The operation of an Airbus A380 on two passenger flights with a maintenance work light in its left wing highlights the importance of ensuring tool control systems account for potential human error.
An ATSB investigation report details that the light was inadvertently left in the Qantas-operated A380 after maintenance was conducted on the aircraft’s air conditioning system at Sydney Airport on 7 January 2026.
The aircraft was subsequently flown to Dallas, and then back to Sydney, before the light was removed on 9 January.
An ATSB investigation concluded the incident was the result of a breakdown in foreign object control and tool accountability processes.
“Maintainers did not find the light during their foreign object clearance inspections at the end of the maintenance,” ATSB Chief Commissioner Angus Mitchell said.
“And the work light’s absence was not noticed when the maintainer returned the tools, or during the unreturned tool check at the end of the shift.”
A licensed aircraft maintenance engineer then issued a certificate of release to service, despite the work light being unaccounted for.
“Contributing to this, the operator’s maintenance information system did not provide a prompt or control to alert the certifier to the unreturned tool, or the unactioned unreturned tool report,” Mr Mitchell said.
In response to the occurrence, Qantas issued a safety directive to address changes to its tooling control processes and procedures.
The operator has also formed a tooling working group to work on various initiatives, including new technologies, to improve tool control across its various maintenance locations.
“Even well-established processes can be vulnerable when they rely solely on consistent human performance, particularly during maintenance tasks, which are often conducted in challenging environments and under operational pressures,” Mr Mitchell noted.
“Tool control systems and procedures must account for this variability, with safeguards to detect and recover from errors.”
