@whirlcool:
I think you are talking about the General Aviation Revitalization Act.
While there were a spate of lawsuits from parties with an interest in small airplane crashes in the late 1970s and early 1980s, it's useful to think why that happened. People that bought small aircraft tended to be financially successful, which gave them the ability to buy small aircraft in the first place. Successful entrepreneurs tend to be risk-takers in their business dealings, and spread out their success into other endeavors. Type "A" personalities, if you will.
The genesis for the legislation that absolved light aircraft manufacturers from liability came from 2 things:
1. The recession of the late 1970s/early 1980s that pummeled the small airplane business. As a result, the market value of Cessna dropped dramatically. The recession of the late 1970s/early 1980s really hurt their business jet business. It hit their small airplane business, worse than the biz jet business but the core value of Cessna was the biz jet worth.
2. General Dynamics purchase of Cessna in 1986. General Dynamics had strong political connections (being a gigantic defense contractor that made everything from fighters to nuclear submarines) and used those connections to their advantage. They were buying Cessna for their undervalued business jet business, not their little airplane business.
Business jets are flown by professional pilots for the most part, and there are usually 2 crew members flying them. Not much liability attached to that.
General Dynamics wanted to buy the plum part of Cessna, and not have the little airplane part hurt their bottom line. Hence, the GARA act. Not drunk pilots or distraught wives.
But, as the saying goes, "everything old is new again". General Dynamics eventually sold Cessna to Textron - and Textron owns Lycoming, which makes piston engines for small airplanes, Bell Helicopter Company, and EZ-Go Golf Cart company.
So, things are never as simple as they seem.
If you're eyeballs aren't totally worn out by now, I can tell you about how we ended up with Allied-Signal, which managed everything from oil wells to nuclear warhead production. It's a fascinating story of American business, where the expected outcome was where Signal Oil would take over Allied Chemical...
