TRANSPORTATION SAFETY COMMITTEE Aircraft Serious Incident Investigation Report
ISBN: When the NTSC makes recommendations as a result of its investigations or research, safety is its primary consideration. However, the NTSC fully recognizes that the implementation of recommendations arising from its investigations will in some cases incur a cost to the industry. Readers should note that the information in NTSC reports and recommendations is provided to promote aviation safety. In no case is it intended to imply blame or liability. This report was produced by the National Transportation Safety Committee (NTSC), Karya Building 7th Floor Ministry of Transportation, Jalan Medan Merdeka Barat No. 8 JKT 10110, Indonesia. The report is based upon the investigation carried out by the NTSC in accordance with Annex 13 to the Convention on International Civil Aviation, Aviation Act (UU No.1/2009), and Government Regulation (PP No. 3/2001). Readers are advised that the NTSC investigates for the sole purpose of enhancing aviation safety. Consequently, NTSC reports are confined to matters of safety significance and may be misleading if used for any other purpose. As NTSC believes that safety information is of greatest value if it is passed on for the use of others, readers are encouraged to copy or reprint for further distribution, acknowledging NTSC as the source.

1 SYNOPSIS On 1 June 2008, an Airbus A320 aircraft, registration PK-YVE, was being operated by Metro Batavia Airlines (Batavia Air) flight number 7P-591, on a scheduled passenger flight from Jakarta to Medan. The flight departed at 00:10 UTC (07:10 local time) with an estimated arrival time at Medan of 02:25. There were 140 people on board; two pilots, five cabin crew, and 133 passengers. The aircraft touched down towards the departure end of the touch-down area of runway 05 at Polonia Airport, Medan at 03:04. After a landing run of 41 seconds, the aircraft stopped on the runway adjacent to taxiway ‘D’, approximately 1,200 meters from the estimated point of touch down. Three main-wheel tires and two main wheels were substantially damaged. The aircraft could not be taxied from the runway to the apron, nor could it be towed to the apron due to damage to the wheels. The passengers and crew disembarked normally at taxiway ‘D’; there were no injuries. Following an inspection of the landing gear and replacement of the damaged wheels, the aircraft was towed to the apron at 10:10. The runway was closed for about 7 hours. The investigation found that the left landing gear down-lock cable was broken. The aircraft touched down with the wheel brakes locked due to a hydraulic lock in the system, which was the result of an incorrect manual landing gear extension procedure being used by the pilots. The pilots’ actions indicated that they did not sufficiently understand the aircraft’s landing gear system, resulting in them using inappropriate trouble shooting and rectification procedures. The pilots were not sufficiently confident of the aircraft’s fuel state to conduct a go around and fly past as cleared by ATC. With the release of the final report, the National Transportation Safety Committee’s (NTSC) issued two recommendations to address the safety deficiencies identified in the report. These covered flight crew technical knowledge of aircraft systems, fuel planning and flight management, and the regulatory oversight of the airline’s training program. 2 1.
