Boeing has suspended all test flights for its 737 Max single-aisle jets after the manufacturer of new engines on the aircraft discovered a safety problem.
The issue involves a potential manufacturing quality problem with low-pressure turbine discs in the CFM LEAP 1B engine, Boeing said.
The first 737 Max-9, with fuel-saving blended winglets, took to the skies on its first-ever flight a during a morning journey from Boeing’s huge Renton complex.
CFM, a joint venture between General Electric Aviation and French aerospace company Safran, is making the new engine model for what is already Boeing’s fastest-selling aircraft.
Chicago-based Boeing (NYSE: BA) said its flights have not had any engine problems, but that it halted the flights “out of an abundance of caution” and is working with engine maker CFM to determine the root of the problem.
“The step is consistent with our priority focus on safety for all who use and fly our products,” Boeing said.
Boeing said it still plans to begin 737 Max deliveries this month. All Boeing 737 aircraft are made at Boeing Commercial Airplanes’ sprawling Renton complex. Production of the Max aircraft and the older Next Generation 737 aircraft will continue.
