24. Question : Course testing (not FAA exams), including preparation and post-test reviews, is an important part of the learning process. Are these activities part of the minimum 1,900 hours?
Answer: Yes. This is very clear. Reference AC 147-3, Paragraph 12g(3) and FAA Order 8300.10 Airworthiness Inspector’s Handbook, volume 2, Chapter 187, Paragraph 7. The rule states, however, that time spent to prepare or review for the FAA general, airframe, or powerplant test may not be included as part of the hours to satisfy a school’s approved curriculum requirements.
