Kinner R5 series

156 aircraft on the U.S. register carry a Kinner R5 series engine, rated at about 160 horsepower. The Ryan Aeronautical ST3 is the model most often fitted with it (99 aircraft). The aircraft carrying it were built between 1929 and 1990.

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 Kinner R5 series. FAA spelling: R5 SERIES.
