I have a question for the rule makers at the DOI? When you changed the rules for an approved helmet. The DOI used a rule that the helmet will be a "Helmet" in current use or previously used by the US Military, because only the military can be trusted to test a helmet to be safe. Ok I have that understanding so far! However, The only helmets you can buy are civilian versions of the actual military helmet.
You have the Military version of the HGU 56P sold only by Capewell Aerial, and they can only sell to the US Army and the US Coast Guard. Then the SPH-4B, which was never sold to civilians, instead Gentex sold the SPH-5 which they also claimed to be the exact same helmet as the SPH-4B. Now this rule was because there is no testing standard for helmets, according to the DOI, so only the Military tested helmets would be aproved. Except the HGU 84, was a Marine Corp helmet that was never tested at USARRL, or anywhere else.
So how is it that Gibson and Barnes is allowed to sell the civilian version of the HGU56/P, the HGU 84 and the SPH-5 when in fact non of these helmets have ever been tested by the boys at Ft. Rucker? I read an article in "Airmed and Rescue" where Gibson and Barnes stated that the Commercial HGU-56 and the Military 56P are the same exact helmet except for color. And why is it that only Gibson and Barnes is the exclusive dealer for DOI approved Gentex helmets when none of the helmets they sell are Military grade helmets, but in fact "copies" of the real thing?
Did the DOI come up with this rule so Gibson and Barnes would not have any competition and the rest of us have to buy 20 plus year old designs? And lastly, how does someone buy a "Military Helmet" ? I thought that when the government paid you millions of dollars in R&D funds, that you can't sell that design to the civilian population? Isn't this how the SPH-5 came into the market over the SPH-4B?
Please explain since I am just a guy with a High school education!
