DEPARTMENT OF AGRICULTURE Animal and Plant Health Inspection Service 9 CFR Part 93 [Docket No. APHIS–2009–0095] RIN 0579–AD10 Importation of Sheep, Goats, and Certain Other Ruminants; Correction Animal and Plant Health Inspection Service, USDA. ACTION: Final rule; correction. AGENCY: The Animal and Plant Health Inspection Service recently issued a final rule that was published in the Federal Register on December 3, 2021. The rule amended the regulations governing the importation of animals and animal products to revise conditions for the importation of live sheep, goats, and certain other nonbovine ruminants, and products derived from sheep and goats, with regard to transmissible spongiform encephalopathies such as bovine spongiform encephalopathy and scrapie. The final rule improperly worded an amendatory instruction that resulted in the unintentional duplication of a sentence and left an obsolete section number in the regulations for the location of the requirements for the importation of sheep and goats from Canada for immediate slaughter. This document corrects that inadvertent error and amends the regulations with the proper wording. DATES: This correction is effective January 3, 2022. FOR FURTHER INFORMATION CONTACT: Dr. Alexandra MacKenzie, Veterinary Medical Officer, Strategy & Policy, VS, APHIS, 4700 River Road, Unit 39, Riverdale, MD 20737–1231; (301) 851– 3300, option 2. SUPPLEMENTARY INFORMATION: On December 3, 2021, we published a final khammond on DSKJM1Z7X2PROD with RULES SUMMARY: VerDate Sep<11>2014 16:32 Dec 30, 2021 Jkt 256001 rule (86 FR 68834–68864) 1 that will be effective on January 3, 2022, and that revised the regulations governing the importation of animals and animal products to revise conditions for the importation of live sheep, goats, and certain other non-bovine ruminants, and products derived from sheep and goats, with regard to transmissible spongiform encephalopathies such as bovine spongiform encephalopathy and scrapie. The amendatory instruction to the Office of the Federal Register (OFR) for the revision to § 93.420 included an instruction to add a sentence after the heading for paragraph (a) introductory text. However, the instruction should have been to revise the first sentence after the heading of paragraph (a) introductory text. By instructing the OFR to add a sentence after the heading of paragraph (a) introductory text as set forth in the rule, rather than revise the existing sentence, we inadvertently instructed the OFR to add a duplicative sentence and leave an obsolete section number in the regulations for the location of the requirements for the importation of sheep and goats from Canada for immediate slaughter. Our intention was to revise the first sentence after the heading for paragraph (a) introductory text and update the section where the requirements for the importation of sheep and goats from Canada for immediate slaughter could be found. Section 93.419 is currently listed in the regulations. However, the final rule removed and reserved § 93.419, and the sentence we added contains the new location of those requirements, which is § 93.435. Accordingly, this rule corrects our inadvertent error. In FR Doc. 2021–26302 appearing on page 68834 in the Federal Register of December 3, 2021, the following correction is made: § 93.420 [Corrected] On page 68859, in the first column, amendatory instruction number 10 is corrected to read as follows: ■ 10. In § 93.420, revise the first sentence of paragraph (a) introductory text to read as follows: ■ 1 To view the final rule, go to https:// www.regulations.gov and enter APHIS–2009–0095 in the Search field.

