Boeing suspends 737 MAX flights, cites ‘potential’ CFM LEAP-1B issue

Boeing has suspended 737 MAX flights after being informed by CFM International of a potential issue with the aircraft’s LEAP-1B engine, although Boeing says MAX 8 deliveries will begin this month as planned. “CFM has notified us of a potential manufacturing quality escape with low pressure turbine (LPT) discs in LEAP-1B engines delivered to Boeing,” Boeing said. “We are working with CFM to inspect the discs in question. CFM and its supplier notified us after discovering the issue as a part of their quality inspection process. At no time have we experienced an issue associated with the LPT during our ongoing MAX testing program.” Boeing said the decision to suspend MAX flights was made “out of an abundance of caution.” The suspension comes just as Boeing was preparing to begin delivery of the 737 MAX 8/ <br/>
