Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA Emergency AD

PO 00000

EASA AD 20210237E also referred to as the MCAI, to correct an unsafe condition for certain ATRGIE Avions de Transport Regional Model ATR42
200, 300, 320, 400, and 500
airplanes and Model ATR72101, 102, 201, 202, 211, 212, and 212A
airplanes. ATRGIE Avions de Transport Regional Model ATR42400
airplanes are not certificated by the FAA
and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability.
This AD was prompted by a report that the AMM maintenance procedure ATRA26126000ZZZ281ZA
Scheduled Inspection of the Engine Fire Detection Loops incorrectly described a visual inspection of the fire handle. The maintenance procedure specified to verify that the snap wire material attaching the fire handle locking hold-plate was a stainless steel lockwire where it should have specified either an aluminum snap wire or a copper snap wire. If the engine fire handle fails, the flightcrew might not be able to extinguish an engine fire using the engine fire extinguisher system, which is the primary method for extinguishing engine fires. The FAA is issuing this AD to address this condition, which, if not detected and corrected, and combined with an engine fire, could lead to a failure of the engine fire handle to operate, possibly resulting in an uncontrolled engine fire and reduced control of the airplane. See the MCAI for additional background information.
Related Service Information Under 1
CFR Part 51
EASA AD 20210237E specifies procedures for a general visual inspection of both engines fire handles for an incorrect snap wire, and applicable corrective actions. Corrective actions include removing the incorrect snap wire, installing the correct snap wire, and installing the safety seal. This material 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.
FAAs Determination These products have been approved by the aviation authority of another country and are approved for operation in the United States. Pursuant to the FAAs bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI described above.
The FAA is issuing this AD after determining that the unsafe condition
