James David McNutt, 53, a flight crew scheduler with United Airlines and a coach of children's baseball teams, died of cancer Friday at Fairfax Hospital.

Mr. McNutt worked for United Airlines for 30 years. He also was a partime real estate salesman. He was a former member of the Capitol Airlines softball tean and a past president of its Fleet Club.

A native of Lynchburg, Va., he was a member of the varsity football team of his high school there. He attended Benjamin Franklin University and the Computer Institute in Washington.

Mr. McNutt, who had lived in Springfield, coached Babe Ruth and Little League baseball teams and was active in the Lynbrook Elementary School PTA. He also was active in civic associations in the Springfield area and was a member of the Springfield post of the American Legion.

Mr. McNutt served in the Marine Corps during the Korean War.

His marriage to the former Patricia O'Brien ended in divorce.

Survivors include a son, James D. Jr., of Annandale; a daughter, Cheryl Ann, of Alexandria, and his mother, Iva. W. McNutt, and a sister, Ethel M. Jollensten, both of Odenton, Md.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
