Resumen
We are adopting a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-300 and -500 airplanes and Model ATR72-202 and -212A airplanes. This AD requires identifying the serial number of the dual distributor valve (DDV), and replacement of affected DDVs. This AD was prompted by an investigation performed on a failed DDV that revealed a nonconformity of crimping on an internal valve. We are issuing this AD to address the unsafe condition on these products.
