That's not surprising. Any twin that can't maintain altitude on one engine, has to be a pig in ice.
Oh, my guess is the Beech 18 will maintain altitude on one engine on wheels. ( of course it depends on how high you are. )

Here is a question to ponder.

Will a Beaver, Otter or any other single engine float plane fly as far after losing an engine as a Beech 18 on floats will?

NOPE.. I watched one do a long, shallow approach on one engine one day. INOP engine was feathered...

Not sure what is happening with the aircraft but Carholme who is the owner of Dax Air is going thru some serious medical issues and certainly has more on his plate to worry about these days than a Beechcraft.

CL guy, you might want to try a corporate search before making statements regarding company ownership.

Ah, but lets play the ods Cat..

-One R 1340 H1G; probably gonna fail sooner or later...
-One R 985; probably make it to TBO w/ out a catastrophic failure...
-Two R 985s; Well - your probably just got watered down a little, don't you think?

A plane with 2 engines is more likely to have a single engine fail that a single engine plane is to have its only engine fail, assuming the engines are identical and stressed in the same way. If you need both engines running in order to remain in the air, a twin isn't necessarily as safe as you think.

no sig because apparently quoting people in context is offensive to them.

Here's the math assuming that the R985 will fail one out of two thousand flights:

Probability that LH Engine fails = 1/2000
Probability that RH Engine fails = 1/2000
Probability that both engines fail = (1/2000) * (1/2000) = 1/4 000 000
Probability that either engine fails = (1/2000) + (1/2000) - (1/4 000 000) = 1.9995/2000

Almost twice as likely to have an engine failure in a twin Beech. Now the question is are you almost twice as likely to have a successful landing in a Beech 18 on one engine as opposed to a single with no engine?

I know its trivial, but, your equation only considers the engines being operationally unrelated. But they share something in common: fuel. What are the odds of the 1/2000 chance of engine failure being caused by contaminated fuel? This could suddenly apply to both sides, making the odds of both engines failing a lot higher than 1/4 000 000. :rolleyes:
