## Abstract

We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB139 and AW139 helicopters. This AD requires visually inspecting certain subfloor frames for a crack. This AD was prompted by reports of cracks on in-service helicopters. The actions of this AD are intended to detect or prevent a crack in the subfloor frame, which could result in failure of the pilot and co-pilot pedal support frame and subsequent loss of control of the helicopter.
