Diepkloof Airfield (ICAO: FANX) is a small general aviation facility located near Malmesbury in the Western Cape province of South Africa. It serves private pilots, agricultural aviation, and light aircraft operations in the surrounding Swartland agricultural district. The airfield is not served by scheduled commercial airline services and functions primarily as a utility field for the local farming community and private flyers. It lacks the infrastructure of a commercial airport, operating instead as a basic landing strip.
