Over the years, people have made attempts to install a shoulder harness arrangement that, frankly, scares me. The shoulder harnesses are attached to the upper cross member that holds the vertical posts of the seats. This attach point is well below the level of the shoulders. This is quite dangerous. Should there be, even a slight forward impact, the harnesses will compress the spine so that an otherwise minor incident could become a major, possibly debilitating, injury.
We need to get the shoulder harness attach points to a point no more than 3 degrees below the level of the shoulder to about 12 degrees above, per the 43.13-1b. I have designed, and received field approval, for a shoulder harness attachment that is riveted to the inside of the top of the fuselage. If you would like to install safer shoulder harness attachments into your plane, let me know. I can send you all the paperwork you will need to build and get approval to install them into your OTW.
can you send plans to craig.wadsworth@nationalwarplanemuseum.com?
we are operating OTW serial number 61 and consider shoulder harnesses a must add…Thanks,
Craig
