340drvr and prop overlimit
There is a short in flight troubleshoot procedure after retyrding TQ to about 84% and see if the Np increased is below 101% (in whic case continue flt normally
Or if Np remains. Above 101% and conditions permit..shut down the affected engine and follow S.E. ops QRH procedure.
*red limits must not be deliberated exceeded.
I don't think this was the scenario.
