What happened
During the takeoff roll, the cockpit crew experienced a vibration within the aircraft. This was immediately followed by a loud bang and the subsequent failure of the right-hand (number 2) engine. In response to the engine failure, the captain performed a rejected takeoff, successfully bringing the airplane to a stop on the remaining runway.
The investigation
An examination of the aircraft following the incident revealed that the tire tread was missing from the number 3 tire located on the right-hand main landing gear. Investigators discovered a piece of black rubber, consistent with the missing tire tread, lodged within the fan outlet guide vanes of the engine.
Further inspection of the engine showed black smearing marks on several fan blades and bent stator vanes. The material causing the smearing and damage was identified as being similar to the tire tread material. The investigation concluded that the engine sustained substantial damage, while the airframe sustained minor damage.
