In November 2011, Boeing said it would use the diameter engine. The landing gear will need to be made longer by 6–8 inches (15–20 cm). This is to make sure the engines stay above the ground. Boeing will probably say exactly what the 737 MAX looks like sometime in 2013. On May 17, 2012, Boeing said the engine's diameter had been made bigger. This means it is now 69.4 inches (176 cm).
