US orders 'urgent' repairs to Boeing 787 engines

 

US officials have ordered Boeing (NYSE: BA - news) to make "urgent" repairs to General Electric (Euronext: GNE.NX - news) engines on as many as 150 787 Dreamliner airplanes to avoid sudden failure in icy conditions.

The directive follows a recent incident that caused an engine on a 787, Boeing's newest passenger plane, to shut down mid-flight.

The Federal Aviation Administration said Friday it was ordering modifications that would prevent ice from accumulating on fan blades in GE's most advanced engines, causing them to rub against the engine casing, which can cause "damage and a possible in-flight non-restartable power loss of one or both engines."

The Dreamliner is constructed largely of advanced lightweight carbon-fiber reinforced composite materials that reduce fuel use.

However, the aircraft has been hit by a series of problems during development and production as well as since its first commercial flight in late 2011.
