Rotax 505

5 aircraft on the U.S. register carry a Rotax 505 engine, rated at about 40 horsepower. The Glaser-Dirks DG-800 is the model most often fitted with it (2 aircraft). The aircraft carrying it were built between 1985 and 1994.

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 505. FAA spelling: 505.
