Cracks in the tail boom seem to come to mind with the strakes fitted
Not just with strakes, which I know nothing about. 205/212 tailbooms were always in the shop being reskinned, and I don't mean that to be an archilles heel in the helo, just a reflection of the stress the boom is subject to. Could always build it out of boiler plate I guess, but the CofG may be a bit out of whack.
