Garuda Indonesia Flight GA 258 Runway Excursion at Yogyakarta (PK-GNK)

Incident Overview and Flight Details On 1 February 2017, PT Garuda Indonesia operated flight GA 258, a scheduled passenger service from Soekarno-Hatta International Airport in Jakarta to Adisutjipto International Airport in Yogyakarta. The aircraft was a Boeing 737-800 with registration PK-GNK. The flight carried two pilots, five flight attendants, and 119 passengers, comprising 115 adults and four infants. The Pilot in Command served as the Pilot Flying, while the Second in Command served as the Pilot Monitoring. No technical system abnormalities were reported or recorded before departure or up to the time of the occurrence. ## Approach and Landing Sequence The aircraft departed Jakarta at 1742 local time (1142 UTC). The approach was initially uneventful. At 1243 UTC, the Yogyakarta approach controller instructed the crew to fly heading 280° for vectoring to the Instrument Landing System (ILS) for runway 09. Shortly after, the controller instructed a right turn to heading 030° and issued clearance for the ILS approach. At 1245 UTC, the instruction was revised to maintain heading 050° and reduce speed due to traffic. One minute later, the pilot reported the aircraft was established on the ILS localizer and was instructed to contact the tower. At 1247 UTC, the pilot advised the tower that the localizer was established. The tower reported surface winds from 230° at 7 knots and a QNH of 1,010 mbar, instructing the crew to report when runway 09 was in sight. At 1249 UTC, at approximately 1,000 feet, the pilot reported the runway in sight and received landing clearance. ## Occurrence and Aftermath At about 1250 UTC, the aircraft touched down slightly to the right of the runway 09 centerline. As it approached taxiway N2 while applying reverse thrust, the aircraft veered to the left. It came to rest on the left shoulder of runway 09, approximately 1,600 meters from the beginning of the runway and 20 meters from the runway edge. The weather at the time of landing was slight rain. There were no injuries to persons and no damage to the aircraft. ## Investigation Status The preliminary report was issued by the Komite Nasional Keselamatan Transportasi (KNKT). The investigation was ongoing and was to include details from flight recorders, related procedures, human factors, flight technique, and aircraft systems. Prior to the preliminary report, KNKT was informed of safety actions taken by PT Garuda Indonesia. KNKT issued a safety recommendation to PT Angkasa Pura I Branch Office Adisutjipto International Airport to address identified safety issues.
