PlaneFox tracks 2 Schweizer 333 / S-333 aircraft for sale and re-reads every one of them from the broker and dealer sites it watches, so the figures below move when the market moves. Every number on this page is measured from those live listings, not taken from a published price guide.
A Schweizer 333 / S-333 flies about 310 nm, roughly 574 km, which is about 2 h 57 min in still air at typical cruise.
A Schweizer 333 / S-333 costs about EUR 9,651 a month to run, or about EUR 772 for every flight hour when it is flown 150 hours a year.
The Schweizer 333 / S-333 is a light, single engine turbine helicopter produced by Schweizer Aircraft, later under Sikorsky ownership after Sikorsky acquired Schweizer in 2004. It evolved from the Schweizer 330 series, with refinements to the rotor system, airframe, and cabin intended to improve payload, handling, and utility. The type was certified in the late 1990s and produced in limited numbers into the 2000s.
Its role is the compact utility and training market: flight schools, private owners, patrol operators, survey work, and light commercial missions. It matters because it offers turbine reliability and simple systems in a relatively small helicopter, while retaining the familiar Schweizer layout and handling lineage.
The Schweizer 333 / S-333 is powered by a Rolls-Royce 250-C20W turboshaft engine, commonly rated at 420 shp for takeoff, with power limits set for the installation. Typical published figures include a cruise speed around 100 knots, a maximum cruise speed near 109 knots, and a range of about 320 nautical miles, depending on equipment, loading, fuel, and operating conditions.
Maximum gross weight is approximately 2,550 lb, with useful load commonly quoted around 1,100 to 1,150 lb. Service ceiling is listed at about 13,000 feet. Buyers should confirm the exact weight and performance data for an individual aircraft, since installed equipment, optional kits, and maintenance history can materially affect empty weight and mission capability.
The cabin is arranged for up to four occupants, typically one pilot and three passengers, with wide visibility and a straightforward cockpit suited to training and utility operations. The compact cabin is not comparable to larger executive helicopters, but it is practical for short range transport, instruction, inspection, and aerial work.
Avionics in used Schweizer 333 / S-333 helicopters vary widely. Many aircraft were delivered with conventional analog flight instruments and standard VHF communication, navigation, transponder, and intercom equipment. Garmin GPS, modern audio panels, ADS-B equipment, and digital engine monitoring may be found as retrofits, but integrated suites such as Garmin Perspective or G1000 are not typical factory features for this model.
Used-market evaluation should focus on total time, component life status, engine records, hot section and overhaul history, rotor blade condition, gearbox records, corrosion inspection, and compliance with service bulletins and airworthiness directives. Parts support and shop familiarity are important considerations because the fleet is relatively small.
Common buyer interest centers on aircraft with updated avionics, clean maintenance history, low component time, and documented corporate, training, or private use. The Schweizer 333 / S-333 usually positions below larger four seat turbine helicopters in acquisition cost, while offering more capability than piston trainers. Its value depends heavily on remaining component life and the quality of records.
