"well there isnt any thing wrong with them" i have been using mmo for decades, the thing i like about mmo is that the engine starts better, saves batterys, starters. but thinking ill get longer life might be true, but like must people i trade before it wears out. ie most people trade cause they get tired of it
FAA requires aircraft to do Major Engine Overhauls at 2000 hours of running time.
Required overhaul (TBO 2000) is only for "for hire" aircraft. Also this overhaul is only a teardown, inspection, and re-assembly. Only out of spec parts are replaced, at a minimum.
