What kind of maintenance requirements do Part 121 and 135 aircraft have to have?

Asked by: 4248 views , ,
FAA Regulations

I know that aircraft used for flight instruction have to have a 100 hour inspection and all general aviation aircraft have to have an annual inspection, what kind of maintenance requirements do commercial airliner's have to have?

    Did you happen to spend a few minutes looking at Part 121 or 135? The contents section has a sub-part called maintenance.

    Click the blue link for 110-199. There you will find parts 121 and 135.
