the cost savings amount to as much as a 20 percent of the overhaul price, a substantial savings.
CASA used to allow even commercial operators to go past TBO under specific circumstance up to around 200 hrs. I reckon for every 1% you went past the recommended TBO seemed to add 2% to the typical overhaul price. Various components that normally could be overhauled and reused went beyond limits and had to be replaced at greater cost. In short it was a false economy and depends greatly if its a fixed price overhaul or not and if continental are actually introducing technology that truly extends the component life.
