Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for certain Beechcraft Corporation (type certificate previously held by Hawker Beechcraft Corporation) Models 1900, 1900C, and 1900D airplanes. This AD was prompted by reports of cracking in the front spar cap angles and hat section structure of the vertical stabilizer. This AD requires inspections of the vertical stabilizer spar angles and hat section for cracks with corrective actions as necessary. We are issuing this AD to correct the unsafe condition on these products.
