At $1.08 million for the U.S. model before typical options, the DA62 compares well with the competition, slotting in above the price of a new Piper Seneca V and below the Baron G58. What could give some buyers pause is the short engine overhaul interval, which at the moment is a mere 1,000 hours for the new Austro AE330s. Based on the Mercedes-Benz diesels in B-class automobiles, the engine is a proven design, and the 1,000-hour limitation is projected to be short-lived as Diamond gains experience with the aero engine. The company hopes to increase TBO to as high as 2,400 hours eventually. Other required engine maintenance, meanwhile, includes inspection of the generators at 300 hours, and replacement of the high-pressure fuel pump and inspection of the two-mass flywheel at 600 hours.
