51: 323: 42: 450: 550:(IFSDs). Investigation revealed that the failures were caused by TGB radial gear cracking and separation. This through the combined effect of manufacturing process and operating stresses. Further inspections found two additional radial gears with cracks. This condition, if not corrected, could result in additional IFSDs of one or more engines, loss of thrust control, and damage to the airplane. The Airworthiness Directive requires compliance by taking remedial measures within five days of receipt of the AD. All affected modules have been replaced. 2529: 382: 582: 442: 474:, at 127,900 lbf (569 kN), the engine held the record for the highest thrust achieved by an aircraft engine (the maximum thrust for the engine in service is its rated thrust 115,300 lbf (513 kN)). This thrust record was reached inadvertently as part of a one-hour, triple-red-line engine stress test using a GE90-115B development engine at GE's outdoor test complex near 564: 230:. One of the major innovations for the engine were its carbon fiber composite fan blades, which were both lighter and stronger than traditional materials. However, the UDF was less reliable than the turbofans of the era, lower fuel costs made the cost of developing the engine less attractive, and the company was worried the GE36 would cannibalize sales of the highly successful 918:, and the LM9000 with water augmentation outputting 75 MW (101,000 hp) at a 42.7% efficiency before cogeneration. The engine's 33:1 pressure ratio comes from a 4-stage low pressure compressor followed by a 9 stage high pressure compressor, driven by a 2 stage high pressure turbine and a 1-stage low pressure turbine, powering a 4-stage free turbine. 410:, the GE90 series held the title of the largest engines in aviation history. The fan diameter of the original series being 123 in (310 cm), and the largest variant GE90-115B has a fan diameter of 128 in (330 cm). As a result, the GE90 engine can only be air-freighted using an outsize cargo aircraft such as the 518:

Findings were a stage 2 turbine blade had separated at its shank damaging the trailing blades causing the vibration. The debris was contained in the engine casing.

The initial GE90 fan shaft design loads were greatly increased for operational torque and the fan blade-off condition. To accommodate the increase in fan-shaft torsional and bending stresses, a steel alloy, GE1014, not previously used in aircraft engines was required. A significantly longer fan shaft

The GE90's 10-stage high-pressure compressor developed a then-industry record pressure ratio of 23:1 and is driven by a 2-stage, air-cooled, HP turbine. A 3-stage low-pressure compressor, situated directly behind the fan, supercharges the core. The fan/LPC is driven by a 6-stage low-pressure turbine.

On August 11, 2004, a GE90-85B powering a Boeing 777-200ER on British Airways flight 2024 suffered an engine failure on takeoff from George Bush Intercontinental Airport, Houston. The pilots noticed a noise and vibration on takeoff but continued the rotation. At 1500 ft AGL they noticed smoke

The FAA issued an Airworthiness Directive (AD) on May 16, 2013, and sent it to owners and operators of General Electric GE90-110B1 and GE90-115B turbofan engines. This emergency AD was prompted by reports of two failures of transfer gearbox assemblies (TGBs) which resulted in in-flight shutdowns

On November 10, 2005, the GE90 entered the Guinness World Records for a second time. The GE90-110B1 powered a 777-200LR during the world's longest flight by a commercial airliner, though there were no fare-paying passengers on the flight, only journalists and invited guests. The 777-200LR flew

In the late 1990s, Boeing began developing ultra-long-range variants of the 777, the 777-200LR and 777-300ER. For these aircraft a more powerful engine in the thrust class of 100,000 lbf (440 kN) was required, leading to talks between Boeing and engine manufacturers. General Electric

The higher thrust GE90-110B1 and -115B engines, in combination with the second-generation 777 variants -200LR and -300ER, were primary reasons for 777 sales being greater than those of the rival A330/340 series. Using two engines produces a typical
