What the Cessna 650 Citation III is

The Cessna 650 Citation III is a twin-engine business jet built to carry six to eight passengers over long distances at high speed. Cessna produced it from 1979 to 1989, and many remain in active use today. The aircraft cruises at around 460 miles per hour and can fly nonstop for roughly 2,000 miles, making it suitable for cross-country trips without refueling stops.

The Citation III was designed as a step up from Cessna's earlier Citation models. It has a pressurized cabin, meaning passengers can fly at altitudes above 25,000 feet without experiencing the discomfort of thin air. The jet requires a crew of two pilots and can operate from smaller airports than larger business jets, though it still needs a runway of at least 5,000 feet.

Key Takeaways

  • The Citation III carries six to eight passengers and cruises at 460 mph, making it a mid-size business jet for trips up to 2,000 miles without refueling.
  • Two Garrett turbofan engines power the aircraft, and the pressurized cabin allows flight at altitudes above 25,000 feet.
  • Operating costs run between $3,000 and $5,000 per flight hour, depending on fuel prices, maintenance, and crew expenses.
  • The jet requires two pilots and a runway of at least 5,000 feet, but can use smaller airports than larger business aircraft.
  • Used Citation III aircraft typically sell for $2 million to $4 million, depending on age, condition, and total flight hours.

Engines and Performance Specifications

Two Garrett TFE731-3B-100S turbofan engines power the Citation III. Each engine produces 3,650 pounds of thrust, giving the aircraft a combined power output that allows it to climb quickly and maintain high cruise speeds. The engines are fuel-efficient for their size, which helps keep operating costs reasonable compared to larger business jets.

The aircraft reaches a maximum altitude of 43,000 feet, though typical cruise altitude is between 35,000 and 41,000 feet. At cruise speed, the Citation III burns roughly 250 gallons of fuel per hour. The jet carries 6,000 pounds of fuel internally, which translates to a maximum range of approximately 2,040 nautical miles with reserve fuel for safety.

Takeoff distance from sea level is around 5,000 feet on a standard day, and landing distance is approximately 2,500 feet. These numbers change with temperature, altitude, and aircraft weight, but they show why the Citation III can use regional airports that larger jets cannot access.

Cabin Layout and Passenger Comfort

The pressurized cabin measures 43 feet long and 4 feet 9 inches wide, creating a narrow but functional space for passengers. The standard configuration seats six to eight people, depending on whether the aircraft includes a galley and lavatory. Most Citation III jets have a small galley for beverages and light snacks, and a single-occupant lavatory toward the rear.

The cabin is heated and air-conditioned, and windows along the fuselage provide natural light. Noise levels are moderate for a business jet of this era — not as quiet as newer aircraft, but acceptable for most passengers on flights under four hours. The pressurization system maintains cabin altitude at roughly 8,000 feet even when the aircraft flies at 43,000 feet, reducing passenger fatigue on longer trips.

Operating Costs and Ownership Expenses

Hourly operating costs for a Citation III typically range from $3,000 to $5,000 per flight hour, though this varies significantly based on fuel prices, maintenance needs, and crew salaries in your region. Fuel alone accounts for roughly $1,500 to $2,000 per hour. Crew costs add another $800 to $1,200 per hour if you employ full-time pilots, or less if you hire on a per-flight basis.

Annual fixed costs include hangar rent (typically $500 to $1,500 per month), insurance ($15,000 to $30,000 per year), and scheduled maintenance. The Citation III requires a major inspection every 2,000 flight hours, which can cost $50,000 to $100,000 depending on what repairs are needed. Engine overhauls, which occur every 3,500 to 5,000 hours, run $400,000 to $600,000 per engine.

Many owners choose to charter their aircraft when not in use to offset these costs. Charter rates for a Citation III typically range from $4,000 to $6,000 per flight hour, which can help cover operating expenses if the aircraft is chartered 200 to 300 hours per year.

