A Sikorsky S-58T costs approximately $434k (€402k) to $519k (€481k) to buy at 1970 market values. Owning one and flying 80 hours a year costs roughly $370k (€343k) annually, about $4,625 (€4,283) per flight hour all-in, made up of a $32k (€30k) fixed annual base plus $2,668 (€2,470) per hour flown. Over five years, purchase and operating costs total around $2.32m (€2.15m) before financing, depreciation and tax.

What drives the real price?
Airframe and engine time, maintenance history, damage history, avionics, equipment, geography and tax treatment can move a real transaction well outside a model-level estimate. A cheaper example with deferred maintenance can be the more expensive aircraft after the first annual inspection.
What is included?
PlaneFit combines an annual fixed-cost base with a direct hourly estimate. The result is intended for comparing aircraft and testing utilisation scenarios. It is not a maintenance programme quote, insurance quote or pre-buy assessment.
Insurance sits inside the fixed annual base rather than alongside it. To see how that single line breaks down by pilot experience and model year, read the Sikorsky S-58T insurance cost guide.
The central ownership compromise
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.
