Dual Actuated Inertial Particle Separator System
(This section applies to Serial Numbers 100-00043 and up OR airplanes
equipped with the KODIAK TKS Ice Protection System.)
The Dual Actuated Inertial Particle Separator (DIPS) system employs two
mechanically linked moveable doors, a xed turning vane, and an ice
shedder, all housed in a berglass composite intake duct. The rst door
pivots about the top forward edge of the duct and the trailing edge comes to
rest on the upper surface of the turning vane in its deployed position. When
stowed, the rst door retracts to serve as the upper surface of the intake duct
immediately prior to the exit from the diffuser section of the air intake system.
The basic function of the rear door (also termed the bypass door) is to block
off the bypass ducts during NORMAL operation (thereby increasing the ram
air recovery), and to direct debris and bypass airow overboard in BYPASS
mode. The gure below shows the basic features of the IPS.

Manual Actuator Override Switch for Dual Actuated IPS
The Inertial Separator on your aircraft is equipped with an actuator override.
This actuator override allows the pilot to advance the system to BYPASS in
the event of a failure of the normal engine inlet BYPASS function.
