The majority of Singapore Airlines flight crews (observed around the time of the incident) did not fully complete the required pre-flight walk-around inspections.
The ATSB is satisfied that the safety action undertaken has adequately addressed the safety issue.
In January 2024, Singapore Airlines advised the ATSB that it was initially emphasised to their A350 pilots via the publication of a memo and later to all pilots through an Internal Notice to Airmen (INTAM) on 12 December 2023, the importance of adhering to standard operating procedures in relation to the completion of exterior checks.
