Baie-Comeau (Manic 1) Airport, identified by ICAO code CSL9, is a small general aviation facility located near Baie-Comeau in the Côte-Nord region of Quebec, Canada. It serves local and light aircraft operations in the area surrounding the Manicouagan River hydroelectric complex. The airport is distinct from the main Baie-Comeau Airport (ICAO: CYBC, IATA: YBC), which handles scheduled commercial passenger traffic. CSL9 functions primarily as a secondary or utility airstrip, supporting industrial, forestry, and private aviation needs in the region. Baie-Comeau itself is an important industrial city on the north shore of the St. Lawrence River, home to aluminum smelting and paper manufacturing operations, which drive demand for regional air access across multiple facilities.
