rolling out full left when engaging the reverse

[cmbaviator]

Hi,

 

After touching down, i engaged the reverse and my tbm went full left, anyone had this ?

Yep, for me too.

it may not be due to reversers, i noticed that after disconnecting AP, the rudder trim was set full left ( Crosswing 25 kts from the left)

even if you centered rudder trim, full reverse still set you left. I tried several times.

because I am not real pilot, I cannot comment on that

Prop torque, maybe?

Maybe reduce the amount of reverse thrust you are using?  The same principles of easy throttle adjustments in forward flight apply with reverse thrust.  It's a TBM900 not Draco

Did you turn off the Yaw damper?? To quote the manual it MUST be off before landing!

it happens when too much reverse thrust is added... and too fast.

when adding thrust while takeoff you also need to push the right rudder due to prob torque (prop is spinning right causing the plane to roll to the left around the longitudinal axis) - the same happens when using reverser: the plane starts rolling to the left, especially when going directly from "flight idle" into "full reverse" -> torque increases too fast -> "goodbye runway" 

so: increase reverse thrust slowly and push right rudder to keep the plane centered on the runway.

any questions? please ask

yeah thanks, i too used to airliners, applying full reverse as soon as main gear touch down lol
