New problem found on Boeing 737 Max planes New YorkCNN —  A new problem has been found during the production of 737 Max jets that will force Boeing to rework about 50 planes that have not yet been delivered. The problem was disclosed in a memo sent to Boeing (BA) employees Sunday by Stan Deal, the head of the company’s commercial aircraft unit. An employee at Boeing supplier Spirit AeroSystems, which makes the fuselages of the 737 Max jets, notified the plane maker that two holes may not have been drilled exactly to Boeing’s requirements, according to Deal’s memo.
