This research aimed to identify and detect each existing failure mode based on probability and severity and provide solutions using the Failure Mode and Effect Analysis (FMEA) method. A company known as PT. Gapura Angkasa in Sultan Hasanuddin Airport was used, which has hundreds of workers in the Ground Support Equipment (GSE) Division, and its operation is fraught with danger and risk. This research identified the cause of the GSE damage, ensuring the safety of workers and the smooth operation of the aircraft and passengers. A qualitative approach was used to examine the condition of the equipment, with the researcher serving as the primary instrument. To obtain information about the failure modes of the GSE at PT. Gapura Angkasa Makassar, the FMEA method was used. This was carried out by determining the risk rating, which is represented by the Risk Priority Number (RPN). The results showed that there were two types of GSE damage, namely BTT and BCL. The engine indicator component in the BTT and the steering column in the BCL had the highest damage, with RPN of 240 and 160, respectively. Routine maintenance is recommended on components with a high probability value to improve their reliability, while special attention should be paid to components with a high RPN level.
