Under what circumstances? That's a pretty bold statement that can be shot full of holes pretty quickly. (Not directed at you Ted)
I'd like to see some real numbers on fatal RV accidents, and what percentage of those could've been survivable with these. I'm betting not many...

GA Statistics
Those were GA statistics from the Safety Foundation.
All RV's that I know of have shoulder harness' so at least it's the higher end survival rate. That being said, it's all relative as some crashes are not survivable at all.

Ted,
I was at a similar seminar on Monday evening but did not have the chance to talk with the Amsafe people. I'm wondering if they gave you any indication of the pricing on these? I cannot find anything on the web.
thanks,
greg

I don't remember where I heard it but I believe it was $1,000.00 each.
If you go to CubCrafters website they show them as an option on their planes for $3,990.00 installed. That's for pilot and co-pilot.
Maybe Craig from Skyview Aviation can chime in here as he is listed as a Service Center contact for AmSafe.

AmSafe Seatbelt Airbags
Hi Guys,
Please feel free to contact me at any time if you have questions on seatbelt airbags rheitzman@amsafe.com
Some items to consider
Please visit www.gaairbags.com to review a large amount of information.
I don't want anyone to bombard me with questions on when will the systems be released, but we are looking at the Van's RV series aircraft as the first large scale development for the experimental market. It's no secret but I cannot give you all a set date on when the kits will be completed.
Pricing is NOT set, but the range you guys can expect will be between $3,000-$4,500 for TWO systems.
Distribution has not been set. We are looking at all options.
On average it takes 9+ g's of deceleration force at a .45 second duration to set off the system. The g sensor in the EMA (Electronics Module Assembly) is looking at force and time. The EMA has a onboard battery pack (7 years on battery, 14 year total like EMA) and when the force/time is met sends the voltage to the inflator bottle (7000PSI helium argon compressed gas, 10 year life span) which pops a cap, shatters the diaphragm, releasing the gas up the inflator hose (10kPSI fire hose 1/2 diameter) and the bag (for the RV will be contained in the shoulder harness) splits a tear seam and deploys to the front of the pilot/passenger. Stays up for about 3-5 seconds and then self deflates.
That captured most of the questions. They are effective in preventing head and torso trauma which is the number one injury/fatality in ALL GA aircraft accidents. 80% of all GA aircraft accidents happen in the vicinity of the airport and at speeds that are survivable. We test our systems up to a 26g load at our sled test facility in Phoenix.
Thank you for all your positive comments. The NTSB report was great but I must also clarify they are NOT mandating the FAA to do anything. They are reporting on the findings and showing that shoulder harnesses and seatbelt airbags increase the chance of survival by a factor of 70% over just having lap belts.

Hi Rich,
Thanks for the info. I'll add a couple of questions.
How much additional weight (above a "normal" shoulder harness set-up)?
How much space does the system add (control module, inflation bottle)?
Thanks

That's funny...Not for Aircraft???
I was under the impression that airbags were originally designed to reduce fatalities in Army Helicopter accidents. When a 'copter hits the ground and falls over, all Heck breaks loose!!
Automobile airbags are just a simple adaptation to the complex controls used in the aviation version?
Anyway, the idea of the 'bag' being projected away from your face toward the accident by a controlled release of nitrogen seems much wiser than a pyrotechnic device aimed at your face.
These have potential, and the price keeps getting better, even as the product improves. Kinda like computers. (Moore's law)
I'm never in favor of government mandates, get the Gov't in it and progress stops, yet price stays high.
Auto, Airplane and other power sport equipment manufacturers should (and do) advertise safety feature to attract buyers. That's the way I want it.
The Wife would want this added right quick!!

Airbag system weight
On average the system weighs about 6 pounds total for two seat placements. (Give or take about a pound depending on aircraft configuration).
