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 all Turbomeca S.A. 

Arrius Models 2B, 2B1, and 2F 

turboshaft engines. The existing AD 

currently requires replacement of 

injector manifolds and borescopeinspection of the flame tube and the 

high-pressure (HP) turbine area for 

possible damage. Since we issued that 

AD, we received a report that the 

corrective actions of the existing AD 

were insufficient to eliminate the unsafe 

condition. This proposed AD would 

require, depending on the engine model, 

repetitive replacements of fuel injection 

manifolds and the privilege injector, or, 

repetitive replacements of the privilege 

injector. We are proposing this AD to 

prevent an uncommanded in-flight 

shutdown of Arrius 2B1 and 2F 

turboshaft engines and damage to the 

helicopter. 

DATES: We must receive comments on 

this proposed AD by April 8, 2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

On January 9, 2006, we issued AD 

2001–08–14R1, Amendment 39–14423 

(71 FR 2993, January 19, 2006), for all 

Arrius Models 2B, 2B1, and 2F 

turboshaft engines. That AD requires 

replacement of injector manifolds and 

borescope inspection of the flame tube 

and the HP turbine area. That AD 

resulted from reports from the Direction 

Generale de L’Aviation Civile (DGAC), 

which was the airworthiness authority 

for France, of partially or totally blocked 

fuel injection manifolds found during 

inspections at a repair workshop. We 

issued that AD to prevent engine 

flameout during rapid deceleration, or 

the inability to maintain the 2.5 minutes 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

9008 Federal Register / Vol. 78, No. 26 / Thursday, February 7, 2013 / Proposed Rules 

OEI rating, and to prevent injector air 

path cracks, due to blockage of the fuel 

injection manifolds. 

Actions Since Existing AD Was Issued 

Since we issued AD 2001–08–14R1, 

Amendment 39–14423 (71 FR 2993, 

January 19, 2006), Turbomeca reported 

that the corrective actions in that AD 

were insufficient to eliminate the unsafe 

condition. During inspections carried 

out at the repair workshop, some main 

injectors were found totally or partially 

blocked. In response, the European 

Aviation Safety Agency (EASA), which 

is the Technical Agent for the Member 

States of the European Community, 

issued EASA AD 2012–0249, dated 

November 21, 2012, to mandate 

replacements of the fuel injection 

manifolds and privilege injector on 

Arrius 2B1 turboshaft engines, and, 

EASA AD 2012–0150, dated August 8, 

2012, to mandate replacements of the 

privilege injector on Arrius 2F 

turboshaft engines. Also, since we 

issued AD 2001–08–14R1, the Arrius 2B 

engine model is no longer in service and 

has been removed from the engine Type 

Certificate Data Sheet No. E34NE, as 

requested by the manufacturer. 

Relevant Service Information 

We reviewed Turbomeca S.A. Alert 

Mandatory Service Bulletin (MSB) No. 

A319 73 2012, Version I, dated 

November 12, 2012. That Alert MSB 

describes Arrius 2B1 engine procedures 

for replacing, checking, or cleaning the 

injector manifolds and the privilege 

injector. We also reviewed Turbomeca 

S.A. Alert MSB No. A319 73 4001, 

Version K, dated February 10, 2012. 

That Alert MSB describes procedures 

for cleaning or replacing the Arrius 2F 

privilege injector. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and 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, for 

Arrius 2B1 turboshaft engines, initial 

and repetitive replacement of the fuel 

injection manifold and the privilege 

injector within 200 hours time-sincenew (TSN) or since the last 

accomplishment of Turbomeca S.A. 

Alert MSB No. A319 73 2012, Version 

I, dated November 12, 2012, whichever 

occurs first. This proposed AD would 

also require, for Arrius 2F turboshaft 

engines, initial and repetitive 

replacement of the privilege injector 

before exceeding 400 hours TSN or 

since the last accomplishment of 

Turbomeca S.A. Alert MSB No. A319 73 

4001, Version K, dated February 10, 

2012, whichever occurs first. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 38 Arrius 2B1 

engines and about 93 Arrius 2F engines 

installed on helicopters of U.S. registry. 

We also estimate that it would take 

about two hours per engine to replace 

the injector manifolds and about one 

hour per engine to replace the privilege 

injector. The average labor rate is $85 

per hour. Based on these figures, we 

estimate the cost of the proposed AD on 

U.S. operators to be $663,615. 

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 to the extent that it justifies 

making a regulatory distinction, 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

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) 

2001–08–14R1, Amendment 39–14423 

(71 FR 2993, January 19, 2006), and 

adding the following new AD: 

Turbomeca S.A.: Docket No. FAA–2013– 

0024; Directorate Identifier 2000–NE– 

12–AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

AD action by April 8, 2013. 

(b) Affected ADs 

This AD supersedes AD 2001–08–14R1,

privilege injector eligible for installation 

before exceeding 400 operating hours TSN or 

since last inspection on the privilege injector, 

whichever occurs first. 

(2) Borescope-inspect the flame tube and 

the high-pressure turbine area for turbine 

distress. 

(3) Thereafter, within every 400 operating 

hours TIS since last privilege injector 

replacement, replace the privilege injector 

with parts eligible for installation. 

(h) Definition 

For the purposes of this AD, time-inservice (TIS) is defined as the number of 

engine operating hours on the manifolds 

since the manifolds were new or since the 

manifolds were last cleaned, whichever is 

more. 

(i) Installation Prohibitions 

(1) For Arrius 2B1 turboshaft engines, after 

the effective date of this AD, do not install 

fuel injector manifolds or a privilege injector 

on an engine, or an engine on a helicopter, 

unless the fuel injection manifold and 

privilege injector have accumulated fewer 

than 200 operating hours since new, or since 

last inspection. 

(2) For Arrius 2F turboshaft engines, after 

the effective date of this AD, do not install 

a privilege injector on an engine, or an engine 

on a helicopter, unless the privilege injector 

has accumulated fewer than 400 operating 

hours since new, or since last inspection. 

(j) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office,
