Just joined so someone may have covered this, then sorry.
The first event is the left engine bleed going closed coincident with left Objective torque increase, followed by the right prop starting to change pitch and prpm followed by the right engine Master warning then the right engine parameters start to wind down.
Have flown several TP but not familiar with the ATR so maybe an ATR type can explain that?
And another thing, I thought we had got over ATC giving you frequency changes while your ass is on fire
