Which of the following aircraft must be maintained in accordance with the "Airworthiness Limitations" section of the manufacturer's maintenance manual or instructions for Continued Airworthiness?

The correct answer reflects the specific requirements for maintaining airworthiness in accordance with the manufacturer's maintenance manual or instructions for Continued Airworthiness. In this case, the Cessna 177B is designed to adhere to certain maintenance standards set forth by Cessna, which includes the "Airworthiness Limitations." This section of the maintenance manual outlines critical maintenance tasks and the intervals at which they must be performed to ensure that the aircraft remains safe and compliant with regulatory requirements.

The "Airworthiness Limitations" section is crucial for ensuring that the aircraft operates safely throughout its service life. It typically includes limitations on the flight control systems, structural components, and other critical areas that can affect safety and airworthiness.

While other aircraft like the Cessna 421C, Piper PA-32-260, and Beechcraft 35 also have their own maintenance guidelines and airworthiness requirements, the Cessna 177B specifically requires compliance with this section as per the manufacturer's maintenance protocols. Each manufacturer may have different stipulations based on the design and operational complexity of their aircraft, and understanding these nuances is key for maintenance and compliance.
