SUMMARY: We are adopting a new airworthiness directive (AD) for all
EADS CASA (Type Certificate previously held by Construcciones
Aeron[aacute]uticas, S.A.) Model CN-235, CN-235-100, CN-235-200, and
CN-235-300 airplanes. This AD was prompted by reports of incorrect
electrical polarity connections on engine fire extinguishing discharge
cartridges. This AD requires a one-time inspection to identify the
correct polarity for each pair of electrical connectors on each engine
fire extinguisher cartridge, and repair if necessary. 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.
DATES: This AD becomes effective March 8, 2013.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of March 8,
2013.
ADDRESSES: You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> or in person at the U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.
FOR FURTHER INFORMATION CONTACT: Shahram Daneshmandi, Aerospace
Engineer, International Branch, ANM-116, Transport Airplane
Directorate, FAA, 1601 Lind Avenue SW., Renton, WA 98057-3356;

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on October 18, 2012 (77
FR 64053). That NPRM proposed to correct an unsafe condition for the
specified products. The Mandatory Continuing Airworthiness Information
(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 potential unsafe condition, EADS CASA (Airbus
Military) developed instructions to identify erroneous wiring
polarity installation.
For the reasons described above this [European Aviation Safety
Agency] AD requires a one-time inspection to verify proper
electrical polarity of wiring of each engine fire extinguisher
discharge cartridge and, depending on findings, corrective action
[accomplish the repair].
You may obtain further information by examining the MCAI in the AD
docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (77 FR 64053, October 18,
2012) 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 the AD as proposed.
Costs of Compliance
We estimate that this AD will affect 6 products of U.S. registry.
We also estimate that it will take about 4 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Based on these figures, we estimate the cost of
this AD to the U.S. operators to be $2,040, or $340 per product.
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this AD.
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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM (77 FR 64053, October 18,
2012), the regulatory evaluation, any comments received, and other
information. The street address for the Docket Operations office
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.

electrical connectors on each engine fire extinguisher cartridge, in
accordance with the Instructions of Airbus Military All Operator
Letter 235-020, dated March 9, 2012.
(h) Corrective Action
If, during the inspection required by paragraph (g) of this AD,
erroneous wiring polarity is detected: Before further flight, repair
in accordance with a method approved by the Manager, International
Branch, ANM-116, Transport Airplane Directorate, FAA; or European
Aviation Safety Agency (EASA) (or its delegated agent).
(i) Other FAA AD Provisions
The following provisions also apply to this AD:
