Safety of homebuild Helicopters
Tom Frey wrote: "JohnO" wrote in message oups.com... Hi, Can someone point me to any official accident statistics that would demonstrate the relative accident rates of various classes of certified and experimental helos? Specifically I would want to exclude any accidents that were pilot error or failure of maintenance. and only consider accidents where there was a design fault I'm interested to know how safe the design is on the various kit helos, in particular for Rotorway in the KISS turbine version. It concerns me that a lot of the luminaries of the kit helicopter world such as Schramm and Bedo have died in accidents, but I'm not sure if the reasons were faults in the aircraft or pilot error. Cheers, JohnO Do you mean something other than the NTSB records? http://www.ntsb.gov/ntsb/query.asp Tom Hi Tom, The link seems to be broken? |

Snip ---------- Do you mean something other than the NTSB records? http://www.ntsb.gov/ntsb/query.asp Tom Hi Tom, The link seems to be broken? Let's hope it's just down for modification or repair, because I can't get it to work now either. I accessed it from their aviation page at http://www.ntsb.gov/aviation/aviation.htm, and the top three search options on that page are now yeilding the same error. |

Dollars to donuts it was a maintenance or operator error, unless the site is hosted on Microsoft IIS in which case I'd suspect design failure. |

We know a guy who just finished a year of MedEvac flying in a 206L and had previous experience flying and instructin in homebuilt helicopters. He has returned to flying the homebuilt variety feeling that it is safer. This is one man's experience. Why did he feel it was safer? Was it because he did his own maintenance? |

JohnO: I think it was an exposure kind of thing. When he took a look at
engine reliabilty in turbines compared to his experience with experimental piston engines and coupled that with being able to pick your weather days flying experimentals vs take-it-as it comes as well as night flights over really nasty terrain and having a strong need to get there because of life saving situations; the flying would, I think, get a lot more hazardous than just flying an experimental helo. Hell, I really didn't like the night cross country I had to do for my helo add-on and that was good weather over the LA basin. Great horizon reference available. I can't imagine flying at night, into unknown weather, over whatever with trees, power lines etc. I would hear every bearing in the engine and transmission just hollering. -- Stuart Fields Experimental Helo magazine P.

I can imagine the urgency of a medivac that's bad enough to require a helicopter and with all the things you stated above would strain even the best pilot. One mistake, well, there's no room for 1 mistake. Unless he was flying with NVG's I would say he's as brave as they come. -- boB copter.six |
