CFM LEAP Engine Flies

FLIGHT TESTS have started on CFM International’s LEAP-1B engine

FLIGHT TESTS have started on CFM International’s LEAP-1B engine using a General Electric modified Boeing 747 flying test-bed, N747GE (c/n 19651). The initial flight took place on April 29 from Victorville, California, and was the latest milestone in a two-year development programme culminating in engine certification in 2016.

The first customer deliveries of Boeing 737 MAX are scheduled for in 2017. According to a company statement, the engine performed well and completed multiple aeromechanical tests at various altitudes during the 5hrs 30mins flight.

The LEAP-1B engine is the exclusive powerplant for the 737 MAX family, with CFM being the only engine provider for the 737 family since the first Classic entered service in 1984.
Steven Crane, CFM’s chief test pilot, said: “I continue to be really impressed with LEAP family. These engines are demonstrating a maturity that you don’t always see in new products. I think our airline customers are going to be very pleased with this engine.”

There are now 26 LEAP engines (all three models) on test, with ten additional engines in various stages of final assembly.
