC-XX00-18-1, Revision 1, dated February 5,
2019. The service letter provides instructions for revising the
Limitations section of the AFM by adding prohibitions on editing
altitudes for specific Pro Line 4 and Pro Line 21 Flight Management
Systems. 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.
Costs of Compliance
The FAA estimates that this AD affects 2,855 products installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this 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
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) 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.
