POWER PLANT
1. GENERAL
This chapter describes maintenance practices for the airplane systems which provide the means to induce
and convert fuel-air mixture into power such as the engine, air intake, mount, cowling, and attach fittings.
2. DESCRIPTION (See Figure 71-001)
The SR22 is powered by a Teledyne Continental IO-550-N, six-cylinder, normally aspirated, fuel-injected
engine rated to 310 hp at 2700 RPM. Dual, conventional magnetos provide ignition.
The engine is bed-mounted on a tubular steel weldment which incorporates four dynafocal mount fittings.
The mount fittings use conventional elastomeric isolators. The engine mount is bolted in four locations to
the composite fuselage firewall.
Sheet metal baffles are installed on the engine to direct the air flow around the cylinders and other engine
compartment components. To help direct and contain air flow in the engine compartment, the baffles utilize
fiber reinforced silicon seals in contact with the cowling around the circumference of the engine.
