PT Garuda Indonesia conducted a Station Safety Audit (SSA) of their ground handling provider periodically. In May 2023, the SSA conducted on PT Gapura Angkasa identified the operation of the Baggage Towing Tractor (BTT) with an unserviceable parking brake. This finding was closed by placing the BTT in the workshop. Therefore, the reappearance of motorized GSE operated without a serviceable parking brake after the closure of the finding indicated that the corrective action did not systematically address the finding.The next periodic SSA by the aircraft operator was conducted in April 2024, after the parking brake of the LST had been removed, and there was no finding related to the unserviceable parking brake of the LST. Considering that the BTT and LST were included as motorized GSE, and that the ground handling provider operated only one LST, this indicated that the SSA was ineffective in detecting serviceability deficiencies of motorized GSE. Therefore, KNKT recommends that Garuda Indonesia improve the Station Safety Audit to ensure that the operation of unserviceable motorized GSE can be prevented.
