Beechcraft King Air 90/200 Series

The King Air is the best-selling turboprop family in aviation history, with Beechcraft delivering nearly 7,600 aircraft across all variants between its 1964 launch and 2020, and approximately 6,320 aircraft still active worldwide having collectively logged more than 63 million flight hours. The Model 90 series alone (including the 100 siblings) accounted for more than 3,100 deliveries, and the 200/B200 series added over 1,800 more across four decades of production. The airplane's enduring appeal rests on a simple formula: two reliable Pratt & Whitney Canada PT6A turboprops, a pressurized cabin that can carry six to nine people in genuine comfort, a wide CG envelope, docile handling, and a global support network that makes it feasible to operate from almost any region on earth.

The King Air 90 series (C90, E90, F90, C90A, C90B, C90GT, C90GTi, C90GTx) is the "light" cabin-class turboprop: a conventional tail, modest PT6A-21 or PT6A-135A engines, 10,100-10,485 lb MTOW, and roughly 246 KTAS cruise. It is the entry point to King Air ownership, typically operated by owner-pilots, small charter operators, medevac outfits, and corner-office flight departments. The 90-series production line closed in March 2021 when Textron discontinued the C90GTx.

The King Air 200 series (200, B200, B200GT, B200GTi) is the "Super King Air" that every pilot associates with the name: T-tail, 850 shp PT6A-42 (later -52) engines, 12,500 lb MTOW, a 35,000 ft service ceiling, and true 280-290 KTAS cruise with a 1,500-1,800 nm range. It is the workhorse of air ambulance, government surveillance, Part 135 charter, fractional, and mid-size corporate fleets, and the current Textron catalog successor (King Air 260) is a direct descendant. Compared to single-engine turboprops like the pilatus-pc12 and daher-tbm, the King Air trades efficiency and acquisition cost for two-engine redundancy, a bigger cabin, and better unimproved-runway tolerance. Compared to its larger sibling the beechcraft-king-air-350, the 200 sacrifices roughly 10 KTAS, 400 lb useful load, and cabin length, but costs meaningfully less to acquire and operate.

A typical C90B owner plans on 220-230 KTAS true at FL200-240 burning roughly 70 GPH total (35 GPH per side), not the 246 KTAS book max cruise. The airplane is flat-rated and unpressurized-below-aggressive-altitudes; real-world trip planning for a 500-700 nm leg is typically done in the low flight levels where the PT6A-21 still has power to give. The C90GT/GTi/GTx lifts cruise to a genuine 265-272 KTAS because the flat-rated PT6A-135A holds rated power higher into the climb, and climb rate improves noticeably (roughly 2,100 fpm vs 1,950 fpm for a C90B).

The B200 is where the family becomes a true high-flight-level platform. With PT6A-42s it will climb to FL280 in about 18 minutes at max gross and cruise at a legitimate 280-289 KTAS on roughly 700-750 lb/hr (105-112 GPH) total. The B200GT/GTi with PT6A-52 engines gains about 12-14 KTAS at FL280 and shortens time-to-climb to the mid-flight-levels, which is where most of the real-world operating efficiency advantage comes from. All 200-series aircraft are 35,000 ft certified, but most operators cruise FL250-290 where the PT6A is happiest.

Hot-and-high performance is a King Air hallmark. The 200-series has single-engine climb performance that outperforms many light jets; the 90-series is more modest but still adequate. Book single-engine service ceiling for the B200 is approximately 21,000 ft at max gross.

C90B:

• Max fuel (384 gal / 2,573 lb): useful load of ~2,140 lb leaves roughly 2 pilots + 3 passengers with bags for a 900-1,000 nm leg.
• Full seats (6 pax + pilot, ~1,200 lb): can carry approximately 900 lb of fuel (134 gal) for a 350-450 nm leg.
• Practical sweet spot: 4 pax + bags + 280 gal fuel for a comfortable 700 nm trip with reserves.

B200:

• Max fuel (544 gal / 3,645 lb): useful load of roughly 4,200 lb leaves 570 lb for pilots and passengers — NOT full cabin at max fuel.
• Max payload (roughly 2,500-2,700 lb after typical two-crew and BOW): approximately 1,500 lb of fuel (224 gal) for a 550-700 nm leg.
• Realistic 6 pax + bags (1,400 lb): 2,800 lb fuel / 418 gal enables approximately 1,200-1,400 nm with reserves.
• Full-fuel / 4-pax mission: 1,700-1,800 nm no-wind range at long-range cruise.

This is the classic King Air tradeoff — the airplane does not make the pilatus-pc12's "full seats and full tanks" claim, but it carries substantially more structure, redundancy, and cabin volume than any single-engine turboprop in the class.

Business Travel (10 for B200, 8 for C90-series): This is the airplane's core mission. A B200 carries six passengers in a pressurized, club-seated, stand-up (well, stoop) cabin at 280 KTAS over 1,500 nm with full IFR dispatch reliability, and it can do it into airports that would not accept a light jet. The C90 series is slower and shorter-range but still genuinely capable for 500-800 nm legs with four pax.

