Models named: CN-235, CN-235-100, CN-235-200, CN-235-300. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all EADS CASA (Type Certificate previously held by Construcciones Aeronáuticas, S.A.) Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes, certificated in any category, all serial numbers.

Compliance

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

Required actions

Within 30 days after the effective date of this AD, do a one-time inspection to identify the correct polarity for each pair of 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.

Unsafe condition

This AD was prompted by reports of incorrect electrical polarity connections on engine fire extinguishing discharge cartridges. 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.

Affected ADs

None.
