Airworthiness Directives; Turbomeca 

S.A. Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to Turbomeca S.A. Arrius 

2F turboshaft engines with P3 air pipe 

(first section) part number (P/N) 0 319 

71 918 0, installed. The existing AD 

currently requires inspections of the P3 

air pipe (first section) and right-hand 

(RH) rear half-wall for proper clearance, 

and readjustment of the pipe if 

necessary. Since we issued that AD, 

Turbomeca S.A. has redesigned the RH 

rear half-wall to ensure sufficient 

clearance between the P3 air pipe (first 

section) and RH rear half-wall. This 

proposed AD would require the same 

inspections for installed engines, 

eliminate readjusting of the P3 air pipe 

(first section), require replacement of 

the RH rear half-wall under certain 

conditions, and adding an optional 

terminating action. We are proposing 

this AD to prevent an uncommanded 

power loss to flight idle, which could 

result in an emergency autorotation 

landing or accident. 

DATES: We must receive comments on 

this proposed AD by February 13, 2012. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to

Discussion 

On June 30, 2009, we issued AD 

2009–14–11, Amendment 39–15961 (74 

FR 34221, July 15, 2009), for Turbomeca 

S.A. Arrius 2F turboshaft engines with 

P3 air pipe (first section), P/N 0 319 71 

918 0, installed. That AD requires 

inspections of the P3 air pipe (first 

section) and RH rear half-wall for 

sufficient clearance. That AD resulted 

from Turbomeca S.A. concluding that 

the tolerance of assembly established 

during the system design, could result 

in some rubbing between parts. Rubs 

between the pipe and the RH rear halfwall may lead to premature wearing and 

finally rupture of the P3 air pipe (first 

section). The loss of P3 air pressure 

would then force the fuel control system 

to idle, which could have a detrimental 

effect in critical phases of flight. We 

issued that AD to prevent an 

uncommanded power loss, which could 

result in an emergency autorotation 

landing or accident. 

Actions Since Existing AD Was Issued 

Since we issued AD 2009–14–11 (74 

FR 34221, July 15, 2009), Turbomeca 

determined that the clearance between 

the P3 air pipe (first section) and the RH 

rear half-wall might change during 

installation of the engine on the 

helicopter. Also since we issued that 

AD, Turbomeca introduced a new 

redesigned RH rear half-wall that 

ensures clearance with the P3 air pipe 

(first section). Also since we issued that 

AD, the European Aviation Safety 

Agency (EASA) superseded AD 2008– 

0134R1, dated February 17, 2009, 

EASA’s new AD, AD 2011–0182, dated 

September 22, 2011, required the same 

corrective actions as this proposed AD. 

Relevant Service Information 

We reviewed Turbomeca S.A. 

Mandatory Service Bulletin (MSB) No. 

319 75 4810, Version B, dated January 

25, 2011. The MSB describes procedures 

for inspecting the clearance between the 

P3 air pipe (first section) and the RH 

rear half-wall. The MSB also requires 

replacing the RH rear half-wall with a 

redesigned RH rear half-wall, P/N 0319 

99 008 0 for engines with no clearance 

between the P3 air pipe (first section) 

and the RH rear half-wall. Also, 

installation of the redesigned RH rear 

half-wall on any engine is terminating 

action to the inspections. EASA 

classified the MSB as mandatory and 

issued AD 2011–0182, dated September 

22, 2011. 

FAA’s Determination 

We are proposing this AD 

supersedure, because we evaluated all 

the relevant information and 


srobinson on DSK4SPTVN1PROD with PROPOSALS
Federal Register / Vol. 76, No. 239 / Tuesday, December 13, 2011 / Proposed Rules 77447 

determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

inspections of the clearance between the 

P3 air pipe (first section) and RH rear 

half-wall for installed engines with RH 

rear half-wall, P/N 0319 99 824 0. This 

proposed AD would also eliminate 

readjustment of the P3 air pipe (first 

section), and define installation of the 

redesigned RH rear half-wall as optional 

terminating action to the inspections. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 120 Arrius 2F 

turboshaft engines installed on 

helicopters of U.S. registry. We also 

estimate that it would take about 2 

work-hours per engine to comply with 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $2,565 per 

engine. Based on these figures, we 

estimate the cost of the proposed AD on 

U.S. operators to be $328,200. Our cost 

estimate is exclusive of possible 

warranty coverage. 

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 

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 that the 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), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 

removing airworthiness directive (AD) 

2009–14–11, Amendment 39–15961 (74 

FR 34221), and adding the following 

new AD: 

Turbomeca S.A.: Docket No. FAA–2009– 

0330; Directorate Identifier 2008–NE– 

43–AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

AD action by February 13, 2012. 

(b) Affected ADs 

This AD supersedes AD 2009–14–11, 

Amendment 39–15961 (74 FR 34221, July 15, 

2009). 

(c) Applicability 

This AD applies to Turbomeca S.A. Arrius 

2F turboshaft engines with right-hand (RH) 

rear half-wall, part number (P/N) 0319 99 824 

0, installed. 

(d) Unsafe Condition 

The P3 air pipe (first section) and the RH 

rear half-wall could rub each other. Rubbing 

between the pipe and the RH rear half-wall 

may lead to rupture of the P3 air pipe (first 

section), which could cause an 

uncommanded power loss to flight idle. We 

are issuing this AD to prevent an 

uncommanded power loss to flight idle, 

which could result in an emergency 

autorotation landing or accident. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(1) For installed engines, within 100 engine 

hours (EH) after the effective date of this AD: 

(i) Inspect the clearance between the P3 air 

pipe (first section) and the RH rear half-wall 

for sufficient clearance (0.5 mm or more). 

(ii) Use paragraph 2.B.(1) of Turbomeca 

Mandatory Service Bulletin (MSB) No. 319 

75 4810, Version B, dated January 25, 2011 

to do the inspection. 

(2) Thereafter, repeat the inspections in 

paragraphs (e)(1)(i) through (e)(1)(ii) of this 

AD as follows: 

(i) At every installation of a RH rear halfwall P/N 0 319 99 824 0 on an installed 

engine, and 

(ii) After every installation or reinstallation 

of an engine with a RH rear half-wall P/N 0 

319 99 824 0 installed. 

(3) If the P3 air pipe (first section) or the 

RH rear half-wall P/N 0 319 99 824 0 is found 

damaged, then before further flight, replace 

the damaged part(s) with parts eligible for 

installation. 

(4) If the P3 air pipe (first section) and the 

RH rear half-wall P/N 0 319 99 824 0 are 

found contacting each other but are not 

damaged, replace the RH rear half-wall with 

a RH rear half-wall eligible for installation. 

(5) If both the P3 air pipe (first section) and 

the RH rear half-wall are found not damaged 

during the inspections specified in paragraph 

(e)(1) or (e)(2) of this AD, and the clearance 

between them is less than 0.5 mm, but they 

are not contacting each other, then repeat the 

inspection in paragraphs (e)(1)(i) and 

(e)(1)(ii) of this AD within every 100 EH. 

(6) Installation of RH rear half-wall, P/N 0 

319 99 008 0, is terminating action to the 

inspections required by paragraph (e) of this 

AD. 

(7) Once a RH rear half-wall, P/N 0 319 99 

008 0, is installed on an engine, do not install 

a RH rear half-wall, P/N 0 319 99 824 0, on 

that engine. 

(f) Definition 

For the purpose of this AD, parts eligible 

for installation is defined as: 

(1) An undamaged P3 air pipe (first 

section). 

(2) An undamaged RH rear half-wall P/N 

0 319 99 824 0. 

(3) A new design RH rear half-wall P/N 0 

319 99 008 0. 

(g) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

may approve alternative methods of 

compliance for this AD. Use the procedures 

found in 14 CFR 39.19 to make your request.

contact the FAA’s Office of Rulemaking 

(202) 267–9677, to request a copy of 

Advisory Circular No. 11–2A, Notice of 

Proposed Rulemaking Distribution 

System, which describes the application 

procedure. 

The Proposal 

This action proposes to amend Title 

14, Code of Federal Regulations (14 

CFR), Part 71 by amending Class E 

airspace extending upward from 700 

feet above the surface to accommodate 

new standard instrument approach 

procedures at Eppley Airfield, Omaha, 

NE. Controlled airspace is needed for 

the safety and management of IFR 

operations at the airport. 

Class E airspace areas are published 

in Paragraph 6005 of FAA Order 

7400.9V, dated August 9, 2011 and 

effective September 15, 2011, which is 

incorporated by reference in 14 CFR 

71.1. The Class E airspace designation 

listed in this document would be 

published subsequently in the Order. 

The FAA has determined that this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. It, 

therefore, (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 describes 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 would 

amend controlled airspace at Eppley 

Airfield, Omaha, NE.
