This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 96-16-06, which was sent previously to all known U.S. owners and operators of certain Weatherly Aviation Company, Inc., (Weatherly) Models 620A and 620B airplanes. This AD requires inspecting all wing hinge pins, part number (P/N) 40852-001, at the main wing-to-center section attachment (four per airplane) for depth of the threaded ends, length of the pin, and position of the pin; and replacing or repositioning any pin, as necessary. A report received by the Federal Aviation Administration of manufacturing deficiencies at the area of the main wing center section attachment prompted the AD. The actions specified by this AD are intended to prevent failure of the wing hinge pin, which could result in the wing separating from the fuselage.
