So the S-76D received type certification 12th October 2012 and at that time Sikorsky stated in their press release that they would "begin deliveries later this quarter".
Eight months on and still no deliveries is kind of strange unless you have a major problem. Some rumours seem to point to the structure down the back end being the problem. Anybody able to confirm if this is correct and if so what is the problem and what is the fix?
