I am a licensed commerical pilot who both flies for aliving and enjoys sport aviation.This final review should never have been published without a comment period prior to the final rule.  While this rule may have been developed with good intentions, its potential for abuse and lack of due process or appeal are serious oversights.  In adition, the lack of guidance as to what constitutes a security threat  leaves it up to individual persons to interpret and we all have experience with where that can lead.  This rule needs to be reviewed by the normal NPRM  process and a new final rule developed based on those inputs.  Thank you
