What you will study
Separate the protection systems and find their controls
Identify what removes existing ice, what prevents ice, and what reports an icing condition.
Follow service air through the EFCVs and timed boot groups
Trace the air supply, explain inflation and vacuum hold-down, and predict each phase.
Check boots, preserve their surfaces and restore the pneumatic system
Recognize a qualified boot check, find the connection, and keep testing, cleaning and winterization separate.
Move and rig the inertial-separator doors
Distinguish commanded bypass from completed door movement, with the correct serial-specific rigging.
Follow engine-inlet exhaust heat through both hoses
Identify the actual heating medium and restore the inlet hose installation correctly.
Prove pitot, static-port and AOA heat individually
Keep the heater current, physical temperature and selected switch state separate.
Map windshield zones to their actual controllers
Predict ground and flight heat behavior and investigate the correct zone and controller.
Measure alternating propeller heat and brush condition
Follow the timer/shunt/heater path and distinguish running functional tests from isolated brush inspection.
Interpret the ice detector, visual cues and test lights
Separate detected icing, a detector fault, the selected protection configuration and illuminated observation areas.
Assess windshield rain repellency and close out the complete task
Prepare a valid mist-spray comparison, interpret actual droplet patterns and preserve a useful maintenance record.

Aircraft and course applicability
Model 408 SkyCourier optional pneumatic deicing; inertial separators and exhaust-heated inlets; air-data, windshield and propeller electric heat; advisory ice detection and windshield rain-repellent inspection. Freight/passenger access and unit -0028-and-on inertial-separator rigging differences are identified. Supplied 408MM13 Chapter 30 list of effective pages April 1, 2025, with specifically referenced Chapter 36 service-air tasks. Confirm actual serial, installed options and complete current instructions for aircraft work.
WWAOG provides independent training. Online completion records knowledge and simulation achievement; it does not replace observed practical qualification, employer authorization or applicable licensing. Use current aircraft-effective maintenance instructions for physical work.
