An excellent discussion following a tragic event.
As a part time tow pilot, I've seen uncountable practice rope breaks, all of which ended successfully. I also had one of our CFIs in his own Libelle have an actual rope break at about 250 ft on departure; surprised us both! ....But he bade a textbook turn back and landing. I saw about 10 feet of rope dangling from his nose but decided not to distract him by letting him know. Instead, when I landed, I thanked him for bringing back the Tost ring. My only other actual rope break was at about 2,500' AGL due to an incredibly ham fisted retired commercial pilot. He also brought back about 25 feet of rope wrapped over the right wing of the G-103. That was also a no-op. On my commercial glider check ride some 25 years ago, there was a 25 kt wind directly down the runway and the FAA examiner pulled the release at 200 feet while we were flying straight out. I made a successful turn back in the twin Lark (unlandable ahead) and landed about mid field, continued off the end of the runway, used up all the grass in the field at the end, put a wing on the ground, full rudder, and ground looped just short of the barbed wire. He just said, "Nice job." I thought it was an unsafe maneuver .. |

While there will be some interesting discussions about the safety/usefulness of this type of emergency training, I've recently become a fan. Last weekend we had the a Pawnee suddenly become a glider when the engine seized at 800' on tow. Fortunately, we had a well trained glider pilot in the tow plane, and he made a successful 180 to downwind dead-stick landing. The glider flew a full pattern to normal landing. We are grateful that 2 pilots well-trained in emergency procedures had such a successful and safe outcome. I was towing in the Pawnee with a student pilot, solo, in the 2-33. I experienced a strong vibration that appeared to generate from the engine. We were climbing through about 150ft AGL, and climbing the engine responding to the throttle but not reducing the vibration. I kept the student on tow until 250 ft AGL and calmly called on the radio, "call sign, release, release, release". The student pulled his release and executed a perfect 180 to a downwind landing, I reduced power, completed my own low downwind, watched him safely land and then turned close in to land into the wind. A safe outcome was never in doubt knowing the student had received the training required. I just had to hope that the engine would hold together for me to get the student to a safe return altitude. I had a stuck valve on the Pawnee that received the proper maintenance before continued towing. T |

KJC I've had a rope part after the glider was airborne but before the tow plane lifted off. Land straight ahead. I've had an improperly connected Schweizer hook release at about 50ft on it's own. Land straight ahead. And as previously reported, I've had engine problems with the tow plane and asked the glider to release at 250ft before the engine outright failed. (It did not fail.) T |

KJC i was towing last year when the rope broke at somewhere about 250 feet with our 2-22 behind. The pilot made a very excellent choice of taking the easy more or less straight ahead into the wind landing in a dirt field just north of the airport. |

I've seen several similar breaks over the years. As far as I know, our club has had precisely one rope break in the air in the 25 years I've been a member. It happened at around 1500 or 2000 ft and the glider end or the rope and the rings dropped into an electrical substation, which caused them to become a little unhappy. I don't know why people are talking about landing downwind from 200ft. When I've done practice rope breaks it's been about a 90 degree turn onto a short downwind for the crosswind runway, but almost invariably when you get onto base for that you figure you've got plenty of height to turn that into a close in downwind for the active runway. Certainly, if there's a reasonable wind (20 - 25 knots, say) then it's easy (and better) to go right around and land upwind even if you land a fair way up the active runway and/or still at a 20 or 30 degree angle to it. |

Bruce, because many gliderports have shorter single runways. You may be thinking of operating off long runways at larger airports with cross runways. Darryl |

There are two things important here. 1. The importance of being ready to handle the rope break by practice. Like it or not, this can happen and the importance of planning cannot be overemphasized. Which direction do you turn? Can you make the 180 and then make the field? Do you land straight ahead? Which field do I go for? Do I mush it into the trees? These need to be thought of in advance. The two or three seconds you hesitate might cost you your life. 2. The importance of doing all we can to reduce the possibility of an actual rope break.
This confirms the need for the hook up person to be vigilant in the inspection of the rope AND rings prior to launch. What percentage of a 200 foot rope is inspected prior to each launch? How often do we take a good look at the rings, either the two on a Tost or the one on a Schweizer hook? I try to catch the rope as near to the tow plane as I can and let it flow across my pants and thru my fingers feeling for partial breaks, I have found two in the last two years. I have also seen rings which were beginning to crack, haven't seen one out on the flight line but have been shown them in the past. These things DO happen. The myriad of things that can go wrong on tow such as drive brakes being open, canopy flying open, tail dolly left on and the like can be reduced or eliminated by using the checklist properly. The hook up guy can help to reduce these problems by being an extra set of eyes. Maintaining proper position on tow, watching for signals from the tow plane, KNOWING the difference between a wing wag and a rudder wag can save our lives at those critical moments. Remembering too that there are at least two and sometimes three lives at stake on tow. (or 4 in a 2-32.) To see accidents happen with DPE's, CFI-G's and otherwise experienced pilots drives home the need to remember that this can happen even to the best of pilots. If a current, experienced pilot blows it at a critical moment, what's going to happen to the guy who flies twice a year? Walt |

This is an obvious question when winching and the answer is always the same: downwind if there's any crosswind, because that opens the circuit out at minimal cost. I almost asked about it earlier in the thread and then decided that was obvious - you'd turn the same way as usual because that's what the tow pilot is expecting. So, is this the correct answer and, if not, what is? If a current, experienced pilot blows it at a critical moment, what's going to happen to the guy who flies twice a year? At my club he'd be given a mandatory check flight if he hadn't flown for more than a month and rocked up expecting to fly solo. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |
