Dear Fellow Aviators. I have an interesting situation regarding the issuance of my 3rd class medical certificate. I am a Private Pilot who stated flying in 1987, shortly after I started flying I purchased an airplane and finished my training in that airplane. In 2003 I sold that airplane to persue another thing. In 2005 I was convicted of DUI=.0156. I paid my debt on that, paid the $, got the assessment, went to the classes and received my diving privileges back. In 2014, I purchased another airplane. I renewed my biannual training, disclosed the DUI, filed a pilots statement of alcohol use and passed my 3rd class exam, and received my 3rd class cert. Its been great up until recently, unfortunately. You see, earlier this year in April, a #2 pain started in my abdomen. After 5 days I was seen by a urgent care doctor, diagnosis GERT, prescribed over the counter Prilosec. Pain disappeared. I had also made appt. with GI doctor for follow up. I also made appt. with AME for this 2 year 3rd class med. cert.. I disclosed the incident to the AME, and passed the physical, except AME defered, until the results from the GI doctor. and sent all papers to the FAA along with the GI dr's report. Well after a very long wait, I finally received a certified letter from the FAA. Hurrah, just in time for Oshkosh. Not exactly. In it: #1 You will need to undergo an evaluation with a Human Intervention Motivation Study(HIMS). The HIMS AME should submit a narrative report summarizing the evaluation, which confirms that he has reviewed your FAA medical file, opines on your substance use history, and opines whether or not there appears to be an indication for a monitoring program. HIMS AME must comment on the 2005 DUI with BAC=.156, history of abdominal pain and notation of alcohol use in GI doctors narrative. GI doctors narrative stated patient drinks 2-3 beers daily. Hey, what gives, what ever happened to 8 hours bottle to throttle.? What do you think?
