Cessna 402B/C, 404 & Reims F406
In 1973 Cessna made a signficant change to the model 402B, at least from an appearance point of view: it got rectangular cabin windows instead of oval ones. For the rest the aircraft remained the same. It formed the basis for some other members of the 400 series twins, all with similar cabin windows. The original oval cabin window versions are described separately.
The different versions of the Cessna 400 series with rectangular cabin windows can be distinguished by:
- the length of the fuselage
- the presence of tip tanks
- the shape of the engine nacelles
- the shape of the horizontal stabilisers
Cessna 402B Utililiner/Businessliner
The first Cessna twin with rectangular cabin windows was essentially the same as the Cessna 402B with oval cabin windows. So it has tip tanks.
The Cessna 402C is based on the late models 402B, so with rectangular windows, but has no tip tanks. The wings are similar to those of the Cessna 414A and 421C, as is the higher vertical stabiliser.
Cessna 404 Titan
The Cessna 404 is a stretched version of the Cessna 402B/C, with six rectangular cabin windows. It has geared piston engines (so with a higher drive axis and prop spinner), horizontal stabilisers with dihedral and a sharp, pointed nose. There were three different versions, Titan Ambassador (passenger), Titan Courier (convertible pax/freight) and Titan Freighter (pure cargo). On the outside they appear the same.
Remarks: The US military designation is C-28 and the Swedish military used it as Tp87.
Reims/Cessna F406 Caravan II
Based on the Cessna 404 Reims Aircraft of France developed the Caravan II, which is basically a Cessna 404 with turboprops. It also has a more blunt nose, which makes it look like a Cessna 441. However, the cabin windows of the latter are smaller and more separated. The horizontal stabilisers are attached to the vertical stabiliser, making it a cruciform tail.
Confusion possible with
The Cessna 400 series twins with oval cabin windows can be considered as most likely source for confusion. But on the other hand exactly the cabin windows are a clear recognition point.
They look a lot like each other, but still the differences are big when you know them. The Caravan II has engine exhausts at the side of the nacelle (just after the prop), non-rounded cabin windows and a horizontal stabiliser attached to the vertical stabiliser.
The Beech Queen Air is comparable in size to the Cessna 400 series with rectangular cabin windows, but has square cabin windows. Also the nose of the Cessnas in generally longer and the cockpit windows are different, as are other details.
Piper's entry in the utility twin aircraft class is easily distinguished from the Cessna 400 series twins by the larger rectangular cabin windows with rounded corners. Other differences depend on the exact models you compare.
