Lies, damned lies, and statistics !!!
First on the DA, I've double checked and there are two DA factories, one in Canada and one in Austria. There were three from each came into the UK - so as a company arguably they actually come in just above Cessna. A slight weakness in my analysis perhaps.
I don't think Eurocopter are delivering many singles.
The stats showed three Alpi Pioneers registered and built in 2004.
It's also possible that my stats missed aircraft registered in December that hadn't caught up into the database I was using.
Doesn't change the overall picture however.
