Eight decades of continuous production made the Bonanza and Baron the best-understood collateral in general aviation. Production is ending — the pre-owned market is not. Financing the piston Beechcraft line is what this page covers. For the King Air and Denali, see the turbine Beechcraft page.
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 6.22%. A well-documented example with a current engine and up-to-date avionics underwrites the same way it always has.
Where did the King Air go? The turbine side of the Beechcraft brand — the King Air 260 and 360 twin turboprops and the new Denali single — now has its own dedicated page. The rate category, the lender pool, the engine-program conversation, and the age-formula math are all different once you cross the turbine line, and the turbine conversation deserved its own room. If your Beechcraft has a PT6 on the front — or a GE Catalyst — start at King Air & Denali financing.
This page covers the piston line: the Bonanza in all its generations, the Baron light twin, and the underwriting realities of financing aircraft whose newest examples are the last of the line and whose oldest are approaching eighty years old.
Late-model G-series, mid-generation classics, and vintage airframes each underwrite differently. All finance at the certified piston rate.
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, Garmin G1000 NXi in later examples. Textron announced the end of new production in November 2025 once the remaining backlog is filled. Recent-year pre-owned examples are the last of the line, and lender familiarity is as deep as it gets — the Bonanza has been financed continuously for eight decades.
The Baron G58 is Beechcraft's light twin — dual Continental IO-550-C engines, six seats, and a Garmin G1000 NXi panel in later examples. Production ends alongside the Bonanza. Twin-engine piston underwriting adds a documentation layer relative to a single: two engines' worth of logbook scrutiny, multi-engine insurance requirements, and a lender pool that has cooled somewhat on piston twins in recent years. A clean, well-documented G58 still finances on standard certified piston terms — the file just needs to be tighter.
The classic Bonanza fleet — straight-tail A36s and F33s, and the iconic V-tail V35 series — is one of the deepest pre-owned markets in GA. Lenders know these airframes intimately; what drives the individual deal is age, engine status, damage history, and panel. Pre-1980 airframes trip the age-plus-amortization formulas some lenders apply, which shortens available terms with certain lenders but not others. A mid-time IO-520/550 with clean logs and a modernized panel is very placeable at full terms.
The turbine side of the Beechcraft house — the King Air twin turboprop family in continuous production since the 1960s, and the new Denali single-engine turboprop — finances in a different rate category with a different lender pool, engine-program requirements, and age-formula math. The full treatment lives on its own page: model cards for the 260, 360, pre-owned 200/250/350 series, and the Denali, payment tables, and the turbine underwriting conversation.

Late-model singles, twins, and vintage airframes each have their own dynamics.
Every piston Beechcraft — G36, G58, classic Bonanzas, older Barons — finances at the certified piston rate of 6.22%. The deepest lender pool in general aviation, which means competition works in your favor on a clean file.
A Baron underwrites like a certified single with double the engine documentation. Lender appetite for piston twins has cooled industry-wide — maintenance exposure on two engines and the performance of modern singles both play a role — so the Baron file needs current engines, complete logs, and a realistic operating budget. Clean examples still close on standard terms.
Some lenders cap airframe age plus amortization. A 1978 V35B may see a 15-year term with one lender and 20 with another. Vintage Bonanzas are absolutely financeable — routing the file to the lender whose formula fits your airframe is part of what FLYING Finance does.
The IO-550's TBO and the aircraft's position against it drive value on every piston Beechcraft. An engine at or near TBO isn't a dealbreaker — an overhaul can often be rolled into the loan — but it must be priced into the deal, not discovered at the pre-buy.
Retractable gear raises the training bar on every Bonanza; the Baron adds multi-engine requirements. Time in type is the biggest premium lever — get dual in type before binding. See the insurance guide for the full picture.
15% minimum on standard transactions with strong credit; 20% typical on vintage airframes, twins with marginal documentation, or credit-builder files. Larger down payments can offset age-formula constraints on older aircraft.
