CAPE CANAVERAL, JAN. 5 -- An internal report written last year cited major deficiencies in NASA's shuttle safety program, including an alarming "business-as-usual" attitude, but agency officials insisted today that the shortcomings have been corrected.

The report, submitted to the National Aeronautics and Space Administration last August, was written by the eight-member Space Transportation System Safety Risk Assessment Ad Hoc Committee based on information gathered between November 1986 and February 1987.

"The concern for {shuttle} safety, which peaked shortly after the Challenger accident, appears to be waning, and in many areas this has been translated by workers, engineers and supervisors to a 'business-as-usual' attitude," the panel said.

"There are disturbing signs that some of the pre-Challenger safety-related problems which were identified in the aftermath of the accident still exist."

Responding to the publication of excerpts from the report in The Atlanta Constitution, NASA said nearly all of the shortcomings cited have been corrected.

"NASA has directly addressed all of the specific safety issues recounted in the report," a statement said. "Nearly all recommendations were either implemented while the report was being prepared or have since been implemented."

The statement said that NASA has set "extremely high safety standards" and that the agency has made "safety its top priority." The panel's report acknowledged at the time that many of the deficiencies cited were being corrected.
