Safety action
| Action type | Proactive action |
|---|---|
| Action number | AO-2025-072-PSA-01 |
| Organisation | Regional Express Pty Ltd (Rex) |
| Action description |
Regional Express is implementing changes to the Flight crew operating manual (FCOM) workflows to address the safety issue. As this process requires careful consideration, in the interim Rex flight operations has released a notice to air crew (NOTAC 15326) and an operations notice (P27.26 RNAV Based SID Departures) to mitigate the potential hazard until the FCOM is revised. |
| ATSB response |
The ATSB acknowledges the proactive safety action taken by Regional Express and will monitor the implementation of the procedure. |
