Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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 describes the unsafe condition as:

The Civil Aviation Authority of the United Kingdom (UK) has informed EASA 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 extinguishing equipment. Halon 1211 (BCF) is used in portable fire extinguishers, usually fitted or stowed in aircraft passenger cabins and flight decks.

EASA published Safety Information Bulletin (SIB) 2009-39 on 23 October 2009 to make the aviation community aware of this safety concern.

The results of the ongoing investigation have now established that LyonTech Engineering Ltd, a UK-based company, has supplied further consignments of Halon 1211 (BCF) to L'Hotellier that do not meet the required specification. This Halon 1211 has subsequently been used to fill certain P/N 863520-00 portable fire extinguishers that are now likely to be installed in or carried on certain TBM700 aeroplanes.

The contaminated nature of this gas, when used against a fire, may provide reduced fire suppression, endangering the safety of the aeroplane and its occupants. In addition, extinguisher activation may lead to release of toxic fumes, possibly causing injury to aeroplane occupants.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

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.: 2010-0012, dated February 5, 2010 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

The Civil Aviation Authority of the United Kingdom (UK) has informed EASA 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 extinguishing equipment. Halon 1211 (BCF) is used in portable fire extinguishers, usually fitted or stowed in aircraft passenger cabins and flight decks.

EASA published Safety Information Bulletin (SIB) 2009-39 on 23 October 2009 to make the aviation community aware of this safety concern.

The results of the ongoing investigation have now established that LyonTech Engineering Ltd, a UK-based company, has supplied further consignments of Halon 1211 (BCF) to L'Hotellier that do not meet the required specification. This Halon 1211 has subsequently been used to fill certain P/N 863520-00 portable fire extinguishers that are now likely to be installed in or carried on certain TBM700 aeroplanes.

The contaminated nature of this gas, when used against a fire, may provide reduced fire suppression, endangering the safety of the aeroplane and its occupants. In addition, extinguisher activation may lead to release of toxic fumes, possibly causing injury to aeroplane occupants.

For the reason described above, this EASA AD requires the identification and removal from service of certain batches of fire extinguishers and replacement with serviceable units.

You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

DAHER-SOCATA has issued TBM Aircraft Service Bulletin SB 70-183, dated January 2010.

L'Hotellier has issued Service Bulletin 863520-26-001, dated December 21, 2009.

The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the Proposed 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 Start Printed Page 13240MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

Differences Between This Proposed AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD.

Costs of Compliance

We estimate that this proposed AD will affect 364 products of U.S. registry. We also estimate that it would take about .5 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $0 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $15,470, or $43 per product.

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.

Regulatory Findings

We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed 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 a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

Start Part

PART 39—AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

Start Authority

Authority: 49 U.S.C. 106(g), 40113, 44701.

End Authority
[Amended]

2. The FAA amends § 39.13 by adding the following new AD:

SOCATA: Docket No. FAA-2010-0286; Directorate Identifier 2010-CE-013-AD.

Comments Due Date

(a) We must receive comments by May 3, 2010.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Model TBM 700 airplanes, all serial numbers (SNs), that:

(1) Are certificated in any category; and

(2) Are equipped with part number (P/N) 863520-00 portable fire extinguishers, serial numbers (S/N) as listed in L'Hotellier Service Bulletin 863520-26-001, dated December 21, 2009.

Subject

(d) Air Transport Association of America (ATA) Code 26: Fire Protection.

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

The Civil Aviation Authority of the United Kingdom (UK) has informed EASA 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 extinguishing equipment. Halon 1211 (BCF) is used in portable fire extinguishers, usually fitted or stowed in aircraft passenger cabins and flight decks.

EASA published Safety Information Bulletin (SIB) 2009-39 on 23 October 2009 to make the aviation community aware of this safety concern.

The results of the ongoing investigation have now established that LyonTech Engineering Ltd, a UK-based company, has supplied further consignments of Halon 1211 (BCF) to L'Hotellier that do not meet the required specification. This Halon 1211 has subsequently been used to fill certain P/N 863520-00 portable fire extinguishers that are now likely to be installed in or carried on certain TBM700 aeroplanes.

The contaminated nature of this gas, when used against a fire, may provide reduced fire suppression, endangering the safety of the aeroplane and its occupants. In addition, extinguisher activation may lead to release of toxic fumes, possibly causing injury to aeroplane occupants.

For the reason described above, this EASA AD requires the identification and removal from service of certain batches of fire extinguishers and replacement with serviceable units.

Actions and Compliance

(f) Unless already done, within 3 months after the effective date of this AD, do the following in accordance with DAHER-SOCATA TBM Aircraft Service Bulletin SB 70-183, dated January 2010:

(1) Inspect the fire extinguisher(s) installed or carried on board the airplane for any P/N and S/N fire extinguisher listed in L'Hotellier Service Bulletin 863520-26-001, dated December 21, 2009; and

(2) If, as a result of the inspection required by paragraph (f)(1) of this AD, you find any fire extinguisher listed in L'Hotellier Service Bulletin 863520-26-001, dated December 21, 2009, before further flight, remove it from the airplane and replace it with a serviceable unit in accordance with L'Hotellier Service Bulletin 863520-26-001, dated December 21, 2009.

(3) As of the effective date of this AD, do not install any fire extinguisher listed in L'Hotellier Service Bulletin 863520-26-001, dated December 21, 2009, on any airplane, unless it has been overhauled with compliant Halon 1211 (BCF) and re-identified, in accordance with the instructions of L'Hotellier Service Bulletin 863520-26-001, dated December 21, 2009.Start Printed Page 13241
