From someone who is supposed to be good with numbers, this was a bit of an over statement from the great LT
MD produced 12 helicopters in 2010, not 50 | Helihub - the Helicopter Industry Data Source
Helihub quote; So, where does this leave us? HeliHub.com believes the 2010 production of MD Helicopters was 12 airframes - those listed in section 1 above.
Due to the (lack of) speed with which FAA keeps its data current, it is possible that the 10 airframes in section 2 were also 2010 production, but as all of these are still registered to MD Helicopters and not customers, we feel safe to assume that they were not. We are very open to the fact that there may be other information not available to us which could alter these figures. We will happily run another article in the future if MD Helicopters come to us with different figures substantiated by serial numbers and customer names in the way we have in this article.
