Which of the following is typically found in the identification markings on flexible hoses?

• A. A date code
• B. Length of the hose
• C. The color of the hose
• D. Type of liquid transported

Answer: (A)

Flexible hoses often come with identification markings that include a date code, which indicates when the hose was manufactured or when it was last serviced. This date code is crucial for maintenance and safety, as it helps technicians determine the age of the hose and when it may need to be inspected or replaced. While the length of the hose, the color of the hose, and the type of liquid transported are important aspects of hose specifications, they are not universally included as identification markings. The length may be indicated separately during installation, the color can vary based on the manufacturer or design rather than being a standardized marking, and the type of liquid transported is usually specified on documentation rather than directly on the hose itself. The date code remains a key identifier in ensuring the operational safety of the hose within aviation maintenance practices.
