Even if there is a chance of jamming one thrust lever,where would you fit this in the QRH?
As I see it,this a case where you can not adjust any more the thrust on one engine,right? So ,quite similar with no engine response at thrust lever movement.In both cases ,with or without lever movement you'll have N1 stuck at some %.
This case (no response to thrust lever movement) is in the QRH, as opposed to lever jammed (which is not) ,and the indication there is land asap.
