The scope of activities performed involved the following: (1) design, development, manufacturing and test of a low-cost Airframe Cumulative Fatigue System (ACFS), (2) installation of the ACFS into a fleet of seven Cessna 172 aircraft owned and operated by Embry-Riddle Aeronautical University, (3) conduct aircraft usage data acquisition on seven Cessna 172 aircraft, (4) define the effectiveness of ACFS in the data acquisition effort and any required design changes required for the ACFS, and (5) provide the resultant processed data from the data acquisition effort in formats useful to the FAA. Presented in this report are the description of the ACFS, the analysis and statistical summaries of the data collected from lOC flights representing 1168 hours of Cessna 172 aircraft operational data. The end product from the data acquisition effort includes statistical information on acceleration, speeds, altitudes, and flight duration and distance. 收起
