hour. Parts would cost about $0 per 

engine. Based on these figures, we 

estimate the total cost of this proposed 

AD to U.S. operators to be $111,095. 

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 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 this 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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Turbomeca S.A. MAKILA 2A and 

MAKILA 2A1 turboshaft engines. This 

proposed AD was prompted by two 

occurrences of crack initiation on a 

ferrule of the diffuser. This proposed 

AD would require repetitive diffuser 

inspections and replacement of those 

diffusers that fail inspection. We are 

proposing this AD to prevent rupture of 

the ferrule of the diffuser, which could 

result in engine fire and damage to the 

helicopter.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2015– 

0209, dated October 16, 2015 (referred 

to hereinafter as ‘‘the MCAI’’), to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Two occurrences of crack initiation were 

reported on a ferrule of diffuser part number 

(P/N) 0298210100, which propagated and led 

to the ferrule rupture. The investigation 

shows in both cases that the ruptured ferrule 

contacted and punctured the main fuel 

supply line, resulting in a fuel leak. This 

condition, if not detected and corrected, 

could lead to an engine fire, consequently 

triggering an uncommanded engine in flight 

shut down, possibly resulting in an 

emergency landing. Prompted by these 

occurrences, Turbomeca published 

Mandatory Service Bulletin (MSB) No. 298 

72 2832 to provide repetitive inspection 

instructions. 

This proposed AD would require 

repetitive inspections of the affected 

diffuser and removal of those diffusers 

that fail the required inspection. You 

may obtain further information by 

examining the MCAI in the AD docket 

on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

8257. 

Related Service Information Under 1 

CFR Part 51 

Turbomeca S.A. has issued Alert 

Mandatory Service Bulletin (MSB) No. 

A298 72 2832, Version B, dated October 

12, 2015. The Alert MSB describes 

procedures for repetitive inspections of 

the affected diffuser and depending on 

findings, accomplishment of the 

corrective action(s). 

Turbomeca S.A. has issued Service 

Bulletin (SB) No. 298 72 2833, Version 

A, dated July 29, 2015. The SB identifies 

post-TU52 HP gas generator modules 

that have been released with a new 

ferrule after repair or overhaul in a 

Repair Center. When applying Alert 

Mandatory Service Bulletin (MSB) No. 

A298 72 2832, it is necessary to know 

if an HP gas generator module released 

by a Repair Center is equipped with a 

new ferrule. 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section of 

this NPRM. 

FAA’s Determination and Requirements 

of This Proposed 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 the European 

Community, EASA has notified us of 

the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing 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 

proposed AD would require repetitive 

inspections of the affected diffuser and 

depending on findings, accomplishment 

of the corrective action(s). 

Costs of Compliance 

We estimate that this proposed AD 

affects 10 engines installed on 

helicopters of U.S. registry. We also 

estimate that it would take about 2 

hours per engine to comply with this 

proposed AD. The average labor rate is 

$85 per hour. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be $1,700. 

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

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

substantial direct effect on the States, on 

the relationship between the national 

Government and the States, or on the

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for Airbus 

Helicopters Model AS 365 N3 

helicopters. This proposed AD would 

require inspecting the cabin and cockpit 

for labels, placards, or markings that

placards, or markings that are in an 

incorrect location, and installing 

placards where they are missing. This 

proposed AD is prompted by the 

determination that placards had not 

been installed according to 

specifications on newly manufactured 

helicopters. The proposed actions are 

intended to provide exit procedures 

during an emergency.
