Airworthiness Directives; Linstrandt 

Propane Cylinders 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Linstrandt T30 propane cylinders 

installed on hot air balloons. This AD 

results from mandatory continuing 

airworthiness information (MCAI) 

issued by the aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as welding defects on the 

propane cylinder that could result in 

leaking of liquid propane. We are 

issuing this AD to require actions to 

address the unsafe condition on these 

products.

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD No. 

2018–0107, dated May 15, 2018, 

corrected on May 22, 2018 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

A review of cylinder production records 

has shown that the affected cylinders have 

unacceptable welding defects. 

This condition, if not detected and 

corrected, could result in an uncontrolled 

release of liquid propane and consequent fire 

or explosion, with consequent injury to 

balloon occupants and persons on the 

ground. 

To address this potential unsafe condition, 

Cameron Balloons Limited issued the SB, 

providing instructions to remove the affected 

cylinders from service. 

For the reasons described above, this 

[EASA] AD requires replacement of the 

affected cylinders with serviceable parts. 

This [EASA] AD is re-published to correct 

the list of TCDS numbers. The TCDS 

EASA.SAS.BA.001 was erroneously 

introduced, and has been removed, as it is 

not for a hot air balloon. 

You may examine the MCAI on the 

internet at http://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2018–0754. 

FAA’s Determination and Requirements 

of the AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI. We are issuing this AD because 

we evaluated all information provided 

by the State of Design Authority and 

determined the unsafe condition exists 

and is likely to exist or develop on other 

products of the same type design. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because replacement of the propane 

cylinders is required within 30 days. 

Therefore, we find good cause that 

notice and opportunity for prior public 

comment are impracticable. In addition, 

for the reason stated above, we find that 

good cause exists for making this 

amendment effective in less than 30 

days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2018–0754; 

Product Identifier 2018–CE–028–AD’’ at 

the beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD because of those 

comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD.

44816 Federal Register / Vol. 83, No. 171 / Tuesday, September 4, 2018 / Rules and Regulations 

Costs of Compliance 

We estimate that this AD will affect 

10 propane cylinders. We also estimate 

that it would take about 2 work-hours to 

replace a cylinder, at an average labor 

rate of $85 per work-hour, and required 

parts would cost about $3,000 per 

product. Based on these figures, we 

estimate a total cost of $3,170 per 

balloon. 

We know the unsafe condition affects 

10 propane cylinders worldwide; 

however, we have no way of knowing 

the number of hot air balloons on the 

U.S. Registry that may have an affected 

propane cylinder installed. As such, we 

have no way of estimating the potential 

costs of compliance on U.S. 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. 

We are 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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to small airplanes, gliders, 

balloons, airships, domestic business jet 

transport airplanes, and associated 

appliances to the Director of the Policy 

and Innovation Division. 

Regulatory Findings 

We determined that 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) Is not a ‘‘significant rule’’ under 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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.

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as welding 

defects on the propane cylinders that could 

result in leaking of liquid propane. We are 

issuing this AD to prevent leaking of liquid 

propane that could lead to fire or explosion. 

(f) Actions and Compliance 

(1) If any hot air balloon has an affected 

P/N and serial number propane cylinder, as 

listed in paragraph (c) of this AD, within 30 

days after September 24, 2018 (the effective 

date of this AD), remove from service 

Linstrandt T30 propane cylinder P/N 

CY050001 and replace with a propane 

cylinder that is not listed in paragraph (c) of 

this AD. 

(2) After September 24, 2018 (the effective 

date of this AD), do not install on any hot air 

balloon a propane cylinder listed in 

paragraph (c) of this AD. 

(g) Other FAA AD Provisions 

The following provision also applies to this 

AD: 

(1) Alternative Methods of Compliance
