Ever tried an engine failure just as max thrust is reached? At low speed? Hardly the most unlikely time for an engine failure, is it?
One of the first things practiced in Multi-Engine school. The swing is just as bad, i.e. uncontrollable, in a Seneca as it is in 737. Seems like modern aviators have forgotten the basics, if this happens to be the case of asymmetric spool up. As an instructor I always sat with my left hand on the mixture control < 1000 ft with new schoolers. They were good, it was just that I wanted to immediately get control of the yaw if they didn't respond properly to the failure.
