Downside is the needlessly complicated fuel system and a unreliable pressurization system on the early ones (1970 to 1974). The variable system maintains a sea-level cabin up to 9000 feet, then delivers the pilot-selected cabin altitude until a 4.2 PSI differential is reached. The pressurization system is the same as those found in Cessna’s 400-series twins, with a maximum differential of 4.2 PSI providing an 8000-foot cabin up to 20,000 feet. We are learning its peccadilloes as the months go on. Instrument panel of a Cessna 421 Golden Eagle showing the position of the cabin altitude warning light (left of picture, shown in red).

Cessna 421 Description. Cessna 421B w/VG Normal Procedures Starting Engines 1. The P210 pressurization is a rather poor system (Max Diff of 3.35) that was adapted to a highly successful unpressurized airplane. The 414 utilized essentially the same fuselage, empennage, pressurization, and fuel system as the 421 but with the 402’s wings and direct drive engines rated for only 310 hp per side. Cessna offered an automatic pressurization control, which activates and deactivates while climbing or descending through 8000 feet, but more buyers opted for the variable-control system. Consequently, the Malibu pressurization is the absolute best part of the airplane (IMHO), as the airplane was designed originally for pressurization. The pressure of this temperature controlled, sterilized air is then regulated by a valve in the fuselage. gage to the tee fitting. Land immediately. Their broad range of parts include, cabin pressure valves and controllers, modulators, pneumatic relay, gate valves, starter valves and actuators.

A little more digging into my Cessna 404 Flight Safety Manual and I learn: “All Cessnas, except the 421 and 404 series, have nongeared propellers mounted directly to the engine crankshaft. But to look at it, you see more of the 400 series than you do the pressurized 310.
