The agency will also post a report summarizing each substantive verbal contact received about this NPRM. CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this NPRM contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this NPRM, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ‘‘PROPIN.’’ The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this NPRM. Submissions containing CBI should be sent to Jiwan Karunatilake, Aerospace Engineer, Airframe and Propulsion Section, FAA, New York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 516–228–7300; email 9-avsnyaco-cos@faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued TCCA AD CF– 2022–17, dated April 13, 2022 (TCCA AD CF–2022–17) (also referred to after this as the MCAI), to correct an unsafe condition on certain Bombardier, Inc., Model BD–700–2A12 airplanes. The MCAI states that certain fasteners attaching the fuselage skin to stringer 19 between fuselage station (FS) FS945.75 and FS961.45 may be missing. The affected area of the fuselage is a buildup of skin, stringers, and frames, and is identified as a principal structural element for which missing fasteners could significantly reduce safety margins. The FAA is proposing this AD to address missing fasteners, which may subject the skin to inter-rivet buckling under compressive load, creating a hazard of permanent deformation and/ or cracking of the skin. The MCAI requires an inspection for missing fasteners and damage, repair of damage, and installation of any fasteners that were missing. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 The FAA reviewed Bombardier Service Bulletin 700–53–7547, dated July 21, 2021. This service information specifies procedures for inspecting the affected area of the fuselage skin attached to stringer 19 between fuselage station (FS) FS945.75 and FS961.45 for missing fasteners and associated damage, and for installing missing fasteners and repairing any damage. 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 AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in the service information already described. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 11 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: khammond on DSKJM1Z7X2PROD with PROPOSALS ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 5 work-hours × $85 per hour = $425 .......................................................................................... $0 $425 $4,675 The FAA estimates the following costs to do any necessary on-condition actions that would be required based on VerDate Sep<11>2014 17:08 Nov 23, 2022 Jkt 259001 the results of any required actions. The FAA has no way of determining the PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 number of aircraft that might need these on-condition actions: E:\FR\FM\25NOP1.SGM 25NOP1 Federal Register / Vol. 87, No. 226 / Friday, November 25, 2022 / Proposed Rules 72421 ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 27 work-hours × $85 per hour = $2,295 ................................................................................................................. $5,792 $8,087 The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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. khammond on DSKJM1Z7X2PROD with PROPOSALS 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) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA has received a report that a Gulfstream Model G–IV airplane was involved in a fatal accident on December 15, 2021 after spoilers deployed in an asymmetrical manner. The asymmetrical spoiler deployment resulted in in-flight loss of control of the airplane. The fatal flight was the first flight after maintenance actions where the spoiler hydraulic lines were improperly connected (reversed) to the ground spoiler actuator. The ground spoiler actuator configuration allows improper hydraulic line connections during maintenance action as a result of identically threaded connections in close proximity to each other. Improper connection of the ground spoiler hydraulic lines, if not addressed, could result in unintended asymmetrical spoiler deployment, leading to reduced controllability of the airplane, or loss of control of the airplane in-flight or upon landing. FAA’s Determination The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require incorporating corrective actions (includes replacing a ground spoiler actuator hydraulic hose and associated fittings) that physically prevent improper connection of the hydraulic lines to the ground spoiler actuator. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 550 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: E:\FR\FM\25NOP1.SGM 25NOP1

comments reference a specific portion of the proposal, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
the proposal because of those comments.
    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, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to Jiwan 
Karunatilake, Aerospace Engineer, Airframe and Propulsion Section, FAA, 
New York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY 
11590; telephone 516-228-7300; email [email protected]. Any 
commentary that the FAA receives which is not specifically designated 
as CBI will be placed in the public docket for this rulemaking.

Background

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued TCCA AD CF-2022-17, dated April 13, 
2022 (TCCA AD CF-2022-17) (also referred to after this as the MCAI), to 
correct an unsafe condition on certain Bombardier, Inc., Model BD-700-
2A12 airplanes. The MCAI states that certain fasteners attaching the 
fuselage skin to stringer 19 between fuselage station (FS) FS945.75 and 
FS961.45 may be missing. The affected area of the fuselage is a build-
up of skin, stringers, and frames, and is identified as a principal 
structural element for which missing fasteners could significantly 
reduce safety margins. The FAA is proposing this AD to address missing 
fasteners, which may subject the skin to inter-rivet buckling under 
compressive load, creating a hazard of permanent deformation and/or 
cracking of the skin. The MCAI requires an inspection for missing 
fasteners and damage, repair of damage, and installation of any 
fasteners that were missing. See the MCAI for additional background 
information.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Bombardier Service Bulletin 700-53-7547, dated 
July 21, 2021. This service information specifies procedures for 
inspecting the affected area of the fuselage skin attached to stringer 
19 between fuselage station (FS) FS945.75 and FS961.45 for missing 
fasteners and associated damage, and for installing missing fasteners 
and repairing any damage. 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 AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information already described.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 11 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
----------------------------------------------------------------------------------------------------------------
5 work-hours x $85 per hour = $425...........................              $0             $425           $4,675
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

[[Page 72421]]



                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
27 work-hours x $85 per hour = $2,295.          $5,792           $8,087
------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this proposed AD may be covered under warranty, thereby reducing the 
cost impact on affected operators.

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) Would not affect intrastate aviation in Alaska, and
    (3) Would 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
