Al Downs Posted July 20, 2019 Report Share Posted July 20, 2019 We have three choices of when to do maintenance. Calender, hobbs and tach. Elt batteries, parachute and rocket are some of the calendar items. Oil change and other Rotax items are by hobbs. What about airframe 100 hr? Is that by tach or hobbs? Are the gearbox and prop by tach or hobbs? Not much of a difference for private planes but in a flight school it does make a difference. For example the difference between hobbs and tach time is significant when talking about the porp. Quote Link to comment Share on other sites More sharing options...
Anticept Posted July 26, 2019 Report Share Posted July 26, 2019 Record all total time by tach in the US. You're devaluing your aircraft excessively by tracking anything by hobbs. You can still maintain by hobbs as recommended by manufacturers as long as you don't overshoot the 100hr total time (unlikely). I personally maintain by hobbs but TIS is tracked by tach.
