I want to put a shoulder harness in my piet. The crossmember behind thepilot is low and I've heard that there are fears of spinal compressioninjuries in case of impact... which kind of makes sense. I'm thinkingof reinforcing the turtle deck former behind the pilot and running theharness out of the very top of that and then running a cable back in thefuselage to some solid cluster or even to the tailskid/keel area. Passenger harness can obviously go to the cabanes so that's easy. Whathave you guys done or seen that works. My problem also is that Ipurchased a project and the fuselage is already covered but the guy madeno provisions for seat belts of any kind so I've got to go in andretrofit something.thoughts??Douwe Blumbergdouweblumberg(at)earthlink.net I want to put a shoulder harness in mypiet.The crossmember behind the pilot is low and I've heard that there arefears ofspinal compression injuries in case of impact... which kind of makessense.

I ran a 3/32" cable from an eye bolt with a large washer, through the tail post, to the fittings on the end of the shoulder harness. This put the harness above the turtle deck, so I built a head rest out of fiberglass, to enclose it. It's not quite straight back, but angled down just a few degrees. As for the passenger, Gene makes a good poing about the top of the cabane struts, but I don't see any other way to terminate them, and maintain the correct angle. I'm planning on terminating the passenger harness to the top ofthe cabane struts, unless someone has a better idea.Chuck G.________________________________________________________________________________

Thanks for all the good input on shoulder harness. I wasn't thinking ofrunning them to the top of the cabanes, I thought tying into thefittings down by the top longeron might work.

William, a picture from you would also be very helpful. I am very interested in the Brit's method. I'm to the point of adding this harness, so as to give others the 'Pietenpol Experience'.Chuck Gantzertuesday evening, closed traffic, dozen landings, two on hard surface narrow runway - lovin' it !!!________________________________________________________________________________Date: Fri, 10 Oct 2003 00:42:59 -0500
