Bell 412 NR
Well, my dears, I wasn't going to waste more time wading through 4 years of correspondance to find the actual letter from Bell, - but if you choose not to believe me (despite the halo) and are SO durned desperate for written proof, why don't you just drop Bell Customer Support a line yourselves - or don't you guys talk to them at all?
Unless you are based in Iran, Bell will probably respond and may even satisfy your every need (within the constraints of product liability legalities)!!! If you are, then best not to email or call them at all - you might find some GPS targeted munitions from GWB incoming onto your bonce!
Seek and ye shall find, Glasshopper!
