Status: Completed
Investigation completed


The ATSB has completed its technical analysis report of the cockpit voice recorder download from Boeing 747-4U3 aircraft, registration PK-GSH, on behalf of the Indonesian National Transportation Safety Committee (NTSC). The aircraft was operating a scheduled international flight between Jeddah, Saudi Arabia and Jakarta, Indonesia. When the undercarriage was extended for landing at Jakarta, the left wing landing gear failed to extend. Following a number of flypasts, the crew landed the aircraft smoothly on runway 07R. The aircraft canted to the left during the landing and an emergency evacuation was carried out.

The NTSC is responsible for investigating this occurrence. The NTSC requested assistance from the Australian Transport Safety Bureau (ATSB) in the recovery and analysis of information from the cockpit voice recorder. In accordance with clause 5.23 of Annex 13 to the Convention on International Civil Aviation, the ATSB appointed an Accredited Representative to assist the NTSC and initiated an investigation under the Transport Safety Investigation Act 2003.

The ATSB's Technical Analysis Report has been sent to the NTSC to assist its ongoing investigation. The NTSC is responsible for releasing a final investigation report regarding this occurrence.
