## Summary

We propose to supersede airworthiness directive (AD) 2011-27- 51 that applies to certain Beechcraft Corporation Models 1900, 1900C, and 1900D airplanes. AD 2011-27-51 currently requires 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. Since we issued AD 2011-27-51, a secondary elevator bob-weight stop bolt has been designed. This proposed AD would require 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, which could result in loss of control. We are proposing this AD to correct the unsafe condition on these products.
