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 1work-hour 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

[[Page 31800]]

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.
