Torres Air Accident Monday 3rd October
A Bn2 has reportedly had engine issues at Kubin Island (Moa) in Torres Strait’s.
Unsure if departing or arriving, all passengers and pilot ok. Good to hear. Aircraft a write off.

It will be interesting to learn further of this incident.

The BN2 system at its most basic, could not be simpler: one tank, one engine. Job done. Just make sure there is enough for the job.
Correct, unless they’re gas turbines (Rolls/Allison’s) they’re Lycoming 540’s. 260hp carburetted O-540, 300hp injected IO-540.
And that’s where the subtleties come in… in the carburetted engine, unless there’s been a massive fuel leak, your fuel management is done (see above). The injected engine however, will pump around double the required fuel to the FCU, with the excess being returned to the tank on the same side as the engine. In a x-feed situation (for whatever reason) transferring fuel to the tank not in use. Very much a trap for young players, or drivers that just love fiddling.
Add to that the possibility of tip-tanks. They’re pretty basic too: their fuel simply pumps into the adjacent wing tank, which feeds the engines.
None of this is an analysis of the crash in question. Just some thoughts on what may or may not be a double engine failure.
Whatever the cause, a remarkable job done saving all lives on board, apparently without injury, despite destroying the airframe.
Concur. Double engine failures for mechanical reasons are (almost) as rare as rocking horse ****. Which reduces the possibilities to the one common system: fuel -lack thereof or supply mismanagement.

Might have made Kubin airport if he/she had reduced to best glide speed?

You're missing my point...What is the best glide speed?
Best glide speed is the airspeed at which the aircraft glides the farthest with the least loss of altitude.
I heard they may have forgotten to retract the landing gear as well, can't have helped the glide range...
Dug up this while thinking about this incident. Maybe some similarities WRT to airspeed management, might not be...

Best glide with both feathered would probably be close to blue line, would definitely not be a high speed with that airframe. Blue line would be at least close and safe to use. I know in heavier props recommended glide is just north of V2 type speeds. Haven't flown a BN2 so have no idea if there's a listed glide speed.

BN2 + Gliding cannot be used in the same sentence!

Extremely glad that Pilot and all Pax are ok, but I simply cannot supress a small feeling of relief that there is now one less of those infernal, Bullworker aileron, Pilot deafening pieces of machinery left in the skies!
And yes, the above is posted tongue-in-cheek! The bit about the Bongo Van that is...

Do we know for sure that neither engine was operating? Could it be the PIC may have had one or both producing a little bit of power?
Whatever the cause was you can’t complain about the outcome

Thank goodness this time the odds lined up to help on this occasion. I know nothing of it except everyone survived. Big thumbs up from me!
