High reliability


Dispatch reliability was a leading design driver on the SaM146.

The regional jet market demands purpose designed engines, assuring frequent flights and quick turnaround, with no room for down time. PowerJet meets this need through a multifaceted approach.

Optimized design:

  • Simplified archiecture based on experience with the CFM56
  • Critical components and subassemblies proven by extensive testing, backed by Snecma‘s heavy investments in Research & Technology
   

 

Enhanced maintainability:

  • Easy access for quick removal/installation
  • Improved control: new FADEC (full authority digital engine control)
  • Enhanced troubleshooting: health monitoring in the flight-deck, built-in test and troubleshooting assistance


The result is significantly longer life on-wing, higher dispatch reliability and lower maintenance costs.
