mudflap

Mudflaps are fitted to types whose low-slung engines sit in the spray path of the nose wheel — the Boeing 737 and the Douglas DC-9 and MD-80 families are the familiar examples. It is a small detail and a reliable way to identify a variant, and the word is used as freely by engineers as by spotters.
