Flight Standards has reached its hiring goal for FY 2020. Tentative Offers do not expire, however the drug test is only good for six months and there is a limit to the duration of a security clearance. Also, if you were covered by the pre-employment memo (meaning you have an acceptable industry check) the check may expire. Leadership is evaluating their needs for the rest of the FY, and will onboard employees looking at the overall health of the Service. There are administrative needs, and some inspector needs, particularly in hard to fill locations. Most likely, any inspector candidate with a TOL will be onboarded, but only after October 1. As it says it the TOL, don't quit your job or sell your house.
