A performance improvement case study in aircraft maintenance and its implications for hazard identification

Area of Science:

• Aviation Engineering
• Industrial Engineering
• Safety Science

Background:

• Aircraft maintenance is a safety-critical, complex, and competitive industry.
• Existing processes require innovative solutions for efficiency without compromising safety.
• A need exists for ecologically valid models of operational systems in aircraft maintenance.

Purpose of the Study:

• To develop a comprehensive and ecologically valid model of the aircraft maintenance operational system.
• To introduce a performance reporting system (Blocker Report) to identify operational impediments.
• To design a Blocker Resolution Process to address identified issues and improve system performance.

Main Methods:

• Development of an ecologically valid model representing actual operational activities.
• Creation of the Blocker Report to capture data on factors hindering task or check performance.
• Implementation of a Blocker Resolution Process to systematically address identified issues.

Main Results:

• Significant improvements in performance were achieved for the company during the initial trial.
• The Blocker Report and Resolution Process effectively identified and addressed performance impediments.
• The developed model provided a framework for system improvement.

Conclusions:

• A comprehensive, ecologically valid model is crucial for improving complex systems like aircraft maintenance.
• The Blocker Report and Resolution Process offer a practical approach to enhancing safety and efficiency.
• Findings have implications for safety management systems and hazard identification in aviation.
