HELIHoMe history Robinson R22

HELIHoMe history 📜 😜 : The Robinson R22 is a two-bladed, single-engine light utility helicoptermanufactured by Robinson Helicopter Company. The two-seat R22 was designed in 1973 by Frank Robinsonand has been in production since 1979. 📰 The majority of flight testing was performed at Zamperini Field in Torrance, California. Flight testing and certification was performed in the late 1970s by test pilot Joseph John "Tym" Tymczyszyn and the R22 received FAA certification in March 1979. Due to relatively low acquisition and operating costs, the R22 has been popular as a primary rotorcraft trainer around the world and as a livestock management tool on large ranches in North Americaand cattle stations in Australia. The R22 has a very low inertia rotor system and the control inputs are operated directly by push rods with no hydraulic assistance. Thus, the flight controls are very sensitive and require a light touch to avoid over correcting. A student that masters an R22 generally does not have a problem transitioning to a heavier helicopter. Due to the issues relating to a low inertia rotor system and a teetering main rotor, operation by any pilot in the United States of the Robinson R22 or Robinson R44 requires a special endorsement by a certified flight instructor. Tip weights were added to increase rotor inertia, but the small rotor limits weight. 📋 The R22 has a suggested retail price of $285,000 (ex factory price, USA) and the value on the second hand market is dependent on component time in service. Operating cost, per the factory, including insurance, reserve for overhaul, and direct operating cost (fuel, oil, inspections, unscheduled maintenance) is US$143.59/hr. A full overhaul of major components is required at 2200 hours (or 12 years, whichever comes first), which is sometimes known as "Timex" Depreciation on a Robinson R22 is negligible, as freshly overhauled R22s typically sell for more than the original cost. However, a provision per flown hour must be made for a "reserve for overhaul" cost, currently estimated at US$60.33 per hour. (Total approximate overhaul cost: ~$60 x 2200 Hours = ~US$132,700) The Robinson price list is updated in February each year. 📚 R22 Initial production version powered by a Lycoming O-320-A2B or A2C piston engine.
