  >IndiGo still needs to replace 110 engines out of 196 that were affected, ... Essential questions not addressed: 1. What is the nature of the "fix"? 2. Have IndiGo pilots since been directed to limit power to "alt-climb"? 3. What is Pratt's analysis of failure incidence as a function of power history per engine?

    It's a geared engine, so gear failure is basically sending the engine back to the factory and rebuilding or discarding it. This is a big deal, and the reason geared engines haven't been used in aviation turbines before. If I owned an airline, I wouldn't buy one now or for 2 decades.
