I had a accident I was going 45 - 50 mph .it was raining hard and roads were slippery hit a tree and neither airbags deployed.

Since it appears this was a single car accident in which you were the driver, I don't see where you have a cause of action against anybody. If you want to sue the car manufacturer because the airbags did not deploy, you would need to find an attorney who handles those kind of cases.
