Cessna 421 Golden Eagle

What the Cessna 421 Golden Eagle Is

The Cessna 421 Golden Eagle is a pressurized, twin-engine piston aircraft that Cessna developed from the unpressurized Cessna 411. The company first built it in May 1967 and certified it on May 1, 1967.

It was an immediate hit, with 200 aircraft sold in its first year. It sat at the top of the Cessna piston-twin line, above the unpressurized 401, 402 and 411, and shares one type certificate with them and with the 414 and 425.

The full specification table for the aircraft is on this page. The sections below explain what the numbers mean in practice.

Cessna 421 Variants: 421, 421A, 421B and 421C

Four versions were built, and each fixed something the last one lacked.

• 421 (1967): 375 hp Continental GTSIO-520-D engines, fuel carried in “Stabila-Tip” tanks on the wingtips, and electro-mechanical landing gear like the Cessna 310. Cessna built 200.
• 421A (1968): a three-inch fuselage stretch, five more gallons of fuel and 40 lb more gross weight. Cessna built 158.
• 421B (1970): a heavier airframe, two feet more wingspan that raised the service ceiling by 5,000 ft, and a nose stretched two feet for a bigger baggage compartment. This is the version sold as the Golden Eagle and Executive Commuter, with 699 built.
• 421C (1975): a new wing with wet-wing fuel tanks in place of the wingtip tanks, and a trailing-link landing gear from the 1981 model year. Cessna built 859, and production ended in 1985.

An icing-protection equipment package was offered from 1975, which let owners fly into known icing conditions.

Cessna 421 Range and Speed

The 421C’s published range is 1,487 nm (1,710 mi), flown at 25,000 ft at economy cruise. That is well beyond what most small piston aircraft can fly.

The top speed is 256 kt (295 mph) at 20,000 ft. The normal cruise speed is 240 kt (276 mph) at 25,000 ft and 75% power, so the rated top speed is only a little faster than everyday cruise.

Both figures come from the 1976-77 edition of Jane’s All the World’s Aircraft, which is the data most references repeat. A tired airframe with older engines will do less.

Why the Golden Eagle Flies So High

The 421 is pressurized and turbocharged, so it can cruise high where the air is smooth and the winds are strong. The service ceiling is 30,200 ft (9,200 m).

The cabin is pressurized with outside air. The cabin is quiet for a piston twin, because the engines make their power at low propeller speeds.

Cessna 421 Engines: Geared and Turbocharged

Every 421 uses two Continental GTSIO-520 engines rated at 375 hp each. These are geared, turbocharged, fuel-injected flat-six engines, and the “G” in the name is the gearbox.

The propellers turn slower than the engines, which is why the aircraft is quiet. It is also the part owners respect most, because the gearbox and turbochargers punish abrupt throttle changes. Pilots on forums say that most of the engine trouble they see comes from heavy-handed power reductions.

The related Cessna 414 Chancellor uses direct-drive engines with less power. That makes it a smaller-engine airplane without the 421’s gearing. Some 421s were later converted to turboprop power, which makes them close to the Cessna 425.

Cabin and Seating

Jane’s lists the basic 421 with six seats. Later variants were sold with up to ten, and the 421B and 421C are often sold as eight-seat Executive Commuter aircraft.

The cabin door is on the left side behind the wing. The round cabin windows were made larger in 1975 along with a wider cabin and an improved pressurization system.

Cessna 421 vs Cessna 414

The 421 is the pressurized, geared-engine twin with the higher ceiling and the faster cruise. The 414 is a smaller-engine variant that shares the 421’s type certificate and uses direct-drive engines.

What Does a Cessna 421 Cost?

Used prices depend heavily on the variant, engine time and avionics, so there is no single figure. Check current listings before you buy.

Engine and turbocharger condition matters most, because the geared engines are the expensive part of the airplane.

Safety Record

The 421 has been involved in a number of fatal accidents over its long career. Examples listed on Wikipedia include the 1980 crash that killed Portuguese Prime Minister Francisco de Sá Carneiro, and a 2003 crash caused by a fatigue fracture in a propeller.

The NTSB blamed a 2017 engine fire shortly after takeoff on a fuel leak onto a hot turbocharger. Several of the others involved pilot error in poor weather or on instrument approaches.

Frequently Asked Questions

Which small planes can fly a thousand miles or more?

The Cessna 421C is rated for a range of 1,487 nm (1,710 mi), so a trip of that length is within its published range.

What is the difference between a Cessna 414 and 421?

Both share a type certificate, but the 421 is pressurized with geared, turbocharged 375 hp engines. The 414 is a smaller-engine variant with direct-drive engines.

What is the average cost of a Cessna 421C Golden Eagle?

There is no single average, because prices vary with engine hours, avionics and condition. Look at current listings for the best guide.

Which Cessna 421 is called the Golden Eagle?

Some pilots argue that only the 421C carried the name from the factory, while Wikipedia lists the 421B as the Golden Eagle. In everyday use, owners call every model a Golden Eagle.

How many Cessna 421s were built?

Production ran from 1967 to 1985 and totalled roughly 1,900 aircraft. Wikipedia counts 200 original 421s, 158 421As, 699 421Bs and 859 421Cs.