SUPPLEMENTARY INFORMATION: khammond on DSKJM1Z7X2PROD with RULES Background The Civil Aviation Authority (CAA), which is the airworthiness authority for the United Kingdom, has issued CAA AD G–2021–0014R1–E, dated December 10, 2021 (referred to after this as ‘‘the MCAI’’), to address an unsafe condition for certain Cameron fuel cylinders. The MCAI states: Certain Cameron Hot Air Balloon fuel cylinders are supplied with liquid offtakes VerDate Sep<11>2014 16:32 Dec 30, 2021 Jkt 256001 that consist of a quarter turn ball valve mounted on a flanged adaptor ([part number] P/N CB437, see [CAA AD] figure 1). Two recent batches of these adaptors have been manufactured with non-conforming (undersize) threads. In certain cases, when the minimum sized adaptors are combined with cylinder bosses at maximum tolerance dimension and assembled to fuel cylinders, the thread can impinge (‘‘bottom out’’) on the cylinder boss. Although the required tightening torque value can be achieved at installation, the torque required to unscrew the flange could be below the minimum value. In extreme cases the adaptor may be unscrewed by hand. This condition, if not detected and corrected, could result in an uncontrolled release of liquid propane which in turn could result in a fire hazard that could damage the balloon and its envelope, ultimately leading to a forced emergency landing, during which balloon occupants and persons on the ground could be injured. To address this potential unsafe condition, Cameron Balloons Ltd. issued the Service Bulletin to provide instructions for the removal from service of the affected parts. For the reasons described above, this [CAA] AD retains the requirements of CAA Emergency AD G–2021–0010–E dated 01 October 2021, which required a one-time inspection of each affected fuel cylinder for leakage around the threaded joint between the QSO valve adaptor flange and the cylinder boss and, depending on findings, removal from service of the affected fuel cylinder. The AD also required modification of each fuel cylinder by replacement of the affected part with a serviceable part. Since AD G–2021–0010–E was issued, additional applicability information has been released by the manufacturer, Cameron Balloons Ltd. Additional serial number applicability for CB2902 Cylinders has been identified and added to the list of affected parts. (See [CAA AD] appendix 1). For the reason described above AD 2021– 0010–E, was superseded by AD G–2021– 0014–E which expands the list of affected parts. Since the issue of AD G–2021–0014–E additional information pertaining to the means of visual identification of the affected parts has been released by the manufacturer, Cameron Balloons Ltd. It was also found that that the replacement part specified in the previous [emergency airworthiness directives] EADs, Part No. CB437 ‘Issue G’ did not go into production and instead ‘Issue H’ was produced. For the reasons described above this [CAA] AD has been revised to include additional information in the applicability, the inclusion of photos ([CAA AD] figures 2, 3 and 4) and to reference the correct replacement part number (updated drawing issue). This revised [CAA] AD also introduces editorial changes not affecting the requirements. You may examine the MCAI in the AD docket at https:// www.regulations.gov by searching for and locating Docket No. FAA–2021– 1171. PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 Cameron identified fuel cylinder P/Ns CB2901, CB2902, and CB2903 that had the non-conforming QSO flange adapter P/N CB437 Issue F installed at manufacture. However, the following additional fuel cylinders that were not fitted with flange adapter P/N CB437 Issue F at manufacture may have been later retrofitted with P/N CB437 Issue F: Fuel cylinder P/Ns CB2901, CB2902, and CB2903; stainless steel fuel cylinder P/Ns CB426, CB497, CB599, CB959, CB2088, V20, V30, and V40; titanium fuel cylinder P/Ns CB2380, CB2383, CB2385, CB2387, and T30 (CY–050–A– 001); and ‘‘Worthington’’ aluminum fuel cylinder P/N CB250. The unsafe flange adapter has ‘‘CB437’’ machine-engraved on the part. Flange adapters with ‘‘CB437’’ handstamped on the part or machineengraved with Issue H (‘‘CB437/H’’) or later issue are not subject to the unsafe condition. Related Service Information Under 1 CFR Part 51 The FAA reviewed Cameron Balloons CBL/TN/DCB/3287, Issue C, dated October 14, 2021, which specifies procedures for torque testing fuel cylinders and for replacing the handwheel valve or flange adapter. 