Operating limits

Fuel is 92 octane minimum auto fuel or 100LL. Maximum airspeed is 115 mph at sea level; reduce it 2 mph for each 1000 ft of density altitude. Limits are 75 mph in turbulent air and 20 mph sideways or rearwards. Out-of-ground-effect hovers are prohibited for Exec pilots under 150 hours.

What to inspect

The maintenance manual sets 100 HR airframe inspections and a 2000 HR recommended change-out. About 80% of aircraft weight goes through the rear gear, so check it closely. Keep the engine mount rubber (50 HR inspection) free of oil and grease. Replace a skid tube if a flat wear area exceeds 1/2 inch wide. Tail rotor belts have a 250 HR change-out and the blades 500 HR.

Weight and balance

Empty weight is 925 lbs, maximum takeoff weight is 1500 lbs, and maximum variable load (pilot, passenger, fuel, ballast) is 525 lbs. Solo flight needs ballast on the front passenger skid. Dual flight needs ballast on the rear mount tube. A static hang test, done with no fuel and results within 1/2 degree, is required before first flight.

Safety notes

  • Engine failure above 500 feet AGL: enter autorotation at about 65 mph and hold 100% rotor RPM (520 RPM).
  • Do not attempt an air restart until a safe autorotation is established.
  • Limit engine operation between 2500 and 3000 RPM during run up and run down because of main drive belt resonance.