Cross-Country (9): A B200 makes continental U.S. trips in a single leg with reserves; a C90 stretches to two legs. Both handle weather, ice, and high altitudes that ground piston twins.

Cargo Hauling (8): Useful load on the B200 is 4,000+ lb, the airplane tolerates unimproved runways, the clamshell cargo door on many variants accepts bulky freight, and PT6A reliability makes it the gold standard for feeder-freight operators. The C90 is more limited at ~2,100 lb useful load.

Surveying (8): Long endurance (5+ hours), high ceiling, stable platform, and easy pod/antenna installation make both variants popular for aerial survey, photo-mapping, ISR, and atmospheric research.

Flight Training (2): Absolutely not a primary or instrument trainer. It is a Part 142 recurrent training platform for owner-pilots already typed. Insurance floor alone excludes it from primary instruction.

Backcountry (3): The 90-series will operate from 3,000-3,500 ft unimproved strips and has done so for decades in Africa, South America, and Alaska; the B200 is more demanding. Neither is a cessna-208-caravan or pilatus-pc6-porter, but both outperform any light jet on unimproved surfaces.

Aerobatics (1): Transport-category twin. No.

Local Fun Flying (2): Operating cost of $1,000+ per hour makes "hundred-dollar-hamburger" flying absurd. People who own King Airs for fun are wealthy enough that it does not matter.

The King Air spans the full spectrum of cockpit evolution from 1960s steam gauges to modern integrated glass.

• Legacy steam / early EFIS (pre-1990 C90s, 200s): Collins or Bendix/King radios, mechanical HSI, flight director. These aircraft are heavily devalued unless owners have invested in avionics modernization. A common path is a Garmin G600 TXi or dual G600 plus GTN 750 stack, which runs $150-250K installed and adds materially to resale.
• Mid-era (C90B, B200 1990s-early 2000s): Typically Collins Pro Line II or Universal UNS-1 FMS with CRT EFIS. Aging display hardware is the main upgrade driver.
• Collins Pro Line 21 (C90GTi, B200GTi): Factory glass with FMS, integrated radios, dual PFD/MFD. Highly desirable on the used market and largely self-sufficient for Part 135.
• Garmin G1000 NXi retrofit: Available for older 90 and 200 airframes through Textron and STC shops like Blackhawk and Textron's own service centers. Install runs $300-450K but dramatically modernizes the panel, adds synthetic vision, ADS-B, and integrates with autothrottle STCs.
• Autothrottle: The IS&S ThrustSense autothrottle STC (~$175K installed) is increasingly common on owner-flown B200s and is standard on the factory King Air 260. Reduces pilot workload and mitigates torque-event risk.

See avionics-pricing for current installed costs.

• Blackhawk XP21/XP52 engine upgrades: Replace PT6A-21 (C90) with PT6A-135A (XP21, ~$800K+ installed) or PT6A-42 with PT6A-52 (B200 XP52, ~$1.2M installed). Adds substantial cruise speed and climb performance; whether it pencils out depends on remaining airframe life.
• Raisbeck Performance Systems: Quiet 4-blade or 5-blade props, ram-air recovery system, wing lockers, dual aft-body strakes, high-flotation gear doors, and the EPIC platinum performance package. The most popular single mod on the fleet; a well-equipped Raisbeck B200 can carry 200+ lb more useful load and gain 10+ KTAS.
• BLR Aerospace winglets: Reduce fuel burn roughly 3-5%, improve climb, and reduce runway requirements. ~$100K installed.
• Hartzell swept-tip composite propellers: Available for 90 and 200 series, lower noise, better performance, longer TBO.
• G1000 NXi / Pro Line Fusion retrofit: Modernizes 1980s-90s airframes.
• Thrust reverser upgrades, BLR dual aft-body strakes: Common on cargo/medevac fleets.

King Air maintenance is a professional-grade endeavor, but the global support network makes it among the easiest turbine aircraft to own outside of perhaps the Caravan.

Annual inspection: $20,000-$45,000 for a routine year on an honest airframe; $75,000-$150,000 in a SID/corrosion-discovery year. Scheduled at every 12 calendar months or per a phase inspection program.

Hot Section Inspection (HSI): PT6A hot sections are accomplished at mid-TBO (every 1,800 hours on -42/-52). Shop cost approximately $40,000-$50,000 per side, sometimes more depending on blade and vane condition. Budget $80,000-$100,000 per HSI event on a B200.

Overhaul: PT6A TBO is commonly 3,600 hours (TBO varies slightly by model and dash number). Full overhaul cost runs $255,000-$425,000 per engine depending on facility, inducted condition, and scope. A premium P&WC flat-rate program with guaranteed CT blade replacement runs up to $577,000 per side. Budget $700K-$900K for a both-engine event on a B200, $500K-$700K on a C90.

Engine programs: Pratt & Whitney ESP Platinum, JSSI, and similar per-hour programs are nearly universal on professionally operated airframes. Rates run roughly $275-375/hour per engine depending on coverage level. Enrollment substantially protects resale value.

