Airworthiness Directives; Airbus Defense and Space S.A. (Formerly 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 in-flight 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 in-flight 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 methods:

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
Page 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.

The Proposed Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 Amended
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):
Airbus Defense and Space S.A. (formerly known as Construcciones Aeronauticas, S.A.): Docket No. FAA-2015-4809; Directorate Identifier 2015-NM-012-AD.
(a) Comments Due Date
We must receive comments by December 28, 2015.

(d) Subject
Air Transport Association (ATA) of America Code 26, Fire Protection.
(e) Reason
This AD was prompted by reports of false engine fire warning events, which consequently led to engine in-flight shut down. We are issuing this AD to prevent unnecessary in-flight-shutdown of an engine, which could result in reduced controllability of the airplane.

(h) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

If sending information directly to the International Branch, send it to ATTN: Shahram Daneshmandi, Aerospace Engineer, International Branch, ANM-116, Transport Airplane Directorate, FAA, 1601 Lind Avenue SW., Renton, WA 98057-3356; telephone 425-227-1112; fax 425-227-1149. Information may be emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office. The AMOC approval letter must specifically reference this AD.
(2) Contacting the Manufacturer: For any requirement in this AD to obtain corrective actions from a manufacturer, the action must be accomplished using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or EADS CASA's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
