WASHINGTON — A congressional investigation raised new concerns today about the nation's air traffic control system, concluding there are too few experienced workers to handle a steadily increasing flow of air travel.
An unreleased report by the General Accounting Office, an investigative arm of Congress, was based on an extensive survey of the controller work force and found that workers' morale and fatigue remain a problem 4 1/2 years after President Reagan fired 11,400 controllers for striking illegally.
Rep. Guy V. Molinari (R-N.Y.), a critic of the Federal Aviation Administration, said the study is "a serious indictment of the air traffic control system. . . . I have concluded that the system is not safe."
During the last few months, congressional investigators sent questionnaires to 4,500 radar-qualified controllers and 1,000 supervisors. About 75% responded to the survey.
