About the Cessna 421B

The Cessna 421B Golden Eagle is an eight-seat, twin-engine, pressurized piston aircraft with turbocharged Continental GTSIO-520 engines. Burning approximately 34 gallons per hour total, the 421B offers a pressurized cabin and genuine business-class comfort in a piston twin.

Variable hourly costs average around $420, with annual fixed costs near $42,000. The 421B appeals to operators who need pressurized twin-engine capability without stepping up to turboprop economics, and to pilots who value the cabin comfort of business aviation at piston prices.

Cessna 421B Price & Cost

Cessna 421B Price Guide

Key price factors: engine time to overhaul, year and airframe hours, avionics, damage history and logbook completeness — see the buying guide below for the full pre-purchase checklist.

Cessna 421B Cost of Ownership estimate
Fuel (34.0 GPH × $6.20, 100 hrs)$21,080/yr
Annual Fixed (hangar, insurance, annual)$42,000/yr
Variable (per hour)$420/hr
Engine Overhaul (every 1,600 hrs)$48,000
Estimates at 100 flight hours/year. Actual costs vary by usage, location and insurance.

Buying a Used Cessna 421B

Every Cessna 421B faces a mandatory 1,600-hour overhaul, so the single biggest factor in used price is how much time remains before that overhaul is due — a fresh-overhaul airframe can be worth a large share of the $48,000 overhaul cost more than one approaching its limit.

What to check before buying

  • Time to overhaul — hours and years remaining to the 1,600-hour limit; this dominates resale value more than total time.
  • Logbook completeness — continuous, gap-free maintenance records; missing logs cut value and complicate financing.
  • Damage history — any prior accident, hard landing or blade strike; cross-check the registration against accident databases.
  • Avionics — a glass panel vs steam gauges materially changes price.
  • Pre-buy inspection — always commission an independent inspection by a type-experienced mechanic before money changes hands.

Frequently Asked Questions — Cessna 421B

Why is the Cessna 421B called a money pit?
The geared Continental GTSIO-520 engines have short TBOs (1,200-1,600 hrs), expensive overhauls ($47K+ each), and require gentle throttle management to avoid crankcase cracking. The exhaust system is prone to cracking and has been implicated in fatal fire incidents. Annual inspections run $15-20K at a specialist. A viscous damper AD (2007-05-15) addresses a failure mode that can destroy the engine.
Who should buy a Cessna 421B?
Buyers who need a pressurized cabin-class twin for under $200K acquisition and have access to a twin Cessna specialist shop, budget for $20K+ annual maintenance, and the discipline to manage geared engines properly. Treated well, the GTSIO-520 will reach TBO. The 421B carries 6 passengers in a stand-up cabin at 200+ knots — hard to match at the price.
Cessna 421B vs. 421C — which is better for buyers?
The 421C (1976-1985) added bonded wet wings (eliminating tip tank plumbing), improved pressurization, and the GTSIO-520-L engine with better TBO history. The 421C commands $50-150K more but is worth it for reduced fuel system complexity and better corrosion resistance. The 421B is cheaper but requires more vigilant maintenance of its tip tank fuel system.
