Diagnostic test

October 7, 2008 - 2:43pm

“Direct observation” of aviation employees during drug and alcohol tests applies only to individuals who are returning to duty after a previous positive test, or if there is reasonable suspicion. The tests apply to only Part 121 and 135 operations, although some Part 91 operators follow the regulations, according to Dr. Quay Snyder, president and CEO of Virtual Flight Surgeons, Aurora, Colo.
