PMA parts are required to be marked with information regarding the product on which they are eligible for installation. If the information is too extensive, it may be included in which of the following?

PMA (Parts Manufacturer Approval) parts must adhere to specific marking requirements to ensure they are properly identified for installation on approved products. When the necessary information related to the eligible product is extensive, it can be effectively documented in a readily available catalog. This catalog provides a comprehensive overview of the PMA parts and their compatibility with various products, ensuring that users can easily find the necessary data without cluttering the physical part itself.

The use of a readily available catalog allows for flexibility in including detailed or extensive information that might be impractical to mark on the part, thus maintaining clarity and aiding in proper installation and compliance with regulations. This approach benefits technicians and mechanics by ensuring they have immediate access to pertinent details when working with PMA parts.

Additional sources, like an FAA Form 337, the original type certificate data sheet, and the manufacturer's maintenance manual, serve specific purposes, typically related to documenting modifications or detailing maintenance practices rather than compiling extensive eligibility information for PMA parts. Hence, they are not the best choice for including expansive product eligibility details.
