Considering the report again, I guess the physical evidence at the crash site regarding the aileron cable disconnect may not have been sufficient for a criminal conviction......although possibly sufficient for a civil case.
I agree that it would be interesting to hear from a current Electra pilot......there are still around 20 Electras flying (I think nearly all in Canada in freight and fire fighting roles) so there must be a few on pprune.
There is an interesting diagram in the CAB report showing the crash site in relation to the runway....it appears the diameter of the turn the plane made was approx 5000ft. Someone with more expertise should be able to deduce average bank angle from this information.
Very best of luck in your search for further information.
