FAA AMT Airframe Practice Exam 2026 – Complete Exam Prep Guide

The repair that would require a landing gear retraction test is the replacement of the gear downlock microswitch. This test is necessary to ensure that the landing gear retracts properly after the switch has been replaced. The other options, such as hydraulic fluid replacement, tire replacement, and painting the gear, do not directly affect the functionality of the landing gear retraction system. While these repairs may still be necessary for the overall maintenance of the aircraft, they do not specifically require a retraction test.
