Renton Facility Bottleneck Delays Output Increase Plans

Boeing is facing a delay in its efforts to increase 737 MAX production due to a wing manufacturing constraint at its Renton, Washington facility. The company is working to stabilize production at 47 aircraft per month, but the transition from 42 has taken longer than expected. Boeing ultimately aims to raise output to 52 aircraft per month, with a longer-term possibility of reaching as many as 63.
