Air Tractor, Inc. AT-200, AT-300, AT-400, AT-500, AT-600, and AT-800 Series Airplanes
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.

Boeing Model 747-400, 747-400D, and 747-400F Series Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to all Boeing Model 747-400, 747-400D, and 747-400F series airplanes. That AD currently requires reviewing airplane maintenance records, doing repetitive inspections for cracking of the yaw damper actuator portion of the upper and lower rudder power control modules (PCMs), replacing the PCMs if necessary, and reporting all airplane maintenance records review and inspection results to the manufacturer. This new AD limits the applicability, reduces the initial inspection threshold and repetitive interval, removes the reporting requirement, and requires installation of a secondary retention device for the yaw damper modulating piston. Installation of the secondary retention device terminates the repetitive inspection requirements. This AD results from additional reports of failure or cracking of the PCM manifold in the area of the yaw damper cavity endcap at intervals well below the initial inspection threshold of the existing AD. We are issuing this AD to prevent an uncommanded left rudder hardover in the event of cracking in the yaw damper actuator portion of the upper or lower rudder PCMs, and subsequent failure of the PCM manifold, which could result in increased pilot workload, and possible runway departure upon landing.
