Airworthiness Directives; Saab AB, Saab Aeronautics (Formerly Known as Saab AB, Saab Aerosystems) Airplanes

概要

We are superseding Airworthiness Directive (AD) 2018-11-07, which applied to all Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. AD 2018-11-07 required a one-time inspection of an affected lug attaching the aileron bellcrank support bracket to the rear spar of the wing and the adjacent area of the installed support brackets, a thickness measurement of the affected lug, repetitive inspections of the affected aileron bellcrank support brackets, and corrective actions if necessary. AD 2018-11-07 also provided an optional terminating action for the repetitive inspections. This AD retains the actions of AD 2018-11-07 and requires the terminating action for the repetitive inspections. This AD was prompted by a determination that it is necessary to require the terminating action. We are issuing this AD to address the unsafe condition on these products.
