**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule; request for
comments.

**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:

Some digital engine control units (DECUs) used to control MAKILA 2A and MAKILA 2A1 engines have an ambient pressure (P0) sensor with a measurement accuracy that may be outside the range required for satisfactory functioning of the engines throughout the entire operating envelope. In certain extreme flight conditions, the lack of P0 measurement accuracy could potentially cause an engine flameout if the engine is operating on a replacement fuel.

The issue is limited to a batch of 24 DECUs, of which 23 are known to be still in service. Since 01 January 2010, any such DECU returned to an approved repair centre has had its P0 sensor checked and replaced
as necessary. We are issuing this AD to prevent an uncommanded engine in-flight shutdown which could result in a forced autorotation landing or accident.

**DATES :**  This AD becomes effective May 17, 2010.

We must receive comments on this AD by June 1, 2010.

**ADDRESSES :**  You may send comments by any of the following methods:

**SUPPLEMENTARY INFORMATION :** 
Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD 2010–0068– E (corrected), dated April 13, 2010 (referred to after this as ‘‘the MCAI ’’ ), to correct an unsafe condition for the specified products. The MCAI states:

Some DECUs used to control MAKILA 2A and MAKILA 2A1 engines have an ambient pressure (P0) sensor with a measurement accuracy that may be outside the range


### 22694 Federal Register / Vol. 75, No. 83 / Friday, April 30, 2010 / Rules and Regulations

required for satisfactory functioning of the engines throughout the entire operating envelope. In certain extreme flight conditions, the lack of P0 measurement accuracy could potentially cause an engine flameout if the engine is operating on a replacement fuel.

The issue is limited to a batch of 24 DECUs, of which 23 are known to be still in service. Since 01 January 2010, any such DECU returned to an approved repair centre has had its P0 sensor checked and replaced
as necessary.

You may obtain further information by examining the MCAI in the AD docket. FAA’s Determination and Requirements of This AD

This product has been approved by the aviation authority of France and is approved for operation in the United States. Pursuant to our bilateral agreement with France, they have notified us of the unsafe condition described in the MCAI and service information referenced above. 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 the same type design. This AD requires replacement of certain S/N DECUs within 75 flight hours after the effective date of this AD.

Differences Between the AD and the MCAI or Service Information

We have required different actions in this AD from those in the MCAI and service information in order to follow FAA policies. These differences are described in a separate paragraph of the AD. These requirements take precedence over the actions in the MCAI.

FAA’s Determination of the Effective Date

Since no domestic operators use this product, notice and opportunity for public comment before issuing this AD are unnecessary. Therefore, we are adopting this regulation immediately.

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–2010–0411; Directorate Identifier 2010–NE–19–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 with FAA personnel concerning this AD. Using the search function of the Web site, anyone can find and read the comments in any of our dockets, including, if provided, the name of the individual who sent the comment (or signed the comment on behalf of an association, business, labor union, etc.). You may review the DOT’s complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477–78). 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 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 AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, 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:

2010–09–13 Turbomeca: Amendment 39– 16278.; Docket No. FAA–2010–0411; Directorate Identifier 2010–NE–19–AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective May 17, 2010.

Affected ADs

(b) None. Applicability

(c) This AD applies to Turbomeca Makila 2A turboshaft engines with any of the following serial number (S/N) digital engine control units (DECUs) installed, if the DECU has not been returned to an approved repair center since January 1, 2010.

S/N 93 S/N 165 S/N 193 S/N 234 S/N 115 S/N 167 S/N 201 S/N 242 S/N 138 S/N 171 S/N 215 S/N 296 S/N 149 S/N 174 S/N 216 S/N 303 S/N 151 S/N 176 S/N 218 S/N 308 S/N 156 S/N 189 S/N 231 —

These engines are installed on, but not limited to, Eurocopter France EC 225LP helicopters.

Reason

(d) Some DECUs used to control MAKILA 2A and MAKILA 2A1 engines have an ambient pressure (P0) sensor with a measurement accuracy that may be outside the range required for satisfactory functioning of the engines throughout the entire operating envelope. In certain extreme flight conditions, the lack of P0 measurement accuracy could potentially cause an engine flameout if the engine is operating on a replacement fuel.

The issue is limited to a batch of 24 DECUs, of which 23 are known to be still in service. Since 01 January 2010, any such DECU returned to an approved repair centre has had its P0 sensor checked and replaced
as necessary.


### 22695 Federal Register / Vol. 75, No. 83 / Friday, April 30, 2010 / Rules and Regulations

Actions and Compliance

(e) Unless already done, within 75 flight hours after the effective date of this AD, replace the S/N DECUs listed in applicability paragraph (c) of this AD:

(1) With a DECU having a S/N not listed in paragraph (c); or

(2) With a DECU having a S/N listed in paragraph (c), that has been returned to an approved repair center since January 1, 2010.

FAA AD Differences

(f) This AD differs from the Mandatory Continuing Airworthiness Information (MCAI) and/or service information as follows:

(1) EASA AD 2010–0068–E (corrected), dated April 13, 2010, requires, for helicopters having two affected DECUs, that one of the DECUs be replaced before the next flight, and the other DECU be replaced within 75 flight hours after the effective date of the AD.

(2) This AD requires all affected DECUs be replaced within 75 flight hours after the effective date of this AD.

(3) Although EASA AD 2010–0068–E (corrected), dated April 13, 2010, also applies to the Makila 2A1 engine, this AD does not apply to that model because it has no U.S. type certificate.
Alternative Methods of Compliance (AMOCS)

(g) The Manager, Engine Certification Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

**[Docket No. FAA–2009–1002; Airspace Docket No. 09–ANM–18]** 
**Establishment of Class E Airspace; Bonners Ferry, ID** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule.

**SUMMARY :**  This action will establish Class E airspace at Bonners Ferry, ID, to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Boundary County Airport. This will improve the safety and management of Instrument Flight Rules (IFR) operations at the airport.

**DATES :**  Effective date, 0901 UTC, July 29, 2010. The Director of the Federal Register approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments.

**SUPPLEMENTARY INFORMATION :**  History

On November 13, 2009, the FAA published in the Federal Register a notice of proposed rulemaking to amend controlled airspace at Bonners Ferry, ID (74 FR 58570). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received.

Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9T signed August 27, 2009, and effective September 15, 2009, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in that Order.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by establishing Class E airspace extending upward from 700 feet above the surface, at Boundary County Airport, to accommodate IFR aircraft executing new RNAV GPS SIAPs at the airport. This action is necessary for the safety and management of IFR operations. The FAA has determined this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (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) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, section 106 discusses the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in subtitle VII, part A, subpart I, section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it establishes additional controlled airspace at Boundary County Airport, Bonners Ferry, ID. List of Subjects in 14 CFR Part 71
