What about the CFM56 Tech Insertion ?
It is said that the fuel consumption is reduced by 1%, the reliability is better with a bigger EGT margin.
But what are the facts in real life ? Is the fuel consumption 'realy' lower than a 'classic' CFM56
?
Nevertheless, I am convinced that the maintenance cost are lower due to a better management of the LLP : the life limit of the first limiter is higher.
