Powered flight has been going for just over 100 years and the O-200 has been in service for almost half this period.
If you think it's a good choice for a new aircraft design then it shows bloody pathetic thinking where innovation has been destroyed by fear of Public Liability. I don't care how real this is - if it stifles development then we've got into a very sad state in this industry. The rest of the transport world must be having a really good laugh at us.
