I'm not sure - I'll check with Vince - but he did say he found that the low speed needle valve on the engine that went out was open way farther than the engine that kept running. Which means that it was drawing more fuel. Ultimately running out of gas.
That MAY be a way to determine the failed engine, but I wouldn't bet too much on it.
If the spinners/props are still attached to the engine/ nacelles... Compairson ofscrapes and 'wipes' on the spinner will tell you the good engine wasfunctioning until impact, broken or whole props can tell a story too (most of the time).
...Anyway, Is he planning on repairs or replacement? That was a nice plane.
