Airworthiness Directives; Aviointeriors S.p.A. (formerly ALVEN), Series 312 Box Mounted Seats

The FAA is adopting a new airworthiness directive (AD) for Aviointeriors S.p.A. (formerly ALVEN), series 312 box mounted seats. This AD requires initial and repetitive inspections of the seat attachments for cracks, and if necessary, replacing the attachments. This AD results from 10 reports of cracked attachments of series 312 box mounted seats. We are issuing this AD to prevent series 312 box mounted seats from detaching from the passenger compartment floor, which could result in injury to the occupant of the seat, and prevent evacuation of passengers in the event of an emergency.