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 ADDRESSES. Other Related Service Information The FAA reviewed Cameron Balloons Service Bulletin No. 32, Revision 4, dated November 3, 2021. This service information specifies procedures for identifying affected parts (including figures illustrating both the unsafe and safe flange adapters). This service information also specifies inspecting fuel cylinders for leakage. 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 this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information referenced above. The FAA is issuing this AD after determining the unsafe condition is likely to exist or develop in other products of the same type design. AD Requirements This AD requires accomplishing the actions specified in the service information described previously. E:\FR\FM\03JAR1.SGM 03JAR1 Federal Register / Vol. 87, No. 1 / Monday, January 3, 2022 / Rules and Regulations Differences Between This AD and the MCAI The MCAI identifies affected fuel cylinders by serial number or invoice number, while this AD identifies affected fuel cylinders by the type of engraving of P/N CB437 on the flange adapter. The MCAI applies to hot air balloons and certain airships. This AD only applies to hot air balloons because the airships identified in the MCAI do not have an FAA type certificate. FAA’s Justification and Determination of the Effective Date khammond on DSKJM1Z7X2PROD with RULES Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq.) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for ‘‘good cause,’’ finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because a liquid propane leak could result in an inflight fire, damaging the balloon and leading to a forced emergency landing, which could injure balloon occupants and persons on the ground. In addition, some of the corrective actions must be accomplished before further flight. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forego notice and comment. rule, 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 this final rule 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 https:// www.regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule. 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 AD 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 AD, 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 AD. Submissions containing CBI should be sent to Mike Kiesov, Aviation Safety Engineer, FAA, General Aviation & Rotorcraft Section, International Validation Branch, 901 Locust, Room 301, Kansas City, MO 64106. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required. Comments Invited Costs of Compliance The FAA invites you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA–2021–1171 and Project Identifier MCAI–2021– 01361–Q’’ at the beginning of your comments. The most helpful comments reference a specific portion of the final The FAA estimates that this AD affects 396 fuel cylinders installed on hot air balloons worldwide. The FAA has no way of knowing the number of the hot air balloons of U.S. Registry that may have an affected fuel cylinder installed. The estimated cost on U.S. operators reflects the maximum possible cost based on fuel cylinders worldwide. VerDate Sep<11>2014 16:32 Dec 30, 2021 Jkt 256001 PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 31 The average labor rate is $85 per workhour. The FAA estimates that replacing the QSO flange adapter will take 1 workhour and require parts costing $80, for a cost of $165 per adapter and up to $65,340 for the U.S. fleet. The FAA also estimates that it will take about 1 work-hour per hot air balloon to inspect the fuel cylinder for leakage for a cost of $85 per hot air balloon and up to $33,660 for the U.S. fleet. In addition, the FAA estimates that the torque test will take 1 workhour for a cost of $85 per hot air balloon. The FAA has no way of determining the number of hot air balloons that may need the torque test. 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, and (2) Will not affect intrastate aviation in Alaska.

