jetbox ----------can you say "combining gearbox" then?

I'm not sure if you're agreeing of disagreeing with me Cap.

Let me clarify my position. When I say "older twins" I mean 212's, twin stars, and anything designed before 1990 (with the exception of the Super Puma which I understand has fabulous one engine performance)


When I say newer, I mean the EC135, 155, Explorer, S92, etc. What I consider new generation A/C. I haven't really heard of any catastrophic failures associated with these newer design helicopters. If anyone knows of any, please enlighten me.


As far as gearboxes, I don't know much about combining gearboxes but I understand that the Astar gear box was tested for six hours at max power with no oil without making any metal. Traditionally, main gearboxes don't seem to be an issue. Although I remember an incident with an input quil on an S61 on the west coast, and wasn't there an issue with C-boxes on 212's a while back????


What I'm trying to say is, I don't think newer designs are prone to failures as much as 20 or 30+ year old built aircraft, single engine or not.

The rumour may be true!


I think the whole Alberta oil patch is going twin bird. Throughout the oil industry including the offshore environment, insurance rates dictate requirements and eventhough most flights are overland, for insurance reasons twin engine helicopters will become the standard. During the evolution and 90's boom in Alberta Oil standards where such, but with the active involvement of thrid party consulting companies like Contrail, safety requirements and what the insurance companies demand will change.

Jetbox ------ doesn't make much difference whether you have two engines or 12 engines because if the C-Box "let's go" the engines are just along for the ride like you. :D


Secondly, I wouldn't be too quick to supposedly "dump" on any of the R/W twins and their SE performance because a recent stat from the F/W world tells us that we are not alone. That stat tells us that of ALL the light twin-engined F/W a/c in the world at present, only 35 will maintain flight at "all-up gross weight". So when you loose an engine on a huge proportion of those twins, you also fly to the crash site or start throwing passengers and items out the door to maintain that flight. Light F/W twins don't autorotate all that well either believe me. :lol::lol:
