I took the 16-hour course and hold the light-sport aircraft repairman certificate with an inspection rating and perform the annual condition inspections on the two light-sport aircraft I own. (The N-numbers an individual is authorized to inspect are specified on the certificate.) The 16-hour course will NOT teach you everything needed to perform the inspection. The bulk of the course content is focused on the FAA regulations, the aircraft's required paperwork, and how to legally record the inspection in the logs. Very little of the course covers actual hands-on inspection procedures and techniques. Some of it is hands on, but it is like reading the index of the the encyclopedia you need to know. Armed with the certificate, the determination to seek out and learn more about your aircraft, and the common sense to call in an expert when you're smart enough to recognize you're in over your head, the LSA Repairman certificate is a great thing.