Airworthiness Directives; Cameron Balloons Ltd. Fuel Cylinders

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Cameron Balloons Ltd. (Cameron) fuel cylinders installed on hot 
air balloons. This AD results from mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI identifies the unsafe condition as quick shut-off 
(QSO) flanged adaptors manufactured with non-conforming (undersized) 
threads. This AD immediately requires either replacing the QSO flange 
adapter or inspecting the fuel cylinder for leakage and taking 
corrective action, and replacing the QSO flange adapter within 4 
months. The FAA is issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective January 18, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 18, 
2022.

SUPPLEMENTARY INFORMATION:

Background

    The Civil Aviation Authority (CAA), which is the airworthiness 
authority for the United Kingdom, has issued CAA AD G-2021-0014R1-E, 
dated December 10, 2021 (referred to after this as ``the MCAI''), to 
address an unsafe condition for certain Cameron fuel cylinders. The 
MCAI states:

    Certain Cameron Hot Air Balloon fuel cylinders are supplied with 
liquid offtakes that consist of a quarter turn ball valve mounted on 
a flanged adaptor ([part number] P/N CB437, see [CAA AD] figure 1). 
Two recent batches of these adaptors have been manufactured with 
non-conforming (undersize) threads.
    In certain cases, when the minimum sized adaptors are combined 
with cylinder bosses at maximum tolerance dimension and assembled to 
fuel cylinders, the thread can impinge (``bottom out'') on the 
cylinder boss. Although the required tightening torque value can be 
achieved at installation, the torque required to unscrew the flange 
could be below the minimum value. In extreme cases the adaptor may 
be unscrewed by hand.
    This condition, if not detected and corrected, could result in 
an uncontrolled release of liquid propane which in turn could result 
in a fire hazard that could damage the balloon and its envelope, 
ultimately leading to a forced emergency landing, during which 
balloon occupants and persons on the ground could be injured.
    To address this potential unsafe condition, Cameron Balloons 
Ltd. issued the Service Bulletin to provide instructions for the 
removal from service of the affected parts.
    For the reasons described above, this [CAA] AD retains the 
requirements of CAA Emergency AD G-2021-0010-E dated 01 October 
2021, which required a one-time inspection of each affected fuel 
cylinder for leakage around the threaded joint between the QSO valve 
adaptor flange and the cylinder boss and, depending on findings, 
removal from service of the affected fuel cylinder. The AD also 
required modification of each fuel cylinder by replacement of the 
affected part with a serviceable part.
    Since AD G-2021-0010-E was issued, additional applicability 
information has been released by the manufacturer, Cameron Balloons 
Ltd. Additional serial number applicability for CB2902 Cylinders has 
been identified and added to the list of affected parts. (See [CAA 
AD] appendix 1).
    For the reason described above AD 2021-0010-E, was superseded by 
AD G-2021-0014-E which expands the list of affected parts.
    Since the issue of AD G-2021-0014-E additional information 
pertaining to the means of visual identification of the affected 
parts has been released by the manufacturer, Cameron Balloons Ltd. 
It was also found that that the replacement part specified in the 
previous [emergency airworthiness directives] EADs, Part No. CB437 
`Issue G' did not go into production and instead `Issue H' was 
produced.
    For the reasons described above this [CAA] AD has been revised 
to include additional information in the applicability, the 
inclusion of photos ([CAA AD] figures 2, 3 and 4) and to reference 
the correct replacement part number (updated drawing issue).
    This revised [CAA] AD also introduces editorial changes not 
affecting the requirements.

    You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
1171.
    Cameron identified fuel cylinder P/Ns CB2901, CB2902, and CB2903 
that had the non-conforming QSO flange adapter P/N CB437 Issue F 
installed at manufacture. However, the following additional fuel 
cylinders that were not fitted with flange adapter P/N CB437 Issue F at 
manufacture may have been later retrofitted with P/N CB437 Issue F: 
Fuel cylinder P/Ns CB2901, CB2902, and CB2903; stainless steel fuel 
cylinder P/Ns CB426, CB497, CB599, CB959, CB2088, V20, V30, and V40; 
titanium fuel cylinder P/Ns CB2380, CB2383, CB2385, CB2387, and T30 
(CY-050-A-001); and ``Worthington'' aluminum fuel cylinder P/N CB250.
    The unsafe flange adapter has ``CB437'' machine-engraved on the 
part. Flange adapters with ``CB437'' hand-stamped on the part or 
machine-engraved with Issue H (``CB437/H'') or later issue are not 
subject to the unsafe condition.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Cameron Balloons CBL/TN/DCB/3287, Issue C, dated 
October 14, 2021, which specifies procedures for torque testing fuel 
cylinders and for replacing the handwheel valve or flange adapter. 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 ADDRESSES.

Other Related Service Information

    The FAA reviewed Cameron Balloons Service Bulletin No. 32, Revision 
4, dated November 3, 2021. This service information specifies 
procedures for identifying affected parts (including figures 
illustrating both the unsafe and safe flange adapters). This service 
information also specifies inspecting fuel cylinders for leakage.

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 this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI and 
service information referenced above. The FAA is issuing this AD after 
determining the unsafe condition is likely to exist or develop in other 
products of the same type design.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information described previously.

[[Page 31]]

Differences Between This AD and the MCAI

    The MCAI identifies affected fuel cylinders by serial number or 
invoice number, while this AD identifies affected fuel cylinders by the 
type of engraving of P/N CB437 on the flange adapter.
    The MCAI applies to hot air balloons and certain airships. This AD 
only applies to hot air balloons because the airships identified in the 
MCAI do not have an FAA type certificate.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because a liquid propane leak could result in an inflight fire, 
damaging the balloon and leading to a forced emergency landing, which 
could injure balloon occupants and persons on the ground. In addition, 
some of the corrective actions must be accomplished before further 
flight. Accordingly, notice and opportunity for prior public comment 
are impracticable and contrary to the public interest pursuant to 5 
U.S.C. 553(b)(3)(B).
    In addition, the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days, 
for the same reasons the FAA found good cause to forego notice and 
comment.

