I have seen the results of poor attach points on a pietenpol that crashedfrom about 50 ft. high. The attach points were at the fuselage clusterwhere a longeron and diagonals come together behind the pilot's seat. I didnot use those points.Instead I ran a 1/8 cable to a plate in the tail end of the fuselage thatthe tail sping attaches to. the other end of the cable was brought forwardto a chromoly steel structure about a meter behind the pilot. protrudingabove the skin of the aircraft is a fitting that comes with a car baby seat(looks like and end of the seat belt). The shoulder harness is attachedhere. This way the shoulder harness is effective and will not put any unduecompression on your spine in the event of a mishap. Must add that althoughthe chromoly steel structure is screwed to the crossmember between the toplongerons, it's the 1/8 inch cable that will take all the stress to thestrong tail area.The lap belts are anchored by forming a steell strap around the bottomlongerons at and just behind the seat (pilot). The lap belt for thepassenger is anchored through the bottom of the fuselage at the ash woodcross member. The shoulder harness is merely clipped to the 1/8" crosingcables just behind the passenger's head. It works for me.Domenico Bellissimo-----Original Message-----
