Summary
We propose to supersede Airworthiness Directive (AD) 2018-11- 07, which applies to all Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. AD 2018-11-07 requires 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. Since we issued AD 2018-11-07, we have determined that it is necessary to require the terminating action. This proposed AD would retain the actions of AD 2018-11-07 and require the terminating action for the repetitive inspections. We are proposing this AD to address the unsafe condition on these products.
