A certificated Senior Parachute Rigger applying for an additional type rating must take which of the following tests?

A certificated Senior Parachute Rigger applying for an additional type rating is required to pass a practical test. This practical test is essential because it assesses the individual's hands-on skills, ensuring they are proficient in the specific rigging and packing techniques associated with the new parachute type. Practical testing is critical in this profession, as the safety of parachutists directly relies on the rigger's ability to properly prepare and maintain parachute equipment.

While it might seem that a written test could also be necessary, the emphasis in this context is on demonstrating the practical skills that are directly applicable to the new type of parachute. This aligns with the operational safety standards that govern parachute rigging and creates a benchmark for rigger competency. Hence, the choice of a practical test effectively balances regulatory compliance with the safety requirements of parachute operations.
