Crab,
That was my point, the Wessex incident occurred after the simulated malfunction caused the disconnect coupling to engage from its incorrect position and the subsequent torque shock loading snapped a TR drive shaft leading to the loss of TR drive. I know it was unlikely to happen to me but the underlying cause, compacted grease within the coupling, had built over time and would have been present during my delivery flight.
I know the 169 has no disconnect coupling but as I said, looking at the video it looks like the incident began just after the application of pedal to kick the aircraft straight prior to transition. Coincidence? Probably but until the data recorder has been analysed we only have speculation so I try to keep mine to observable occurrences, I wish others could do the same to discourage some of the nonsense contained in this discussion.
