Boeing faces delays in ramping up 737 MAX production amid ongoing manufacturing bottlenecks.

The FAA initially capped 737 MAX production at 38 aircraft per month after a door plug blew out shortly after a MAX flight departed Portland in 2024; production has since been increased in stages.
Ortberg said Boeing is “not stable yet at 47 a month,” underscoring that the company has not fully established a reliable production flow even at its current output rate.
Boeing’s Everett line builds the 737 MAX 8, 9 and 10, but the wings are made at the Renton facility and transported to Everett for final assembly, creating the current production bottleneck.
Once the wing-flow problems are resolved, Ortberg said Boeing’s supply chain is “in pretty good shape” to support the next production-rate increase.
Certification of the MAX 7 was completed in August, while earlier engine deicing-system problems had delayed certification of both the MAX 7 and MAX 10.
Boeing's push to increase 737 MAX production is hitting major delays, with CEO Kelly Ortberg admitting the manufacturing system needs more time to stabilize. The company is producing about 47 aircraft per month but hasn't fully mastered even that rate, Leeham News reported. BigGo Finance noted that Boeing's stock fell sharply after the disclosure, wiping out billions in market value.
The delays threaten Boeing's cash-flow targets and delivery schedules. The company aims for 52 jets monthly and expects to raise output next year, but Mezha reports that production bottlenecks are now the main roadblock to those goals.
Boeing's Renton, Washington facility makes the 737 MAX wings, which are then transported to the Everett plant for final assembly. This split production creates the current bottleneck, Leeham News explains. Ortberg said once wing-flow problems are fixed, the supply chain is "in pretty good shape" to support the next production jump.
The FAA capped 737 MAX production at 38 planes monthly after a door plug blew out on a plane departing Portland in 2024. Boeing has since increased output in stages, reaching 47 per month. But Leeham News notes that Ortberg said the company is "not stable yet at 47 a month," meaning Boeing hasn't locked in a reliable production rhythm even at its current output level.
Boeing opened the Everett North Line to handle higher 737 MAX production rates. The facility builds the 737 MAX 8, 9, and 10 variants. CEO Ortberg said certification of the MAX 10 is expected soon, clearing another hurdle before ramping up output further, IJR reported.
Boeing continues fighting quality and supply-chain issues stemming from earlier safety-related production restrictions. Engine deicing-system problems delayed certification for both the MAX 7 and MAX 10. The MAX 7 certification was finally completed in August, but these recurring setbacks have slowed Boeing's overall recovery path, Mezha notes.
