Qantas A380 Operated 294 Hours with Tool in Engine: ATSB
Qantas A380 Incident: ATSB Report Reveals Maintenance Oversight
The recent report by the Australian Transport Safety Board (ATSB) has unveiled a concerning incident involving a Qantas Airbus A380, which operated for almost 300 hours with a maintenance tool lodged in one of its engines. This incident raises significant safety concerns, prompting the ATSB to recommend crucial changes to Qantas’ maintenance protocols to prevent similar occurrences in the future.
On December 6, 2023, Qantas’ Airbus A380-842, registered VH-OQI, completed a routine flight from Sydney (SYD) to Los Angeles International Airport (LAX). After its arrival, engineers conducted a standard turnaround maintenance check. However, the aircraft went on to fly 34 sectors over 294 hours before a scheduled maintenance check revealed a 1.25-meter-long nylon tool stuck in one of its four Rolls-Royce engines.
Key Findings from the ATSB Report
During the maintenance check on January 1, 2024, engineers discovered the tool wedged against the low-pressure outlet guide vanes of the engine. This component is essential for the proper functioning of jet turbine engines. The tool, designed for turning engine compressors during inspections, had been inadvertently left inside the engine during the previous maintenance check.
The ATSB’s investigation revealed that the tool had gone unnoticed for nearly a month, despite multiple flights and a shorter maintenance check performed in December 2023. Notably, it was not detected during pre-flight inspections prior to the aircraft’s 34 flights.
What the ATSB Concluded
According to ATSB Chief Commissioner Angus Mitchell, the oversight stemmed from maintenance engineers failing to identify the tool during checks for foreign objects after the borescope inspection. “The certifying engineer released the aircraft for service with the tool unaccounted for,” Mitchell stated.
The tool’s extended presence in the engine caused it to become deformed due to high-energy airflow, but fortunately, no damage was reported to the engine components.
Recommendations for Qantas
The ATSB emphasized the crucial need for stringent maintenance protocols to prevent foreign object damage. The report stressed that “correctly applying tool control is fundamental to mitigating against any human errors that may arise.”
In response to the findings, Qantas Engineering management has briefed all staff on the importance of returning tools and adhering to tool control measures. The airline has also initiated an internal investigation that has led to the implementation of a new safety directive focused on compliance with tool management requirements.
Qantas’ Commitment to Safety
In a statement addressing the ATSB report, a Qantas spokesperson confirmed that the flexible plastic tool did not impact the engine’s operation and emphasized the airline’s commitment to safety. “We take this extremely seriously. While there was no damage sustained to the engine, it is critical that the correct lost tool processes are followed,” the spokesperson said.
Conclusion
The Qantas Airbus A380 incident serves as a stark reminder of the importance of rigorous maintenance practices in aviation. With the ATSB’s recommendations, Qantas aims to enhance its procedures to ensure such oversights do not occur in the future.
