## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-300, - 320, and -500 airplanes; and all Model ATR72-101, -102, -201, -202, - 211, -212, and -212A airplanes. This AD was prompted by reports of defective seat tracks. This AD requires a detailed visual inspection of each affected part for deficiencies (sealant blockage and out of tolerance ligaments), and depending on findings, accomplishment of applicable corrective actions, 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.
