On 19 July 2018, a Quest Kodiak 100 aircraft registered P2-NTZ experienced a nose wheel collapse during landing at Mibu Airstrip, Raicoast District, Padang Province, Papua New Guinea. The Papua New Guinea Accident Investigation Commission (AIC) is conducting an investigation into this occurrence.

As part of its investigation, the AIC requested technical assistance from the ATSB. The ATSB was asked to examine the fractured nose wheel fork to determine the failure mode and if there were any pre-existing defects. To facilitate this request, the ATSB initiated an external investigation under the provisions of the Transport Safety Investigation Act 2003.

The ATSB completed the component examination and found that the assembly fractured as a result of overstress with no evidence of pre-existing defect.

The PNG Accident Investigation Commission is responsible for and will administer the release of the final investigation report into this accident. Further information regarding the occurrence can be found at www.aic.gov.pg or specific enquiries should directed to infor@aic.gov.pg.

The information contained in this web update is released in accordance with section 25 of the Transport Safety Investigation Act 2003 and is derived from the initial investigation of the occurrence. Readers are cautioned that new evidence will become available as the investigation progresses that will enhance the ATSB's understanding of the accident as outlined in this web update. As such, no analysis or findings are included in this update.
