Was not asking about engine failure in singles (even I had a flame out in an Iroquois in Nam) nor about 'double' engine failure in twins but ... a single engine failure in a twin.
Jellycopter has had it in a 109C. Congrats! You're the flirst helo jock I've 'met' to whom this has happened!
The thing is, and the reason for my asking, is that these incidents of mechanical engine failure must be very rare. I'm trying to establish how frequently a second engine keeps an aircraft from calamity vs. single engine. I guess Jelly landed pretty smartly after the failure but some twin ops (over water at night) etc. may require sustained flight.
What are the stats? Are twins statistically safer than singles?
