The Air Accident Investigation Bureau (AAIB) of Mongolia is investigating a runway excursion that occurred at Oyut Domestic Airport, Mongolia on 30 March 2012 and involved a Fokker 50 aircraft, operating as Aero Mongolia Airlines flight Ju 8257. The aircraft exited to the right of the runway and its nosewheel and propeller struck a frangible, stake-mounted runway edge light as the pilot manoeuvred the aircraft back onto the runway. The aircraft was substantially damaged and there were no injuries to passengers or crew.
The investigation is being carried out in accordance Mongolia's obligations as the State of Occurrence under Annex 13 to the Convention on International Civil Aviation. On 11 May 2012, the AAIB requested Australian Transport Safety Bureau (ATSB) assistance by providing investigator support to obtain relevant technical information and verify the correct lighting installation. In accordance with paragraph 5.23 of Annex 13, the ATSB appointed an Accredited Representative to assist the AAIB. To facilitate this support, the ATSB commenced an investigation under the Transport Safety Investigation Act 2003. The ATSB coordinated with the Australian aerodrome lighting manufacturer for technical information and diagrams, which were provided to the AAIB.
