Airworthiness Directives; Boeing Model 757-200PF Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 757-200PF series airplanes, that requires revising the Airplane Weight & Balance (W&B) Manual to prohibit operation of any airplane without side vertical restraints installed on the main cargo deck when carrying a particular pallet. This amendment also provides for optional terminating action for the Airplane W&B Manual revision. This amendment is prompted by reports indicating that some airplanes have been operated without side vertical restraints installed on the main cargo deck when carrying certain pallets. The actions specified by this AD are intended to prevent inadvertent movement of a cargo pallet during flight, which could result in an adverse center of gravity condition and consequent reduced controllability of the airplane.
