Over a decade on the IAE V2500 and NEVER had an engine problem but I keep taxiing past NEO's that are parked. I admit I'm not an expert on the topic so I can only rely on common sense and basic observational data. I just can't get the past the idea that a jet engine that is routinely being grounded might not be a good long term investment. I'm just a simple line pilot trying to make it to 65 and I am convinced it will be easier to finish out my career in a non NEO powered jet.
