What you will study
Propeller architecture and protection
Trace primary governing, separate overspeed protection, beta feedback and ground-idle controls. Explain affected-side autofeather oil dumping and opposite-side interlock protection, including why TEST does not prove every normal arming prerequisite.
Synchrophasing and diagnostic measurements
Follow pickup timing through controller output to governor trim. Distinguish governing range and capture authority from component faults. Interpret peak-to-peak amplitude, waveform shape, residual vibration and power-dependent vibration difference as separate evidence.
Practice and demonstrate understanding
Eight lessons, six prediction-and-Apply exercises, eight two-stage cases, a required measurement bench and twelve independent decisions provide 24 lab requirements. The independent review requires every critical decision. A separate 40-question final requires 80%; the certificate requires all learning activities.
Learning outcomes
- Explain each control layer and its shared mechanical outcome.
- Separate autofeather dump response from opposite-side interlock and normal arming proof.
- Interpret pickup waveform and vibration records using the applicable source boundaries.
- Connect command, response, restored interfaces and required repeat checks.
Aircraft and course applicability
B300/B300C propeller systems described in supplied maintenance manual 130-590031-11 Chapter 61, including the HC-B4-MP-3 branch and identified serial/noise-reduction differences. Confirm actual propeller, governor, switches, avionics and modifications. Other propellers and later aircraft configurations require their own effective instructions. Beechcraft Super King Air B300/B300C Maintenance Manual 130-590031-11, supplied Chapter 61 effective-page list November 1, 2025. Description pages April 1, 2018; balance/adjustment pages April 15, 2023; synchrophaser check November 1, 2024; autofeather check November 1, 2025.
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.
