Reducing aircraft downtime during maintenance visits thanks to Critical Chain Project Management



The Embraer maintenance facility at Le Bourget airport is keen to drastically reduce the aircrafts downtime, particularly during Type C maintenance, and to perpetuate this performance.


  • Critical Chain implementation for dynamic scheduling of the mechanics' work throughout the maintenance visits.

  • Reduction of multitasking when launching work cards.

  • Implementation of aircrafts "pipelining".

  • Development of a Portfolio Fever Chart for the hangar.

Results obtained

  • Turn-Around-Times divided by 2 for all aircrafts. Example: Check C maintenance in 5 weeks instead of 10 weeks.

  • Increase in the mechanics productivity by more than 30%.

  • Improved visibility, reduced stress and better setting of priorities by the management.

I want the same results
