This is what I believe drove the price down.Notice how UTX sp was up. This issue will be fixed and has no financial impact to AB or BBD. All cost will be picked up by UTX to bring this part to its original life limit. Problem is most who follow bbd look at chart shape, trend, wedge, double wedge, triangle etc and try to predict where it will go. Very few look at what is actually driving the behaviour. https://www.flightglobal.com/news/articles/corrosion-cuts-life-limit-of-a220-and-e2-compressor-458694/
