General Electric plans to ask airlines for a second round of inspections on its newest engines after an investigation pointed to different causes for failures on a Boeing 747-8 jumbo jet and on a 787 Dreamliner.
A service bulletin will be issued “in the next day or two” calling for checks on the GEnx engines’ low-pressure turbines, said Rick Kennedy, a spokesman for GE’s aviation unit. That component showed damage after a GEnx engine on a 747-8 freighter failed on takeoff in Shanghai on Sept. 11.
The China incident followed the failure of a GEnx engine on a Dreamliner during a July 28 test near Boeing’s Charleston, S.C., plant. A National Transportation Safety Board probe found a crack in a rotating shaft in that engine. The shaft wasn’t damaged on the Shanghai jet, the NTSB has said.
As GE works with U.S. regulators to identify the cause of the GEnx issues, Qatar Airways said it will defer delivery of Dreamliners it has on order until the engines are modified. Chief Executive Officer Akbar Al Baker announced the delay after a speech Tuesday in Doha, Reuters reported earlier.
