In March 2019, the ATSB issued a safety advisory notice advising all maintenance staff working on Robinson helicopters to ensure that before re-using a self-locking nut, the correct part number is fitted, and that the D210-series corrosion-resistant nuts are used for reassembly of critical fasteners in accordance with the Robinson Helicopter Company instructions for continued airworthiness.Īustralian Aviation has approached Cloncurry Air Maintenance for comment.Ĭloncurry mayor Greg Campbell paid tribute to Acton shortly after his death. The ATSB said Cloncurry Air Maintenance has since improved its practices, which has included progressive certification for tasks, adopting the helicopter manufacturer’s checklists for their inspections, removing all untracked MS-series self-locking nuts from stores, and completing inspections of the flight controls on all the Cloncurry Mustering Company helicopters with nil defects reported. “Audits may also be used to identify potential underlying human factors issues, which may be raised as an observation or opportunity for improvement to inform the auditee of best industry practices.” This accident reinforces the importance of auditors inspecting the evidence collected during an audit to ascertain whether the requirements are being met, specifically conformance with the relevant standards,” Dr Godley said. “Audits are essential for independently verifying the effectiveness of an organisation’s processes and procedures. The investigation also found the maintenance organisation had limited internal independent oversight and increased reliance on audits for the evaluation of its quality performance. In addition, in the years leading up to the accident, staff changes reduced the maintenance provider’s levels of qualifications and experience. Voice-activated intercom eliminates the need to use intercom switches during doors-on flights.The investigation noted that in the weeks prior to the accident the maintenance company was experiencing a period of very high workload that likely exceeded the workforce’s capability and reduced the chief engineer’s capacity to oversight maintenance activities.
