Part-21 and Part-26 familiarisation: distinguish design approval, production conformity, release evidence, installation eligibility, certification bases and the current aircraft certificate routes. Includes the August 2026 amendments in Regulations (EU) 2026/56 and 2026/100 and their relationship to AMC/GM. 15 sections include 45 scenario decisions with immediate explanatory feedback. The 12 classroom-equivalent hours are a planning estimate, not measured seat time or a regulatory minimum. Completion does not confer a licence, approval or organisational authorisation. Practice is optional and ungraded; no written submission or upload is required. The final assessment draws 12 questions from a 24-question bank, with 75% (9 correct answers) required to pass.

This online aviation training course is designed for controlled seat assignment, recorded trainee progress, final assessment, and certificate issue after passing.
