The ownership trade-off

The S-58T combines 18-seat helicopter capability with about 220 NM reported range and about 110 kt reported cruise, while payload, runway and operating-cost figures remain indicative and should be verified for the specific aircraft before making a decision.

Cost picture at different usage

40 hours/year: about €229k per year ( €5720 per flight hour all-in)
80 hours/year: about €328k per year ( €4095 per flight hour all-in)
120 hours/year: about €426k per year ( €3553 per flight hour all-in)
180 hours/year: about €575k per year ( €3192 per flight hour all-in)

Older examples add calendar-driven maintenance: a 2011-built airframe is estimated at €240k per year at 80 hours. Condition, engine time remaining and avionics matter more than the year itself, so price the aircraft in front of you, not the model.

Where it fits well

110 kt cruise supports efficient local and regional flying.
220 nm advertised range creates a practical planning radius of about 147 nm with 4 occupants.
1440 kg realistic payload proxy and 18 seats define the usable cabin mission.

Limitations to price honestly

The S-58T combines 18-seat helicopter capability with about 220 NM reported range and about 110 kt reported cruise, while payload, runway and operating-cost figures remain indicative and should be verified for the specific aircraft before making a decision.
€30k fixed annual planning base before flying a single hour.
Component life and mission-specific landing permissions dominate real-world utility.

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.
