Flybe DH8D near BIrmingham on Jul 22nd 2019, cabin pressure problems
Last Update: April 9, 2020 / 20:48:31 GMT/Zulu time
The aircraft remained on the ground for about 12 hours then returned to service.
The UK AAIB released their bulletin stating: "Soon after being notified of the event the AAIB released the aircraft for maintenance action and entry back into service. The operator assumed this included the CVR and FDR. The CVR was subsequently overwritten after the aircraft returned to service and thus not analysed."
The AAIB continued: "During the engineering investigation no faults were indicated on the cabin pressure control panel. Also, there were no messages on the central diagnostic system when the aircraft was pressurised in automatic and manual modes to the maximum permitted differential pressure. The aircraft was returned to service the same day when it flew from Birmingham to Edinburgh without event."
However, this was only the first of 9 similiar events until the aircraft was removed from service for 11 days for a thorough engineering investigation. The AAIB reported: "After the ninth event, involving another emergency descent, the operator withdrew the aircraft from service and conducted an in-depth investigation into the recurring fault. Several bleed air and pressurisation components were replaced before the aircraft returned to service. The absence of further reported pressurisation faults since the aircraft returned to service indicates that this intervention was successful. It is therefore possible that several events, including the second emergency descent, would have been avoided if this intervention had occurred sooner."
