Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2013–11– 

09 for all Safran Helicopter Engines, 

S.A., Arrius 2B1 and 2F turboshaft 

engines. AD 2013–11–09 required the 

repetitive replacement of the fuel 

injector manifolds and privilege 

injector, or only the privilege injector. 

This AD retains the repetitive hardware 

replacement requirements of AD 2013– 

11–09, but only allows replacement 

pipe injector preferred assembly, part 

number (P/N) 0 319 73 044 0, on the 

Arrius 2F engines. This AD was 

prompted by reports of engine flameouts 

as a result of reduced fuel flow due to 

the presence of coking. We are issuing 

this AD to address the unsafe condition 

on these products. 

DATES: This AD is effective August 9, 

2018.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2013–11–09, 

Amendment 39–17469 (78 FR 32551, 

May 31, 2013), ‘‘AD 2013–11–09’’. AD 

2013–11–09 applied to all Turbomeca 

S.A., Arrius 2B1 and 2F turboshaft 

engines. The NPRM published in the 

Federal Register on August 25, 2017 (82 

FR 40503). The NPRM was prompted by 

a report that the corrective actions of the 

existing AD were insufficient to 

eliminate the unsafe condition. The 

NPRM proposed initial and repetitive 

replacement of the main fuel injector 

half-manifolds and preferred injector for 

Arrius 2B1 turboshaft engines, and 

initial and repetitive replacement of the 

preferred injector and replacing pipe 

injector preferred assemblies, P/N 0 319 

73 835 0, with assembly, P/N 0 319 73 

044 0, for Arrius 2F turboshaft engines. 

We are issuing this AD to address the 

unsafe condition on these products. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Request To Add Safran Service Bulletin 

(SB) 319 73 4085 

An individual commenter requested 

that we incorporate Safran service 

bulletin (SB) No. 319 73 4085, which 

installs new insulating seals on the fuel 

manifold assemblies to limit coking, in 

this AD. The commenter does not 

believe that the proposed AD 

completely corrects the unsafe 

condition, which could result in another 

revised or supersedure AD in the future. 

We disagree. We have not determined 

that the Safran SB No. 319 73 4085, 

Version A, dated March 23, 2016, 

provides an effective terminating action 

to the current AD requirements. We did 

not change this AD. 

Request To Revise Operating Hours in 

Figure 1 

Safran Helicopter Engines stated there 

was an error in Figure 1 to paragraph 

(g)(1)(i) of this AD requiring the postmod TU117 main fuel injector halfmanifold be replaced every 600 

operating hours. They stated the 

replacement interval is 500 hours (plus 

a 100 hour non-cumulative tolerance). 

The application of the non-cumulative 

tolerance specified in the Arrius 2B1 

Maintenance Manual X 319 L5 301 2 

was misinterpreted. 

We agree with commenter’s 

explanation and justification. We 

revised the main fuel injector halfmanifold—post-mod TU117 operating 

hours in Figure 1 to paragraph (g) of this 

AD from 600 operating hours to 500 

operating hours, which is consistent 

with the approved Airworthiness 

Limitations for this engine. We also 

added paragraph (g)(1)(i)(A) to this AD 

that allows a non-cumulative tolerance 

of 100 operating hours to the 

compliance time for the initial 

replacement of the post-mod TU117 

main injector half-manifolds. 

Request To Revise the Compliance 

Requirements 

Safran Helicopter Engines requested 

that we revise paragraph (g)(2)(iii) of 

this AD to replace ‘‘within 16 months 

after the effective date of this AD’’ with 

‘‘August 31, 2018.’’ Safran Helicopter 

Engines asserted that 16 months was 

correct when EASA issued AD 2017– 

0070, but to be consistent with the 

compliance in Safran Helicopter 


sradovich on DSK3GMQ082PROD with RULES
31326 Federal Register / Vol. 83, No. 129 / Thursday, July 5, 2018 / Rules and Regulations 

Engines Mandatory SB No. 319 73 4839, 

this date must be modified to match 

August 31, 2018. 

We disagree. We determined that 16 

months after the effective date of the AD 

is a reasonable timeframe to complete 

the actions and will meet our safety 

objectives. We did not change this AD. 

Request To Revise the Required Actions 

Safran Helicopter Engines requested 

we clarify paragraph (g)(2)(iii) of this 

AD by deleting the words ‘‘before next 

flight.’’ 

We agree with the commenter’s 

request because this change clarifies 

paragraph (g)(2)(iii) of this AD. We 

revised paragraph (g)(2)(iii) of this AD 

as requested. 

Request To Revise Contact Information 

Safran Helicopter Engines requested 

that we revise the contact information 

for service information in paragraph to 

the following: ‘‘Please contact your 

nearest SAFRAN Helicopter Engines 

technical representative or connect to 

www.tools.safran-helicopterengines.com.’’ 

We agree. We revised the contact 

information in the ADDRESSES section of 

this AD to include Safran’s internet 

address: www.tools.safran-helicopterengines.com. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously. 

We have determined that these minor 

changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this AD. 

Related Service Information

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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to engines, propellers, and 

associated appliances to the Manager, 

Engine and Propeller Standards Branch, 

Policy and Innovation Division. 

Regulatory Findings 

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 this AD: 

(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), 

(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.
