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 


wwoods2 on DSK1DXX6B1PROD with RULES_PART 1
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.

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.

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.

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.
