Glider Towplane Mid-air – TP PowerFLARM Inop
What a tragic waste of lives.Â* The report mentioned that both occupants
of the glider were wearing parachutes, but there's no mention of any attempt to bail out.Â* Is that an oversight in the report or did they simply not try to get out? On 2/10/2020 12:32 PM, George Haeh wrote: TSB Canada Report https://bst-tsb.gc.ca/eng/rapports-r.../a19w0099.html -- Dan, 5J |

My guess is that they didn't have enough time to get out with the forces involved after the tail came off. The report does not mention whether the canopies were released.

Glider Towplane Mid-air – TP PowerFLARM Inop
In 2003 I lost my fin and tailplane in a midair. I was able to get out very easily. I and the pilot of the other glider involved were very lucky. We both used our parachutes and were completely uninjured. I would not speculate on why the pilots of this K21 were unable to get out and am surprised that the report did not address that aspect. Would any of you ground a tug because the Flarm was giving problems?

Would any of you ground a tug because the Flarm was giving problems? It sounds like they were about 2000" AGL. I would think that would give enough time to egress, assuming the G-forces were not pinning you in the seat, but it wouldn't be a lot of time. You would have to get out fast. |

Without a tail would the g forces not be 0 or even negative?. I would
expect the first result to be a bunt to inverted. Just wondering |

I saw a glider loose the horizontal in the landing flare, 20 some years ago.. It pitched up and rolled left before the wing dung in and spun the aircraft around nearly hitting me. The pilot is still flying nearly every Saturday, and is one of the local "heroes". Funny side note, I watched that landing as the weekend before that same pilot had ground looped and nearly hit me as I was putting my bird back in box. |

This seems to happen every few years, where the tow plane makes a left turn and the glider make a right and they come around and collide. I changed the way we do it here so that the glider only makes a slight right turn, and then keeps his eye on the tow plane, so that at least one of the pair of planes can more easily maintain separation. When both planes make a 360° turn, neither of them can see the other. This kind of accident is the result.

Did damage from the earlier ground loop contribute to losing the horizontal the next week? -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) - "A Guide to Self-Launching Sailplane Operation" https://sites.google.com/site/motorg...ad-the-guide-1 |
