When I said PVD,I also meant to include IAHL/Integrity Aircraft. However,I do not beleive IAHL is an actual company with employees. To the best of my knowledge there is no IAHL office any where on this planet that some one could go to and speak to PVD or any technical personell. I think that it is all PVD. However to be totally accurate, neither PVD, Lance Watson, Integrity Aircraft, nor IAHL own the Intellectual Property of the BN Trislander.
