ASW 27 destroyed by lightning in trailer
Even If it were throughly inspected and repaired I wouldn't buy that glider.
NFW Just saying |

Jim I will bet a steak dinner for two, but my criterion for losing would be a fully documented repair of the existing airframe in compliance with factory repair procedures and full F.A.A. documentation and the name and address of the Inspector. Steak dinner bet expires in 12 months. But I admit I wish we lived in a world that would allow this bird to return to service. P.S. Argentina does not count. Scott |

I've read and heard several times that lightning rod systems can and do conduct a lightning strike to ground. For example: "A lightning rod is very simple -- it's a pointed metal rod attached to the roof of a building. The rod might be an inch (2 cm) in diameter. It connects to a huge piece of copper or aluminum wire that's also an inch or so in diameter. The wire is connected to a conductive grid buried in the ground nearby." https://science.howstuffworks.com/na...lightning7.htm I'm sure some of them also work as you described, and that the system design depends on the what's being protected and where it's situated. Trying to control lightning is like herding cats. You get it right every now and then... After fifty years, they mostly gave up driving ground rods for light poles. They realized they are one big waste of time and money. They serve no purpose as to there original intent. Some thought it was to protect from lightning, some to protect humans. We are installing new lightning protection on a 14 story building. Cost the owner about 100K. Who knows if it makes a difference or not. But, we all feel better knowing it's UL listed and approved! Hopefully, lighting will find those two 37 strand aluminum downlead wires to its liking... UL only requires a 1/4 inch down conductor - now, how much current is that going to conduct. Well the answer is something in the neighborhood of 100A. The reason is that the induction of that conductor (yes, straight wires have inductance) will limit the current to that range. You have to ask yourself, that isn't much energy, where does all the rest go? To other potential conductors, is the answer. |

Jim It will depend upon who may choose to accept the long term risk. It is very reasonable to expect that a thorough inspection can determine the path the energy followed. Most likely it went to the elevator control circuit which is easy to trace. Witness marks on the trailer will be important and useful. Replacement of the vertical tail and aft fuselage would be the most straight forward repair. That section is about 9,000 Euros plus shipping. The major issues for someone repairing this a 1) Repair and refinishing cost; Value of these after completion would be on the order of $40,000 or so. 2) Next buyer will want at low price reflecting reluctance of future buyers.. Accordingly the margins won't be great. 3) Any future accident could lead to look back to history. Creative lawyer could have a field day with this given the Schleicher letter. 4) If someone qualified to inspect and repair the ship did it for himself, and kept it, they could do well. I have brought a lot of "totalled" gliders back from the dead over the years. # 26 is in my shop now. Each has had an analysis of risk and reward before proceeding. Mostly this is "how hard and long, and what will we get for it?". That can be figured out. Rolling in the unknown forward liability risk is another matter. Without the letter, it likely would be different. Ironically I have the fuselage and tail section needed, but it just got committed to another project.. My bet is that it will fly. I hope so. It's the only glider I know of with a lake dunking and a lightening hit. UH |

UH There is a no longer flying Discus A that took a lightning hit in flight, but met its final demise in a canyon near Bridgeport, California. But, I agree, Admiral Nixon. That is a special 27. I hope it gets back in the air, too. Steve Leonard |

Due to much smaller root of a 27, lots of work to mate 27 wings to a 20..,,.,

A sharp Sawzall, a couple of gallons of Bondo and a pot of coffee should make short work of that 27 wings to 20 fuselage conversion.
What could possibly go wrong,? Same manufacture. T |
