The maiden flight of Boeing 777x will be further delayed from the targeted date of 26 June, due to snags in GE9x engines.
Boeing CFO, Smith, said “some challenges they are working through there on testing. So, we are having to do some re-testing…”
Boeing fired up the first shipset of GE9X engines installed on its first 777-9 test-aircraft, WH001 on May 29. However, the results were not satisfactory and GE Aviation confirmed the issues,
GE9X General Manager Ted Ingling told Aviation Week, “During a factory test an engine gave us a signal about its health,” and “We had an ‘anomaly’ in the compressor and we halted the run.”
The GE9X is set to be the biggest jet engine ever produced in the history of Aviation. It’s full 11 feet in diameter is larger than the fuselage of a Boeing 737.
Emirates, is the largest customer with 150 Boeing 777X jets on order and was expecting their first aircraft of the type in June 2020. But now the delivery date could slip into 2021.
