PLENUMS & SCREENS
Inside each engine air intake, there is a
plenum chamber which stabilizes and
directs the airflow to the engines' air inlet.
Protective screens are mounted to the
front side of the forward firewall to prevent
ingestion of debris. There is adequate
space inside the plenums to replace the
screens with the optional
engine air
particle separator kit when operations are
conducted in dusty environments.
ENGINE AIR INTAKES
Air intakes are provided for engine operation, engine compartment cooling, and for
engine / transmission oil cooling. Two engine air intakes are located at the top of the air
induction cowling, one on either side of the transmission. Cooling air for the engine
compartments and oil coolers is inducted through two recessed scoops located on the
left and right lower engine cowls.
