This lesson trains the trainee to perform a full pre-operation inspection of a towable stairs unit. It emphasizes identifying defects, ensuring equipment readiness, and maintaining operational safety before use on the apron. The session builds systematic inspection habits and reinforces awareness of how of how major and even minor faults can compromise safety and cause delays.
