These figures are typical for the model, not a specification for any individual aircraft. Real-world numbers vary with year, installed equipment, weight, modifications and engine condition — often by more than you would expect. Use them to compare types, and confirm anything you would act on against the Pilot's Operating Handbook for that specific airframe and a prebuy inspection.

Annual all-in

All-in at ~100 flying hours a year, using the midpoint of each range — the same figures broken out under “Cost to own” below. Your number will differ, and mostly for two reasons. Experience sets your insurance: a 2,000-hour pilot with recent training pays 30–40% less than a 200-hour owner, and student owners pay 20–40% more — on the same aircraft that is often a doubling. Location sets your hangar: a T-hangar runs $200–400 a month in the Midwest against $400–1,500 in a coastal metro, and an outside tie-down is less again. Engine reserves move too — a local shop reusing your serviceable cylinders can come in 30–50% under the national specialty-shop pricing we quote, though you trade the warranty and turnaround that comes with it. Reserves are money set aside toward a future overhaul, not a bill this year, and the annual inspection figure is the shop’s labor to look — whatever they find is separate.
Cost to own — estimate
Set your yearly hours and local fuel price. Fixed costs (insurance, hangar, annual inspection) don't change with hours; fuel, maintenance and the engine reserve do.

Fuel, engine reserve and wear only. Insurance, hangar and the annual are already paid whether you make the trip or not, so they are not charged here.
Estimate, not a quote. Where a line shows a range, the total, per-hour and per-mile figures use its midpoint— insurance moves most with your experience and time in type, hangar with where you base the aircraft, so your own number could sit at either end. Annual inspection is the shop's labor to open and inspect — what they find is the maintenance line, which covers oil changes, plugs, tires, brakes, hoses, lights, a battery and vacuum pump amortised over their life, and the unscheduled squawks that are the largest and least predictable part of it. Reserves are sinking funds toward an overhaul, not a bill you pay this year — and note that a propeller is due on hours or calendar time, typically six years, so flying less does not put it off forever.
Strengths
- Dual cargo doors for flexible loading and passenger comfort
- Most popular Baron variant; strong parts/service support ecosystem
- 200+ KTAS cruise with 6-seat cabin and 1,480 NM range
- IO-550-C models (1984+) offer proven reliability and 15 HP increase over IO-520
Weaknesses
- Cargo door seals deteriorate; water intrusion and cabin drafts common
- Engine matching critical; mismatched TBO positions costly to address
- Single-engine ceiling only 7,400 ft; requires careful mountain operations
- 58TC/58P variants trade reliability for modest speed gain; market discounts them
Overview
The 1970 Beechcraft Baron 58 was the stretched, cargo-door successor to the Baron 55 -- 10 inches longer fuselage, dual cargo doors on the right side (similar to the A36 Bonanza), and 285 HP per side as standard. The 58 quickly became the most popular Baron variant and remained in production through 2005 in this pre-G58 configuration, with a G1000-equipped G58 succeeding it for current production.
Approximately 2,500 Baron 58s (and 58TC/58P pressurized variants) were produced through 2005. The Baron 58 has been described as the gold standard for owner-flown light twins -- comfortable 6-seat cabin, dual cargo doors for cargo flexibility, twin-engine redundancy, and 200+ KTAS cruise performance.
The Cargo Door Advantage
The 58's signature feature is dual right-side cargo doors (one for cargo, one for passengers in the rear). These doors enable:
- Stretcher loading for medical missions
- Bulk cargo without disassembly
- Easier passenger boarding/deplaning in three rows
- Photo/survey installations
This cargo door arrangement, shared with the A36/G36 single-engine sibling, sets the Baron 58 apart from the 55 series (single left door only) and most competitor twins (Cessna 310, Piper Aztec).
Variants & History
| Variant | Years | Engine | HP each | Notes |
|---|---|---|---|---|
| 58 | 1970-1983 | Continental IO-520-C | 285 | Standard 58, most produced |
| 58 (post-1984) | 1984-2005 | Continental IO-550-C | 300 | Higher HP, refined |
| 58TC | 1976-1984 | Continental TSIO-520-WB | 325 each | Turbocharged variant |
| 58P | 1976-1984 | Continental TSIO-520-WB | 325 each | Pressurized cabin |
The NA 58 (1984-2005 with IO-550) is the most desirable common variant -- improved cylinder reliability over IO-520 and 15 HP more power per side.

Performance
Representative 58 (1984+ IO-550-C 300 HP per side):
- Cruise: 200 KTAS at 7,500 ft (75% power)
- Climb: 1,700 FPM at gross
- Single-engine ceiling: 7,400 ft
- Fuel burn: 27 GPH cruise (13.5 GPH per side)
- Range: 1,480 NM with 194 gal fuel
- Useful load: 1,850 lbs
58TC/58P performance at FL200: 220 KTAS cruise, 1,450 NM range -- significantly faster than NA 58 but with much higher maintenance complexity due to turbo + pressurization.

Valuation Factors
| Variant | Condition | Price Range |
|---|---|---|
| 58 (IO-520, pre-1984) | Flying but tired | $160,000-$235,000 |
| 58 (IO-520, pre-1984) | Well-maintained | $230,000-$330,000 |
| 58 (IO-550, 1984-1995) | Well-maintained | $260,000-$420,000 |
| 58 (IO-550, 1996-2005) | Well-maintained | $360,000-$580,000 |
| 58TC | Well-maintained | $200,000-$330,000 |
| 58P | Well-maintained | $240,000-$390,000 |
58TC/58P discount to NA 58 reflects market consensus that turbo + pressurization complexity outweighs the speed/altitude benefit for most owner-flown operations -- a meaningful contrast to single-engine markets where turbo variants often command premium.
ADs & Common Problems
Universal Baron pre-buy concerns apply. 58-specific:
- Cargo door seals: Right-side double doors have complex sealing; deterioration causes water intrusion and rear-cabin cold drafts.
- Engine matching: As with Baron 55, both engines should be similar TBO position.
- Continental IO-520 vs IO-550: Pre-1984 IO-520 known for top-end cylinder issues at mid-time. IO-550 (1984+) is meaningfully more reliable.
- 58TC turbocharger condition: 58TCs require especially careful turbo inspection; turbo replacement: $5,000-$10,000 per side.
- 58P pressurization vessel condition: Cabin pressure vessel must be tested. Pressurization leak repairs are specialized and expensive.
- AD 2002-26-04 (forward bulkhead): Applies to Baron 58; verify compliance.
- Spar carry-through corrosion: As with 55-series, inspect carefully.
