A VARA Virgin Australia Regional Airlines Fokker 100, registration VH-FNJ performing flight VA-721 from Adelaide,SA to Perth,WA (Australia), was enroute at FL320 about 120nm east of Perth when the crew initiated an emergency descent due to the loss of cabin pressure. During the descent smoke was observed in the cabin. The aircraft levelled off at 9000 feet and continued for a safe landing in Perth about 24 minutes after leaving FL320.
On Jun 15th 2020 the Dutch Onderzoeksraad/Dutch Safety Board (DSB) reported a technical investigation revealed a faulty cabin pressure regulator unit. The ATSB reasoned the cause was identified, no operational disruptions occurred and there were no further lessons to be learned from this occurrence and thus did not undertake any investigation.
