Inspired by the gun thread…
As I understand it, U.S. aircraft manufacturers were until fairly recently (the last 10 or 15 years or so) liable for ‘defects’ in every aircraft they’d ever built. Making up an example off the top of my head: Suppose a certain anti-corrosion substance is used on all aircraft made since 1980, and that this anti-corrosion substance was not available before that time. Suppose Cessna or Piper or whoever originally sold an airplane in 1940 that was either not treated with an anti-corrsion compound (because nobody considered it necessary) or with a compound inferior to the ‘newest and best’. In 1985 someone flies this 45-year-old airplane and corrosion that had gone completely undetected in 35 Annual Inspections (or who-knows-how-many 100-hour inspections) causes a structural failure that results in fatal injuries to the occupants. IIRC, the manufacturer could be held liable for selling a ‘defective’ product even though the corrsion protection that would have prevented the crash was not available when the aircraft was built.
I have heard it said (sorry, no cite) that half the cost of a new aircraft was the insurance premium. With the increase in lawsuits in the early-1980s, and the large awards given to survivors, ‘The Big Three’ simply stopped building airplanes. (Or rather, they curtailed production significantly.) At the end of the '70s there were 15,000 new General Aviation airplanes being made every year. In the '80s 2,000 new airplanes was considered ‘good’. Cessna stopped building single-engine piston airplanes for a while.
If I am incorrect in my premise, I stand ready to be corrected and drop the question.
Ten or fifteen years ago (I don’t remember when) Congress finally put limits to the amount of time an aircraft manufacturer could be held liable for ‘manufacturing defects’. Now the manufacturers are only liable for 18 years. Cessna started building light aircraft again, and now we have new manufacturers coming out with designs that rival the dinosaurs that are still being made. I think this legislation was a good thing.
But does it go far enough? How many car makers are liable for their products for 18 years? My father was critically injured in a car without airbags, even though airbags were available when the car was made. (Though not available on that car.) I’d have been laughed out of court if I brought a lawsuit against a car company for not providing airbags when they were not yet required equipment. Why should an airplane company be responsible for 18 years? Heck, the Cessna 172 is 50 years old. The engine designs are very similar to how they were in the 1930s.
If Congress were to consider a law that limits liability to 2,500 flying hours (Lycoming engines typically have 2,000 hour TBO, and many aircraft would have had 25 100-hour inspections) or five years (which would mean that the aircraft would have had five annuals), whichever comes first, would you support the law? If not, then why not?
