Matt, this is one of those situations where "holding out" on a web board conflicts with what I know to be the best thing to do. I should have just told you to hire me.
Records for seven years are obtainaible in most states from the hospitals. It's cost is $40-50 each hospital. They use outside data services to produce the records.
Then go to you rehab or primary care guy and have the doc write a whole page letter, describing what happened, your hospital / operation course, (You'll have all the op notes and discharges summaries, for heaven's sake), and then summarizing your current performance, and any driver's license qualification stuff you've been through.
See, these guys are occupational medicine /regulatory specialists, not patient-care docs. It's a different world view. In this situation I have filmed the cnadidate in the aircraft as sole manipulator of the controls. That has helped the examiners.
THEN you have to get an AME to issue you a certificate with the limitation "Valid for flight test only" so you can take the FSDO ride.
The referral process takes six to eight weeks, I got one done for a part 91 corporate airman, in three weeks, but that's because we went to the TOP, AND the local FSDO guy Warren S--th is well known to us as a reasonable guy for these matters.
