Plane Lands on CA Highway

Pilot says the fuel selector valve broke in flight so he could not switch tanks. He radioed SBA to tell him he would run out of fuel and land on the highway.
Wonder if the PA-24 fuel selector is like the PA-30. I can see this happening if thats the case. There is a single recessed screw that holds the handle on the fuel selectors in the PA-30, and it can easily come off in your hand, making it difficult to switch tanks.

So, if this is true, he must have run one tank almost dry before deciding to change tanks, then discovered the selector was broken? Otherwise, I would think you would still have left yourself enough fuel in the original tank to make it to a nearby airport before running out. No matter what, this is critically poor fuel management - no exuses.

Then top it off with trying to land <i>against</i> traffic. Brilliant.
 
The white VW is stuck into the tail, so I'm guessing as usual the news couldn't figure out the small difference between 'oncoming' and 'with' traffic.
Standard incompetence on the part of both news media and the American driving public.
Anyone have any idea how long from touchdown to, uh, impact(s)? The drivers of the cars should be beaten with a towbar if they moronically watched the thing fly over their heads, then hit it. But this being America, land of the ignorant and blameless, they'll probably sue the pilot for making them spill their coffee and be late getting home.

Do Comanches have just L/R tanks or are they like a Bonanza with a bunch of tanks? I'm wondering if they got in cruise and went to an aux to burn it down, then went "UhOh", went they tried to switch back to another tank.

My only engine "failure" happened because of a fuel selector on a Twin Comanche. The linkage arm got jammed and bent and I couldn't switch to the full tank. Once I got on the ground (single engine) I could get into a position to work the linkage and get it moving again, but I sure wasn't going to try doing that while still flying the plane. Self-induced unusual attitudes may well have followed if I had.

I seem to recall that we used to try to run them as close to empty (sputtering anyone?) as we could to make sure that we used all of the fuel available. It was a good check of actual fuel burn per hour, and gave a pretty accurate picture of how much fuel was left in the total system. Maybe it was poor fuel management on our part, but I must say I'm not really convinced of that at this point. Kind of like to hear you expound on that a little if you'd care to. :confused:
 
It's fairly common practice to run the tank nearly dry before switching. I guess there are (now obvious) reasons not to; but I doubt the poor guy had any idea the fuel selector would break off in his hand, though!

Can we be so certain about this? What if it broke between L and R, not necessarily on one or the other. I need more info before I agree with your statement...

Same here, as the MEI I reached over and turned the fuel off to do a full procedure shutdown, feather and restart with a student. He went through the procedure perfectly right up to the point where he switched the tank back to MAIN. He hands me the fuel selector handle and says "now what?" :D

We landed single engine at a nearby airport and an Allen wrench for the recessed screw repaired the problem, but like you. Standing on my head and lack of the needed tool prevented any airborne fix.

So like a couple others here, I am gonna wait and see before jumping to conclusions on this accident.
 
Been a while, but I seem to remember that we would take off in the Twinco on the main tanks, then switch to the aux tanks and run those until we'd get some fuel pressure fluctuations (starting to run dry), then finish off on the mains.

Maybe the single engine Comanche is a little different, but as I recall from waaaaay back in my memory we used to fly the Warrior and Archer (over ten years ago so memory might be faulty!) by starting on one side, run it down to 3/4 tank, switch and run the other side to 1/4, and switch back to the first tank. The Comanche typical operating scenario is probably similar, with the addition of some aux tanks maybe.

Any way, operating in that manner would have us cycling through tanks at least once well before a tank runs dry. That way we were sure of proper operation while we still had plenty of fuel in the currently selected tank(s) just in case there was a problem with the mechanics of the system. As long as that happens I think we've done pretty much everything we can to assure that the system is going to work properly later in the flight, and I don't see a problem with running tanks down in order to get max range and best use of reserve fuel.

True, the media probably has that wrong....I hope!

Sure, I'm glad to expound on it. Yes, in some situations it might be common practice to run tanks close to empty before switching, but it was always in what I would call a "controlled environment". When I flew Navajo's for charter, there were times when I would run the outboards pretty low before switching back to the inboards to get max fuel usage [never dry...1) passengers don't like to hear engines sputter, and 2) you can spread your reserve across multiple tanks, right? Good insurance against just this kind of situation ;) ]. Takeoff and landing was required to be on the inboard tanks. The switch to the outboards happened at cruise (at altitude and/or within range of a landing site), and the switch was staggered, ie: one at a time. Switching back to the inboards was the trickier one, <i>because if something went wrong, I was fully aware that I might get stuck on a tank with little fuel</i>. For this reason, the switch back to inboards always occurred at altitude and staggered by a minute or so. I had the luxury of being in a twin, meaning that I always knew that if I had problems switching back to the inboard on one side, I would have to be extremely unlucky to have a similar problem on the other, completely independent side. It would suck to go single engine, but at least I had the other engine and altitude to get me were I needed to go.

I would say that running one tank nearly dry in a single Commanche before switching is a completely different story, if for no other reason than that you lose the redundancy in a single....you have to realize that you've painted yourself into a corner in that kind of situation.

And what's wrong with calculating an accurate gal/hr by filling the tanks, flying for a while, fill 'er up again...I don't see why you have to run a tank dry to get this information. Gallons used is gallons used no matter how dry the tank.

All that being said, I realize that it is unfair to jump to the conclusion that any of this had anything to do with this accident.

It's fairly common practice to run the tank nearly dry before switching. I guess there are (now obvious) reasons not to; but I doubt the poor guy had any idea the fuel selector would break off in his hand, though!

I honestly didn't consider that perhaps the selector "broke" at some midpoint that caused fuel flow to stop altogether. I wrongly jumped to conclusions here, mainly because it's painfully common for pilots to run out of fuel, and 99% of the time it's because of something the pilot did or didn't do or misjudged.

I hope, for the pilot's sake, that this accident really was something unavoidable. History isn't on his side, though. In the meantime, as other posters have said, it's best to resist the urge to speculate, and let the investigation sort everything out. :)

Agreed...essentially all I was getting at in my earlier posts is that there is definitely a difference between running tanks down to reserves versus running one practically empty on the flawed logic that you still have a reserve in the other tank. Obviously it's too early to say anything like that happened in this accident...I shouldn't have implied that in my first post.
