SkyWestCRJPilot said:The straight Navajo (PA31-310) doesn't have counter-rotating props but the Navajo Chieftain (PA31-350) does. The most noticeable difference is you don't need lots of right rudder on climbout in the Chieftain like you do in the Navajo. The other big difference is the obvious safety of not having a "critical" engine. Both are equally "critical" though. The drawback is that your maintenance may be more expensive because you have more different parts for the engines instead of the same exact engine with the same parts.
I think that that's only true with the Dash 10 powered MU-2s, but I could be mistaked there. I seem to remember something about an extra gear in the gearbox of that particular model 331 that caused the props to rotate "backwards".WMUSIGPI said:Nope but like all other Garrets (J31, SA227,B100 ect) both props spin opposite to the "normal" clockwise spin.
gern_blanston said:Absolutely right. BOTH engines on a piston twin are critical. After an engine failure on a normally-aspirated light twin, what you've got is the same situtation you've got after an engine failure in a '182: You're in a glider. a Baron or Twinkie'll glide quite a ways on one, but you're not going too far.
