When applying for an additional type rating, how many parachutes must a certificated Senior Parachute Rigger have packed?

A certificated Senior Parachute Rigger must pack at least 20 parachutes of the specific type for which they are seeking an additional rating. This requirement ensures that the rigger possesses a substantial amount of hands-on experience and competence with the parachute type, demonstrating their ability to pack it correctly and safely. By mandating the packing of 20 parachutes, regulatory authorities can help ensure that riggers are well-versed in the nuances and specific requirements of different parachute types, which can vary significantly.

This threshold of 20 parachutes represents a balanced approach to ensuring safety and expertise in the field of parachuting, as it allows riggers to gain necessary practical experience without being overly burdensome.
