The other issue that stands out to me is that F30 was called for (not moved) and the condition levers placed into FTR but then F30 was stated as in position. This is unlikely to occur in the time line stated. As soon as the CLs got to feather the ACW goes off line, some residual hydraulic pressure may remain to drive the flaps to 30 but not likely. Also as soon as ACW goes off line you know about it. It's an electrical aircraft.
The last sentence of paragraph 1.1.5 states that a click was recorded and a flap 'surface' movement to 30 degrees was recorded. At that time, the props were still feathered. For someone not familiar with the type (or turboprops), what power would have been available to drive the flaps to 30 degrees at that time?
