Beechcraft Bonanza V35B V-tail (Late)

The later V-tail Bonanzas (J35 through V35B, 1958-1982) represent the mature, high-performance era of Beechcraft's iconic design. With the introduction of fuel-injected Continental IO-470 and IO-520 engines, these models deliver true 170+ KTAS cruise speeds, making them some of the fastest naturally aspirated piston singles ever produced.

The V35B (1968-1982) is the definitive V-tail — powered by the IO-520-BA producing 285HP, with 80-gallon fuel capacity and a 3,400 lb gross weight. It represents the final evolution of the V-tail design before Beechcraft dropped the configuration in favor of the conventional-tail Bonanza 33 and 36 lines.

Approximately 6,600 later V-tail Bonanzas were built, and over 6,000 V-tail models of all years remain flying today. The V35B alone accounts for over 1,500 units produced.

The later V-tails are serious cross-country machines — fast, comfortable, and with the range to make 600+ nm legs. They remain popular with experienced pilots who appreciate the distinctive handling and aesthetics of the V-tail, despite the insurance and maintenance premium associated with the ruddervator ADs.

The V35B delivers a book cruise of 172 KTAS at 75% power — a genuine 200 mph airplane. Real-world owners consistently report 165-175 KTAS depending on altitude, weight, and leaning technique. At economy cruise (55-60% power), expect 155-160 KTAS on 11-12 GPH, which extends range considerably.

The S35 was the breakout model — the jump from IO-470 (260HP) to IO-520 (285HP) made a noticeable difference in climb and cruise. All S35-and-later models are considered the most desirable V-tails.

The V-tail configuration provides a slight speed advantage (2-4 knots) over the straight-tail F33A with the same engine and weight, due to reduced interference drag. The tradeoff is the coupled pitch-yaw response of the ruddervators, which requires deliberate coordination technique, especially in turbulence.

The V35B-TC turbocharged variant (only 89 built) maintains sea-level power to higher altitudes but adds turbo system complexity and maintenance cost. It's uncommon and not widely sought after.

V35B (IO-520-BA, 285HP, 80 gal fuel):

The V35B's 3,400 lb gross weight and 1,294 lbs useful load make it one of the more payload-friendly 4-seat retractable singles. With 80 gallons standard, you can fly 700+ nm legs with two adults and bags without touching reserves. Four adults with full fuel works but limits baggage. The 80-gallon standard fuel system is one of the V35B's strongest selling points — many competing aircraft require optional tanks to approach this range.

• Flight Training (2): Insurance prohibitive for training. High performance and retractable gear inappropriate for primary. Only for advanced ratings and complex/HP endorsements with an experienced instructor.
• Backcountry (2): Low-wing retractable with 64 KIAS clean stall and 590 ft landing roll. Not designed for unimproved strips. Prop strike risk on rough surfaces.
• Business Travel (7): Excellent point-to-point speed with IFR capability. 170+ KTAS gets you there fast. Four comfortable seats with baggage. The quintessential owner-flown business airplane of the 1970s-80s.
• Aerobatics (1): Absolutely not. The V-tail's documented history of in-flight structural failure under extreme loads makes any aerobatic maneuvering dangerous and irresponsible. Utility category only.
• Cross-Country (9): This is what the Bonanza does best. 731 nm range at cruise, 170+ KTAS, comfortable cabin, IFR capable. One of the best cross-country singles ever built.
• Cargo Hauling (3): Four-seat cabin, limited cargo door. Useful load of 1,294 lbs is generous but the cabin volume constrains bulky cargo.
• Local Fun Flying (8): Responsive handling, beautiful sight picture, the thrill of retractable gear and V-tail aesthetics. A joy to fly for the experienced pilot.
• Surveying (4): Low-wing limits downward visibility. Fast cruise requires significant power reduction for slow-flight survey work.

Later V-tail Bonanzas typically have well-upgraded panels:

• Basic IFR ($15K-$30K): Garmin GNS 430W/530W, King KFC 200 or Century autopilot, ADS-B transponder. Many S35/V35 models fly with this level.
• Modern IFR ($40K-$80K): Garmin GTN 750Xi/650Xi stack, GI-275 or G5 flight instruments, GFC 500 autopilot, GTX 345 ADS-B In/Out. Popular upgrade path.
• Full glass ($80K-$130K+): Garmin G500/G600 TXi PFD/MFD, dual GTN 750Xi, GFC 600 autopilot, GDL 69A weather, full WAAS/LPV approach capability. Top-tier V35Bs rival new aircraft in capability.

The V35B's instrument panel has good real estate for modern avionics. The ABS provides detailed guidance on panel upgrades specific to each model.