Comments Invited

    The FAA invites you to send any written data, views, or arguments 
about this final rule. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2021-1171 and Project Identifier 
MCAI-2021-01361-Q'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the final rule, 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 
this final rule 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 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this final rule.

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 AD 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 AD, 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 AD. Submissions containing CBI should be sent to Mike 
Kiesov, Aviation Safety Engineer, FAA, General Aviation & Rotorcraft 
Section, International Validation Branch, 901 Locust, Room 301, Kansas 
City, MO 64106. Any commentary that the FAA receives which is not 
specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because FAA has determined 
that it has good cause to adopt this rule without prior notice and 
comment, RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 396 fuel cylinders installed 
on hot air balloons worldwide. The FAA has no way of knowing the number 
of the hot air balloons of U.S. Registry that may have an affected fuel 
cylinder installed. The estimated cost on U.S. operators reflects the 
maximum possible cost based on fuel cylinders worldwide. The average 
labor rate is $85 per work-hour.
    The FAA estimates that replacing the QSO flange adapter will take 1 
work-hour and require parts costing $80, for a cost of $165 per adapter 
and up to $65,340 for the U.S. fleet.
    The FAA also estimates that it will take about 1 work-hour per hot 
air balloon to inspect the fuel cylinder for leakage for a cost of $85 
per hot air balloon and up to $33,660 for the U.S. fleet. In addition, 
the FAA estimates that the torque test will take 1 work-hour for a cost 
of $85 per hot air balloon. The FAA has no way of determining the 
number of hot air balloons that may need the torque test.

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, and
    (2) Will not affect intrastate aviation in Alaska.

System.

(e) Unsafe Condition

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI identifies the unsafe condition as fuel cylinder 
leakage of liquid propane caused by impinged threading on cylinder 
bosses having loose quick shut-off (QSO) flanged adaptors. The FAA 
is issuing this AD to detect and prevent fuel leakage of liquid 
propane. The unsafe condition, if not addressed, could result in a 
fire and consequent emergency landing.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Actions

    (1) Before further flight after the effective date of this AD, 
inspect each fuel cylinder for leakage around the threaded joint 
between the QSO valve adaptor flange and the cylinder boss using 
leak detector fluid.
    (i) If there is any leakage, before further flight, replace the 
fuel cylinder with one that has a handwheel valve or flange adapter 
installed by following the instructions in Section 3.2 or 3.3 of 
Cameron Balloons CBL/TN/DCB/3287, Issue C, dated October 14, 2021.
    (ii) If there is no leakage, before further flight, do a torque 
test of the fuel cylinder by following Section 2 of Cameron Balloons 
CBL/TN/DCB/3287, Issue C, dated October 14, 2021. If the fuel 
cylinder fails the torque test, before further flight, replace the 
fuel cylinder with one that has a handwheel valve or flange adapter 
installed by following the instructions in Section 3.2 or 3.3 of 
Cameron Balloons CBL/TN/DCB/3287, Issue C, dated October 14, 2021.
    (2) Within 4 months after the effective date of this AD, unless 
done before further flight in paragraph (g)(1)(i) or (ii) of this 
AD, replace the flange adapter by following Section 3.3 of Cameron 
Balloons CBL/TN/DCB/3287, Issue C, dated October 14, 2021.
    Note 2 to paragraph (g)(2): You may replace the flange adapter 
in accordance with paragraph (g)(2) of this AD before further flight 
after the effective date of this AD instead of doing the inspection 
in paragraph (g)(1) of this AD.
    (3) As of the effective date of this AD, do not install on any 
hot air balloon a fuel cylinder with a flange adapter with a 
machine-engraved P/N CB437, unless it is engraved Issue H (``CB437/
H'') or later.
