Airworthiness Directives; Raytheon Aircraft Company Models 1900, 1900C, and 1900D Airplanes

Zusammenfassung

This amendment revises Airworthiness Directive (AD) 97-15-13, which currently requires installing lubrication fittings in the airstair door handle and latch housing mechanisms on certain Raytheon Aircraft Company (Raytheon) Models 1900, 1900C, and 1900D airplanes (formerly referred to as Beech Models 1900, 1900C, and 1900D airplanes). Certain Model 1900C serial number airplanes were incorrectly referenced as Model 1900D airplanes in the Applicability section of AD 97-15-13. This AD maintains the requirements of AD 97-15- 13, and corrects the model and serial number reference as described above. The actions specified by this AD are intended to prevent moisture from accumulating and freezing in the airstair door handle and latch housing, which could result in the door freezing shut and passengers not being able to evacuate the airplane in an emergency situation.
