ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

ATR–GIE Avions de Transport Re ́gional 

Model ATR42 and ATR72 airplanes. 

This AD was prompted by reports of 

fuel quantity indication malfunctions 

caused by fuel probe failure. This AD 

requires identifying the part number 

and serial number of the fuel probes, 

and replacing the fuel probes if 

necessary. We are issuing this AD to 

prevent fuel probe failure, which could 

lead to undetected fuel starvation and 

consequent dual engine in-flight flameout. 

DATES: This AD becomes effective July 

14, 2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain ATR–GIE Avions de 

Transport Re ́gional Model ATR42 and 

ATR72 airplanes. The NPRM published 

in the Federal Register on August 15, 

2014 (79 FR 48107). The NPRM was 

prompted by reports of fuel quantity 

indication malfunctions caused by fuel 

probe failure. The NPRM proposed to 

require identifying the part number and 

serial number of the fuel probes, and 

replacing the probes if necessary. We 

are issuing this AD to prevent fuel probe 

failure, which could lead to undetected 

fuel starvation and consequent dual 

engine in-flight flame-out. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2014–0075R1, dated April 24, 

2014 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition on certain ATR–GIE 

Avions de Transport Re ́gional Model 

ATR42 and ATR72 airplanes. The MCAI 

states: 

A significant number of fuel probes 

installed on ATR aeroplanes failed during 

production tests and several occurrences of 

fuel quantity indication malfunctions were 

recently reported on in-service aeroplanes. 

The subsequent investigation, conducted 

on the failed parts, confirmed a loss of 

ground connection on the terminal block of 

the fuel probe, due to an incorrect 

application of wiring instructions in 

production during fuel probe manufacturing 

between June 2011 and August 2013. The 

investigation identified a batch of parts, 

suspected to be affected by this 

manufacturing defect. Some of these probes 

were delivered as spares, and operators may 

have installed these probes on their inservice aeroplanes. 

In case an affected fuel probe is installed 

on each wing of an aeroplane, being not 

equipped with an independent fuel low level 

measurement system or an aeroplane 

operated in accordance with ETOPS 

[extended range twin operations] rules, the 

defected fuel probes could indicate a higher 

fuel quantity value than the real quantity of 

the on-board fuel. 

This condition, if not detected and 

corrected, could lead to an undetected fuel 

starvation and consequent dual engine inflight flame out. 


tkelley on DSK3SPTVN1PROD with RULES
32454 Federal Register / Vol. 80, No. 110 / Tuesday, June 9, 2015 / Rules and Regulations 

For the reasons described above, this 

[EASA] AD requires the identification and 

replacement of the affected fuel probes. 

This [EASA] AD is revised to correct 

typographical errors. 

You may examine the MCAI in the 

AD docket on the Internet at http://

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comment 

received on the NPRM (79 FR 48107, 

August 15, 2014) and the FAA’s 

response to the comment. 

Request To Use the Latest Service 

Information 

Empire Airlines requested that we 

revise the NPRM (79 FR 48107, August 

15, 2014) to include revised service 

information. Zodiac Aerospace issued 

Service Bulletin 766983–28–002, 

Revision 1, dated March 24, 2014, to 

correct certain part numbers. Empire 

stated that this change will negate the 

necessity for an alternative method of 

compliance request. 

We agree to include the latest service 

information in this AD, although the 

correct part numbers were identified in 

table 1 to paragraph (g) in the NPRM (79 

FR 48107, August 15, 2014), which will 

remain in this AD. We have also added 

new paragraph (k) in this AD to allow 

the use, before the effective date of this 

AD, of Zodiac Aerospace Service 

Bulletin 766983–28–002, dated October 

15, 2013, for identifying part numbers to 

define serviceable parts. We have 

redesignated subsequent paragraphs 

accordingly. 

