How do I obtain privileges to operate an additional category or class of aircraft?

This regulation explains how sport pilots (or higher certificate holders) can add new categories or classes of light-sport aircraft to their privileges.

For most additional categories/classes (like weight-shift control, powered parachute, glider, or airship), you need:

• Training and a logbook endorsement on the required knowledge and flight skills
• A proficiency check with a *different* instructor than the one who trained you
• A logbook endorsement from the proficiency check instructor certifying your competency

However, if you want to add airplane single-engine land or sea, or rotorcraft-helicopter, the process is different—you must take a full practical test (checkride) as described in §61.307(b), not just a proficiency check.

This matters because it determines whether you need a formal FAA practical test or can use the simpler proficiency check process to expand your flying privileges within the sport pilot category.
