UL,
I think you'll find that the reason the 139 in the aero hangar is not flying is because the NCAA are insisting on a tech rep for it. If aero have the contract to operate and maintain it for the government, they should have checked this with the NCAA beforehand. Naturally, it could be that after having all the necessary approvals the old BE (brown envelope) was not forthcoming (now that CHC and Bristow are super 'ethical'), so the goalposts were moved. The only company which approves of BEs now is possibly Caverton as they are not bound by American business principles.
