Providing an automated data collection system together with a regulatory flight recorder function, the Engine Performance Trend Monitor / Structural Integrity (EPTM/SI) System reduces flight crew workload and improves accuracy of collected data by using a lightweight, compact, survivable recording system. This combination system automatically monitors flight loads and aircraft usage for transfer to an Aircraft Structural Integrity (ASIP) program, and records engine trend data for input to engine trend monitoring software while maintaining a record of the last eight hours of flight data. The purpose of this paper is to describe the system components, capabilities, and growth options.
