Mmmm ...
....
could never understand how those oversized vertical tail stabilizers did not snap tails off on the earlier 117's and the ec145 ....... In fact I heard a rumour that a 117 stateside did loose its tail some years back for that reason.? ......
Bolkow .... if by the above you mean the NewYork 'Colgate' machine you need to research that incident ...you will find it had nothing to do with the vertical stabilisers and a lot to do with an improper repair to taliboom vertical spar cracks.
