FAA AMT Airframe Practice Exam 2026 – Complete Exam Prep Guide

Type A rivets are not used under certain conditions because they have low strength characteristics. This means that they may not be able to withstand the required loads and may not be as durable as other types of rivets. This can compromise the structural integrity and safety of the project. The other options listed, such as high cost, high weight, and mismatched color, may also be potential reasons why type A rivets are not preferred, but they are not the main reason as they do not directly affect the performance of the rivets.
