AVIATION BUSINESS SOLUTIONS CASE STUDY

Streamlining operations to reduce turnaround time (TAT) for 737NG landing gear overhauls

The challenge

A prominent South American carrier looked to Aviation Business Solutions to address inefficiencies and expedite turnaround times in their existing Boeing Next-Generation 737 landing gear overhaul process. Struggling with exceeding turnaround times (TAT) of 120+ days on landing gear overhauls, the airline faced the prospect of missing its own target of 90-120 days TAT. 

This shortfall not only jeopardized their operational efficiency but also raised the specter of expensive outsourcing of landing gear overhauls to meet demand. In addition, the airline hoped to become an approved Boeing Landing Gear Repair and Overhaul supplier. 

Our approach

This carrier partnered with our Maintenance and Engineering practice to resolve these challenges, as well as ensure they had the following in place to be successful: 

  • Incorporation of industry best practices and efficient processes 
  • Clear recommendations and actionable roadmaps to surpass their turnaround targets

With expertise in airline maintenance and engineering processes, MRO best practices, and strategic consulting, our team focused on tackling the airline's challenge to optimize their landing gear overhaul processes and provide operational efficiency by: 

  • Performing an off-site review of their processes, schedule, manpower, tracking procedures, capabilities, and back-shop tooling.
  • Eliminating and optimizing workflows
  • Identifying and minimizing part transits to multiple shops
  • Recommending how to track parts throughout the program
  • Analyzing each work stop to identify waste and provide recommendations
     

"I'm thrilled to share some positive news with you. We've successfully reduced the TAT for this shipset to just 53 days, this achievement has enabled us to process an additional shipset this year."
