Abstract

Airplanes are required to continue to be airworthy. Airworthiness of the aircraft is supported by several systems, one of which is the leading edge flap. The leading edge flap is a lift-increasing component that is included in the leading edge devices and its use is combined with the trailing edge flap to allow the aircraft to operate on a short runway. The use of leading edge devices provides a change in the wing chamber which is useful for increasing lift. This study aims to determine the handling and analysis of Leading Edge Flap Slow Response on Boeing 737-800 NG aircraft at PT. Sriwijaya Air. The method used in this study was to directly observe the events at the Soekarno Hatta Airport Line Maintenance. In addition, researchers also used the fault tree analysis method to analyze the causes of the Leading Edge Flap Actuator Slow Response on the Boeing 737-800 NG aircraft. The results of this study are the presence of dirt attached to the seal and actuator surface so that the seal experiences continuous friction which results in wear of the seal. Actions that can be taken to overcome these problems are by replacing the actuator and functional testing the leading edge flap actuator. Based on the analysis using the Fault Tree Analysis (FTA) method, there were 6 basic events that resulted in the Leading Edge Flap Slow Response.
