Andrew sent this for . . I should have all this right . . Reinstatement ( or reappointment ) is the reemployment of an individual , under internal assignment ( o r merit promotion ) procedures , to a FAA position based on their previous status as an employee with a federal or quasi-federal agency . Three categories of individuals have reinstatement eligibility without time limitation . They are : ( 1 ) former permanent FAA employees who completed a one year probationary period ; ( 2 ) former competitive career or career - conditional employees who completed a one year probationary period ; and ( 3 ) former excepted service employees who completed a one year probationary/trial period . Documentation Required : The documentation required ; i.e. , the job application package , must contain : Resume or written work history ; Copies of all certifications Standard Form ( SF ) -50 , Notification of Personnel Action , verifying an original appointment SF -50 verifying the completion of a one - year probationary/trial period ; and SF -50 documenting the candidate 's separation from the FAA . So that HR can make a qualification determination , etc. the manager/supervisor would obtain a detailed resume , certifications , SF -50 , ( and DD -214 ) if applicable from the person
