GE Aviation said that it is redesigning a static compressor part of the GE9x engine designed to power Boeing’s new 777x.
According to GE chief executive David Joyce, a part near the front of the compressor is less durable than expected and may lead to repeated shop visits if not addressed.
The company found the issued in May during the block test in which exhaust gas temperature readings were outside an expected range., and now further extended tests have confirmed the issue.
GE said to install the re-engineered part in all eight engines involved in the GE9X test programme.
The issues with the Engines would further delay the first flight of Boeing 777x which was extended to early 2020.
GE9X is the largest aviation engine ever made, and specially designed for Boeing’s new 777x
