Beechcraft King Air 300 vs Beechcraft King Air 350

The Beechcraft King Air 300 and King Air 350 represent two generations of the same essential mission: a pressurized turboprop twin for owner-pilots and charter operators who want turbine reliability and high-altitude routing without the price of a jet. The King Air 300 (from 1983) uses Pratt & Whitney PT6A-60A engines for 320-knot cruise at FL310 — the highest-performance variant in the original King Air B200 series family. The King Air 350 (1990) stretched the fuselage again, added winglets, and used the same PT6A-60A engines but in a package that carries more passengers (up to eleven), further, with more comfort. The cross-shop is whether the 350's size premium is worth the price premium.

Which Should You Buy: Beechcraft King Air 300 or Beechcraft King Air 350?

Bottom line: Choose the King Air 300 for lower acquisition cost in the high-performance King Air family and a shorter fuselage that's operationally nimble at smaller airports. A King Air 300 at market price represents strong value for the speed, altitude, and reliability it delivers. Choose the King Air 350 when passenger capacity, range (approximately 1,806 nm vs. 1,571 nm for the 300), or the winglet efficiency benefits of the updated airframe define the mission. The 350's eleven-seat capacity serves charter operations and family operators that the 300's eight-seat configuration approaches less comfortably. Safety axis: both aircraft use the same PT6A-60A engines — identical turbine reliability and maintenance profile. The 350's winglets improve single-engine directional control margin at altitude, a genuine structural improvement that the 300 lacks. No other meaningful safety differential.

Pick the King Air 300 if…

  • Budget matters — from $947,809 vs $1,952,250, you save ~$1,004,441.
  • Lower operating cost — ~$1050/hr vs $1100/hr.

Pick the King Air 350 if…

  • More seats — 11 vs 9.
  • Longer range — 1806 nm vs 1700 nm.
  • Newer design — production from 1990 vs 1984.
  • More inventory — 50 listings vs 18.

Frequently Asked Questions

What is the difference between the King Air 350 and King Air 350ER?
The King Air 350ER (Extended Range) adds additional fuel tanks in the aft cabin area, extending range to approximately 2,400 nm — commonly deployed in medical evacuation, surveillance, and government/military roles where fuel range is critical. The standard 350's cabin is not modified. The 350ER is relatively uncommon in civilian Part 91 operations but well-established in special-mission applications.
Are the King Air 300 and 350 still in production?
The King Air 300 is no longer in production; it was superseded by the 350. The King Air 350 and its derivatives (350C cargo door version, 350ER extended range, 350i with updated interior) remain in current production at Textron Aviation's Wichita facility, making the King Air 350 one of the longest-running turboprop designs in history. New 350s come with Garmin G1000 NXi avionics.
What winglet benefit does the King Air 350 have over the 300?
The King Air 350's winglets (designed by Aviation Partners and incorporated in the original 350 design) reduce induced drag at cruise altitude, contributing to the 350's improved range and slight cruise efficiency advantage versus the 300. Winglets also improve single-engine handling margin by reducing asymmetric drag when one engine is inoperative — a real, if modest, benefit in single-engine emergency scenarios. The King Air 300 does not have winglets in its standard configuration.
Which is better, Beechcraft King Air 300 or Beechcraft King Air 350?
It depends on your mission and budget. The King Air 300 cruises at 295 kts with 1,700 nm range. The King Air 350 cruises at 295 kts with 1,806 nm range. Review the specs table above to find which fits your flying profile.
How do prices compare?
Beechcraft King Air 300: from $1,995,000. Prices vary by year, hours, avionics, and condition. Always get a pre-buy inspection.
What's the difference between Beechcraft King Air 300 and Beechcraft King Air 350?
Seats: 9 vs 11. Cruise: 295 vs 295 kts. Range: 1700 vs 1806 nm.
Which is cheaper to operate per hour?
King Air 300: about $1050/hr variable cost. King Air 350: about $1100/hr variable cost. Variable cost includes fuel, reserves and overhaul accruals. Annual fixed costs (hangar, insurance, annual inspection) add to the total.
Which has more seats and useful load?
King Air 300: 9 seats / 4,200 lb useful load. King Air 350: 11 seats / 5,400 lb useful load. Useful load = max gross weight minus empty weight; it determines how much fuel plus payload you can carry.
How does maintenance compare — TBO and overhaul cost?
King Air 300: 3,600-hour TBO, overhaul ~$400,000. King Air 350: 3,600-hour TBO, overhaul ~$450,000. Reaching the time-between-overhaul (TBO) triggers a mandatory engine/airframe rebuild that affects resale value.
