Hi
js,
Just being curious, did you know the reason of your collective to yaw lockup after the loss your Hyd 2 system ? Hyd 1 wasn't powering the tail rotor servos anymore ?
..... and normally after landing, when pulling both engine levers back to idle, shouldn't you have yawed left instead of right ?
.... and in a situation of collective to yaw lockup, shouldn't an action on the left pedal, force your collective down instead of up ?
