More than 615 comments–the great majority negative–were submitted on rules adopted in January that permit the FAA to immediately suspend or revoke the airman certificate of any pilot or mechanic the Transportation Security Administration has “determined to pose a security threat.” The rules establish procedures to appeal the action to the TSA; however, they cannot be appealed to a third party such as the NTSB. Also, pilots would not be shown the “evidence” against them.
