AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for Airbus 

Helicopters Model AS355NP helicopters 

with certain fire extinguishing systems. 

This proposed AD would require 

removing and installing the fire 

extinguishing system so that each squib 

on the engine compartment fire 

extinguisher is controlled by a matching 

control button. This proposed AD is 

prompted by the discovery that the lefthand discharge system of the fire 

extinguishing system was incorrectly 

connected to the right-hand engine 

compartment and the right-hand 

discharge system was incorrectly 

connected to the left-hand engine 

compartment. The proposed actions 

would correct the connections and 

would prevent the fire extinguishing 

system discharging to the wrong engine 

compartment, failure of the fire 

extinguishing system to control a fire, 

and subsequent loss of control of the 

helicopter. 

DATES: We must receive comments on 

this proposed AD by June 13, 2016. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, issued EASA Emergency AD No. 

2011–0192–E, dated October 4, 2011, to 

correct an unsafe condition for 

Eurocopter (now Airbus Helicopters) 

Model AS355NP helicopters equipped 

with an Arrius 1A1 engine fire 

extinguishing system through 

production modification OP–3931. 

EASA advises that during an inspection 

of the engine fire extinguishing system 

on an AS355NP helicopter, the left hand 

(LH) fire extinguisher discharge system 

was found connected to the right hand 

(RH) engine compartment and the RH 

discharge system was connected to the 

LH engine compartment. An 

investigation showed that this erroneous 

installation was inherent in Eurocopter 

production modification OP–3931. 

According to EASA, this condition, if 

not detected and corrected, could lead 

to the discharge of the fire extinguisher 

in the wrong engine compartment in the 

event of a fire. Pending the development 

of a modified extinguishing system, 

EASA Emergency AD No. 2011–0192–E 

required installing a placard warning 

the flight crew of the erroneous 

installation until the squibs on each fire 

extinguisher are exchanged. 

After EASA issued Emergency AD No. 

2011–0192–E, Airbus Helicopters 

developed a permanent modification of 

the discharge system to reconfigure the 

position of the squibs on each fire 

extinguisher to line up with the control 

buttons. EASA subsequently issued 

superseding EASA AD No. 2015–0181, 

dated August 31, 2015, to retain the 

requirements of its previous Emergency 

AD and require the modification of the 

engine fire extinguishing discharge 

system within 12 months. 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of France and 

are approved for operation in the United 

States. Pursuant to our bilateral 

agreement with France, EASA, its 

technical representative, has notified us 

of the unsafe condition described in its 

AD. We are proposing this AD because 

we evaluated all known relevant 

information and determined that an 

unsafe condition is likely to exist or 

develop on other products of the same 

type design. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Airbus Helicopters Alert 

Service Bulletin No. AS355–26.00.10, 

Revision 0, dated July 2, 2015 (ASB 

AS355–26.00.10). ASB AS355–26.00.10 

provides procedures for removing the 

fire extinguishing system and reinstalling it in a configuration where the 

squibs match the positioning of the fire 

extinguisher discharge heads. ASB 

AS355–26.00.10 also specifies removing 

any previously-affixed placard on the 

instrument panel and installing new 

discharge system pipes. Helicopters 

with modification 07–3990 installed 

have already complied with ASB 

AS355–26.00.10. 

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. 

Other Related Service Information 

We also reviewed Eurocopter 

Emergency Alert Service Bulletin No. 

26.00.09, Revision 0, dated September 

15, 2011 (EASB 26.00.09), issued prior 

to the permanent modification 

developed by Airbus Helicopters. EASB 

26.00.09 provided procedures for 

interchanging the squibs on each fire 

extinguisher. Until this was 

accomplished, EASB 26.00.09 specified 

affixing a label on the instrument panel 

to make the flight crew aware of the 

crossed connection. 

Proposed AD Requirements 

This proposed AD would require 

within 600 hours time-in-service or at 

the next annual inspection, whichever 

occurs first, removing and correctly 

installing the fire extinguishing system, 

and removing any placards on the 

instrument panel if installed. 

Differences Between This Proposed AD 

and the EASA AD 

The EASA AD requires installing a 

placard on the instrument panel to warn 

the flight crew of the erroneous 

installation until the squibs on each fire 

extinguisher are exchanged, and then, 

within 12 months, removing and reinstalling the fire extinguishing system 

to position the squibs in line with the 

control buttons. This proposed AD 

would not require installation of the 

placards or the temporary exchange of 

the squibs. Also, this proposed AD 

would require removing and reinstalling the fire extinguisher system 

within 600 hours TIS or at the next 

annual inspection, whichever occurs 

first. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 2 helicopters of U.S. 

Registry and that labor costs average $85 

per work hour. We expect that removing 

and installing the fire extinguishing 

system would require 24 work hours 

and required parts would cost $6,367. 

Based on these estimates, we expect a 

total cost of $8,407 per helicopter and 

$16,814 for the U.S. fleet. 

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, 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 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

Flexibility Act. 

We prepared an economic evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model DHC–8–102, 

–103, and –106 airplanes, and Model 

DHC–8–200 and –300 series airplanes. 

This proposed AD was prompted by a 

report of heat damage found on a 

nacelle firewall after an unsuccessful 

engine ground start and several events 

of heat damage found on direct current 

starter/generator terminal block 

assemblies. This proposed AD would 

require an inspection for damage on the 

nacelle firewalls and the terminal block 

assemblies and to make sure the 

insulating sleeves are installed and have 

no damage, and corrective action if 

necessary. We are proposing this AD to 

prevent arcing between the firewall and 

terminal blocks that are missing 

insulating sleeves on the conductive 

bushings, which could, in combination 

with a fuel or hydraulic fluid leak, be 

an ignition source for a fire. 

DATES: We must receive comments on 

this proposed AD by May 27, 2016. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
