Air Intakes (if MÄM 42-600 is installed)
1. General
An air filter housing, air filter and alternate air valve assembly make the engine air intake system of the
DA 42 NG (if MÄM 42-600 is installed) airplane. The air filter box is connected to the intercooler air
intake duct via bolts. A flexible hose feeds the air from the alternate air valve to the turbo-charger.
A lever below the instrument panel (right-side) operates both (LH and RH) alternate air valves
simultaneously.
Figure 1 shows the engine air filter and alternate air valve.
2. Description
The air intake has 4 main parts:
)
Alternate air valve assembly.
)
Air filter housing.
)
Air filter.
)
Alternate air valve operating cables.
A. Alternate Air Assembly
Refer to Figure 1. The alternate air valve is attached to the aft face of the air filter housing. The air
filter attaches to the front of the alternate air valve. The alternate air valve also has an inlet direct
from the engine compartment. Rotary motion of the outer ring opens different holes to the engine
compartment. So the valve can select either fresh filtered air or unfiltered air from inside the
cowling.
B. Air Filter Housing
The air filter housing is made of CFRP. It is installed directly to the intercooler / engine air intake
duct via bolts.
C. Air Filter
Refer to Figure 1. The air filter is a high-flow air filter. The air filter is located in the middle of the
engine compartment, just forward of the firewall in the air filter box.
