Flying below the minimum safe altitude is contrary to the Indonesia regulation and AAA procedure and hazardous especially if any obstacles surround the flight path. The Garmin G1000 data log of two AAA aircraft within period of four months prior the PK-WUG accident recorded 17 training flights flying below the minimum safe altitude. These low flying were not detected as the AAA had not established systems to monitor the movement of aircraft or to review and analyze the available data, such as Garmin G1000 data log.After the accident, the AAA installed ADS-B receiver in the Cirebon flight operation office to enhance the capability to retrieve ADS-B data in order to monitor the movement of aircraft in real time. The AAA had developed Standard Operation Procedure (SOP) of flight following activities which requires dedicated personnel to monitor flight activities using ADS-B-based flight tracker application. However, the procedure did not describe requirement to conduct immediate corrective action when deviation from requirement standard has been detected during flight training activity.Therefore, KNKT recommends the AAA develop system to monitor the training activity using the available means to detect flight training activity that deviate from the requirement standard and to enable immediate corrective action.
