Hourly Engine Reserves for DA42

Posted on April 23, 2015

There are three configurations of currently supported DA42 engines:

  • CD135 with 600 hour clutches
  • CD135 with 2 mass flywheel
  • Austro AE300

The Austro engine is heavier, more powerful, more expensive (installed in an airplane), longer lived, and less expensive to operate.  The CD135 with 2 mass flywheel is approximately 15- 20% less expensive to operate, since it lacks the clutch replacement and offers the extension of gearbox replacement from 300 to 600 hours.

The figures below are estimates only, and they will vary with life extension, exchange rate fluctuation, shop experience, manufacturer price changes, etc.  We believe these are an accurate estimate of the hourly reserve costs, but check with your shop and the manufacturers to confirm a firm cost.  These figures reflect DA42 applications and may be very different for the DA40.

With current (4/20/15) exchange rates and requirements and $75 labor:

Two Engines $Reserve Hourly
CD135 Clutch $102.44
CD135 2Mass Flywheel $87.39
AE300 170HP $48.45

2 responses to “Hourly Engine Reserves for DA42”

  1. Rob Freeman says:

    Your engine reserve estimates are an excellent tool for folks looking at a DA42. Thanks so much. With Centurion just announcing an increase in the TBR of the engine to 2,100 hrs. and a longer gearbox and timing chain service of 1,200 hrs., the hourly reserves will change for the CD 135. Do you concur and, if so, can you revise your reserve estimates? Thanks very much.

      Yes, we will be recalculating all of that once there is clarity as to what the applicability of the TBR extension is.
