Can someone tell me what the overhaul intervals are for the following engines?
CFM56-3, -5, -7
I have some data which suggests that overhaul for the CFM56 is every 10,000 hours, but that sounds quite low to me and I'm also not sure whether the same interval would apply for the -3 and the -7 which as I understand it are rather different engines. If the interval is every 10,000 hours I guess that means that an engine for a big carrier like Southwest which must do 3,000 hours a year would go for overhaul in every 3-4 years, which strikes me as being too frequent.
Any insight would be much appreciated?
