| The base where it has broken is the part which of the tail boom which would be under the most load whilst flying, as torque= force x distance. If the boom was going to crack due to the force of the tail rotor, that's where it would crack. Perhaps a hairline fracture in the boom before you took off, which then cracked rapidly under load?
Wouldn't a out of balance tail generate a forward/aft cyclic type vibration? In the photos, it looks like the boom has cracked sideways. It looks as if it has cracked from the left side of the boom first, then the last bit of carbon has peeled, and finally given in. Looking again, it has cracked paralell to one weave, then parallel to the other once it has peeled... |
