The ATSB has commenced a transport safety investigation into an occurrence involving a De Havilland Canada DHC-8-102, registration VH-QQD, 83 km north-west of Perth Airport, Western Australia, on 20 November 2021.
On 20 November 2021, VH-QQD was conducting a scheduled flight from Perth to Port Hedland. During climb, as the aircraft approached 10,000 ft, the crew identified that the cabin had not pressurised. The flight returned to Perth.
It was later identified that the aircraft had been undergoing maintenance, and for operational reasons the cabin recirculation fan had been removed and fitted to another aircraft. The aircraft had not been removed from the schedule, and its unserviceability was not detected prior to flight.
The evidence collection phase of the investigation will include interviewing involved personnel, and examination of maintenance records and other relevant evidence. A report will be published at the conclusion of the investigation.
Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant parties, so that appropriate safety action can be taken.
