SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2013-02-12, Amendment 39-17333 (78 FR 7262, 
February 1, 2013) (``AD 2013-02-12''). AD 2013-02-12 applied to all 
EADS CASA (now Airbus Defense and Space S.A.) Model CN-235, CN-235-100, 
CN-235-200, and CN-235-300 airplanes. The NPRM published in the Federal 
Register on June 16, 2017 (82 FR 27631). The NPRM was prompted by 
reports of incorrect electrical polarity connections on engine fire 
extinguishing discharge cartridges. The NPRM proposed to continue to 
require identifying the correct polarity of each pair of electrical 
connectors of the affected engine fire extinguisher cartridge, and 
doing a repair if necessary. The NPRM also proposed to require 
modifying the installation of the fire extinguisher circuit harnesses. 
We are issuing this AD to detect and correct incorrect polarity 
connections, which could prevent the actuation of the discharge 
cartridge in case of automatic fire detection or manual initiation 
during a potential engine fire, and could result in damage to the 
airplane and injury to passengers.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0201, dated October 11, 2016 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus Defense and Space S.A. Model 
CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes. The MCAI 
states:

    Reports have been received of finding wrong electrical polarity 
connections of engine fire extinguishing discharge cartridges on 
CASA CN-235 aeroplanes. The results of the subsequent investigation 
showed that the incorrect discharge cartridge assembly was caused by 
production line errors.
    This condition, if not detected and corrected, could prevent the 
actuation of the discharge cartridge in case of automatic fire 
detection or manual initiation in case of engine fire, possibly 
resulting in damage to the aeroplane and injury to occupants.
    To address this potentially unsafe condition, EADS CASA (Airbus 
Military) developed instructions to identify erroneous wiring 
polarity installation and EASA issued AD 2012-0045 [which correlates 
to FAA AD 2013-02-12, Amendment 39-17333 (78 FR 7262, February 1, 
2013)] to require a one-time inspection to verify proper electrical 
polarity of wiring of each engine fire extinguisher discharge 
cartridge and, depending on findings, corrective action.
    Since [EASA] AD 2012-0045 was issued, Airbus Defence and Space 
(D&S) developed modification of the installation of the fire 
extinguisher circuit harnesses, available for in-service 
installation through Service Bulletin (SB) SB-235-26-0005, which 
represents technical solution for an unsafe condition addressed by 
[EASA] AD 2012-0045 for those aeroplanes. Embodiment of this 
modification introduces a design solution that avoids maintenance 
errors during (re)connecting of the affected fire extinguisher 
circuit harnesses after accomplishment of maintenance tasks or 
functional tests.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2012-0045, which is superseded and

[[Page 43833]]

requires identification of the correct polarity after each 
maintenance action involving (re)connecting of the engine fire 
extinguisher cartridge electrical connector. This [EASA] AD also 
requires modification of the affected fire extinguisher circuit 
harnesses.

    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-2017-
0555.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed EADS CASA Service Bulletin SB-235-26-0005, dated July 
9, 2014. This service information describes procedures for modifying 
the installation of the fire extinguisher circuit harnesses.
    We have also reviewed Airbus Military All Operator Letter 235-020, 
Revision 01, dated November 12, 2013. This service information 
describes procedures for identifying the correct polarity of each pair 
of electrical connectors of the affected engine fire extinguisher 
cartridge, and repairing the erroneous wiring polarity if necessary.
    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.

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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.
