**Background**
The FAA Engine and Propeller Directorate (EPD) issued the original policy on time limited dispatch (TLD) on October 28, 1993. The purpose of that policy is to assure uniformity in applying TLD to engines fitted with FADEC systems. In this revision, the FAA recommends that an applicant for engine type design approval include appropriate TLD information in the engine installation manual. This revised policy does not create any new requirements.
