Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes

The FAA is adopting a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42-500 and Model ATR72 airplanes. This AD was prompted by reports of heavy corrosion on one of the two lugs of the travel limiting unit (TLU) lever assembly. This AD requires repetitive inspections of the TLU lever assembly for corrosion and, depending on findings, a conductivity test and applicable corrective actions, and prohibits the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
