Shoulder Harness & Belts

GAdams · #1 07-24-20, 11:55 AM

I'm trying to install Hooker Shoulder Harness and Belts in my 337D. Unless I want to get a DER involved at great expense it can't be done legally. I know the BAS system can be installed and Cessna has a kit for a single shoulder harness. SK337-55A2, which is available from Cessna. I'm going with the Cessna kit unless anyone has any ideas about the Hookers I already own.

I installed the Cessna kit on my B model. The kit included new shoulder and lap belts, for the front two seats, and the hardware to install it. My plane already had the threaded Holes for attachment in the airframe. It was easy to install. Well worth it...if you ever need it.

I am a BAS guy, installed in both of my aircraft. I like the 4 point system for safety, and they are comfortable to fly with. Can also undo the should harness in flight if you want. A little more work to install than Cessna (I believe), but not difficult to do over a weekend.

I have the BAS system and am very happy I took the time to install it when I did a refurb on the interior. I considered the Cessna kit but really glad I pursued the four point harness. I was concerned that they wouldn’t be comfortable in flight but I have never had to take them off for any flight. You could remove the uppers during flight but you won’t need too. Hooker Harness makes great belt system but I’m not doing aerobatics in my Skymaster. There is some talk about the concern of drilling through the forward spar for attachment but I think it is a proven system and am not concerned about the install. Go with the best system out there and for us it’s BAS. Protection is the best reason.

are there any shoulder belt systems for the rear occupants?

The middle seats can get shoulder harnesses form serial number 1194 onward. The rear seats can get them from serial number 1317 onward.

My parts manual shows that the middle seats take the same shoulder belt assembly as the pilot & copilot. The rear seats take a different one. The part number varies with color.

I'm considering the 3-point airbag system from Amsafe instead of the 4-point BAS system (which is really a 3-point with a split shoulder harness.)
