True or False: Compression riveters can be both pneumatic and manually operated.

Compression riveters indeed can be both pneumatic and manually operated, making the statement true. This versatility allows for their use in a variety of situations, providing mechanics with different options based on the specific needs of an assembly project.

Pneumatic compression riveters utilize compressed air to provide the force needed to install rivets, which can increase efficiency and reduce physical strain on the operator. In contrast, manually operated compression riveters rely on the operator's muscle power to apply the necessary force. This can be beneficial in certain scenarios where air supply might not be readily available or in environments where simplicity of operation is prioritized.

Combining both types allows for flexibility in different workflows and environments where aerospace assembly mechanics might operate, ensuring that they can choose the best tool for the job at hand.
