Airworthiness Directives; Frakes Aviation (Gulfstream American) Model G-73 (Mallard) Series Airplanes and Model G-73 Airplanes That Have Been Converted To Have Turbine Engines

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2006-01-51 that was sent previously by individual notices to all known U.S. owners and operators of Frakes Aviation (Gulfstream American) Model G-73 (Mallard) series airplanes and Model G-73 airplanes that have been converted to have turbine engines. This AD requires an inspection to detect repairs, cracking, or corrosion of the wings from wing station (WS) 77L to WS 77R, front spar to rear (main) spar; removal of repairs, if found; removal of sealant from the interior of the wet bays; and repair of any crack or corrosion. This AD results from a report indicating that the right wing of a Frakes Aviation (Gulfstream American) Model G-73 (Mallard) airplane separated from the fuselage on takeoff, which resulted in the airplane impacting the water near Miami Beach, Florida. We are issuing this AD to prevent structural failure of the wing and loss of control of the airplane.
