In which category must an aircraft be to perform spins?

To perform spins, an aircraft must fall under the Utility category. This classification allows for a higher level of aerobatic maneuvering compared to the Normal category, which is designed primarily for general flying operations with limits on the type of maneuvers that can be performed. The Utility category encompasses aircraft that are approved for limited aerobatics, such as spins, provided they meet certain performance and design criteria.

Aircraft in the Normal category are restricted from performing spins due to safety concerns, as they are not designed to withstand the structural stresses that can occur during such maneuvers. The Experimental and Restricted categories also have their specific purposes and regulations. Experimental aircraft may be used for testing and may have different criteria depending on the type of experimental use, while Restricted aircraft are usually limited to specific operations such as agricultural or firefighting activities.

Therefore, the Utility category’s approval for spins aligns with the design considerations and operational flexibility that these aircraft are intended to provide.
