I just wonder that the engine times are. If the aircraft actually flew that much - 14 hours a day... the engines would be TBO'd in 5 months... and the aircraft would have had (20) 100hr's in that time.
It wouldn't suprised me if some mx is just pencil-whipped.
Next time you talk to them, just ask them what the aircraft Total Time, and engine times you are going to be flying.
