Baron 58
Serial TH 773 and After
The BEECHCRAFT BARON 58 is powered by two
ContinentaIIO-520-C or IO-520-CB six-cylinder. horizontally
opposed. fuel-injected engines rated at 285 hp at 2700 rpm.
POWER PLANT CONTROLS
PROPELLER, THROTTLE, AND MIXTURE
The control levers are grouped along
the upper face of the
control console. Their knobs are shaped so they can be iden-
tified by touch. A single controllable friction knob below and
to the left of the
control levers prevents creeping.
INDUCTION AIR
Induction air is available from filtered ram air or alternate
air. Filtered ram air enters from the intake air scoop on top of
the cowling. Should the filter become obstructed, a spring-
loaded door on the alternate air intake will open auto-
matically and the induction system will operate on alter-
nate air taken from the engine accessory section.
ENGINE ICE PROTECTION
Engi ne ice protection consists of electrothermal fuel vent
heaters controlled by a switch on the left panel, and an
automatic alternate air induction system.
The only
significant ice accumulation is impact ice on the
inlet scoop and filter. Should the induction air scoop or filter
become clogged with ice, a spring-loaded door on the fire-
wall will open automatically, and the induction system will
operate on alternate air.
