On 4 May 2021, at 1130 Wallis and Futuna Time, the pilot of a De Havilland DHC-6-300 aircraft, F-OCQZ reported a reduction in engine power on approach to Point Vele Airport, Territory of the Wallis and Futuna Islands.
The French Bureau d'Enquêtes et d'Analyses pour la sécurité de l'aviation civile (BEA) is investigating this occurrence. As part of the investigation, engine number 2 was shipped to an Australian maintenance facility for further examination, and the BEA requested appointment of an Accredited Representative from the ATSB.
To facilitate this request, the ATSB initiated an external investigation under the provisions of the Transport Safety Investigation Act 2003.
Engine examination reports were provided to the BEA by the Australian maintenance facility, at which point ATSB investigation support was completed. Should further assistance be required, the investigation will be reopened.
