The ownership trade-off

Extraordinary STOL and configuration flexibility, but it is slow, unpressurized and commercially complex to operate.

Cost picture at different usage

  • 40 hours/year: about €400k per year ( €10000 per flight hour all-in)
  • 80 hours/year: about €500k per year ( €6250 per flight hour all-in)
  • 120 hours/year: about €600k per year ( €5000 per flight hour all-in)
  • 180 hours/year: about €750k per year ( €4167 per flight hour all-in)

Older examples add calendar-driven maintenance: a 2011-built airframe is estimated at €533k per year at 80 hours. Condition, engine time remaining and avionics matter more than the year itself — price the aircraft in front of you, not the model.

Where it fits well

  • 182 kt cruise supports credible cross-country touring.
  • 989 nm advertised range creates a practical planning radius of about 663 nm with 4 occupants.
  • 1563 kg realistic payload proxy and 21 seats define the usable cabin mission.

Limitations to price honestly

  • Extraordinary STOL and configuration flexibility, but it is slow, unpressurized and commercially complex to operate.
  • €300k fixed annual planning base before flying a single hour.
  • Approximate 366 m take-off requirement must be checked against runway, surface, slope, temperature and loading.

Recommended missions

  • Family and small-group touring with a weight-and-balance check for every trip.
  • Short and medium regional trips, accepting fuel stops when conditions require.
  • Recreational, training or personal travel where operating efficiency is more important than airline-like speed.
