On 25 May 2007, an Indonesian registered Boeing 737-3YO, PK-AWP, touched down heavily while landing at Polonia Airport, Medan, Indonesia. The landing resulted in nosewheel vibration, a deflated left nosewheel tyre and overheated brakes.

The flight data recorder (FDR) was recovered from the aircraft. The Indonesian National Transportation Safety Committee (NTSC) was responsible for investigating this incident. The NTSC requested ATSB assistance in the recovery of data from the FDR tape on 12 December 2007. The Executive Director of the ATSB approved the request. To protect the information supplied by the ATSB to the NTSC and investigation work undertaken to assist this agency, the ATSB initiated an investigation under the Transport Safety Investigation Act 2003.

The FDR tape was provided to the ATSB on 17 December 2007. The tape was found to be damaged and the recovery of data was problematic, however, the ATSB successfully recovered the incident flight data from the damaged FDR tape. A data listing and graphical representation of data recorded during the incident flight and a report describing the recovery procedures, were finalised on the 10 January 2008. This information was provided to the NTSC.
