US regulator the Federal Aviation Administration (FAA) will take no immediate action to address a smoke-related issue involving the CFM International Leap-1B engines that power the Boeing 737 Max.
The engine-maker says the successful demonstration involved a GE Aerospace CT7 turboshaft engine combined with internally-produced electric machine and power electronics.
