The General Accounting Office told Congress yesterday that a Carter administration decision to permit Concorde supersonic transport service to the United States "is counter to the thrust of the national noise abatement effort."
The GAO reached that conclusion, it said in a report to the House Government Operations Subcommittee on Environment, Energy and Natural Resources, because the plane does not meet present noise standards for slower-than-the speed-of-sound air-planes and cannot be modified to do so.
The report also attacked the Federal Aviation Administration's public opinion survey on Concorde operations. An FAA contractor interviewed residents living around Dulles International Airport before and after Concorde operations began there in May, 1976.
Those surveys, the GAO said, "will not provide reliable information on the public response to Concorde operations" because of "problems" in the survey's sampling plan, questionaire design and processing of questionaire responses.
The GAO report was released by subcommittee chairman Leo J. Ryan (D-Calif.), who has been leading the anti-Concorde fight in the House in recent weeks.
Ryan also released a letter he sent to Transportation Secretary Brock Adams, formally requesting the administration's secret "options paper" outlining possible Concorde decisions. Adams has offered to give Ryan a classified briefing on the paper, which Ryan has declined. If he accepts the briefing, he can't talk inpublic about the paper.
