NOTE: Training Courses are generally offered in two (2) formats. BASIC: typical large group, 'lecture/class room' type with books, samples, displays, and visuals. 'MAINTENANCE MENTOR': a small (5-6) mechanic group that repairs 'inoperative equipment' with your shop tools under the Trainer's close supervision. Consequently, your mechanics work, get trained in the process, your most troublesome equipment is repaired, and then returned to revenue service in 'good working order'!
