Libert Ehram, 64, a Washington consultant who specialized in economic development and social programs and a former safety official of the old Civil Aeronautics Administration, died Thursday at the Washington Hospital Center after a heart attack.

Mr. Ehraman worked for Samuel Weiss Research Associates and was vice president of Stuart Rice Associates Inc. before he helped found the Surveys and Research Corp. here in 1958. He served as president of the firm from 1965 until its merger with Exotech Systems in 1971. He was president of Exotech until 1977, when he founded Era 2000 Inc., a Washington consulting firm, of which he was president at the time of his death.

He worked with federal agencies, such as the Agency for International Development, as well as foreign governments and national and international corporations and foundations on numerous economic development and antipoverty projects, particularly in the areas of commerce, transportation and agriculture.

He also worked with local antipoverty programs. He was president of the Southeast Community House for several years and founded its federal credit union. He received the United Planning Organization's community action volunteer service award for his "service and dedication to area anti-poverty programs."

A pilot and former air traffic controller, Mr. Ehram served with the Army Air Force during World War ii. He later instructed military personnel in air traffic control procedures.

From 1945 to 1957, he was a safety analyst and chief of safety analysis for the old Civil Aeronautics Administration.

Mr. Ehraman was born in New York City and graduated from the College of the City of New York. He did post-graduate work in economics at American University.

He lived in Washington and belonged to numerous professional associations, including the American Association for the Advancement of Science, the American Statistical Association, the American Sociology Association and the Institute of Management Sciences.

Survivors include his wife, the former Catherine R. James, of Washington; three sons, David J., of Denver, Daniel J., of Morgantown, W. Va., and Michael J., of Battle Creek, Mich., and a sister, Irma Gray of San Antonio, Tex.

The family suggests that expressions of sympathy be in the form of contributions to the American Heart Association.
