I swear I heard somewhere that you can convert a Harvard with some mods (landing gear and the exhaust pipe, I recall) to register it as a T-6 and therefore not as an Experimental aircraft. Is that correct? Does it not apply to the Harvard IVs?
Also, why is an Experimental Harvard less desirable than , I assume, a Standard T-6? How does the registration effect day to day flying operations?
Harvard IVs were never type certificated when the T-6 series was (in the late 40's) because they hadn't been built yet. The Harvard IV's were built in '51 and '52 I think. Since they were built/assembled on foreign soil, they qualify the same way for airworthiness as would a Sea Fury for instance.
AFAIK, the Harvard II's were built in the US and can be certified in the Standard Category.
You can physically modify a Harvard IV into something looking like a T-6 (some parts and systems are in fact unique to the Harvard IV), but the fact remains that some of the parts were not built in the US (although most were) and captured by the original T-6 type certificate. Of course you could swap dataplates with a T-6 scrapped in days gone by- Banaire used to sell data plates with registration, but those were sold out years ago.
Experimental Exhibition is less desirable than Standard Category because you are subject to operating limitations when you get your airworthiness certificate. You can't give dual instruction like you can with your Cessna 150 for instance and you can't use your aircraft to commute.
With some of the changes going on with respect to Experimental Exhibition aircraft, you may be required to send the FAA a list of venues you will attend each year or may need to give 2 weeks notice prior to leaving your home airport for anything but a local recurrency flight. I'm not sure if any of this is still required though.
All this being said, the Harvard IV is the best of the T-6 series mechanically. They came with all the latest systems and structural mods and were not remanufactured from worn out trainiers. They typically have much less total time as well.
