William V. Gough, 64, a retired official of the Federal Aviation Administration and a former test pilot, died of cancer April 21 at Alexandria Hospital. He lived in Alexandria.

Mr. Gough, who was born in Baltimore, graduated from Johns Hopkins University in 1938 and was commissioned in the Navy, where he became a pilot. During World War II, he won a Silver Star from the Army for flying nurses and other personnel out of the Philippines before the Japanese quelled all resistance there. He retired from the Naval Reserves with the rank of captain.

After the war, Mr. Gough became a civilian test pilot at the Lewis Flight Research Center in Cleveland, now a facility of the National Aeronautics and Space Administration.

In 1962, he moved here and joined the FAA, where he worked in the office of research and development. He retired in 1973 and became a private consultant.

He also was a chairman of disaster services in the Alexandria chapter of the Red Cross, a past president of the Robert E. Lee Chapter of the Reserve Officers Association and the Animal Welfare League of Alexandria and a Boy Scout master.

Survivors include his wife, Mary Louise, of Alexandria; a son, George, of Stockholm; three sisters, Esther Redman of Leonardtown, Md., and Ruth Dummer and Miriam Wingate, both of Baltimore; a brother, Melvin, of Melbourne, Fla., and two grandchildren.
