The King Air 350 is the stretched, winglet-equipped flagship of the line: a double-club cabin for eight with commuter seating to eleven, 312 kt cruise and 1,806 NM of range. The 350i brought a quieter, fully refreshed interior; the airframe's utility DNA is unchanged.
At 15,000 lb maximum takeoff weight it delivers genuine payload-with-full-fuel flexibility that the smaller King Airs trade away, while keeping the family's short, hot and unpaved runway manners.
The aircraft
The 350 is the King Air line taken to its logical limit. Beechcraft started with the Model 300 — a hotter-engined development of the 200 — stretched the fuselage by nearly three feet, added two more cabin windows per side and fitted winglets, creating the aircraft delivered from 1990 as the Super King Air 350 (formally the Model B300). Certification in the commuter category allowed the 15,000 lb maximum takeoff weight, which is what gives the type its payload-with-full-fuel flexibility and its double-club-plus cabin.
The formula proved so right that the airframe has barely changed in thirty-five years. The 350ER added extended-range tankage and higher weights for special-mission work; the 350i of 2009 rebuilt the cabin around noise reduction and connectivity; Pro Line Fusion flight decks arrived on new aircraft from 2015; and the King Air 360, announced in August 2020, added the ThrustSense autothrottle, a lower cabin altitude and a redesigned interior. Underneath, the wing, the PT6A-60A engines and the field performance are the same story told better.
Production continues at Wichita, and the surveillance, air-ambulance and flight-inspection fleets built on the 350 keep growing. For a used buyer that continuity matters: parts, training and engineering knowledge for a 1990s airframe are the same ones supporting aircraft delivered last month — a claim almost nothing else in this class can make.
Key figures
Standard published figures for a typically equipped Beechcraft King Air 350i. Individual airframes vary with configuration and modification — the specification on a listing is what governs.
We do not hold a Beechcraft King Air 350i on the books this week, but we place the type regularly. Tell us the specification, hours and budget, and we will come back with airframes that are genuinely available.

The broker’s view
The 350 holds value exceptionally because it has no true rival: nothing else pairs this cabin and field performance in a twin. Corporate examples with the Pro Line Fusion deck (from 2015) form the premium tier; earlier Pro Line 21 aircraft are the value play.
Special-mission demand — survey, air ambulance, ISR — keeps a permanent bid under good airframes.
The family
The 1990 original: stretched cabin, winglets and 15,000 lb MTOW over the 300's engines. Most wear Pro Line II or, later, Pro Line 21 avionics — the panel fit is the main price separator among early airframes.
Higher weights and extended-range fuel for special-mission and long-sector work. Many led hard surveillance lives, so provenance and usage history deserve extra scrutiny; a clean civilian ER is a genuinely long-legged machine.
From 2009: a substantially quieter cabin with new interior, lighting and connectivity. Performance is unchanged, but the passenger experience is a class above — 350i airframes carry a consistent premium over equivalent-time 350s.
The current flagship, delivered from late 2020: Pro Line Fusion, ThrustSense autothrottle, lower cabin altitude and a redesigned interior. Nearly-new examples trade rarely and briefly.
Common questions
Published maximum range is around 1,806 NM — six hours, or Johannesburg to Nairobi with reserves.
Short, hot, high and unpaved runway capability, lower fuel burn per trip and a larger cabin than most light jets — for multi-stop regional missions the 350 frequently beats a jet on both time and cost.
The 350i, from 2009, introduced a substantially quieter cabin with new interior, lighting and connectivity. Performance is unchanged; cabin experience is not.
Meaningfully less per hour than the light and midsize jets it competes with, on fuel above all. The PT6A-60A overhaul cycle is the dominant scheduled cost, and the type's enormous global fleet keeps parts and labour competitively priced on every continent.
It is one of the type's defining strengths: full-cabin departures from high-elevation African strips in summer temperatures are routine, with honest single-engine climb figures where many light jets are payload-limited or excluded entirely. Johannesburg-based operators buy the 350 for exactly this reason.
Yes — Pro Line 21 aircraft can be brought to Pro Line Fusion through established retrofit programmes, and older panels have upgrade paths as well. A Fusion-equipped 350 trades closer to the 350i tier, so the investment is usually recovered at resale.
