EASA part 66 requirements
EASA has set standards for certifying personals under part 66. One who wants to acquire an EASA part 66 license must satisfy the competent authority that he has adequate knowledge.
EASA part 66 demands the applicant to satisfy the theoretical and practical knowledge. Theoretical knowledge is demonstrated by passing the required EASA part 66 modules exams while the practical knowledge is demonstrated by submitting an experience logbook. The logbook must have complete details of the tasks performed, including the type of aircraft and job card number. Check out the details for the knowledge and experience requirements for each category.
