Wright TC18DA series

3 aircraft on the U.S. register carry a Wright TC18DA series engine, rated at about 3250 horsepower. The Douglas DC-7 is the model most often fitted with it (2 aircraft). The aircraft carrying it were built between 1945 and 1958.

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 Wright TC18DA series. FAA spelling: TC18DA SERIES.
