EDGEWOOD, Pa. (AP) _ Ethel Dwyer McCrady, who starred as Jane Porter in an elaborate Broadway production of ''Tarzan and the Apes'' in 1921, has died at the age of 86.

Mrs. McCrady, who died of a heart attack Monday at her suburban Pittsburgh home, retired from acting in 1924.

Among her mementos from the Tarzan show was a picture of Jim the Lion, who got loose backstage during a matinee and hastened the early close of the show with his royal roars, heard in nearby Broadway houses. The play closed after 14 performances at the Broadhurst Theater.

Born Ethel Selina Dwyer on May 30, 1899, in Tarrytown, N.Y., she began her stage career with a part in the chorus of ''Fiddlers Three.'' After Tarzan, she had a role in ''Lombardi Limited,'' which starred Leo Carrillo.

She made several silent movies but it was as the lead in ''Abie's Irish Rose'' that she toured Pittsburgh in 1923. On Valentine's Day 1924, she married lawyer Roland A. McCrady, and retired from acting.

She is survived by two children, Janice McCrady Forbes and Allen D. McCrady, six grandchildren and a great-grandson. Services will be private.
