You can fight a Form 8 all you want, however read 11-202V2 where it says it's the examiner's judgement. It's not going to get removed. Buddy of mine taught in the -135 FTU with me (Boom) and was refueling the C-17 FTU Sq/CC years ago when he crushed the ice shield, then my buddy called a breakaway. My Sq/CC at the time said he's Q-3'ing my buddy, however if the safety report comes back and exonerates him, he'd remove the Form 8 from his FEF. The safety report came back stating that the reason for the crushed ice shield was 100% the C-17 FTU Sq/CC's fault, which he openly admitted to. However when my Sq/CC went to take it out of my buddy's FEF the OG/CC, who's a piece of shit, told my Sq/CC if he removed the Form 8 from his FEF, he would put one in his FEF with the OG's signature on it. So my buddy has a Q-3 for something that a safety report said he wasn't the cause of.
In the end after being an evaluator for 10-years I can tell you that unless you caused a Class A mishap, or you almost killed people, it's going to take more than one Form 8 to send you to an FEB. If people got FEB'd based on fucking up aircraft flying there wouldn't be one Boom Operator in the USAF.
