AS350/H125 Helicopter Continuation/Refresher Training Syllabus

ABOUT

This course provides continuation/refresher training for the Airbus AS350/H125, structured to meet ATA 104 Specification Level I and EASA Part 66 Level 1 requirements. This self-study course consists of approximately 40 hours of study, with multiple-choice questions at the end of each ATA chapter. Students must pass each question block to unlock subsequent chapters. Upon successful completion, a certificate of completion will be issued.

Course Objectives

Upon completion of the course, students will be able to:

1. Identify safety precautions specific to the airframe, systems, and powerplant of the AS350/H125.
2. Outline maintenance practices for the helicopter’s systems.
3. Understand the configuration of major helicopter systems and powerplant components.
4. Identify required special tooling and test equipment for the AS350/H125.
