Airworthiness Directives; Fairchild Aircraft SA226 and SA227 Series Airplanes

Краткое содержание

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Fairchild Aircraft SA226 and SA227 series airplanes. The proposed action would require installing foreign object damage (FOD) barriers in the floorboards of the cockpit between the pedestal and floor from Fuselage Station (FS) 79.38 to FS 88.06 and on the outboard forward edge of the left-hand and right-hand cockpit forward floorboards at FS 79.38. Two incidents of objects falling through openings of the cockpit floor and jamming the elevator controls and the yoke prompted the proposed action. The actions specified by the proposed AD are intended to prevent airplane flight control jammings caused by objects falling through the cockpit floor openings.
