Its been a while since flying the KA200. The aux fuel, is it electrically pump or does it use the jet pumps from bypass fuel? I seem to recall that if there is no fuel in the mains, it wont transfer? Maybe an alternate theory was lineman filled wrong tank, and in hurry crew simply looked at total litres, but not enough fuel in the mains to siphon all from the aux's...... and tried to stretch it.

It uses a jet pump that takes fuel from the motive flow valve and the engine driven boost pump.

It’s nacelle fuel that you need. If you don’t have nacelle fuel, you’ve got more problems.

You’re not supposed to have empty mains and full auxes, and it’s not really possible to burn the mains and the nacelle dry first on both engines unless both motive flow valves are stuck closed and you’ve got both no fuel transfer lights on.

But yeah... I don’t know how you don’t grab enough gas either. Order the fuel, watch them fuel, get the fuel ticket and look at the amount, look at the gauges, read the checklist. Not one but two of you.

I believe they declared a fuel emergency shortly before actual event. Fuel gauges on this aircraft are not great and are MELable. Been there done that. If they were, there is no cockpit indication of fuel on board and first indication would be the fuel pressure light. For whatever reason they didn’t have the fuel they thought they had.

These aircraft are G1000 equipped. Provided you punch in the right fuel load on start up it will automatically calculate what you will have on descent and be reasonably accurate.

The auxes are transferred directly to the nacelle tank via the jet pump and to the engine. A flapper valve keeps the main fuel from entering the nacelle tank until the auxes are empty and the nacelle level/pressure drops due to the jet pump stopping.

It is possible for main fuel to be contaminated and aux fuel to not be. Unlikely, but possible.

Since the mains are always filled first, and the aux are always burned first......possible, you say? When pigs fly.
They ran out of gas.....still nobody willing to stand on their hind legs and say it?

With a huge Mb medevac contract under decision you can bet EIC will be doing all they can to brush this under the rug as Keewatin was their best player to do bidding with. I’m actually surprised the LifeFlight/union folks and gov opposition aren’t using this as ammo against the privatization.

Stranger things have happened.

Sediment or water is going to be the first thing drawn out of a tank. First into the mains held back from the engine by the flapper valve, and will go to the lowest point on the nacelle tank as soon as auxes are dry.

I don’t really care if they ran out of gas or didn’t. They probably did. Why is that so important to you?

Doc just wants to blame people.

That being said, it does take some skill to either have a dual engine failure or run out of fuel in a twin turbine. I can think of a couple instances, but it's pretty rare. I'm willing to bet that the combined experience in the cockpit totals less than the average of our King Air F/Os.... pay peanuts....

I heard they are in the middle of pilot contract negots. Tough to negotiate with the boss if they did burn the tanks dry.....

Why is it important to me? Seriously? Doesn't bother you to have crews flying around running out of gas? Bothers me.

Cause we can't say for certain that they did. Looking likely, but not for certain. It bothers me IF they ran out of gas, but I'd like to give this crew the benefit of the doubt first. It's the shoot first, ask questions later style that bothers people.

There is the possibility that it is fuel contamination, but yet some posters come across that they want it to be empty tanks so they can continue their rhetoric that pilots run out of gas. A very self supporting conclusion, not drawn from facts, but speculation.

Maybe the apprentice put both fuel systems together wrong? It's anybody's guess how it would behave then. Perhaps the fuel gauges were way out of whack and they thought they had enough? Fuel leak?

What bothers me is the rationalization that speculation is ok because it is all about learning.
And that we need to know right now.

I predict that the cause of this accident will not be the first time that it has happened.

Which makes me wonder why the all fired rush to need to speculate at all. Or castigating TSB for taking the necessary time to get it right. Unlike many here, they have the annoying habit of checking everything.
This should be an easier case because the crew is available and the plane is pretty much intact.

Lets all wait awhile shall we.

Then we can bring out the tar and feathers.

It is bizarre. There will be all this endless speculation and arguing on a thread after an accident. Then, it eventually stops. After a year or two a report comes out and we find out the actual story(perhaps not always but frequently). It gets posted by someone like me and there is a fraction of the discussion.

Not really. The final report usually says exactly what happened. There is much less to talk about. It's usually also one of the many options that people already speculated about. A lot of the possible options have already been "pre-discussed" if you wish.

The only thing remaining could be the discussion as to why it happened, or what lead to the accident, but even that is usually covered in quite some detail in the TSB report.

Pelmet.

It is as you say.

People seem to enjoy speculating without any facts.
When the report does come, there seems to be no desire to learn from it.

BTW. I read all your accident posts. I have found lots to learn from them.

If you were to post a TSB report from an accident that nobody heard from before, there would be much more discussion because a lot of new possibilities and "what-ifs" could be discussed.

That's where you are wrong. The speculating *IS* the learning: what could have gone wrong, why could it have gone wrong, who or what caused it, etc.

For example, viewers of this thread have now a better understanding of the King Air fuel system. Information that probably wouldn't have been included in the TSB report.

If you fly a King Air, you will, or should have, an understanding of the fuel system. It is, or should be, part of the training. If it is not,then your training organization is the place to learn it.
If you do not fly a king air, exactly what value does learning about a king airs fuel system do for you. Allow you as an anonymous future poster to pretend you understand the system? don,t you think that should be part of a training program and not a casual internet thread where you may, or maybe not, be getting factual information, or maybe it only applies to certain models and years of king airs. A little knowledge can be very dangerous in an airplane.

I am very biased towards good and thorough training. Not so called learning from speculation. To many computer captains who really don’t know much pretending they do.

To put it bluntly, “ the learning” is just an excuse to gossip.

The above should end this discussion because it is factual.

However I do have one question to ask.

If a crew wrecks an airplane through gross mismanagement such as running out of fuel should there be a price to pay for their mismanagement... or is just a learning experience?

If it truly is taking off without enough fuel, and continuing on regardless, then wrecks the plane and survives. Then it will probably cost them their jobs and careers.

If somebody does take off without enough gas, own the mistake, turn around and go back and get more. You'll get in shit, but that's the least of your worries compared to continuing on and running out.

If it's a fuel leak, fitting vibrated loose and dumped fuel at scary rates, then could be "good job making it almost to a runway".

A lot of "if" statements because nobody on avcanada knows why they maybe ran out of gas.

If a crew wrecks an airplane by running out of fuel because they did not have enough in the airplane for the trip would the insurance company pay for the damage?