Additional Changes to This AD 

We have revised the NPRM (79 FR 

48107, August 15, 2014) to include the 

most updated contact information for 

the service information required by this 

AD, which is: Zodiac Aerospace, 

Technical Publication Department, 61 

Rue Pierre Curie—CS20001, 78373 

Plaisir Cedex, France; phone: +33 (0)1 

61 34 19 24; fax: +33 (0)1 61 34 21 13; 

email: yann.laine@

zodiacaerospace.com; Internet: http://

www.zodiacaerospace.com. 

We have revised the NPRM (79 FR 

48107, August 15, 2014) by removing 

‘‘Services Europe’’ from the service 

information citations, which does not 

need to be included in the service 

information citations in this AD. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (79 FR 

48107, August 15, 2014) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 48107, 

August 15, 2014). 

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 Under 1 

CFR Part 51 

Zodiac Aerospace has issued Service 

Bulletin 766983–28–002, Revision 1, 

dated March 24, 2014. The service 

information describes procedures for an 

inspection for a potential splice 

conductor soldering defect, and 

installing a new splice conductor. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 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 AD. 

Costs of Compliance 

We estimate that this AD affects 81 

airplanes of U.S. registry. 

We also estimate that it will take 

about 2 work-hours per product to 

comply with the basic requirements of 

this AD. The average labor rate is $85 

per work-hour. Required parts will cost 

about $0 per product. Based on these 

figures, we estimate the cost of this AD 

on U.S. operators to be $13,770, or $170 

per product. 

According to the manufacturer, some 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected individuals. We 

do not control warranty coverage for 

affected individuals. As a result, we 

have included all costs in our cost 

estimate. 

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 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 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.

Airworthiness Directives; Airbus 

Helicopters (Previously Eurocopter 

France) Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for Airbus 

Helicopters (previously Eurocopter 

France) Model AS355E, AS355F, 

AS355F1, and AS355F2 helicopters 

with a Fueltron flowmeter installed. 

This AD requires removing each 

flowmeter, replacing the fuel system 

hoses, and disabling the electrical 

connections for the flowmeter 

installation. This AD was prompted by 

a report of particle contamination 

creating an obstruction in a flowmeter 

which resulted in an uncontrolled 

flame-out of the engine. The actions of 

this AD are intended to prevent 

obstruction of the fuel supply to the 

flowmeter, which could result in engine 

flame-out and subsequent loss of control 

of the helicopter. 

DATES: This AD is effective July 14, 

2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain document listed in this AD 

as of July 14, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

On September 15, 2014, at 79 FR 

54925, the Federal Register published 

our notice of proposed rulemaking 

(NPRM), which proposed to amend 14 

CFR part 39 by adding an AD that 

would apply to Airbus Helicopters 

Model AS355E, AS355F, AS355F1, and 

AS355F2 helicopters with a certain 

flowmeter installed. The NPRM 

proposed to require, within 750 hours 

time-in-service, removing the flowmeter 

from each engine, replacing the fuel 

hose with part number (P/N) 704A34– 

416–029 for the left-hand (LH) engine 

and P/N 704A34–416–030 for the righthand (RH) engine, removing the 

flowmeter indicator, and disabling the 

flowmeter electrical connections. The 

proposed requirements were intended to 

prevent obstruction of the fuel supply to 

the flowmeter, which could result in 

engine flame-out and subsequent loss of 

control of the helicopter. 

The NPRM was prompted by AD No. 

2013–0205, dated September 9, 2013, 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union, to correct an unsafe 

condition for Eurocopter (now Airbus 

Helicopters) Model AS355 E, AS355 F, 

AS355 F1, and AS355 F2 helicopters 

with modification 350A070791 

(installation of the Fueltron flowmeter), 

except helicopters with modification 

355A085801 (removal of the Fueltron 

flowmeter). EASA advises, after landing, 

an AS355 helicopter experienced an 

uncontrolled flame-out of the No. 1 

engine caused by particle contamination 

in the fuel that obstructed the Fueltron 

flowmeter. EASA further states that 

because the flowmeter installation is 

identical on both engines, this condition 

could lead to flame-out of both engines 

in flight, possibly resulting in reduced 

control of the helicopter. EASA AD No. 

2013–0205 requires removing the
