Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Boeing Model 757-200PF series airplanes. This proposal would require 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 proposal also would provide for optional terminating action for the Airplane W&B Manual revision. This proposal 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 the proposed 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.
