Introduction to Buying a King Air 300
This guide is for companies and individuals considering the acquisition of a King Air 300. You will find key information to inform your decision.

The goal is to provide you with a solid foundation to successfully complete your acquisition project.
King Air 300 Market & Budget - CapEx
The Beechcraft King Air 300 is no longer produced new. The market is therefore exclusively focused on pre-owned aircraft.
Acquisition Price
| Market Status | Price Range (USD) | Examples |
|---|
| Pre-owned (2024) | $945,000 - $3,500,000 | In 2024, a standard King Air 300 trades between $945,000 and $1,155,000. Some very well-equipped or modernized models, such as those with Blackhawk conversions, can reach up to $3.5 million. For example, a 1987 King Air 300, which had a new price of $2.967 million, resells for approximately $1.3 million. |
Availability and Transaction Duration
Availability varies, but the pre-owned King Air 300 market is active. An average transaction time is 4 to 12 weeks, including pre-purchase inspection, negotiation, and administrative procedures.
Residual Value
The residual value of a King Air 300 depends heavily on its age, condition, and modernizations.
A 1987 King Air 300, for example, retains approximately 44% of its original value. Conversely, a newer aircraft, perfectly maintained and with up-to-date avionics, will see its value better preserved in the long term.
Estimated Initial Budget (excluding operating costs)
For the acquisition of a pre-owned King Air 300, plan an initial budget of $1 million to $3.8 million USD. This amount includes the aircraft’s purchase price and a provision for initial ancillary costs (inspection, transfer of ownership, initial insurance).
King Air 300 Operating Costs (OpEx)
The operating costs of a King Air 300 are divided into fixed and variable charges. Rigorous management is essential to optimize this investment.
Annual Fixed Costs
These costs are relatively constant, regardless of the number of flight hours. They include:
- Hangar: Rental of a secure parking space.
- Insurance: Coverage for the aircraft, civil liability, and passengers.
- Crew: Pilots’ salaries and, sometimes, a dedicated mechanic.
- Subscriptions: Updates for navigation databases and software.
- Recurrent Training: Maintaining pilot qualifications.
Annual Variable Costs
These costs fluctuate directly with the aircraft’s usage:
- Fuel: The largest expense item, impacted by the price of Jet A-1.
- Maintenance: Regular inspections, parts replacements, unforeseen repairs.
- Fees: Landing, takeoff, and air navigation taxes.
- Oils and Fluids: Consumables necessary for the proper functioning of engines and systems.
Major Maintenance Milestones
The King Air 300 is subject to a rigorous maintenance program including periodic inspections:
- Hourly Inspections: Often every 200 flight hours.
- Calendar Inspections: Every 12 months, 24 months, or other defined intervals.
- Engine Overhauls: Generally every 3,600 hours or 7 years, representing a major cost.
Comparative Table of Annual Operating Costs
| Annual Usage | Fixed Costs (USD) | Variable Costs (USD) | Estimated Total Cost (USD) |
|---|
| 150 hours | 387,500 | 292,384 | 679,884 |
| 300 hours | 387,500 | 584,768 | 972,268 |
| 500 hours | 387,500 | 974,612 | 1,362,112 |
These estimates are based on market averages and may vary depending on the aircraft’s condition, maintenance program, service provider rates, and fuel prices. (Source: aircraftcostcalculator.com)

Buy or Charter a King Air 300: Cost-Usage Arbitration
The decision to buy or charter a King Air 300 primarily depends on the planned annual usage and financial strategy.
The following estimates are based on the previously established operating and acquisition costs, for a hypothetical depreciation period of 10 years in case of direct purchase. Leasing costs generally include maintenance and insurance, simplifying operational management.
| Annual Usage | Purchase Option (average annual cost excluding depreciation, USD) | Charter/Leasing Option (estimated annual cost, USD) | Observations |
|---|
| 150 hours | 679,884 | 750,000 - 900,000 | Chartering can be more attractive for low to moderate usage. |
| 300 hours | 972,268 | 950,000 - 1,200,000 | Buying becomes competitive, offering better control. |
| 500 hours | 1,362,112 | 1,200,000 - 1,500,000 | Buying is generally more advantageous, optimizing the cost per flight hour. |
Charter figures are general estimates often including a portion of maintenance. The average annual purchase cost is calculated by spreading annual operating costs and a proportional part of the initial acquisition price over 10 years.
Analysis
For usage below 200 hours per year, chartering (via fractional ownership programs, operational leasing, or hourly charter) may prove more economically relevant. It offers flexibility, reduced fixed costs, and simplified administrative and technical management.
Beyond 250 to 300 annual hours, direct purchase offers the advantage of a lower hourly flight cost in the long term, total control over the aircraft, and potential residual value. However, it involves more complex management, high initial costs, and all the risks associated with ownership.

Owner Reviews
Positive Testimonial
« The King Air 300 is a workhorse. We use it for various missions, from executive transport to light cargo flights. Its reliability is exemplary, even on short or unprepared strips. Maintenance costs are predictable if the program is followed. It’s one of the best compromises between performance, payload capacity, and operating cost for our type of activities in the region. »
— Jean-Luc R., business owner – Nouvelle-Aquitaine, France
Nuanced Testimonial
« Our King Air 300 is a significant investment. While the cabin is spacious and passenger comfort is appreciated, one must be vigilant about maintenance costs. The Pratt & Whitney engines are robust, but major overhauls are expensive. Furthermore, original avionics systems may require costly upgrades to remain competitive and compliant with current regulations. It remains an excellent aircraft, but its operation demands rigorous budget management. »
