Continental A40 series

112 aircraft on the U.S. register carry a Continental A40 series engine, rated at about 40 horsepower. The Piper J-2 is the model most often fitted with it (34 aircraft). The aircraft carrying it were built between 1930 and 2002.

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 Continental A40 series. FAA spelling: A40 SERIES.
