- Proper loading is critical to maintain stability and control
Fuel Capacity and Usage
- Total fuel capacity: 30 gallons (113.6 liters)
- Usable fuel: 28 gallons (106 liters)
- Fuel consumption rate: Approximately 10-12 gallons per hour at cruise
Flight Maneuvering Limits
- Recommended maximum airspeed: 130 knots (150 mph)
- Stall speed in level flight: 50 knots (57 mph)
- Avoid steep turns and abrupt maneuvers to prevent loss of control
Environmental Limits
- Maximum operating altitude: 14,000 feet (4,267 meters) without supplemental oxygen
- Maximum temperature for operation: 30 degrees Celsius (86 degrees Fahrenheit)
Emergency Procedures
- Immediate actions required for engine failure or other emergencies
- Importance of regular emergency procedure training and familiarization
Maintenance Intervals
- Regular inspections: 100-hour and annual maintenance checks
- Importance of adhering to maintenance schedules to ensure airworthiness
Operational Restrictions
- No aerobatic maneuvers permitted
- Limitations on flying in severe weather conditions (e.g., thunderstorms, icing)
Pilot Requirements
- Must hold a minimum of a Private Pilot certification for rotorcraft
- Endorsements required for specific maneuvers and aircraft type
Safety Considerations
- Emphasis on pre-flight checks, including fuel, weight and balance, and systems checks
- Importance of staying within defined operational limits to ensure flight safety

Weight Limitations

Maximum takeoff weight is 2,500 lbs (1,134 kg).
Useful load is approximately 1,000 lbs (454 kg), varying with fuel and equipment.

Center of Gravity (CG) Limits

Forward CG limit is at 36.0 inches from the reference datum.
Aft CG limit is at 43.0 inches from the reference datum.
Proper loading is essential for maintaining helicopter stability and control.

Fuel Capacity and Usage

Total fuel capacity is 30 gallons (113.6 liters); usable fuel amount is 28 gallons (106 liters).
Fuel consumption ranges from 10 to 12 gallons per hour during cruise flight.

Flight Maneuvering Limits

Recommended maximum airspeed is 130 knots (150 mph).
Stall speed in level flight is 50 knots (57 mph).
Steep turns and abrupt maneuvers should be avoided to prevent loss of control.

Environmental Limits

Maximum operating altitude is 14,000 feet (4,267 meters) without supplemental oxygen.
Helicopter operational limit is set at a maximum temperature of 30 degrees Celsius (86 degrees Fahrenheit).

Emergency Procedures

Engine failure and other emergencies require immediate and specific actions.
Regular training and familiarization with emergency procedures are crucial for safety.

Maintenance Intervals

Inspections are mandatory every 100 hours and during an annual maintenance check.
Adhering to maintenance schedules is vital to ensuring aircraft airworthiness.

Operational Restrictions

Aerobatic maneuvers are strictly prohibited.
Limits exist regarding operations in severe weather conditions, including thunderstorms and icing.

Pilot Requirements

A minimum of a Private Pilot certification for rotorcraft is required.
Specific endorsements are necessary for certain maneuvers and the aircraft type.

Safety Considerations

Pre-flight checks must include assessments of fuel, weight and balance, and critical systems.
Remaining within defined operational limits is key to ensuring flight safety.
