The purpose of this paper is to determine the optimal procedure for the repair and maintenance of the Garmin GDU-620 applied to the aircraft DA20C-1 for the basic training and training of future pilots of the Ecuadorian Air Force. The aircraft has a Garmin GDU-620 as part of the Garmin G500 integrated system where it presents all the information of navigation instruments and map types, this is formed by two screens PFD (Primary Flight Display) and MFD (Multi-Function Display). This system usually shows faults while night flights were made, once analyzed the faults that are presented in the GDU 620 system, the preventive and corrective maintenance actions are executed, such as maintenance of the internal and external electronic connectors, maintenance of the electronic cards, adequate reconnection of data buses. Later it was installed in the aircraft, where it was evident that the discrepancies were solved and the operation of the equipment in question was carried out without incident. If these discrepancies of failure appear in the GDU-620 equipment displays, it is recommended that the same preventive and corrective maintenance work be performed in order to resolve the discrepancy.
