What is the minimum supervised work experience required for ET hours before performing inspections without direct supervision?

The minimum supervised work experience required for ET (Electronics Technician) hours before an individual can perform inspections without direct supervision is indeed 40 hours. This requirement is crucial as it ensures that technicians have sufficient hands-on training and exposure to actual work conditions, allowing them to become familiar with inspection procedures and the specific systems they will be responsible for inspecting. This experience is designed to build competence and confidence in their ability to conduct thorough and accurate inspections on their own.

Having a designated number of hours ensures consistency in training and helps maintain safety and quality standards within aviation maintenance. The 40-hour requirement strikes a balance between providing adequate training while also ensuring that individuals are adequately prepared to take on these responsibilities independently.
