## Summary

We propose to adopt a new airworthiness directive (AD) for all General Electric Company (GE) GEnx-1B engines. This proposed AD was prompted by a report of a center vent tube (CVT) failure leading to a loss of oil pressure and subsequent in-flight engine shutdown. This proposed AD would require removal of the Air/Oil Extension Ducts, part numbers (P/N) 2332M85P01 or 2331M25G03. We are proposing this AD to address the unsafe condition on these products.
