intended to minimise the possibility of dirt or mud penetrating the cockpit during an overturn skid and causing pilot asphyxia or injury.

             Since the original issue of this Airworthiness Directive, there have been reports of the bolts that attach the forward end of the original design overturn skid plate breaking in an overturn accident.  This allowed the skid plate to rotate around the rear attach point and the forward end of the plate to enter the cockpit area.

             Amendment 1 was issued in order to prevent the front and rear connections of the overturn skid plate to the airframe from breaking.

             Amendment 2 is issued in response to a new FAA AD, which retains the current actions required by this Directive but adds the requirement to modify the overturn skid plate installed Model AT-401B aircraft.
