PLASTIC RIPCORDS

Recommended Posts

Plastic Martin Baker handles were banned here in the USA back in the late 70's early 80's cuz they would break in
two when they got old / cold, the cold was more of an issue if I remember correct.
I would not use a plastic martin baker on a rig today, I don't know of any others in use.

Actually there were two kinds of martin baker plastic handles. One was white and looked polypropylene, or some such thermoplastic. This ripcords were the ones known for breaking and leaving the small part in the elastic pocket. A friend had this happen and managed to find the cable and pull the reserve.

There also were fiber filled ripcords that were more tan or grey and looked like fiberglass. I don't know that these ever had a problem but often were removed from service along with other ones, "just cauz". I think I have a fiber filled one somewhere.

I remember the fiber-filled ones staying around a lot longer. Our DZ's Strong student rigs had SOS systems with fiber handles into the early 80's, and the thermoplastic MB's were history long before then.

My boyfriend demonstrated that breakage once with his main handle. Just whapped it on the ground by the cable and sure enough it broke.

There is nothing more dangerous than breaking a basic safety rule and getting away with it. It removes fear of the consequences and builds false confidence. (tbrown)

USPA doesn’t have and never has had the authority to ban the use of any component of a rig manufactured under a TSO.:P

But the FAA did issue 2 AD on plastic handles.

MarS' website describes it as: Release device-metallic handle - line - 2 needles.
Some of their photos show American-style D handles, while others show red plastic handles.
It is not clear from the photographs if the red plastic handles have an inner metal piece.

It has been 20+ years since any North American trusted a plastic reserve ripcord handle.

MarS Inc. does not hold an TSO of any kind in the US so the ues of their equipment here is moot.
