Abstract

Marker beacon is one of the navigation systems that used in ATR 72-600 aircraft that included in the instrument landing system. Marker beacon warn pilots that the aircraft has entered a certain distance to the threshold or the end of the runway at an airport. Marker beacon provide an audio and visual indication to pilots during the landing proccess. Receiver is needed to processing data from marker beacon antenna. Damage to the receiver causes data processing to fail so the aircraft's distance warning to the runway threshold does not appear. That fault causes the pilot fail to land the plane properly and safely. Fault of the marker beacon can be identified by identifying and testing the component. The error occurred in the form of loss of marker caused by trouble in the marker beacon receiver so that there is no indication on the instrument in the cockpit. The troubleshooting process is done by replacing it with a serviceable receiver that has the same part number. After replacing the receiver, the test is carried out again to make sure the marker beacon and its components have returned to serviceable conditions. After troubleshooting and retesting, the indication of the marker beacon is in accordance with the Aircraft Maintenance Manual and no faults have appeared again. This shows that the marker beacon and its components have returned to serviceable conditions and can be used again.
