According to this article http://pilots-airmen.findthedata.org/l/1114801/Chapo it is clear that Roni Chapo's pilot medical exam expired one and a half years ago.
What exactly does this mean?
In order to keep everyone safe, the FAA requires a pilot medical certificate from an FAA medical examiner prior to flying solo or earning a pilot certificate. Pilot medical requirements vary depending on what kind of pilot you are.
Who needs a medical certificate?
First, balloon pilots and glider pilots (and students seeking a pilot certificate in a balloon or glider) do not need to have an aviation medical exam done. But Chapo claims to be a pilot holding ratings numbers 1 (airplane single engine land) and 2 (airplane multiengine land) both of which require a current medical license.
Additionally he is licensed only in the EU region as the report shows. [continued below]....
If pilot's clearly do not meet FAA medical standards, particularly if they have conditions that are specifically grounding in Part 67 of the FARs or the Guide to Aviation Medical Examiners, the aviation medical examiner may issue a denial letter to the pilot revoking the pilot's current medical privileges. That information is forwarded to the FAA Aeromedical Certification Division which will then issue a formal denial letter and request return of the current Airman's Medical Certificate.
So how does he put up a website and run a flight school without the intervention of the local authorities?
And while this report http://pilots-airmen.findthedata.org/q/1114801/2121/Where-is-the-pilot-Roni-Chapo-located - shows him located in the city of Ramat Gan - the business address of his "school" is the city of Rishon Lezion - several miles away.
