### Airworthiness Directives; SOCATA **Model TBM 700 Airplanes**

**AGENCY** 

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

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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. 

### We are issuing this AD to require actions to correct the unsafe condition on these products.

**DATES** 

### : This AD becomes effective July 6, 2010.

On July 6, 2010, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on March 19, 2010 (75 FR 13239). That NPRM proposed 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.



### Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and the


## 30273 Federal Register / Vol. 75, No. 104 / Tuesday, June 1, 2010 / Rules and Regulations

public interest require adopting the AD as proposed.

Differences Between This 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 required 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 AD.
Costs of Compliance

We estimate that this AD will affect 364 products of U.S. registry. We alsoestimate that it will take about .5 workhour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will 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 parts. 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 this AD to the 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 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 this AD:

(1) Is not a ‘‘ significant regulatory action’’ under Executive Order 12866;

(2) Is not a ‘‘ significant rule ’’ under 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 AD and placed it in the AD Docket. Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647–5527) is in the

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment

■ 

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

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 

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

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

**§ 39.13 [Amended]**

■ 

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

2010–11–15 SOCATA: Amendment 39– 16320; Docket No. FAA–2010–0286; Directorate Identifier 2010–CE–013–AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective July 6, 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 July 6, 2010 (the effective date of this AD), do the following in accordance with DAHER–SOCATA TBM Aircraft Mandatory 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


## 30274 Federal Register / Vol. 75, No. 104 / Tuesday, June 1, 2010 / Rules and Regulations

Bulletin 863520–26–001, dated December 21,
2009.

(3) As of July 6, 2010 (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 withcompliant Halon 1211 (BCF) and reidentified, in accordance with the instructions of L’Hotellier Service Bulletin 863520–26–001, dated December 21, 2009.

### Airworthiness Directives; McDonnell **Douglas Corporation Model MD–11 and MD–11F Airplanes** 

**AGENCY** 

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

**ACTION** 

### : Final rule.

**SUMMARY** 

### : The FAA is superseding an existing airworthiness directive (AD), which applies to certain Model MD–11 and MD–11F airplanes. That AD currently requires a one-time inspection to determine if metallic transitions are installed on wire harnesses of the tail tank fuel transfer pumps, and to determine if damaged wires are present; and repair, if necessary. That AD also requires repetitive inspections of the repaired area; and a permanent modification of the wire harnesses if metallic transitions are not installed, which would terminate the repetitive inspections. This new AD requires modifying the case grounding for the alternate fuel pump of the tail tank, the leak detection thermal switch grounding for the number 2 engine, and wire braid grounding in the empennage and number 2 engine inlet. This AD also removes one airplane from the applicability of the existing AD. This AD results from reports that the wire assembly for the alternate fuel pump is missing a case ground wire, and the lightning protection wire braid for wire assemblies located in the empennage and number 2 engine inlet are grounded improperly. We are issuing this AD to prevent insufficient grounding of the fuel pump, which in combination with an electrical failure within the fuel pump and a compromised electrical bond could cause a fuel tank ignition, resulting in consequent fire or explosion.

**DATES** 

### : This AD becomes effective July 6, 2010.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of July 6, 2010.
