Key Takeaway
Aerospace manufacturing in Mexico has entered a new phase: a decade of aircraft demand is sold out, and the constraint on output is certified people, not orders or machines. This guide maps which aerospace work belongs in which kind of Mexican location, and where new capacity can still be built and staffed.
For a decade, every conversation about aerospace manufacturing in Mexico started with cost. The industry’s problem has changed. Airbus and Boeing hold a combined backlog of roughly 16,000 aircraft, close to ten years of production at current rates. Nobody in commercial aerospace is short of demand.
What the industry is short of is the ability to build what it has already sold. The analysts who cover the supply chain most closely have spent two years saying the same thing: output is now set by the supply side, the recurring choke points are castings, forgings, and engine hardware, and the deepest constraint underneath all of them is people. Aviation Week’s supply-chain coverage has documented that shift in detail.
That reframes the location question. The old question was where aerospace work could be done cheaply. The 2026 question is where new capacity can be built, staffed with certified people, and kept staffed for a decade. Mexico is one of the few credible answers, for reasons more specific than the usual cluster map.
A Sold-Out Decade
The demand side of aerospace is settled through the 2030s. The two major airframers delivered just under 1,400 aircraft in 2025 while their combined backlog held near 16,000. Narrowbody rates are climbing again: the 737 line was cleared in May to build at 47 per month with targets beyond that, and the A320 family passed 50 per month with a published path to 75 in 2027.
The engine side is running even hotter, and it concentrates demand on exactly the hardware that is hardest to make. LEAP engine shop visits are forecast to grow from roughly 700 a year today to more than 5,000 a year by 2040, geared-turbofan inspections had more than 600 aircraft on the ground this spring waiting for shop capacity, and the largest castings suppliers are reporting record spares growth. Every one of those engines and repairs flows through cast parts, machining, welding, and layer upon layer of certified inspection.
For a supplier, this is the best demand environment in a generation. It is also a trap: accepting rate increases without a credible plan for the people to execute them converts a record backlog into a record penalty exposure.
The Real Bottleneck Is Certified People
Aerospace capacity is measured in machines and delivered by people. A five-axis mill without a qualified machinist is inventory. A penetrant line without certified inspectors is a room. The industry’s workforce math in the United States makes this the binding constraint for the ramp: attrition in aerospace and defense runs near 15 percent, roughly double the all-industry average, while about 29 percent of the workforce is over 55, according to Deloitte’s industry outlook. Fifty-six percent of companies report they cannot hire the skilled manufacturing labor they need, with machinists, welders, and NDT inspectors the most acute gaps.
What makes aerospace different from general manufacturing is how slowly that labor converts into usable capacity. A nondestructive-testing inspector needs months of supervised hours before reaching certification. Weld repair on rotating hardware demands qualified stamps. Quality audits assume the same trained people will be there next year. When a certified inspector leaves, the operation loses more capacity than a machine failure would cost it, and the replacement clock starts at zero.
This is why the location decision has quietly become a retention decision. The regions that built aerospace over the last forty years concentrate certified talent, and they concentrate the competition for it in the same square miles. In a ramp, that competition prices itself into wages, turnover, and training money walking out the door mid-qualification.
Where Mexico Fits Now
The question that follows is where certified people can still be found and kept. Aerospace manufacturing in Mexico is no longer an experiment, and it long ago outgrew assembly work. The industry federation counts 386 aerospace companies across 19 states, employing about 50,000 people directly, with exports above $10 billion and a sector plan that projects roughly doubling in size by the end of the decade. The country is the sixth-largest supplier of aerospace parts to the United States, and the recent investment record includes engine MRO capacity, engineered components, and precision machining from European and North American suppliers alike. The roster of aerospace companies in Mexico runs through Querétaro, Chihuahua, Baja California, and Sonora, and it now includes Sinaloa.
The full picture includes the trade environment. The 2026 rules treat metal-bearing goods from Mexico less generously than aerospace goods from Europe, the UK, Japan, or Korea, and the rules have been revised and litigated repeatedly this year. Three facts keep the picture in proportion. Coverage is tariff-line specific, and many low-metal aerospace articles, including most composite and interior work, fall outside the covered lines or under a weight-based de minimis. Parts classified under the aircraft heading generally qualify under USMCA rules of origin through a straightforward tariff-shift rule, and qualifying goods have been exempt from the blanket border surcharge under the rules in force as of this writing.
For covered metal articles, exposure becomes a documentation discipline: metal-origin certificates, weight substantiation, and in defined cases manufacturing drawback. None of that is a promise, and any specific product deserves a review with trade counsel. It is, however, manageable compliance work of the kind mature importers do every day, and it rewards operations with professional customs machinery behind them.
