SUPPLEMENTARY INFORMATION: 

Discussion 

This amendment adopts a new AD for 

the specified fire extinguisher. This 

action requires replacing each portable 

fire extinguisher containing 

unapproved, contaminated Halon 1211 

with a portable fire extinguisher 

containing approved Halon 1211. This 

amendment is prompted by an ongoing 

investigation that has established that 

unapproved Halon 1211 has been used 

to fill L’Hotellier portable fire 

extinguishers that are likely to be 

onboard various model helicopters. This 

condition, if not corrected, may reduce 

fire suppression and release toxic fumes 

that would endanger the safety of the 

helicopter and its occupants. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD No. 

2009–0277R1, dated February 5, 2010, 

to correct an unsafe condition for 

L’Hotellier portable fire extinguishers, 

part number (P/N) 863520–00. EASA 

reports that the Civil Aviation Authority 

of the United Kingdom (UK) has 

informed them that significant 

quantities of Halon 1211 gas, 

determined to be outside the required 

specification, have been supplied to the 

aviation industry for use in fire 

extinguishers. Halon 1211 is used in 

portable fire extinguishers, usually 

fitted or stowed in aircraft passenger 

cabins and flight decks. An ongoing 

investigation has established that 

LyonTech Engineering Ltd, a UK-based 

company, has supplied unapproved 

Halon 1211 to L’Hotellier. This Halon 

1211 has subsequently been used to fill 

certain portable fire extinguishers that 

are likely to be installed in or carried on 

various model helicopters including 

Eurocopter France Model EC120B; 

AS350B, BA, B1, B2, B3, and D; 

AS355E, F, F1, N, and NP; and SA341G 

and 342J helicopters, with a portable 

fire extinguisher, P/N 863520–00, with 

a serial-number listed in the L’Hotellier 

service information. 

Related Service Information 

L’Hotellier has issued Service Bulletin 

863520–26–001, dated December 21, 

2009 (SB). The SB specifies returning 

each affected serial-numbered fire 

extinguisher to L’Hotellier. The SB also 

specifies that if a label containing, 

among other information, ‘‘Application 

of SBA 863520–26–001’’ is installed on 

a fire extinguisher, indicating that it has 

been reconditioned with pure Halon 

1211 according to L’Hotellier internal 

procedure ITR70030–00, that 

reconditioned or new fire extinguisher 

can be placed in the helicopter. EASA 

classified this SB as mandatory and 

issued EASA AD No. 2009–0277R1, 

dated February 5, 2010, to ensure the 

continued airworthiness of these 

helicopters. 

FAA’s Evaluation and Unsafe Condition 

Determination 

These products have been approved 

by the aviation authority of France and 

are approved for operation in the United 

States. Pursuant to our bilateral 

agreement with France, EASA, their 

technical representative, has notified us 

of the unsafe condition described in the 

MCAI AD. We are issuing this AD 

because we evaluated all information 

provided by EASA and determined the 

unsafe condition exists and is likely to 

exist or develop on other products of 

these same type designs. 

Differences Between This AD and the 

EASA AD 

We require a 60-day compliance time 

because we have determined that 60 

days will ensure an acceptable level of 

safety versus allowing a 6-month 

compliance time. We have included the 

affected serial numbers of the fire 

extinguishers in the AD rather than 

referring to the SB for the serial 

numbers. 

FAA’s Determination and Requirements 

of This AD 

This unsafe condition is likely to exist 

or develop on other helicopters of these 

same type designs. Therefore, this AD is 

being issued to replace unairworthy fire 

extinguishers with airworthy fire 

extinguishers to prevent using 

contaminated gas that may reduce fire 

suppression and release toxic fumes that 

would endanger the safety of the 

helicopter and its occupants. 

The short compliance time involved 

is required because the previously 

described critical unsafe condition can 

adversely affect the controllability and 

structural integrity of the helicopter in 

the event of a fire. Therefore, replacing 

each unairworthy fire extinguisher with 

an airworthy fire extinguisher is 

required within 60 days, and this AD 

must be issued immediately. 

Since a situation exists that requires 

the immediate adoption of this 

regulation, it is found that notice and 

opportunity for prior public comment 

hereon are impracticable, and that good 

cause exists for making this amendment 

effective in less than 30 days. 

Costs of Compliance 

We estimate that this AD will affect 

about 1,000 helicopters. We also 

estimate that it will take about 1workhour per helicopter to inspect and 

replace the fire extinguisher. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $212 to 

replace each fire extinguisher. Based on 

these figures, we estimate the cost of 

this AD on U.S. operators is $297,000, 

assuming the fire extinguishers are 

replaced on the estimated fleet. 

Comments Invited 

This AD is a final rule that involves 

requirements that affect flight safety and 

was not preceded by notice and an 

opportunity for public comment; 

however, we invite you to submit any 

written data, views, or arguments 

regarding this AD. Send your comments 

to an address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2011–0506; 

Directorate Identifier 2010–SW–020– 

AD’’ at the beginning of your comments. 

We specifically invite comments on the

31800 Federal Register / Vol. 76, No. 106 / Thursday, June 2, 2011 / Rules and Regulations 

overall regulatory, economic, 

environmental, and energy aspects of 

the AD. We will consider all comments 

received by the closing date and may 

amend the AD in light 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 with FAA 

personnel concerning this AD. Using the 

search function of the docket Web site, 

you can find and read the comments to 

any of our dockets, including the name 

of the individual who sent the 

comment. You may review the DOT’s 

complete Privacy Act Statement in the 

Federal Register published on April 11, 

2000 (65 FR 19477–78). 

Regulatory Findings 

We have 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 the regulation: 

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); 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. 

We prepared an economic evaluation 

of the estimated costs to comply with 

this AD. See the AD docket to examine 

the economic evaluation. 

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.
