The Boeing 777-232ER aircraft, Delta Airlines flight 55, was scheduled to take-off from Hartsfield-Jackson Atlanta International Airport (ATL), Atlanta, Georgia to Narita International Airport, Tokyo, Japan. While performing a take-off roll the aircraft encountered a failure on the no.2 engine. Prior to the failure, pilots reported of experiencing the aircraft shudder and noticed the no.2 engine’s exhaust gas temperature (EGT) had reached the limit. The pilot immediately aborted the take-off, taxied the aircraft off the runway and shutdown the no.2 engine. Except for the no.2 engine, there was no damage to the other parts of the aircraft and no one on-board the aircraft was injured due to the

Till date it is the largest twinjet aircraft with a seating capacity of 314 to 451 passengers and a range of 5235 to 9380 nautical miles (Boeing, n.d.). The distinct feature about this aircraft is that it has the largest high bypass turbo-fan engine, six wheels on each landing gear, a circular fuselage cross-section and a blade-shaped tail cone. This is the first fly-by-wire airliner developed by Boeing, moving away from the conventional manual flight controls to electronic interface units where computers can make the decision on the flight control movement.

The aircraft is fitted with two RB211-Trent 895-17 high bypass turbofan engines manufactured by Rolls-Royce plc. The engine is capable of producing thrust from 75,000lb up to 95,000lb (Trent 800, n.d.). It is made of a three-shaft, axial flow and fully-ducted turbofan architecture. The engine features a single-stage fan of 110inches that is driven by a five-stage low pressure turbine, an eight-stage intermediate pressure compressor driven by a single-stage intermediate pressure turbine, a six-stage high pressure compressor driven by a single-stage high pressure turbine and a single annular combustor consisting of 24 fuel injectors (Trent 800, n.d.). The engine is known to be low weight, low oil consumption, low idle thrust to reduce
