Airworthiness Directives; Raytheon Aircraft Company Model 1900D Airplanes (formerly Beech Aircraft Corporation)

This amendment adopts a new airworthiness directive (AD) that applies to Raytheon Aircraft Company (Raytheon) Model 1900D airplanes (formerly referred to as Beech Aircraft Corporation Model 1900D). This action requires inspecting the stabilon attachment angles for the correct thickness, repetitively inspecting for cracks, and replacing the attachment angles that are the incorrect thickness with ones of the correct thickness. Recent reports of the affected airplanes having the incorrect size stabilon attachment angles prompted this action. The actions specified by this AD are intended to prevent separation of the stabilon from the airplane, which could cause loss of airplane stability during flight.
