What type of aircraft certification is available in the USA for the An-2?
The An-2 can only be certified as an Experimental-Exhibition, Experimental-Research, or (possibly, but not accomplished yet) as a Restricted-Agricultural (crop duster) aircraft. Current FAA policy (apparantly at the direction of the state department) is that this fine aircraft will never be allowed to be certified in any way in which it can be used for commercial purposes in the USA involving passengers, cargo, or parachute jumping. As best we can understand, this policy is designed to protect Cessna, Piper, and Beech from market loss and applies to other Soviet designed aircraft as well. Some FAA inspectors will tell you that it is because the aircraft was never approved under FAR-23 procedures since it was designed prior to normalization of relations between the USA and former communist countries. However, close inspection of other FARs (part-21) reveals that such aircraft could be certified in the USA after passing a conformity check, which the FAA is not presently allowing for An-2
