I heard that the HEMS Explorer had an engine flame-out recently. Seems one engine simply ran out of fuel! The Explorer's fuel system leaves something to be desired, it has one tank split down the middle by a baffle. This can result in a fuel imbalance and, as each engine is fed from either side of the baffle ... you can work the rest out for yourselves. In addition it seems that the fuel gauge is pretty inaccurate!
So far the Explorer's problems have been kept fairly well under wraps, I think the lid may be starting to be prised off the can of worms. Good luck all you Explorer pilots.
