Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to Beech Aircraft Corporation (Beech) Model 1900D airplanes. The proposed action would require inspecting the stabilon attachment angles for the correct thickness, repetitively inspecting for cracks in the attachment angles and replacing the attachment angles with ones of the correct thickness. Recent reports of installing the incorrect size of stabilon attachment angles on certain Beech 1900D airplanes prompted the proposed action. The actions specified by the proposed AD are intended to prevent separation of the stabilon from the airplane, which could cause loss of airplane stability during flight.
