Boeing B-777 incident near Houston, Texas, August 11, 2004
On August 11, 2004 at about 9:55 pm local time, a Boeing B-777, registered GVIID, suffered minor damage in an incident near Houston, Texas (Houston Intercontinental airport). It was flown under foreign airline rules (Part 129). No one was hurt; 129 people were on board or involved. The weather was visual conditions (good weather).
The NTSB's probable cause their words, unchanged
the failure of a high pressure turbine blade which damaged an oil seal and allowed smoke to enter the cabin. Contributing to the blade failure was the mis-labeling of the blade's part number by the manufacturer, which allowed the blade to remain in service far in excess of it's life limit.

The NTSB's narrative final · quoted from the NTSB record
As the throttles were advanced for takeoff, the flightcrew heard a noise and felt a vibration from the left side of the airplane. As the airplane rotated, the crew received a cockpit warning of LH Eng Vibration - Level 5. During the climb, the crew observed smoke and haze in the cockpit and the cabin crew advised that the cabin was filling with smoke. The flightcrew declared an emergency and made an immediate landing and emergency evacuation. The investigation revealed that a turbine blade in the left engine had failed due to a fatigue crack and the resulting damage caused excessive vibration in the engine. As the engine continued to vibrate, an oil seal failed allowing oil to contaminate the bleed air and create smoke in the cockpit and cabin. The failed blade had been mis-marked with the wrong part number by the manufacturer, which allowed it to remain in service far in excess of it's life limit until the fatigue crack developed.
