I have a friend that broke his leg. A year after the Dr said he was
100% back to normal, the FAA finally agreed to do a SODA ride with him
(they wanted to just deny the medical). It was a pretty easy ride since
he didn't have any change in use of the leg, but this is the FAA. The
FSDO handed him a "temporary" medical that allowed him to take the ride
since the pilot examiner isn't PIC. After only another 6 months, a real
class III showed up without restriction.
