I have just been told about the image as on Willpete's post. It is interesting as a follow up to the OZ M/R blade crack incident. The blade on the right hand side does appear to have a crack of the same dimension, shape and near enough to the same position as the OZ one. A crack happening in flight as it did over here, will give increasing vibrations. There is possibly good reason to assume those vibrations intensified quickly enough to then snap the other blade off. and bend the cracked blade, I believe that almost immediately the broken blade departed M/R rotation would have ceased..It would be interesting to hear the TSN of the blades and can it be confirmed they are the latest blades?.. T/R drive continuance for at least a second could certainly have initiated cabin spinning. Cab damage looks merely due to water contact. tet.
