A quiet revolution has taken place in the hangars and maintenance bays of America’s major airlines. The grease-stained hands ensuring your safety at 30,000 feet are increasingly located thousands of miles away, in places like El Salvador, China, and Mexico. While passengers fret about legroom and baggage fees, a far more critical component of air travel—the very nuts and bolts of the aircraft—is being handled by a globalized workforce, often with far less oversight than their U.S.-based counterparts. This shift, driven by a relentless pursuit of cost savings, has created a complex and potentially perilous global industrial maintenance complex, leaving many to wonder if we’ve outsourced safety along with the jobs.

The Ever-Expanding Global Hangar
The trend of outsourcing aircraft maintenance is not new, but its scale is staggering. What began as a trickle in the 1990s has become a flood. By 2016, 47% of major maintenance work, to the tune of $7.3 billion, was being performed by third-party vendors. Fast forward to today, and the global market for commercial aircraft maintenance, repair, and overhaul (MRO) is projected to surpass a breathtaking $81.9 billion in 2024.[1] This explosion in outsourced maintenance is, in part, a response to the post-pandemic surge in air travel, with the aviation maintenance industry seeing a 127% increase in revenue between 2020 and 2022.[2]
The FAA now certifies approximately 977 foreign repair stations in 65 countries.[3][4] While these facilities are technically held to FAA standards, the reality of enforcement is fraught with challenges. Surprise inspections, the bedrock of any robust regulatory system, are often anything but. The FAA must frequently obtain permission from foreign governments and provide advance notice of an inspector’s visit, effectively giving facilities time to present a polished facade rather than a true snapshot of their day-to-day operations.
A Patchwork of Oversight and a Prayer for Safety
For years, critics have pointed to a glaring double standard in regulations between domestic and foreign repair stations. U.S.-based mechanics are subject to stringent, unannounced drug and alcohol testing, and rigorous certification standards. In contrast, many foreign repair stations have operated without these fundamental safety checks. This regulatory gap has been a source of growing concern, with unions and safety advocates warning of the potential for a catastrophic failure.
Recent legislative and regulatory changes are attempting to stitch up these holes in the safety net. A new FAA rule, finalized in late 2023 and set to be fully implemented by 2027, will mandate drug and alcohol testing for employees at foreign repair stations who perform safety-sensitive work on U.S. aircraft.[3][4] Additionally, the 2024 FAA Reauthorization Act includes provisions for more stringent oversight, including unannounced inspections and increased data collection on maintenance errors.[5][6]
While these are steps in the right direction, the sheer scale of the global maintenance network presents a formidable challenge. The FAA has faced criticism for years from the Department of Transportation’s Inspector General for inadequate oversight of these foreign facilities.[6] The logistical hurdles of inspecting nearly 1,000 facilities spread across the globe remain a significant concern.
The Bottom Line: Costs and Consequences
The primary driver of this global shift is, of course, money. Airlines can save up to 70% on labor costs by outsourcing maintenance to countries with lower wages.[7] However, this billion-dollar savings comes with a potential cost that cannot be measured in dollars and cents. While there has not been a major U.S. airline catastrophe definitively linked to outsourced maintenance in recent years, the specter of such an event looms large. The investigation into the tragic Air India crash in June 2025 is looking closely at the airline’s maintenance regime, a stark reminder of the stakes involved.[8]
The reliance on foreign MRO services also creates strategic vulnerabilities. As one parliamentary panel in India recently noted, this dependence is a “national issue” that poses challenges to self-reliance and security. The same could be said for the United States, where the hollowing out of a skilled domestic workforce has led to a shortage of qualified mechanics.[2]
The Future of the Global Supply Chain: A Turbulent Ride Ahead

The global aircraft maintenance supply chain is at a critical juncture. The trend of outsourcing is deeply entrenched, and the economic pressures on airlines are unlikely to relent. The recent push for greater regulatory oversight is a positive development, but it remains to be seen how effective these new measures will be in practice.
The potential for a major incident remains a chilling possibility. The intricate web of global maintenance means that a single faulty repair, a misread manual, or an improperly trained mechanic could have devastating consequences. As the industry moves forward, it must grapple with a fundamental question: In the relentless pursuit of profit, have we gambled with the safety of the flying public? The answer may only become clear in the aftermath of a tragedy that could, and should, have been prevented.
