What is clear is that aircraft that have had no corrosion control program and live outside will be very expensive to put through the SID's and I have no doubt that these are the aircraft that Cessna want to take out of the air.
Maybe, but don't condemn aircraft just because they live outside.
Who needs a corrosion control program?? A good engineer giving an aircraft a good, proper, annual and then a good treatment of ACF50 will keep these aircraft going.
Corrosion control program on a Cessna 150? You sound as if you have been brain-washed by the EASA drones...... It's a basic 2 seat aircraft for goodness sake, not a PC12NG.
Get what you pay for? Well I see plenty of hour-builders queuing up to fly tatty aircraft for half of what the good schools are charging. And it's strange how the engine oil on these tatty aircraft is black immediately after an annual inspection???
