Mee3, havent a clue what you are talking about, perhaps you could put in English so that I can understand what you are saying, but I really do understand business and manufacturing, go along with the OEM's if you wish .I have given you examples of how we are having the piss taken. As an owner / operator ie the person signing the cheques for these things, the industry is killing itself. Lets take MD helicopters, they took back the overhaul of transmissions , so they are now the sole agency allowed to do it, guess what price for an overhaul up from around $ 85k to close to $130k overnight, easy when you are a monopoly. Most of the so called R and D was paid for by various militaries normally the US mil eg, 206, 500, Allison 250, years ago. The RR 350 and 500 engines, lots of Rand D went into those, basically a 60 year old design tinkered with ! We really need to wake up and smell teh coffee before the industry totally emplodes.
