I find it hard to believe a guy could mistake fuel cut off levers for the props...Especially since they were island hoppers doing many many flights a day. I guess stranger things have happened... In the 6000hrs i flew the DHC6 id never heard of it but had come across the mod in Africa aswell. The other thing is a full twin otter with a failed engine my just take you to the scene of the accident in some cases... Anyways i guess will see what comes out of the investigation
