The FAA is adopting a new Airworthiness Directive–2012-CE-026-AD–for 35 Hawker Beechcraft C90GTi King Air twin turboprops. This AD was prompted by reports of incorrect gauge wires used in certain wiring bundles for the cockpit electrical power for backlighting and instrument panel components. This AD requires replacing the incorrect wiring bundles, inspecting associated wiring bundles and components for heat damage, and taking all necessary corrective actions. The new AD becomes effective Nov. 27, 2012.
