Rotax 503ULDCDI
71 aircraft on the U.S. register carry a Rotax 503ULDCDI engine, rated at about 52 horsepower. The Pipistrel TAURUS is the model most often fitted with it (5 aircraft). The aircraft carrying it were built between 1984 and 2023.
The FAA records engines by code, usually at the level of a series ("O-320 series") rather than the exact variant; this page gathers every FAA code that reads as Rotax 503ULDCDI. FAA spelling: 503ULDCDI.
