Thinking of it again, I had a TSIO-520 fail on take off very recently, although it wasnīt in the nose of a Bonanza, but a Cessna Ag-Husky. Course of events since checking for traffic before TO:

- Added power slowly, to get to the max for that DA (39'') while readjusting prop (otherwise it'd go to one million rpm) and mixture (otherwise it'd think it was feeding the Concorde), while letting it start running.

- Noticed the manifold wasnīt quite climbing to 39'', but being where it was... operation normal. Still, better than the two previous years, when it would barely go beyond the green (very bad need to pay a mortgage).

- Everything else looks good. Sound is good. Acceleration is good. Up it goes.

- Somewhere below 200 ft, cause thatīs about the top the ferry altitude, the noise goes away, together with some speed and a couple quick bangs serve as drums.

- Nose down and pointing to the previously selected side road.

- Off goes most of the load, mainly to get lighter, but by chance it also helps advise the incoming traffic that it's not a good idea landing opposite and underneath now. A crop dusting plane has that kind of advantage, while you canīt kick your passengers out of the Bonanza that easily.

- Canīt have much left inside, so leave the handle alone and let it drain like that, cause the fully, forced, opened door is a fantastic brake, that also tries making your nose point to the stars. The road is there and Iīm gonna make it with time/altitude to spare. Not that bad a brake this way, so no urge to pull it for a complete closure. Also, I can use my hand in something else, and even open the thing again and use it as air brake if I need to.

- So here we are, in the air and not much else to do than wait, of course after dedicating a sentimental thought to your mechanic's ancestors. Not that you can read a book, but still...

- Are the mags alright? lets check. They are on, and switching to one or the other makes no difference.

- Mixture? Itīs where itīs supposed to be. If something magical happened to the cable and it went opposite to where it goes when it breaks (happened next day, BTW), I donīt know the spell to cure it, so next thing.

- Throttle? Lets see what happens moving it around. Happened that the darn thing fired again, although at very much idle. Compared to nothing... idle is what one normally uses for most intentional landings, this power is about that, so it is great!

- Close that emergency drop gate.

- In all joy, find now the spot in the road, if thereīs such a spot at all and it's within reach, that you can use to park the plane, not making a mess of the scarce traffic and not having to push a lot later on (had something very similar happen last year, just more smoky, and in minutes I had a trailer behind, driver asking if it was going to take long). The spot does exist and I think I can get there.

- Pull on the harness to make sure it is still in tourniquet mode.

- Slowly to full flap. Softly touch in two points (itīs the dirt road I use to get to the strip, so I know itīs reasonably flat and have used much worse to work), let it run, let it get closer to that bit with the flat and apparently hard shoulder... The tail finally goes down, speed goes down and the plane is by that part of the road. Kick the rudder and, while not letting it go out yet, at least leave the wheel pointing in the right direction.

- Off the harness, open the doors, check thereīs no paddle of fuel around, shut everything down, vacate, smell while walking away and looking, check that the side of the road is really alright and push it in there.

Happened to be a one mile long, one thousand years old, intake pipe, that had collapsed, shrank and choked when trying to suck at full. Maybe opening the alternate air would have been better to recover more power, but didnīt even try. For once, the handle had been fixed in the "closed" position since 1975 and my previous attempts at moving it on the ground, out of pure boredom, had been unfruitful, but more importantly, by that time I was *really* close to landing softly on a perfectly fine road. Had it been a mined camp full of vertical stone walls, I'd have probably tried and succeeded in pulling that handle out, together with the cable, panel and the whole engine.

So no, I didnīt use the pump in that instance. Still, there was time to try a few things, among them, the one that helped getting a somehow different landing. Could still have made a fine landing without that little power, but it helped making it smoother and, more importantly, helped spirits! <g>

The main question is, I suppose: specially if, or when, you are flying low on a SEP, you have to know where you are going to land when the engine quits. Far from being a constant estate of intense stress, it can be just the contrary in a critical moment. It becomes a natural part of your flying, that you donīt even notice, helps you saving those first precious seconds, keeps you from having to choose the second-to-best place because the best one was within range a second ago, takes away a lot of the uncertainty stress in the worst possible moment... It can end up being not much more than a landing, with a thought of "dang, why did I put the expensive shoes on today? And I thought landing fees in my airport were expensive. Do I have the # of my mechanic here?".

After all, quite a few of one's circuits in a piston single start under 1000ft, donīt do they? and you still do a lot of stuff and whistling on your way down. The strip now is not a 10,000ft long asphalt airport, there's probably not a bar there, your pocket is going to hurt and the engine is developing zero power, not idle, alright, but you had seen the place before from above, have pictured yourself landing there, have made some landings before i your lifetime (had one planned for that flight, in fact, just not exactly there) and thereīs nothing else you can do in those seconds, that can become eternal, than try one or two things to make it softer or even avoid it altogether, if it was something simple and easily fixable.

When low, always keep an eye in the less bad spot and see yourself landing there. At the very least, it's yet another entertaining thing to do when flying. Then you have time; and from 1000 ft, an awful eternity.


PS: I could have saved telling the part where I chose a spot and parked there, cause it made me and the text look as it made us look, but the idea was illustrating the sort of thoughts you have time to have, and even put into practice, when you are low in a piston, but know you are low in a piston (and in this case, the area permits). Also, yes, that part was the virtual sunglasses and huge watch <g>
