10.1 Engine cowling
The engine cowling is comprised of an upper and lower cowl segment. Quick-release screw
fasteners are used at the cowling to fuselage attachment points fixing the cowling to the firewall. Quick-
release screws are also used along the side surfaces to hold lower cowling and upper cowling segments
together. Both cowl segments are constructed from carbon fiber composites.
10.2 Removal and installation
11.2.1 Required Tools: Screwdriver
11.2.2 Parts required: None
11.2.3 Level of Maintenance: Light
11.2.4 Certification required: Owner
Removal and installation of engine cowling is accomplished by initially releasing the quick-release
fasteners at the side surfaces. Then, remove the upper cowling by disengaging it from top of the fire wall,
then lifting the upper cowling away from the lower cowling from the front of the aircraft. Disconnect the
Carburetor heater controls (see figure 10-1, N. 1), the orange air intake tube (N. 2), the oil cooler
connections (N. 3), release the oil cooler but do not disconnected oil hoses, and disconnect the water
cooler holder (N. 5, 6)
Loosen the quick-release screws of the lower cowling segment (N.8) and remove from the front
of the aircraft. Take care to disconnect the electrical wiring to the landing light in lower cowling (if installed
N.7) when removing the lower cowling.
When reinstalling the cowlings
– reverse the above process.
