This AD was prompted by a report indicating that some screws that attach the passenger seat tracks were undertorqued. We are issuing this AD to prevent improper torque of those screws, which in the case of a hard landing or a high deceleration impact condition could result in damage to the seat and possible subsequent injury to the passenger.
