AD FAA-2013-0611

We are superseding Airworthiness Directive (AD) 2011-27-51 for certain Beechcraft Corporation Models 1900, 1900C, and 1900D airplanes. AD 2011-27-51 required inspecting the elevator bob-weight and attaching linkage for correct installation and for damage or deformation to the weight and/or weight bracket with corrective action as necessary. This AD requires installation of the secondary elevator bob-weight stop bolt. The elevator bob-weight (stabilizer weight) traveling past its stop bolt may allow the attaching linkage to move over-center and lead to reduced nose down elevator control. We are issuing this AD to correct the unsafe condition on these products.
