FAA Powerplant Written Practice Test

Which statement is true regarding the certification of light sport aircraft engines?

1. All light sport aircraft engines are certified by the FAA

2. No light sport aircraft engines are certified by the FAA

3. Some light sport aircraft engines are certified by the FAA

4. Certification of light sport aircraft engines is optional

The correct answer is: Some light sport aircraft engines are certified by the FAA

The statement indicating that some light sport aircraft engines are certified by the FAA is correct as it acknowledges that while not all engines used in light sport aircraft must go through FAA certification, many do. The FAA has established standards for aircraft engines, and manufacturers may choose to have their engines certified to these standards to ensure safety, reliability, and compliance with regulatory requirements. It is important to understand that the Light-Sport Aircraft (LSA) category is designed for aircraft with specific limitations that can operate under a simplified certification process. This includes the possibility for manufacturers to produce engines that either conform to accepted standards or are developed based on ASTM standards. Therefore, while certification is not mandatory for all engines used in light sport aircraft, it remains a valid route for some manufacturers who decide to certify their engines to provide an added level of assurance to users. It supports the overall integrity of the light sport aircraft environment and can be advantageous for the manufacturers in establishing a reputation for quality and safety.
