I still don't understand how these problem were not discovered during the testing period I agree and on the other hand it looks that Lufthansa have not so many problems with the engines. The delivered Lufthansa A320neos are well in use, if we look to the daily flights (flightradar24). It looks like that the probelm has also to do with the flight pattern. |

It was said it has a lot to do with the humidity.... |

Length of flights was a thing as well, LH 1-1.5 hours against Go 2-3 hours ? |

All trend of flights should have been tested too, short, medium and long in my opinion. |

The most striking fact, in my opinion, is that P&W customers stick to their engine choice. Lack of availability of rival LEAP 1-A engines is one reason, but customers also obviously believe that the GTF problems will soon be forgotten. The only possible exception is QR, which has been talking of changing its order, but does not seem to have acted accordingly.
Airbus must be losing some sales, since the slower-than-planned -neo production ramp-up means lack of availability, but I don't see the problems as major.

I still don't understand how these problem were not discovered during the testing period Tests don't unveil all problems, because they cannot reproduce all the conditions that are going to be met in airline operations. Usually, however, unexpected problems emerge after years - not weeks - of operation. I suppose the pressure for a short time to market has led to some corner cutting. That was unwise, but hindsight is always wonderful. |

I am also believe that due to current low & stable fuel price the damage incurred by engine shortage is still controllable as some customers have agreed to buy ceo for short term delivery. (Delta, Spirit, Cebu, AirAsia). The CFM LEAP should be totally sold out at least till 2019? Hopefully P&W could sort all issues out once & for all. They promised to sort the engine cooling in 2016, only to found combustion chamber degradation & carbon seal problem, one of the latter supposed to sort out by Apr 2017 but it didn't. (If I didn't get it wrong, there is no similar issue heard for PW1500G for CSeries?) |