• IO-550 conversion: D'Shannon/Colemill Starfire converts IO-520 to IO-550B (300HP) with four-blade Hartzell Q-Tip prop. Cost ~$79,000 installed. Adds 10-15 KTAS cruise and dramatically improves climb. The most popular performance mod.
• Tip tanks: Add 20-40 gallons, increase gross weight 150-400 lbs depending on model/engine. $12,000-$16,000 installed. Transforms range capability.
• Speed mods: Gap seals ($800-$1,500), cowl closure seals, wheel well fairings. Collectively 5-10 knots improvement.
• Propeller upgrades: Hartzell scimitar props or 4-blade conversions. $8,000-$15,000. Reduced noise, improved efficiency.
• Speed brakes: Precise Flight speed brakes ($6,000-$8,000 installed). Essential for managing the V35B's clean descent profile — it doesn't want to come down.
• Vortex generators: $3,000-$5,000 installed. Improve slow-flight handling and reduce stall speed.
• Air conditioning: Keith Products A/C systems available via STC. $15,000-$25,000 installed.

• Annual inspection: $3,000-$6,000 base, plus any squawks. V-tail-specific inspections (ruddervator AD compliance checks, stabilizer tip inspections) add to baseline cost.
• Parts availability: Good. Textron Aviation continues support. Aftermarket parts widely available through Aircraft Spruce, Wentworth, and specialty Bonanza shops.
• American Bonanza Society (ABS): The gold standard of type clubs. Technical advisors, maintenance forums, BPPP training clinics, and annual conventions. Membership ($80/year) is essentially mandatory for informed ownership.
• Mechanic familiarity: Common. Most experienced A&Ps can work on Bonanzas, though the V-tail ruddervator system, electric gear, and IO-520 fuel injection are somewhat specialized.
• Expensive items: Engine overhaul ($38,000-$55,000), propeller overhaul ($3,000-$6,000), fuel cell replacement ($3,000-$8,000 per side), ruddervator overhaul ($3,000-$6,000), landing gear overhaul ($5,000-$12,000), avionics upgrades (varies widely).

Late V-tail pricing varies significantly by model era and equipment:

• J35/K35/M35 (IO-470): $68,000-$130,000. Lower performance than IO-520 models but more affordable entry point.
• N35/P35 (IO-470N, 260HP): $80,000-$160,000. Good middle ground.
• S35/V35/V35A (IO-520-BA): $120,000-$250,000. The desirable 285HP models.
• V35B (IO-520-BA): $140,000-$320,000. Final production, most refined, highest demand.
• V35B-TC: $150,000-$280,000. Turbo adds some value but also maintenance concerns.

Key value adjusters per valuation-methodology:

• Engine time: Low-time/post-overhaul IO-520 adds $25,000-$40,000 vs mid-time
• IO-550 conversion: Adds $40,000-$60,000 over stock IO-520 value
• Avionics: Full glass panel (G500/GTN stack) adds $40,000-$70,000
• Tip tanks: Add $8,000-$15,000
• Paint/interior: Excellent condition adds $10,000-$20,000
• Ruddervator AD: Full modification compliance (not just inspection compliance) adds value vs limitation-only compliance
• Known icing (TKS): Adds $15,000-$25,000 if installed and serviceable

Critical: Ruddervator ADs (same as beechcraft-bonanza-35-early)

• AD 94-20-04: Mandatory for all C35 through V35B models. Ruddervator inspections, modifications, and operating limitations to prevent V-tail structural failure. This is the most significant ongoing AD for V-tail ownership.
• The AD requires periodic inspections and either compliance with operating limitations (reduced Vne) or completion of specific modifications (ruddervator rebalancing to ≤18 inch-pounds tail heavy) to eliminate the limitations.
• Full compliance is non-negotiable for purchase. Any V-tail without documented complete AD compliance is either unflyable or a deal-breaker.

Other Key ADs:

• Spar carry-through inspection (recurring)
• Fuel cell inspections
• Stabilizer tip inspections
• Landing gear actuator and saddle inspections

Common Problems:

• Magnesium corrosion: Gear doors, some control surface components. Critical inspection item especially in humid/coastal environments.
• Landing gear: Electric motor-driven system is generally reliable but ages. Microswitches, actuators, and downlock mechanisms require attention. Gear-up landings remain the most common Bonanza insurance claim.
• Fuel system: Bladder-type fuel cells deteriorate ($3,000-$8,000 per side to replace). Fuel selector valve and plumbing inspections are important.
• Continental IO-520 issues: Crankcase through-bolt corrosion, cam/lifter wear if not flown regularly, cylinder base stud failures on high-time engines.

Per insurance-underwriting, V-tail Bonanzas are among the most scrutinized piston singles for underwriting:

• Hull insurance: $2,200-$4,500/year for $150,000-$300,000 hull value. Rates vary significantly by pilot qualifications.
• Liability: $1,000,000 smooth typically $500-$900/year.
• Pilot minimums: Most underwriters require instrument rating, 500+ total hours, 50+ retractable hours, and 10-25 hours dual instruction in type.
• V-tail surcharge: 10-20% premium over equivalent straight-tail models (F33A/A36). This reflects the historical loss record, not current structural concerns (which the ADs address).
• BPPP requirement: Bonanza Pilot Proficiency Program completion often required or incentivized with premium discounts (5-10%).
• Open pilot warranty: Restrictive — expect specific named-pilot only or very limited open-pilot terms.
