FAA Powerplant Written Practice Test

How are Great Plains engines for light sport aircraft typically assembled?

1. Completely assembled by the manufacturer

2. Assembled in the field from manufacturer kits or by the manufacturer

3. Only by certified mechanics

4. Using parts sourced from various suppliers

The correct answer is: Assembled in the field from manufacturer kits or by the manufacturer

Great Plains engines for light sport aircraft are typically assembled in the field from manufacturer kits or by the manufacturer. This assembly method allows for greater flexibility and customization based on the specific needs and configurations of the aircraft. When manufacturers provide kits, it includes all the necessary components that meet regulatory standards while enabling builders or mechanics to complete the assembly process in a controlled environment, ensuring that the engine is tailored to the specific requirements of the aircraft it will power. This approach not only promotes hands-on involvement for builders but also simplifies maintenance and repair processes since the assembly can be done closely in conjunction with the aircraft. In contrast, completely assembling by the manufacturer limits the involvement of builders and potentially increases the cost and complexity for end users who may want to engage more directly with the assembly of their aircraft. Building exclusively with certified mechanics might restrict the options available to aircraft owners, especially in the light sport category, where the emphasis is on simplicity and accessibility. Lastly, sourcing parts from various suppliers does not guarantee the same level of uniformity and conformity to airworthiness standards, which is especially critical in aviation. Therefore, the kit assembly method emphasizes collaboration between the manufacturer and aircraft builders, fostering a community-based approach to building light sport aircraft engines.
