History of the Flight
On 24 December 2011, a Boeing 737-200 aircraft registered PK-CJD, operated by PT. Sriwijaya Air, was performing scheduled passenger flight SJ 041 from Sultan Syarif Kasim II Airport, Pekanbaru, to Soekarno-Hatta International Airport, Jakarta. The aircraft carried 134 persons: 2 pilots, 4 cabin crew, and 128 passengers (114 adults and 4 children).
Hydraulic System Failure
During the flight, a hydraulic hose installed on the right main landing gear (RH MLG) burst. The burst occurred at the middle section of the hose, as documented in the investigation. The failure led to a loss of hydraulic fluid, affecting the aircraft's hydraulic systems.
Runway Overrun
The aircraft subsequently landed at Sultan Mahmud Badarudin II Airport, Palembang. During landing, it overran the runway and came to a stop in the overrun area (area 11). The aircraft sustained damage, and the investigation documented the final position of the aircraft.
Investigation Findings
The National Transportation Safety Committee (NTSC) conducted the investigation. Tests on the failed hydraulic hose (part number AE2464163E0192) revealed that the wire mesh had fractured due to fatigue and static tensile overload. The fracture characteristics indicated initial fatigue cracks, followed by static rupture. The investigation also examined the hydraulic system, flight data, and maintenance actions. The NTSC's conclusions identified contributing factors, which are detailed in the final report.
