It describes how engine parameters, flight data, CETADS, and ITADS support propulsion system management and engine health monitoring. It requires designated personnel to manage the program, review engine performance, process data, and coordinate maintenance actions.
The Engine Trending & Diagnostic (ET&D) program is intended to further the safe operation, performance reliability, and lower maintenance operating costs of installed gas turbine engines. (paragraph 1)
The program analyzes trends in all available engine parameters to detect the onset of engine internal failures and shifts in instrumentation calibration or accuracy. (paragraph 1)
Ensure the primary and alternate ET&D Project NCOs receives the ET&D training course within 6 months of assignment of duty or at the earliest opportunity. (paragraph 4)
Ensure ET&D computers obtained from OC-ALC are not modified or used for non-ET&D applications to include and not limited to Integrated Maintenance Data System (IMDS), E-mail, Internet and Intranet. (paragraph 4)
Ensure engine flight data is downloaded following the daily flying period, entered into the Comprehensive Engine Trending and Diagnostic System (CETADS) database and forwarded to the Engine Management Element (EME) no later than 0700 the next duty day. (paragraph 4)
