The Beechcraft brand spans pre-owned Bonanzas and Barons, the King Air twin turboprop family, and the new Denali single-engine turboprop. Each underwrites differently. FLYING Finance knows all three conversations.
Textron announced the end of Beechcraft Bonanza and Baron production in November 2025. Once the remaining order backlog is fulfilled, no new Bonanzas or Barons will be built. The pre-owned market for both aircraft remains active - tens of thousands are flying, factory parts support continues, and neither type is going away. The Bonanza G36 and Baron G58 finance at the certified piston rate of 6.46%. A well-documented example with a current engine and up-to-date avionics underwrites the same way it always has.
Textron's bet on the Beechcraft brand's future is the King Air family and the Denali. The King Air 260 and 360 are twin-engine turboprops that have been in continuous production since the 1960s and finance at the turboprop rate of 6.37%. The Denali - a clean-sheet single-engine turboprop powered by the GE Catalyst engine - received FAA type certification in February 2025 with first deliveries expected in 2026 at an estimated $6.5-7M.
The rate changes when you cross the turbine line. A Bonanza G36 is a certified piston at 6.46%. A King Air 260 is a turboprop at 6.37%. A Denali is a turboprop at 6.37%. Knowing which side of that line your aircraft sits on before you apply determines which lender pool you go to and what documentation you need to have ready.
Three financing conversations across the Beechcraft brand. Pre-owned certified piston, twin turboprop, and the new single-engine turboprop.
The Bonanza G36 is the final variant of the aircraft that first flew in December 1945 - the longest continuous production run in aviation history. Continental IO-550-B engine, six seats, retractable gear, and a V-tail or conventional tail depending on the year. Textron announced the end of new production in November 2025 once the remaining backlog is filled. Pre-owned examples from recent years are the last of the line. Lender familiarity with the Bonanza is high - it has been financed continuously for eight decades. Finances at 6.46% as a certified piston aircraft.
The Baron G58 is Beechcraft's light twin-engine piston - dual Continental IO-550-C engines, six seats, pressurized fuel system, and a Garmin G1000 NXi panel in later examples. Textron announced the end of new production alongside the Bonanza in November 2025. Multi-engine piston underwriting adds documentation complexity relative to a single - insurance covers both pilots and multi-engine operational requirements apply. Pre-owned Baron G58s in the $700K-$1.2M range represent some of the most capable non-pressurized twins available. Finances at 6.46%.
The King Air family has been in continuous production since the 1960s. The King Air 260 is the current light-twin variant - dual Pratt and Whitney Canada PT6A-52 engines, nine seats, 316-knot cruise, and a Garmin G1000 NXi panel. The King Air 360 is the larger variant with PT6A-60A engines, 11 seats, 312-knot cruise, and a Garmin G3000 panel. Both finance at the turboprop rate of 6.37%. Engine program enrollment - JSSI or ESP Gold - is standard for King Air transactions and affects underwriting favorably. Lender familiarity with King Air collateral is among the highest of any turboprop type.
The Beechcraft Denali is a clean-sheet single-engine turboprop powered by the GE Catalyst engine - the first new clean-sheet turboprop engine in decades. The GE Catalyst received FAA engine certification in February 2025. Textron expects aircraft type certification in 2026, with service entry to follow. The certification program has amassed more than 3,330 flight hours across three test aircraft as of late 2025. The program has experienced repeated timeline delays since its 2015 announcement. Buyers should confirm current delivery timeline directly with Textron Aviation. Finances at 6.37%. The Denali is designed to compete with the Pilatus PC-12 in the pressurized single-engine turboprop segment: high useful load, modern Garmin avionics, and turboprop efficiency at a price point below the King Air 360. As a new type, lender familiarity is still building. FLYING Finance will route Denali transactions to lenders with turboprop experience who can underwrite new-type collateral correctly. Finances at 6.37%.

Pre-owned piston, King Air turboprop, and Denali new type each have different underwriting dynamics.
The Bonanza G36 and Baron G58 are certified piston aircraft at 6.46%. The King Air 260, King Air 360, and Denali are turboprops at 6.37%. The rate difference is modest but the lender pools are distinct. Confirm your aircraft category before applying so we route to the correct lenders from the start.
Engine program enrollment is standard on King Air transactions. JSSI and ESP Gold (Pratt and Whitney) are the primary programs for the PT6A series. An unenrolled King Air represents an open-ended maintenance liability that affects both lender appetite and your budget. Enrollment at purchase is advisable - and a GLADA-affiliated broker will often recommend it before you close.
Most turboprop lenders apply an age-plus-amortization formula: the aircraft's age plus the loan term cannot exceed 23, 25, or 30 years depending on the lender. A 2005 King Air 350 is 21 years old in 2026. At a 23-year cap, a lender applying that formula allows a two-year loan. At 30 years, a 20-year amortization is available. Vintage King Airs are financeable - knowing which lender's formula fits your aircraft is part of what FLYING Finance does.
Lender familiarity with Bonanza and Baron collateral is high - both types have been financed continuously for decades. A well-documented pre-owned example with a current engine and a clean maintenance history underwrites straightforwardly. Vintage Bonanzas (pre-G35) require more lender selectivity - the same age-formula considerations that apply to King Airs apply here for older piston airframes.
As a new type with certification expected in 2026 and deliveries to follow, the Denali's lender familiarity is still developing. Lenders experienced with the PC-12 and TBM lines are the natural starting point - similar mission, similar price range, similar collateral profile. FLYING Finance will route Denali transactions to turboprop-experienced lenders who can value the type correctly as delivery data becomes available.
15% minimum across the Beechcraft lineup for standard transactions. King Air commercial use transactions and Denali purchases may see lenders request 20% given the higher loan values and - for the Denali - the limited transaction history on the new type. Business use documentation strengthens the file at any price point above $1M.
