ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for 

Turbomeca Arrius 2 F turboshaft 

engines. This AD requires removing 

from service certain serial number (SN) 

fuel control units (FCUs) or replacing 

the constant delta pressure diaphragm 

in those FCUs. This AD results from a 

report of an accident in July 2005 

involving a Eurocopter EC120B 

helicopter. We are issuing this AD to 

prevent an uncommanded engine inflight shutdown on a single-engine 

helicopter, resulting in a forced 

autorotation landing or an accident. 

DATES: Effective October 3, 2005. The 

Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the 

regulations as of October 3, 2005. 

We must receive any comments on 

this AD by November 15, 2005.

SUPPLEMENTARY INFORMATION: The 

Direction Generale de L’Aviation Civile 

(DGAC), which is the airworthiness 

authority for France, notified the FAA 

that an unsafe condition may exist on 

Turbomeca Arrius 2 F turboshaft 

engines. The DGAC advises that a 

Eurocopter EC120B helicopter powered 

by an Arrius 2 F turboshaft engine 

experienced an uncommanded in-flight 

engine shutdown. An increase in fuel 

flow led to an increase in gas generator 

and power turbine speeds. Turbine 

blades separated from the disk due to 

the overspeed. Turbomeca determined 

that the fuel flow increase was caused 

by an improperly assembled and 

subsequent failure of the constant delta 

pressure (delta P) diaphragm in the 

FCU. Only certain types of constant 

delta P diaphragms have been identified 

as being capable of being improperly 

assembled. Engine serial numbers that 

may have this type of constant delta P 

diaphragm are listed in Turbomeca 

Alert Mandatory Service Bulletin (MSB) 

No. A319 73 4825, dated August 3, 

2005. The manufacturer is making spare 

FCUs available as fast as possible and 

has established a rotable pool of spares. 

After we reviewed the Turbomeca SB, 

we concluded that using the Turbomeca 

rotable pool of spares as soon as 

practicable effectively manages the risk 

of another failure of the uninspected 

engine population. To this end, we are 

requiring that FCUs identified in the 

Turbomeca SB be replaced as soon as 

practicable but not to exceed February 

28, 2006. Because the practicable 

compliance time may be quite short for 

some operators and the rotable pool 

requires consistent participation, we are 

issuing this AD as final rule; request for 

comments. 

Relevant Service Information 

We have reviewed and approved the 

technical contents of Turbomeca Alert 

MSB No. A319 73 4825, dated August 

3, 2005. That MSB lists the affected 

FCUs by SN and describes procedures 

for removing affected FCUs from service 

or replacing constant delta P 

diaphragms in those FCUs. The DGAC 

classified this service bulletin as 

mandatory and issued AD No. F–2005–

143, dated August 17, 2005, and AD No. 

F–2005–143 R1, dated August 31, 2005, 

in order to ensure the airworthiness of 

these Arrius 2 F turboshaft engines in 

France. 

Federal Register / Vol. 70, No. 179 / Friday, September 16, 2005 / Rules and Regulations 54623 

Bilateral Airworthiness Agreement 

This engine model is manufactured in 

France and is type certificated for 

operation in the United States under the 

provisions of section 21.29 of the 

Federal Aviation Regulations (14 CFR 

21.29) and the applicable bilateral 

airworthiness agreement. Under this 

bilateral airworthiness agreement, the 

DGAC kept the FAA informed of the 

situation described above. We have 

examined the findings of the DGAC, 

reviewed all available information, and 

determined that AD action is necessary 

for products of this type design that are 

certificated for operation in the United 

States. 

FAA’s Determination and Requirements 

of this AD 

The unsafe condition described 

previously is likely to exist or develop 

on other Turbomeca Arrius 2 F 

turboshaft engines of the same type 

design. We are issuing this AD to 

prevent an uncommanded engine inflight shutdown on a single-engine 

helicopter, resulting in a forced 

autorotation landing or an accident. 

This AD requires removing from service 

certain SN FCUs or replacing the 

constant delta P diaphragm in those 

FCUs. You must use the service 

information described previously to 

perform the actions required by this AD. 

