Description

This beautiful 1977 Cessna 421C model shows as a well-cared-for aircraft and as a great example of an 8-passenger piston twin that in this price category has no equals! It can carry a pilot and 7 passengers in pressurized comfort, high above the weather, and go faster and farther with more comfort than anything else in this price range. The Cessna 421C is often referred to as the Rolls-Royce of piston twins. This aircraft is registered in an LLC in Montana for tax reasons, and we would consider selling the LLC for $1.00 along with the sale of the aircraft. It would be a big savings for a new Buyer! We also will look at trades, other aircraft, collectible automobiles, etc. A very complete and timely Annual inspection was completed, along with a completely new interior. The Annual inspection included new brakes, rotors, calipers, and brake pads. A new main battery, new tires, a refurbished right nacelle extra fuel tank, which gives N6633T a total fuel capacity of 262 gallons, and other new items that are associated with 421C Annuals. In the past five years, N6633T has received a new tinted, heated pilot's windshield, a new co-pilot's windshield, and all new side windows. All of the windows are in great condition!

Modifications

These engines are the Continental GTSIO-520-L 375-horsepower engines. Until just a few months ago, A Chinese company was the owner of Continental Motors and was slow in supplying parts for these engines, and that was a little bit of a problem for engine re-builders. That has been solved by a U S company buying Continental Motors back from the Chinese and producing and delivering engine parts promptly.
