Airworthiness Directives; Raytheon Aircraft Corporation Model Beech 2000 Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Corporation (Raytheon) Model Beech 2000 airplanes. This AD requires immediately incorporating temporary revisions to the Limitations Section of the Airplane Flight Manual (AFM) that include requirements of not allowing flap operation during takeoff, accomplishing the preflight visual checks (referred to as visual inspections in the AFM temporary revisions) of the aft cove panel of the wing for delamination prior to each flight, and incorporating a repair scheme if delamination is found. This AD also requires repetitively inspecting the trailing edge of the wing by looking for delamination (debonding) (also referred to as cracks in the service information) through the thickness of the trailing edge of the wing cove skin panels, and modifying the center flap track rib attachment when delamination (debonding) is found. This AD is the result of a report of the wing cove skin panel separating from the wing while in flight on one of the affected airplanes. The actions specified by this AD are intended to detect and correct delamination of the wing cove skin in the area of the support rib, which could result in the delamination propagating to the trailing edge of the wing with the wing cove skin panel possibly separating from the wing.
