Summary

The Federal Aviation Administration's Airworthiness Directive 2018-14-12 addresses all General Electric Company GEnx-1B turbofan engines equipped with specific air/oil extension ducts. This directive mandates the removal and replacement of affected extension ducts, part numbers 2332M85P01 or 2331M25G03, due to a reported center vent tube failure that caused loss of oil pressure and in-flight engine shutdown.

Why it matters
