Point well taken! This does bring up and interesting question. Let's assume we have had an engine stop running in cruise and there has been no apparent loss of fuel from the wings. Years ago during my multi training one of the trouble shooting steps to attempt to regain the engine would be to attempt to x-feed fuel to the engine not producing power (try to get fuel from another tank). I have a 1973 C337G (no turbo, no pressure) and this configuration is not addressed anywhere in my manual. The manual does not suggest it as a trouble shooting step or pohibit it. I do however have in my posession an old "Air Facts" magazine from 1973 where a review was written by Leighton Collins (father of Richard Colllins, Flying magazine editor for 1000 years) of the brand new 1973 P337 (yes, pressurized model). In this extensive column, Leighton writes that under no circumstance should both engines be run from the same wing at the same time as this can result in double engine failure. He does not however explain why. I was always curious if this was true and if it applied to my non-pressure model. I have asked my mechanic about this and he cannot see why this would be the case. I have tried running on the ground with both engines running from the same wing with no problems but I have not had the desire to attempt it in flight. Can any of you 1973 P-model guys confirm this and explain why. I am not familiar with the P-model fuel system. Is it different then the non-pressure model of the same year?
I do have a theory but I do not know if it is true. Is it possible that with both engines running from the same wing that fuel could be drawn from the boom tank faster than it can be replaced? It looks as if that small boom tank only holds about a gallon or two of gas though I have never actually messured this? Any feedback!
Thanks Ed
