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 cracks in the 

weld between the cylinder valve plate 

and the upper dished end of Cameron 

part number (P/N) CB2990 (Alugas) fuel 

cylinders, which could allow 

uncontrolled fuel leakage of liquid 

propane. This AD requires the removal 

of any installed P/N CB2990 (Alugas) 

fuel cylinder from service before further 

flight. The FAA is issuing this AD to 

address the unsafe condition on these 

products.

SUPPLEMENTARY INFORMATION: 

Background 

The Civil Aviation Authority (CAA), 

which is the airworthiness authority for 

the United Kingdom (UK), has issued 

CAA Emergency AD G–2022–0010–E, 

dated May 12, 2022 (referred to after 

this as ‘‘the MCAI’’), to address an 

unsafe condition for certain Cameron 

fuel cylinders. The MCAI states: 

Five CB2990 (Alugas) cylinders have 

developed cracks in the weld between the 

cylinder valve plate and the upper dished 

end. These cracks allow the release of 

propane from the cylinder. Failures have 

been observed during periodic inspection 

(hydraulic pressure test) and leak test. All the 

in-service failures seen to date have been 

from the batch of cylinders with serial 

numbers starting OC. 

It is likely that other CB2990 cylinders may 

develop similar failures in service. 

To address this potential unsafe condition 

this [UK CAA Emergency AD] * * * is 

issued to temporarily withdraw all CB2990 

(Alugas) cylinders from service pending 

investigation of these failures. 

Cameron Balloons are working urgently 

with the original fabricator to determine the 

cause and scope of these failures. 

You may examine the MCAI in the 

AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0683. 

This condition, if not addressed, 

could lead to fire or explosion and 

consequent emergency landing. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

Related Service Information 

The FAA reviewed Cameron Balloons 

Alert Service Bulletin No. 33, Revision 

0, dated May 4, 2022, which specifies 

procedures for checking the interface 

between the cylinder valve plate and the 

upper dished end of fuel cylinders 

having P/N CB2990 (Alugas) using leak 

detector fluid and emptying the fuel. 

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, before further flight, 

removal from service of any installed P/ 

N CB2990 (Alugas) fuel cylinder. 

Difference Between This AD and the 

MCAI 

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. 

Although the MCAI specifies 

inspecting the fuel cylinders for leaks 

and emptying the fuel, this AD does not 

require those actions. While those 

actions are encouraged for the general 


jspears on DSK121TN23PROD with RULES1
36054 Federal Register / Vol. 87, No. 115 / Wednesday, June 15, 2022 / Rules and Regulations 

safety related to the leakage of liquid 

propane from these fuel cylinders once 

they have been removed from the 

balloon, those actions are not required 

to address the unsafe condition 

identified in this AD. 

Interim Action 

The FAA considers this AD to be an 

interim action. If additional data is 

received by the UK CAA enabling the 

development of an inspection of the 

affected fuel cylinders, the FAA may 

take further rulemaking action. 

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 on 

the fuel cylinder could lead to an inflight fire or explosion, damaging the 

hot air balloon and leading to a forced 

emergency landing, which could injure 

balloon occupants and persons on the 

ground. Additionally, 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–2022–0683 

and Project Identifier MCAI–2022– 

00631–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 696 fuel cylinders installed on 

hot air balloons worldwide. The FAA 

has no way of knowing the number of 

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 workhour. 

The FAA estimates that removing the 

affected fuel cylinder will take 1 workhour costing $85, for a cost of up to 

$59,160 for the U.S. fleet. The FAA 

estimates that installing a non-affected 

fuel cylinder will take 1 work-hour 

costing $85 and will cost $3,200 per fuel 

cylinder, for a cost of up to $2,286,360 

for the U.S. fleet. 

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; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 777 

airplanes. This AD was prompted by a 

report of the loss of the nuts at all four 

fastener locations common to the 

outboard flap inboard support rear spar 

attachment fittings, which affects the 

retention feature of the fasteners and 

leaves the fasteners susceptible to 

migrating out of the joint. This AD 

requires repetitive detailed inspections 

for discrepancies of the fasteners and 

shim of the wing rear spar at certain 

outboard flap supports; a detailed 

inspection for damage of the shim, flap 

support mechanism, and wing lower 

skin; installation of new fasteners and 

shims; and repair or replacement of 

damaged parts. The FAA is issuing this 

AD to address the unsafe condition on 

these products. 

DATES: This AD is effective July 20, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of July 20, 2022.
