Federal regulations require carriers to test 25 percent of “safety sensitive” employees in a given year.
In 2015, more than 1,500 drug tests were verified positive out of more than 218,000 tests on safety sensitive employees, which include pilots, mechanics, flight instructors, flight attendants, aircraft dispatchers, ground security coordinators, non-TSA aviation screeners, and non-FAA/military air traffic controllers.
