Harness Brackets

When I bought IH back in 1998, the aircraft was fitted with a 4-point harness where the shoulder straps were attached to the cross tube that supports the top a the seat sling. This was totally unacceptable as in a crash this can lead to compression of the spine and severe back injuries. Later I moved the attachment position to one of the top cross members further back in the fuselage using a U-bracket around the cross tube. This was better but not perfect, so now I'm taking the oppotunity to weld some permanent brackets into the airframe.

Two brackets were cut from .090" 4130 steel plate and drilled to take an AN4 bolt. After welding, the holes will be reamed out to size.
