## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Cessna Model 750 airplanes, that requires removal of a certain existing bulkhead web doubler, installation of left and right bulkhead web doublers, and enlargement of the lightening holes. This action is necessary to prevent jamming of the roll control system, due to inadequate clearance between the control cable and the web, which could result in reduced controllability of the airplane.
