Probably a reason there aren't too many ASRs on this could be the fact that THEY will want you to come in a discuss it with the committee or doctor or whomever. After doing one of these trips, who wants to then head to clinic on one's day off to discuss this absurdity?
Look they want you to file an ASR for everything (ref. how many incidences are required to be filed). Look at the ridiculous ASR filled on the weekly safey report-all to cover one's backside. Why are we not seeing more IAH fatigue related ASRs?
