Airworthiness Directives; Raytheon Aircraft Corporation (Formerly Beech Aircraft Corporation) 35 Series Airplanes

摘要

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Raytheon Aircraft Corporation (Raytheon) 35 series airplanes. The proposed action would require inspecting the ruddervator differential tail control rod assembly for corrosion or cracks, repairing or replacing any cracked or corroded part, and applying anti-corrosion sealant to the ruddervator control pushrods. The proposed action results from a split in the ruddervator control push rod on an affected airplane that was found during a routine inspection. The split occurred when water froze in the internal area of the control push rod and then expanded. The actions specified by the proposed AD are intended to prevent failure of the differential tail control rod assembly, which could result in loss of control of the airplane.
