Neo is a terrible engine design. Biggest failure in aviation industry. Look for another job or be ready to company to go bankcurrpt in next 2 year. Read this link.

One of these posts say "Every new engine has teething problems, this is nothing new. Pratt isn't going anywhere" .... it's just like 1971 again....with Pan Am with the JT9 on their 747s, the engine issues were one of the many factors that ruined them in the 1970s and eventually helped put them out of business...they should have bought the extended warranty.
Neo is something like Chrysler built...not to reliable
news flash to the OP: stupid take. I can name off MANY GE and RR engines that have had issues through their first 5 years of introduction. In fact, GE was one place that frequently shrugged off the GTF platform and claimed it could never meet the performance it claimed. Surprise! GE was wrong. Again. Because they are arrogant.
Walsh and Dunn worked for them. In the engine development department. They put money ahead of testing. Awful directors.
GE Engine has teeting problems, so your guess is correct. This guy works for GE, stop screwing with minds!
The aero/performance is fine. there is just not enough cooling air to the components. The engine exceeded the performance requirement. PW should have taken that exceedence and put that back into more cooling air and the engine would have been more robust. more ground/flight testing should have been done. multiple test engines got canned as cost reduction. lots of the “teething issues” could have been avoided. not sure how designing/testing an engine in this manner is best for the shareholder when PW has spent billions fixing field issues on this engine and the 1500.
The core tech is sound, unlike the 6000 (the 6000 was missing a whole compressor stage to drive cost and weight down). There are no inherent design problems with GTF, the problem is actually at the component engineering and quality level. Now, while this is a bit surprising since they overengineered the one risk area they thought was going to be the problem (gearbox) but neglected the integration testing on the cold and hot sections, Root cause is basically a resource allocation problem in hindsight. But whether they spent extra time in development or fixing it in aftermarket they are not going to win if you remember V2500 got severely criticized for taking too long to ship. Integration of components under extreme physical stresses is a hard problem that's why there's only a handful of jet engine makers in the world.
I can say from what I have seen is OP isn't far from the truth. There is "teething problems" and then there just a failure. They are finally trying to do something about it but the damage has already been done. They have engines that cant even make full interval. The components they can modify are so screwed up at maybe 1500 hours, they can't even be modified and have to be tossed.
First of all, I feel horrible for the affected. I made the cut. So, on to this one..... maybe if I mention a code word, someone will believe I am real.... hmmmmm “bunker fix”, or how about the names Walsh or Dunn, does that ring a bell..... ok
NEO is just as bad as the 6000, don’t defend it. It is being driven to the ground by mid level management. The GTF Issues have CONTRIBUTED to this situation, as well as buying GR and Collins and all the other c-ap moves.
I still would love to know how we fly revenue engines on prototype certs.
LOL. Lets blame India’s environment for troubles with the Neo combustor. if you are selling an engine that environment, you design for it. The combustor design was woefully inadequate and it was only a matter of time before it was going to fall apart in less stringent environments.
Problem is a known Item that has been redesigned and is being replaced in the field.
New problems are always coming up with new engines, but this won't be an issue, soon.
"bankcurrpt"
ok
Thanks for the story from the guy who works at GE!
Not to mention the problem is specifically with India's environment and regulatory systems, but hey, let's just toss around gross unfounded theories like OP.
Clear way to spot the trolls on here: they always badmouth GTF. Never heard anything like it internally. Buzz off, troll.
Every new engine has teething problems. This is nothing new. Pratt isn't going anywhere.
