Veterans Affairs investigators discovered the inconsistencies more than two years ago by cross-checking federal databases, but the FAA has kept many details of the case a secret from the public.
FAA spokesman Matthew Lehner acknowledged in a statement that the agency has been investigating about 4,800 pilots “who might have submitted incorrect or false information as part of their medical applications.” The FAA has now closed about half of those cases, he said, and has ordered about 60 pilots — who Lehner said “posed a clear danger to aviation safety” — to cease flying on an emergency basis while their records are reviewed.
About 600 of the pilots under investigation are licensed to fly for passenger airlines, according to a senior U.S. official familiar with the matter who spoke on the condition of anonymity to discuss an ongoing case. Most of the rest hold commercial licenses that allow them to fly for hire, including with cargo firms, corporate clients or tour companies
