What it does

The FAA is adopting a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42-200, -300, and -320 airplanes. This AD was prompted by a report of an occurrence of a flap asymmetry detector and flap interconnection shaft having worn splines and not engaging mechanically. This AD requires a special detailed inspection (SDI) of the affected flap asymmetry detection mechanism, and applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
