Shoulder Harness

I have non-inertial reels for my shoulder harness, I installed them in 2011. It's fairly easy for me to remove the take-off flaps, but adding in the initial flaps for landing is more difficult. I handle this by having the shoulder harness loose enough while I am in the pattern, and when I have turned to final I include tightening the shoulder harness as part of the GUMPS check. If I need to do a go-around, it's easy for me to get the flaps down to take-off position at the right time, and when I am safely above the ground deal with the last bit of flaps.

I haven't ruled out the EZ-flap. My height probably helps somewhat.

Best money I've spent so far on Sid... and that's more than I care to add up... The EZ Flap handle can be reached without having to bury your head in the cockpit, and it's just by my right knee. My shoulder straps are snug all the time...

I was something of a purist myself, but realized I don't own a pristine classic, so anything I put in there from gauges to iPads that enhance safety and make life simpler, gets fitted. Tying one hand behind your back and poking yourself in the eye for the sake of historical accuracy is something I gave up fairly early on...

Does anyone have a drawing for the bracket used to install the BAS inertia reel shoulder harnesses? BAS will provide the drawing "if you decide to proceed," but I'd like to evaluate this a little further before plunking down $1,375. Thanks.

Please share your documents, great idea. I’m assuming the FAA doesn’t push back to hard installing shoulder harnesses.

I did mine on my 1939 Stinson HW75 by obtaining a complete set of Piper Warrior seat belts, shoulder belts, and retractors from an aircraft salvage, even the correct color to match my plane. I manufactured a clamping arrangement the the tubular framework for the retractors above and behind the headliner with re-inforced slits for the shoulder belts to come through the headliner. I modified the lapbelt attachment bolt sizes to attach to the existing lap belt attachment fixture. All of the work was done and approved by myself with my IA, and approved by the FAA on a Form 337. I presume that the tubular frame of the 108's is very similar to the HW75/105. The cost was minimal, only what I had to pay the salvage firm, and now I have modern seat belts, and retractable shoulder harness. No problem at all reaching the flap handle. I could supply copies of the 337 and various photos if anyone is interested. Let me know if I can help.

@gestionesaeroagricolanoresteyahoo-com  Damian, these are inertial reel harnesses from BAS installed in my 108-3.   I installed mine quite a few years ago.  Back then they provided an attachment kit which included a clamp (which was a section of 4130 steel tube cut down the middle) which was fastened to the overhead transverse steel tube.  Now they don't supply that attachment kit and you have to fabricate your own clamp.  They were pricey then and I'm sure very expensive now.

I'll add, when I teach, if you know your landing off runway, in the last seconds to release hands and feet from controls as this sudden impact often breaks limbs. Also, to throw up a cushion - perhaps back seat lower cushion to the windshield area. This has been used in the past with good results. The breaking of plexi often causes many bad things to the upper body and being protected is what it's about.  Lastly, in SE airplanes, we have a higher survival rate most likely due to lower energy upon impact. Look at light twin GA accident data and you'll see a higher fatality rate often due to higher energy impact. So land slow, controlled and protect yourself.

@gestionesaeroagricolanoresteyahoo-com  Damian, the seat belts and 4 point harness came with the inertial kit from BAS.  The belts and harnesses are manufactured by Amsafe.  I believe BAS can still provide you with the belts and harness, but you will have to fabricate the overhead clamp for the inertial reel.  Amsafe www.amsafeaviation.com (602) 850-2850.

I'm installing BAS Interia belts in my 108.   If anyone else is interested, I can supply the upper cross member mount per BAS drawings.  If anyone is interested just call 907-357-9323.   Mel

You uploaded the picture fine, it was a setting in the software I had to change. Should be all good now but here is a test to make sure….
