Operators of older ATRs told to check engine fire-extinguisher systems
Operators of ATR turboprops are being instructed to conduct urgent checks for possible wrongly-assembled valves on the engine fire-extinguishing systems. The European Union Aviation Safety Agency has ordered the checks in an emergency directive which covers both the ATR 42 and 72, up to the -500 variants. EASA states that a scheduled maintenance operation identified incorrect marking and assembly of two-way valves in the left- and right-hand fire-extinguishing systems. As a result, says the regulator, the systems “did not operate as intended”. Similarly-affected systems could suffer from “reduced performance” in the event of an engine fire, it adds. ATR has issued inspection and rework instructions for the parts involved.<br/>
