How many parachutes must a certificated Master Parachute Rigger have packed to apply for an additional type rating?

The correct number of parachutes that a certificated Master Parachute Rigger must have packed to apply for an additional type rating is 20. This requirement is part of the regulatory framework set forth by aviation authorities, which outlines the necessary experience and practical requirements for riggers to expand their qualifications. Verifying that a rigger has packed a sufficient number of parachutes ensures that they possess the necessary skills and familiarity with various types of equipment.

Having packed 20 parachutes demonstrates a level of competency that reflects hands-on experience, which is crucial for safety and professionalism in the field. This number was established to ensure that riggers have not only theoretical knowledge but also practical expertise before they can take on the responsibility of packing more complex systems associated with different types of parachutes or harnesses.

The other options, such as 30, 50, or 100 parachutes, exceed this specified requirement and do not align with the established standards for additional type rating applications. By requiring 20 packed parachutes, the regulation seeks to maintain a standard that balances both safety and accessibility within the profession.
