In order to obtain an airframe and powerplant (A&P) certificate, students must receive a minimum of 1,900 hours of instruction from an FAA approved 14 CFR Part 147 School. Within Part 147, students are only required to learn about helicopters at a level 1 proficiency, which requires only classroom lectures. In order to fill this possible gap in knowledge, the authors created a training exercise at the sophomore level. A helicopter tail rotor was simulated using CATIA to model common stresses on helicopter components. Additionally, helicopter accident reports were used to increase the understanding of proper maintenance, and how components can affect the failure of the rotary system. Through the exercise, students are expected to improve their knowledge of rotary assemblies, while simultaneously expanding their comprehension of statics. As students progress through their Part 147 training, they can apply their understanding of flight-critical components while making inferences on safety and procedures.
