Full official abstract
We are adopting a new airworthiness directive (AD) to supersede AD 2002-25-09, which applies to certain Air Tractor, Inc. (Air Tractor) AT-250, AT-300, AT-400, and AT-500 series airplanes. AD 2002-25-09 currently requires you to install an overturn skid plate in the cockpit area. Since we issued AD 2002-25-09, we received a report of the bolts attaching the forward end of the original design overturn skid plate to the airframe 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. Consequently, this AD would require the installation of a modified skid plate kit or modification to skid plate kits that are already installed, including those already installed on AT-402B, AT-502B, AT-602, and AT-802A series airplanes during production. We are issuing this AD to prevent the front and rear connections of the overturn skid plate to the airplane from breaking, which could allow foreign debris to enter the cockpit during an airplane overturn. This condition, if not corrected, could lead to pilot injury.
