Boeing announced Monday that it has completed its $4.7 billion acquisition of Spirit AeroSystems, the Wichita-based manufacturer responsible for producing major structures for several Boeing jetliners, including the 737 Max series. The move marks one of the most significant strategic reversals in the aerospace giant’s modern history, bringing its largest external supplier back under Boeing’s direct control nearly two decades after it was spun off.

CEO Kelly Ortberg described the moment as a turning point in Boeing’s effort to stabilize its production lines and restore confidence after years of manufacturing setbacks and safety controversies. “As we welcome our new teammates and bring our two companies together, our focus is on maintaining stability so we can continue delivering high quality airplanes, differentiated services, and advanced defense capabilities for our customers and the industry,” Ortberg said in a statement.

Spirit AeroSystems, once an integral part of Boeing before the 2005 divestiture, became a central focus of scrutiny as repeated quality lapses disrupted the production of Boeing’s most in-demand aircraft, particularly the 737 Max and 787 Dreamliner. Bringing Spirit back in-house signals Boeing’s acknowledgment that its long-running strategy of outsourcing large portions of aircraft manufacturing has created vulnerabilities that became increasingly visible in recent years.

The reintegration effort accelerated in July 2024, when Boeing announced plans to reacquire the supplier as pressure mounted following a highly publicized safety incident earlier that year. In January, an Alaska Airlines 737 Max 9 experienced a mid-flight blowout of a door-panel plug at roughly 16,000 feet over Oregon. While the incident fortunately caused no serious injuries, it left a large opening in the fuselage and reignited global concerns about Boeing’s quality controls.

Investigators from the National Transportation Safety Board later revealed that four critical bolts meant to secure the door panel were missing after repair work performed at a Boeing facility—a discovery that reignited questions about oversight, training, and procedural rigor within the company.

The Alaska Airlines incident arrived on top of Boeing’s ongoing struggles related to two catastrophic crashes involving the 737 Max in 2018 and 2019, which claimed 346 lives and led to the worldwide grounding of the aircraft for nearly two years. The crashes triggered a series of investigations and a criminal case against the company, with the Justice Department accusing Boeing of misleading regulators about a flight-control system tied to both tragedies.

That criminal case concluded only weeks ago when a federal judge approved a Justice Department agreement to dismiss the charge. Under the terms of the deal, Boeing committed to more than $1.1 billion in fines, compensation, and internal safety improvements. The company has portrayed its acquisition of Spirit as part of a broader effort to rebuild trust and tighten oversight across its manufacturing chain.

Though the purchase price was widely reported as $4.7 billion, Boeing has said the total value of the acquisition is closer to $8.3 billion once debt assumptions are included. Investors reacted positively to the completed deal, with Boeing shares rising about 2% during midday trading Monday.

For Boeing, reabsorbing Spirit represents more than a corporate realignment. It is a test of whether the company can regain the discipline, consistency, and transparency needed to reassure regulators, airlines, passengers, and employees that its troubled era of safety lapses is finally waning. Much of that challenge now rests on how effectively Boeing can reintegrate a supplier whose performance has played a central role in some of the most consequential setbacks in the company’s history.