FAA’s Determination of the Effective 

Date 

Since an unsafe condition exists that 

requires the immediate adoption of this 

AD, we have found that notice and 

opportunity for public comment before 

issuing this AD are impracticable, and 

that good cause exists for making this 

amendment effective in less than 30 

days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment; 

however, we invite you to send us any 

written relevant data, views, or 

arguments regarding this AD. Send your 

comments to an address listed under 

ADDRESSES. Include ‘‘AD Docket No. 

FAA–2005–22430; Directorate Identifier 

2005–NE–34–AD’’ in the subject line of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of the rule that might suggest a 

need to modify it. 

We will post all comments we 

receive, without change, to http:// 

dms.dot.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 DMS Web site, 

anyone can find and read the comments 

in any of our dockets, including 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) or you may visit 

http://dms.dot.gov. 

Examining the AD Docket 

You may examine the docket that 

contains the AD, any comments 

received, and any final disposition in 

person at the Docket Management 

Facility Docket Offices between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The Docket 

Office (telephone (800) 647–5227) is 

located on the plaza level of the 

Department of Transportation Nassif 

Building at the street address stated in 

ADDRESSES. Comments will be available 

in the AD docket shortly after the DMS 

receives them. 

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 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 a summary of the costs 

to comply with this AD and placed it in 

the AD Docket. You may get a copy of 

this summary by sending a request to us 

at the address listed under ADDRESSES.

Standard Instrument Approach 

Procedures, Weather Takeoff 

Minimums; Miscellaneous 

Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This amendment establishes, 

amends, suspends, or revokes Standard 

Instrument Approach Procedures 

(SIAPs) and/or Weather Takeoff 

Minimums for operations at certain 

airports. These regulatory actions are 

needed because of the adoption of new 

or revised criteria, or because of changes 

occurring in the National Airspace 

System, such as the commissioning of 

new navigational facilities, addition of 

new obstacles, or changes in air traffic 

requirements. These changes are 

designed to provide safe and efficient 

use of the navigable airspace and to 

promote safe flight operations under 

instrument flight rules at the affected 

airports. 

DATES: This rule is effective September 

16, 2005. The compliance date for each 

SIAP and/or Weather Takeoff 

Minimums is specified in the 

amendatory provisions. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of September 

16, 2005. 

ADDRESSES: Availability of matters

SUPPLEMENTARY INFORMATION: This 

amendment to Title 14 of the Code of 

Federal Regulations, Part 97 (14 CFR 

part 97), establishes, amends, suspends, 

or revokes SIAPs and/or Weather 

Takeoff Minimums. The complete 

regulatory description of each SIAP 

and/or Weather Takeoff Minimums is 

contained in official FAA form 

documents which are incorporated by 

reference in this amendment under 5 

U.S.C. 552(a), 1 CFR part 51, and 14 

CFR part 97.20. The applicable FAA 

Forms are identified as FAA Forms 

8260–3, 8260–4, 8260–5 and 8260–15A. 

Materials incorporated by reference are 

available for examination or purchase as 

stated above. 

The large number of SIAPs and/or 

Weather Takeoff Minimums, their 

complex nature, and the need for a 

special format make their verbatim 

publication in the Federal Register 

expensive and impractical. Further, 

airmen do not use the regulatory text of 

the SIAPs and/or Weather Takeoff 

Minimums but refer to their depiction 

on charts printed by publishers of 

aeronautical materials. Thus, the 

advantages of incorporation by reference 

are realized and publication of the 

complete description of each SIAP and/ 

or Weather Takeoff Minimums 

contained in FAA form documents is 

unnecessary. The provisions of this 

amendment state the affected CFR 

sections, with the types and effective 

dates of the SIAPs and/or Weather 

Takeoff Minimums. This amendment 

also identifies the airport, its location, 

the procedure identification and the 

amendment number. 

The Rule 

This amendment to 14 CFR part 97 is 

effective upon publication of each 

separate SIAP and/or Weather Takeoff 

Minimums as contained in the 

transmittal. Some SIAP and/or Weather 

Takeoff Minimums amendments may 

have been previously issued by the FAA 

in a Flight Data Center (FDC) Notice to 

Airmen (NOTAM) as an emergency 

action of immediate flight safety relating 

directly to published aeronautical 

charts. The circumstances which 

created the need for some SIAP, and/or 

Weather Takeoff Minimums 

amendments may require making them 

effective in less than 30 days. For the 

remaining SIAPs and/or Weather 

Takeoff Minimums, an effective date at
