Known as Construcciones 

Aeronauticas, S.A.) Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Airbus Defense and Space S.A. 

(formerly known as Construcciones 

Aeronauticas, S.A.) Model CN–235–200 

and CN–235–300 airplanes. This 

proposed AD was prompted by reports 

of false engine fire warning events, 

which consequently led to engine inflight shut down. This proposed AD 

would require modification of the 

location and routing of the engine fire 

detection system. We are proposing this 

AD to prevent unnecessary engine inflight shut down, which could result in 

reduced controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by December 28, 

2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2015–0011, dated January 20, 

2015 (referred to after this as the 

Mandatory Continuing Airworthiness 

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

an unsafe condition for certain Defense 

and Space S.A. (formerly known as 

Construcciones Aeronauticas, S.A.) 

Model CN–235–200 and CN–235–300 

airplanes. The MCAI states: 

Several cases of false engine fire warning 

events were reported, which consequently 

led to engine in-flight shut down (IFSD) 

executed by the flightcrew using the 

appropriate emergency procedures. 

Subsequent investigation determined that 

these false engine fire warnings were the 

result of insufficient insulation capability of 

the engine fire detection system. This 

allowed penetration of moisture into the fire 

detector connectors, reducing the insulation 

resistance between the inner electrode and 

connector housing below the required values. 

This condition, if not corrected, could lead 

to further cases of unnecessary engine IFSD, 

possibly resulting in reduced control of the 

aeroplane. 

To address this potential unsafe condition, 

EADS–CASA issued Service Bulletin (SB) 

SB235–26–0006 providing modification 

instructions. 

For the reasons described above, this 

[EASA] AD requires modification of the 

location and routing of the engine fire 

detection system. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

4809. 

Related Service Information Under 1 

CFR Part 51 

EADS CASA has issued Service 

Bulletin SB–235–26–0006, dated July 8, 

2014. The service information describes 

procedures for modifying the engine fire 

detection system. 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 another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of these same 

type designs. 

Costs of Compliance 

We estimate that this proposed AD 

affects 24 airplanes of U.S. registry. 

We also estimate that it would take 

about 75 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 80, No. 218 / Thursday, November 12, 2015 / Proposed Rules 69899 

parts would cost about $1,577 per 

product. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be $190,848, or $7,952 

per product. 

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.
