Heh. Here's another of those "Gotcha!" stories. Not too long ago at PHI, two very experienced pilots landed their 412 and shut it down to take a lunch break. Inadvertently, one of them switched the fuel controls to "Manual" (instead of shutting off the fuel valves or whatever it was they were supposed to do).
On the next startup, the error wasn't caught. Everything went fine...until the rollup to 100%. Then, BOOM!...or whatever noise is made by two PT-6's going for the moon. Two very red-faced pilots with two very oversped/overtemped Pratts. If I recall, I think those guys got the dynamic components too. Very good job, fellas! Good design, Bell! Ahh, but in Bell's defense, the antique 412 was designed so long ago that people probably hadn't heard of "human factors" yet.
