inspection of Airplanes

The airplane that went in off the Florida coast - an old seaplane reminds me of something is wrong today. They have a system of inpections that in my opinion really does not work. I remember when I worked for NWA - they had old DC3s amd every so often they actually used to overhaul the planes and literally made new planes out of them. Today to get by cheaper- they come up with a system of inspection that reworked certain area. After so many flying hours there should be a an actual overhaul system to remake then into a new airplane if they want to keep flying old airplanes. This reminds me of the crack up of firefighting airplanes that drop water and chemicals on the forest fires. I believe that several of those planes have been lost due to the age and maintenance of the planes. I do not believe there is a cheap way of doing maintenance that honestly works. I believe that 20 people lost their lives on the seaplane that went down. From what I read the wing came off from cracks in the wing that was not spotted. Eyes can not spot everything. This also reminds me of a company that I worked for - in repairing electronic equipment- there comes a time old planes,etc i do not believe cannot be reworked on a basis of inspection to be useable. Cheap labor is not the answer eithor. There is a growing problem in this country in that the CEO get huge wages,bonuses etc yet the trend is lower wages on needed skilled workers. We have a one party government in Washington that is trying to push that program. People please wake up.
