Abstract

The ground spoiler on the Boeing 737-800 serves to increase the drag force and reduce the lift force when the plane is landing. There was a problem with the ground spoiler that couldn't go up (extend upwards). The impact of the trouble is that the aircraft requires a longer runway to land which has the potential to overshoot. Therefore, treatment is needed to solve these problems. This study uses the observation method, handling failures using the Aircraft Maintenance Manual (AMM) ATA 27-62-61-020-001 and Fault Tree Analysis (FTA) to determine the causes of failure in the ground spoiler. The results of the study found a leak in the ground spoiler interlock valve due to damage to the seal. While the results of the cause of failure based on the fault tree analysis method in the form of high tension on the speedbrake forward drum, broken seal, leaking seal, friction on the ratio changer, friction on spoiler mixer, loosen, corrosion, and kink.
