Leblond 85 series

10 aircraft on the U.S. register carry a Leblond 85 series engine, rated at about 85 horsepower. The Rearwin 8500 is the model most often fitted with it (4 aircraft). The aircraft carrying it were built between 1936 and 1954.

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 Leblond 85 series. FAA spelling: 85 SERIES.
