Textbook and current syllabus

The supplied PDF is Module 07A, version 003 (2019). Its chapters 4 and 15 remain useful reference extensions. Current EASA reserves 7.4 and 7.15 and adds 7.14.3 additive manufacturing and 7.21 documentation/communication, covered by chapters 21โ€“22. DGCA candidates should use the applicable CAR-66 and examination-provider requirements. See the source map โ†’
