Montblack I've been around since 1998 - starting in r.a.s. Wasn't there a gentleman who not too long ago died in the crash of his SQ2000 canard that posted on R.A.H. My memory fails me but it seems he had installed an Franklin engine? and was having overheating issues. I don't believe he had much time at all on it. The SQ2000 guy was flying a rotary (mazda derivative) engine that had what the rotary community believes was an intermittent fuel supply program and was in flight test at the time. The aircraft had made one dead-stick due to what the community assumed was a vapor lock. This was a fairly low altitude turn back and landing on-field but off-runway. After some re-work on the fuel system he went up again, and on one of the subsequent flights weeks later lost power very low, and tried to make another low turn back to the runway. He ended up in trees. The rotary powered aircraft community participated in both the NTSB investigation and afterwards several purchased the airframe from the widow and did additional information gathering. Nothing definitive was determined from a cause standpoint, but one of the fuel injectors (which was used, not new) was found to be faulty from a flow standpoint.

Don't fly myself, but in a lifetime of reading I've seen several references to crashes occuring from pilots trying to turn back to a runway when they had a reasonably flat bit of terrain in front of them. It's been said that Post knew better, but had the family fortune tied up in the plane he and Will were traveling in and just let that drive his decision making. What do some of you actual pilots think? Harold KD5SAK |

What do some of you actual pilots think? Harold KD5SAK It's hard to put any iron clad rules on it before hand as the situation you are dealing with could be quite different each time. I've never had one quit completely on me. But I did have a C-85 sag rather dramatically on takeoff to the south from Crystal River in Florida. I had been idling too long and the plugs loaded up on me. (Leo had trouble starting the T-Cart and I went to help him.) I "burned them off" by running up a bit until the mags checked ok, but at about 300 feet the thing went sour again. I just got in a hurry to catch up with my lead. Foolish lizard. Hotel about 1/2 mile straight ahead(!), Interstate with bumper to bumper traffic to the right, and a 4000 foot paved runway directly below (cross ways). I mean directly straight down... Damn it but that hotel suddenly looked real big! I turned left for the cross wind runway, crabbing away from it in order not to be blown further north, with the idea that if it did quit I'd rather "land" someplace on the airport that in a parking lot. The engine cleared in a dozen or so (very extremely way too long!) seconds and I decided to abort the abort and head on home. But I think the upholstery pattern is still imprinted on that pair of jeans... Thinking back on it (way after the fact), I probably should have turned a little further north and let the wind blow me across the runway to set up for a right base. I don't think I'd have made the runway if the engine had quit from where I was. It would required a real tight turn from base to final - down wind. But I may have been a _little_ distracted and didn't think of it in time. Sonny sez, "The problem with aviation is that you can't make the same mistake _once_". He has a point, you know. Richard |

Richard Thanks for the reply, after reading about it so often over the years I've often wondered what actual pilots might think. Nearest thing I've had happen was motorcycling. Cornered a long curve much too fast and drifted off the road and shoulder until I wound up paralleling a 4 strand barbed wire fence about two feet away at speed. Don't know how fast but had slowed some by then. Stayed out of it and finally crossed back onto the road but kept thinking, "self, you should have layed it down".I think it's almost always better to be lucky than smart when critical decisions are necessary..

I will never forget shortly after I traded my Honda 305 for an Earles-fork BMW. I went tearing down the road following my friends. When we came to the Interstate, they all gracefully took the 45 degree turn onto the on-ramp while I (using the techniques learned from the sprightly little Honda) only managed about 22 degrees...

Granted they don't face the same situation on such a regular basis as the glider pilot, but as the group is discussing, it would be a valuable skill. Steve |

There's a difference between a glider with a 30:1 L/D and a Cessna with
9:1. Doing a 180 in a glider from 400' is like doing it in a Cessna from 1200'. |

I was tempted once, but the temptation went away with the
altitude...quickly. I lost an engine on a C210 at about 300 ft, on departure. The thing quit like someone had pulled the throttle, which turned out to be very close to reality. In the shock of the moment, I thought about trying a turn, but decided to plant it off the end of my departure runway(I was 3000' down a 4000' runway), instead. The clearway at the end was level and had no large trees. I had already cleaned up the departure flaps, was climbing at 80kts, and the gear doors were just closing when the thing quit. I immediately selected the gear back down, and was flat amazed at the sink rate that developed, no power, windmilling, with the gear in transit. At about 20', still over the runway, I had to hold it off using flaps, to wait for the gear to finish extending. The main gear came over center in the saddles, just as I ran out of elevator, we touched down on the mains, and had to hold the nose gear off long enough for it to extend. I slid onto the numbers at the far end with the gear pump still running to close the doors, and got it stopped. The engine lit off, and we taxied back to the tiedown, and deplaned. It turns out that this aircraft had recently come out of 100hr., and for some reason they had the Airquipt(sp?) hose that runs from the air cleaner to the turbo-charger off. When the mechanic put it back on, he didn't know what to do with the ends of the metal wire that winds around the inside of the hose. He bent each wire end into a little "U" shape, and hooked them together in the middle of the hose. (They should have been placed under the hose clamp at each end) A couple of hours later, with vibration, the glue holding the wire failed, and hooked in the middle the wire collapsed like a slinky, allowing the hose to collapse, shutting off all air to the turbo. What really amazed me was how fast the altitude and airspeed went away. When the thing first quit, I would have sworn I could not get down to my departure runway before going off the end. I was wrong. Wrong by over a thousand feet. Al CFIAMI "kd5sak" wrote in message m... "Dave S" wrote in message nk.net...

Al CFIAMI I'm beginning to be glad the wife would'nt let me buy a kitplane when I first retired 10 years ago. You guys have some real interesting stories to tell. Hmmm, someone should start an aviation close calls recounting group. Harold KD5SAK |
