FAA orders seat checks on hundreds of Boeing 737 MAX jets

The Federal Aviation Administration on Tuesday issued an airworthiness directive requiring airlines to inspect seat installations on hundreds of Boeing 737 MAX aircraft after a report showed seats were not correctly mounted in their tracks, a flaw the regulator said could lead to passenger injuries.

"Improperly secured seats could shift during flight, posing a risk to passengers," the FAA said in the directive, which applies to certain 737 MAX models operated by U.S. carriers.

The agency said it acted after receiving a report detailing incorrect seat-track installation on delivered jets. The directive covers multiple airlines operating the affected aircraft, though the FAA did not disclose how many carriers or specific seat configurations were involved.

While the FAA characterized the issue as a safety concern rather than an immediate emergency, the directive adds to the regulatory scrutiny Boeing has faced over quality-control processes. Airlines must complete inspections within a specified timeframe or ground the affected aircraft, potentially disrupting schedules during the peak summer travel season.

The advisory marks the latest in a series of regulatory actions targeting Boeing's production practices. The FAA has maintained enhanced oversight of the manufacturer since a January 2024 midair panel blowout on a 737 MAX 9 operated by Alaska Airlines, which led to a temporary grounding of 171 aircraft and a subsequent cap on monthly production, according to the FAA.

The seat-track issue differs from previous quality concerns in that it involves installation work performed during final assembly rather than a supplier component defect. Seat tracks are installed by Boeing's manufacturing teams at its Renton, Washington, facility, where the company assembles all 737 variants.

The FAA's action follows a pattern of increased regulatory vigilance. Since the 2024 incident, the agency has expanded its on-site inspector presence at Boeing factories and imposed stricter documentation requirements for production approvals, according to the FAA. The Department of Justice also reached a deferred prosecution agreement with Boeing in July 2024, requiring the company to pay a $243.6 million fine and submit to independent compliance monitoring, according to court filings.

For airlines, the directive creates operational complexity during the Northern Hemisphere summer, when carriers typically run near-full schedules with load factors exceeding 85 percent. Inspections must be completed within a window specified by the FAA, and any aircraft found with improperly installed seats must be repaired before returning to service. The financial impact depends on how many aircraft require rework and how long each inspection takes, though the FAA did not provide an estimate.

Boeing did not immediately comment on the directive. The company has been working to stabilize its supply chain and improve manufacturing quality under Chief Executive Officer Kelly Ortberg, who took over in August 2024 with a mandate to overhaul the planemaker's safety culture. The company faces continued pressure from regulators, customers, and investors to demonstrate sustained quality improvements.

The 737 MAX is Boeing's best-selling jetliner, with more than 1,600 aircraft in service globally, according to Boeing. Any prolonged inspection requirement could add pressure on airlines already facing delivery delays. United Airlines and Southwest Airlines, two of the largest MAX operators, did not immediately respond to requests for comment. European rival Airbus has widened its delivery lead in the single-aisle market as Boeing's production challenges persist.

The directive also raises questions about Boeing's internal quality audits. If the seat-track issue is found to be systemic rather than isolated, it could delay the FAA's timeline for lifting the production cap, a key milestone for Boeing's financial recovery. The company has not provided a target date for when it expects the cap to be removed.

The recurring quality issues could also affect Boeing's efforts to certify new models, including the 737 MAX 7 and MAX 10 variants, which remain pending before the FAA. Each new regulatory action provides ammunition to critics who argue the company's safety culture has not sufficiently improved since the 2018 and 2019 MAX crashes that killed 346 people and led to a 20-month global grounding. Boeing's next quarterly earnings report, expected in October, will provide the first detailed update on how these regulatory headwinds are affecting its financial outlook.
