On September 1, 1962, the Navy decommissioned NAAS Brown Field again and transferred ownership of Brown Field to the City of San Diego with the condition that it remain a public airport. During the mid to late 1960s, Pacific Southwest Airlines, an airline based in San Diego, trained its pilots at Brown Field using Piper Arrows, Comanches, Aztecs, and Beechcraft Bonanzas. PSA also had a contract to train Lufthansa pilots at Brown Field. In 1970, Lufthansa training moved to Phoenix, Arizona, where it remains today.