Parts availability: Excellent. Textron continues to actively support the fleet; Blackhawk, Raisbeck, Stevens Aerospace, Epps Aviation, Elliot Aviation, and dozens of other authorized service centers hold inventory and PMA alternatives are widely available for airframe components.

Mechanic familiarity: Common but specialized. Every turboprop shop in the country knows King Airs; general-aviation field mechanics typically do not.

Hourly direct operating cost:

• C90B: $800-$1,100/hour fuel + maintenance (not including reserves, insurance, hangar, training)
• B200: $1,300-$1,800/hour direct; all-in budget of $400,000-$500,000/year at 300 hours, and up to $1.1M-$1.4M/year at 450 hours per the Conklin & de Decker and Aircraft Cost Calculator references.

See maintenance-ecosystem for parts, overhaul shops, and annual cost methodology.

Market pricing spans an enormous range across this family and is dominated by year, engine time remaining to HSI and TBO, avionics, and STC package.

King Air C90 series:

• Older C90/E90 (1971-1982): $400K-$700K for typical airframes
• C90A (1984-1992): $600K-$950K
• C90B (1992-2005): $800K-$1.6M, with late-model Raisbeck-equipped aircraft at the top
• C90GT/GTi (2006-2009): $1.3M-$2.1M
• C90GTx (2010-2021): $1.8M-$3.0M
• Aircraft Bluebook Summer 2024: C90 range cited as $1.17M (1985) to $2.05M (2005)

King Air 200 / B200 series:

• Original 200/early B200 (1974-1985): $700K-$1.3M
• B200 (1986-2007): $1.3M-$2.8M; 45 currently listed on GlobalAir ranging $1.29M-$3.99M
• B200GT (2008-2010): $2.8M-$3.6M, averaging about $3.31M per AvBuyer
• B200GTi / King Air 250 (2011-2020): $3.5M-$5.0M

Engine value ("green time"): PT6A time remaining to HSI and TBO is the single biggest valuation variable after model year. Fresh overhaul adds $250-400K per side to book value; engines approaching TBO can discount an airplane by $500K-$800K. "On condition" / engine program enrollment (P&WC ESP, JSSI) substantially supports value because buyers avoid the overhaul gamble.

Avionics premium: A Pro Line 21 or G1000 NXi retrofit on an otherwise steam-gauge airframe adds $150-300K of perceived value.

Raisbeck/Blackhawk/BLR mods: Typically recover 50-70% of install cost in resale.

See valuation-methodology for detailed engine/avionics/STC value formulas.

• Wing fitting AD (2020, FAA 2020-26-16): Applies to certain 90, 100, 200, and 300 series aircraft; requires inspection of the lower forward wing fittings for fatigue cracks after reports on two airframes, following a 2015 in-flight wing separation accident. Recurring inspections required until terminating action.
• Empennage/spar corrosion (SAIB CE-19-15): Applies to F90, 200, B200, 300, B300. Beechcraft reported approximately 100 repairs in a decade for structural corrosion of the horizontal and vertical stabilizer rear spar caps. Not an AD but a strong inspection recommendation.
• Beechcraft Service Instructions / SIDs: Textron publishes Structural Inspection & Corrosion Program documents that aging fleet operators must address at annual to keep the airframe healthy. Cost exposure on a 40-year-old 90-series can be significant.
• Flap actuator, landing gear actuator, and pressurization controller: Common wear items on 30+ year airframes.
• PT6A common issues: Compressor turbine (CT) blade erosion, fuel nozzle fouling, first-stage compressor blade cracking. All addressed via scheduled borescope and hot-section inspection.
• Pre-buy red flags: Corrosion in the wing center section, damp insulation behind the cabin sidewalls, engine logs with gaps around HSI/overhaul events, mismatched engine times on a twin, and salt-environment operation history.

King Airs sit firmly in the turboprop-twin insurance category, which means annual premiums bear little resemblance to piston-twin economics. Typical current-market numbers:

• Hull insurance: 0.25-0.50% of agreed value annually. A $2.15M B200 runs roughly $5,000-$10,000/year hull; a $700K C90 might run $3,500-$5,500/year hull.
• Liability: $10,000-$25,000/year at $1M smooth or $5M combined single limit. Underwriters will push up to $20,000 for a B200 carrying passengers for hire.
• Total annual premium: $15,000-$35,000 for owner-flown operations; $25,000-$60,000+ for Part 135.

Underwriting requirements:

• Type-specific initial training at FlightSafety, SimCom, or CAE (no exceptions; underwriters will not quote without it).
• Annual recurrent training in type at an approved simulator center — treated as non-negotiable.
• Minimum experience: Typically 1,500 hours total, 500 multi-engine, 100 turbine for C90; 2,000/750/250 for B200 absent type time. First-year owner-pilots often fly with a mentor pilot for 25-50 hours.
• Two-pilot crews required for Part 135 operations and for most corporate flight departments.
• Maximum pilot age considerations become relevant past 70; some underwriters require additional medicals or exclude single-pilot operations.
