Flight History
On 27 March 2013, a Boeing 737-500 aircraft registered PK-CLJ, operated by PT. Sriwijaya Air, was operating scheduled passenger flight SJ 021 from Polonia Airport, Medan to Minangkabau International Airport, Padang, and onward to Soekarno-Hatta International Airport, Jakarta.
Prior to departing the hotel in Medan, the pilot in command (PIC) reported a stomach ache and was observed visiting the toilet several times during the flight from Medan to Minangkabau.
Sequence of Events
Upon arrival at Minangkabau, during taxi to the parking position, witnesses reported that the aircraft taxi speed was faster than normal. The Flight Data Recorder (FDR) recorded a taxi speed of 18 knots. The aircraft stopped approximately 4 meters beyond the marking line, with the left wing near and almost touching the aerobridge. The marshaller stated that he had given a stop signal, but the aircraft continued moving. The aircraft was then pushed back to the correct position, and all passengers disembarked.
No hazard report was filed by Sriwijaya Air or Minangkabau staff regarding this occurrence.
Later, when approaching the threshold of runway 15 for line-up, the pilot turned the aircraft left. The aircraft stopped on an approximate heading of 270°, with the nose wheel located about 4.2 meters off the runway and at full left deflection. A 22-meter rubber skid mark from the nose wheel was found on the runway, beginning from the centerline guide to the stopping point.
Flight Recorder Data
The FDR revealed that during the initial turn for line-up on runway 15, the aircraft taxi speed was 21 knots.
Aircraft and Systems
No discrepancies were reported with the aircraft or the runway lighting system prior to or during the serious incident.
