Bernam River Airfield (BRA) is the first private airpark in the country. The airport which covers an area of 221 acres (89 ha), was built to provide infrastructure for the general aviation (GA) industry in Malaysia. The recent increase in air traffic at the Subang Airport and the imminent closure of the Sungei Besi Air Base (WMKF) has accelerated the need for an alternative site for light aircraft to operate.
The property is located in Mukim Hulu Selangor adjacent to the Perak state border, between Behrang and Slim River. It is relatively near to the North-South Expressway, approximately 90 km driving distance and 40 nautical miles (74 km; 46 mi) (about 35 minutes flying time) from Subang Airport.
