Operational Loads Monitoring of a Fleet of Beech 1900D Aircraft

Presented here are analyses and statistical summaries of data collected from 11,299 flight operations recorded on 6 BE-1900D aircraft during routine commuter service over a period of three years. Basic flight parameters such as airspeed, altitude, flight duration, etc. are shown in a form that allows easy comparison with the manufacturer's design criteria. Lateral ground loads are presented for ground operations. Primary emphasis is placed on aircraft usage and flight loads. Maneuver and gust loads are presented for different flight phases and for different altitude bands. In addition, derived gust velocities and various coincident flight events are shown and compared with published operational limits. The data presented in this form should allow an objective comparison of the existing certification and design criteria with actual usage data, thereby affording aircraft manufacturer and operators a better understanding and control of those factors that influence the structural integrity of commuter aircraft.
