Kind of exciting from a pilots standpoint, this section is where all the control cables are installed including

• Throttle cable
• Propellor cable
• Mixture cable
• Alternate Air cable
• Exhaust cooling or cowl flap cable
• cabin heat cables

I bought a custom overlay to go over the cable bracket with labels identifying the function of the cables. The FAA may or may not require this type of labeling so I went with it just in case.

The other end of the throttle and mixture cables attached to the fuel servo (throttle body):

This shows the prop cable (that controls the pitch of the prop) attached to the propeller governor.

The alternate air cable is attached to a cover that can be opened from the cockpit. The purpose of this is if the air filter (covered in plastic in previous photo) gets iced up when flying through clouds, I can open this cover, which is inside the cowl and next to the engine. Then air will continue to flow to the engine which is kind of vital for engine operation.

The cowl flap sits under the fuselage, and by opening this, more cooling air will flow. It is usually open during takeoff and climb but closed during cruise and landing.
