Commissioned that September as a first lieutenant in the Officers Reserve Corps with a pilot's aeronautical rating. Lieutenant Patterson was assigned to the 137th Aero Squadron as a test pilot at Wright Field the in May 1918. On June 19, 1918, Lt. Patterson and his observer, Lt. LeRoy Amos Swan, went on a flight to test newly installed machine guns synchronizers on a DH-4. They completed two trials successfully, but during a steep dive on the third test the airplane's wings collapsed and the aircraft crashed, killing both crewmen.
Citizens of the Dayton, Ohio believed that part of the local air base should honor the Patterson family for their leadership in keeping the engineering center in Dayton. On July 1, 1931, a portion of Wright Field eastt of Huffman Dam was redesignated "Patterson Field" in honor of Lt. Frank Stuart Patterson. The facility was later designated as Wright-Patterson Air Force Base.
