How often must an ELT be inspected under CAR 91?

The requirement for inspecting an Emergency Locator Transmitter (ELT) under Civil Aviation Rules (CAR) 91 is set at intervals of 12 months. This annual inspection ensures that the ELT is functioning correctly and will operate when needed in an emergency situation. Regular checks of the ELT are crucial because they may not be used frequently, and it's vital to confirm that they are in good working condition, with fresh batteries and without any defects.

Maintaining the ELT in this manner aligns with safety practices and ensures compliance with aviation regulations, contributing to the overall safety of flight operations. By adhering to the 12-month inspection requirement, operators can ensure that they are prepared for emergencies, thereby enhancing the safety of their flights.