Maintenance and Inspection Requirements

The Citation III follows Federal Aviation Administration (FAA) maintenance schedules that require inspections at regular intervals. A 100-hour inspection is required every 100 flight hours, and an annual inspection is mandatory once per calendar year regardless of flight time. These routine inspections typically cost $2,000 to $5,000 and check systems, fluid levels, and wear on components.

Beyond routine inspections, the aircraft requires a C-check every 2,000 flight hours, which is a comprehensive examination of the airframe, engines, and systems. This inspection can take two to four weeks and costs $50,000 to $100,000. Engine overhauls are also mandatory after a set number of hours, and avionics systems may need upgrades to remain compliant with modern air traffic control requirements.

Owners should budget for unexpected repairs, as older aircraft sometimes develop issues that were not apparent during routine inspections. Setting aside $500 to $1,000 per flight hour for maintenance reserves is a common practice among Citation III operators.

Buying a Used Citation III

Used Citation III aircraft on the market today typically have between 10,000 and 20,000 total flight hours and sell for $2 million to $4 million, depending on condition, age, and maintenance history. Aircraft with lower flight hours and recent major inspections command higher prices. The oldest Citation III aircraft are now over 40 years old, so buyers should expect to pay less for these but should also budget for more frequent maintenance.

When evaluating a used Citation III, request the aircraft's maintenance logs and engine overhaul records to understand what work has been completed. Have a pre-purchase inspection performed by an independent Citation III specialist, which typically costs $5,000 to $10,000 but can reveal hidden problems. Check whether the avionics have been updated to meet current navigation and communication standards, as older systems may require expensive upgrades.

Financing options for business aircraft include traditional aircraft loans from specialized lenders, which typically require 20 to 30 percent down and charge interest rates based on the aircraft's age and condition. Some owners also consider fractional ownership programs, where multiple parties share the cost and use of an aircraft, though this option is less common for older models like the Citation III.

Pilot Requirements and Training

Operating a Citation III requires a commercial pilot license with a multi-engine rating and a type rating specific to the Citation III. The type rating is a certification that proves a pilot has trained on this specific aircraft model and understands its systems and procedures. Training typically takes 20 to 30 hours of flight time plus ground school, and costs $8,000 to $15,000 per pilot.

Pilots must also maintain a current medical certificate and log a minimum number of flight hours to remain current. Most operators require pilots to complete recurrent training every 12 months, which includes simulator time and classroom instruction. This ongoing training costs $3,000 to $5,000 per pilot per year and is essential for safe operation.

Frequently Asked Questions

How far can a Citation III fly on a single tank of fuel?

The Citation III has a maximum range of approximately 2,040 nautical miles with reserve fuel. In practice, most operators plan trips of 1,500 to 1,800 nautical miles to may support adequate reserves for weather delays or alternate airports. Actual range depends on aircraft weight, weather conditions, and cruise altitude.

Can a Citation III land at small regional airports?

Yes. The Citation III requires a runway of at least 5,000 feet, which is available at most regional airports. Larger business jets often need 6,000 to 7,000 feet, so the Citation III can access more airports. However, it cannot use very small airstrips designed for single-engine aircraft.

What is the difference between a Citation III and a Citation X?

The Citation X is a newer, faster, and larger aircraft that cruises at 500+ mph and carries more passengers. The Citation III is slower and smaller but costs significantly less to buy and operate. The Citation X entered production in 1996, while Citation III production ended in 1989.

How many crew members does a Citation III need?

The Citation III requires two pilots. Some operators also employ a flight attendant for passenger service on longer flights, but this is optional. The aircraft does not require a flight engineer or navigator.

What is the typical lifespan of a Citation III?

With proper maintenance, a Citation III can remain airworthy for 40+ years. The oldest examples are now in their mid-40s and still flying. Lifespan depends on maintenance quality, flight hours, and whether major components like engines have been overhauled or replaced.