Set against that: the workforce math does not change with a proclamation. A trained inspection bench compounds in value for a decade under any tariff schedule. That is why the durable way to think about Mexico in 2026 is not a bet on trade policy in either direction. It is a decision about where people for the ramp can actually be found, trained, and kept.
The Parts Decide the Place
Aerospace is not one industry; it is a dozen part families with different location logic. The table below is how we walk suppliers and OEM supply-chain teams through the decision, built from decades of operating aerospace clients across our campuses. No single city wins every row, ours included.
| Part Family | What Decides the Location | Where the Math Points |
|---|---|---|
| Engine components, castings finishing, NDT | Retention. Long certification curves make turnover the dominant cost. | Labor markets with a technical pipeline and few competing employers |
| Composites and interiors | Labor intensity and trainability; typically low metal content simplifies trade exposure. | Same profile: trainable, stable workforce |
| Precision machining, detailed parts | Machinist availability and poaching exposure in saturated corridors. | Markets where you set wage norms rather than inherit them |
| Electro-mechanical assembly | Recruiting at scale; note copper-content trade rules for wire-heavy products. | Campus markets with mass-recruiting infrastructure |
| Large aerostructures | Logistics of size and metal-heavy trade exposure dominate. | Sites adjacent to final assembly lines, with heavy-gauge logistics |
| Software-intensive systems and avionics | Depth of the engineering pool outweighs everything else. | Established engineering metros, not manufacturing labor markets |
Read the first three rows together and a pattern appears. The part families driving the ramp, engine hardware above all, are the ones where certified people take longest to build and cost most to lose. For that work, a mature cluster’s advantages fade against its turnover, and a younger labor market with a real technical pipeline starts to win the ten-year math. That inversion is the single most useful thing a site-selection team can take from Mexico’s aerospace story right now.
The Mazatlán Case
This is the reasoning an aerospace manufacturer tested in Mazatlán, and the early evidence is unusually clean. Consolidated Precision Products, a global producer of mission-critical castings, expanded into Tetakawi’s Mazatlán Manufacturing Campus, our Manufacturing Community within the city’s 100-acre industrial park, to add finishing and inspection capacity: penetrant and radiographic inspection, ultrasonic testing, weld repair, grinding, on castings up to six feet. It is precisely the training-intensive, certification-heavy work in the table’s first row.
The staffing model is the part worth studying. CPP hired locally, sent its first cohorts to established plants for qualification, and brought them home to run the lines. The Mazatlán site now leads CPP’s global network in employee retention, and the first generation of hires has become the training bench for the next.
“We brought those people back to Mazatlán ready to go. Now we’ve got people in Mazatlán who are the trainers.”
Jeremy Main, Senior Vice President, Consolidated Precision Products
The conditions behind that result are structural rather than lucky. Mazatlán’s workforce draws on 21 universities and trade schools with more than 29,000 students, graduating over 5,250 a year, 35 percent of them in engineering and technical fields, into a local economy where manufacturing is still only about a tenth of employment. An aerospace employer there recruits from technical programs without bidding against a street of incumbents, sets compensation norms through benchmarking, and hires in a city people move to on purpose, which is where retention starts.
Aerospace is already the largest industry segment across Tetakawi’s campuses, and the operating playbook that supports it, from mass recruiting to the import of controlled, calibrated equipment, was built over four decades before arriving in Sinaloa. The deepest bench sits in Sonora: the Guaymas and Empalme campuses have hosted gas turbine and aerospace work for decades, with a dedicated on-site CNC machining training center and access to secondary processing, and that is where CPP’s Mexican story started.
No single address is the answer; the network is. The exercise is matching the part family to the labor market. For training-intensive new capacity in 2026, Mazatlán is the market with the most room.
Standing Up Capacity
The practical path matters as much as the location. Inside a Manufacturing Campus, an aerospace supplier operates under a single U.S.-based contract with no Mexican legal entity, in Class A industrial space configured to your process requirements, with recruiting, HR, EHS, and customs compliance run as shared infrastructure. Launches compress to as little as 30 days against the 8 to 12 months a standalone setup requires, and the decision stays reversible in a way a greenfield never is, which is worth something in a year when trade rules change quarterly. How this location compares against others for your specific positions and freight lanes is exactly what our site selection framework and a side-by-side cost model are for; the labor economics of the border alternative are covered in our Tijuana analysis.
The backlog is not waiting. Every quarter a supplier spends unable to staff a rate increase is margin conceded to whoever can. The companies that will own the ramp are deciding now where their next certified bench gets built.

Frequently Asked Questions
Where is the best place in Mexico to manufacture aerospace parts?
It depends on the part family. Software-intensive systems follow deep engineering pools, and large aerostructures belong near final assembly lines. For training-intensive work (engine components, castings finishing, NDT, composites), the deciding variable is certified-labor retention, which favors markets with a strong technical pipeline and limited employer competition. Within Tetakawi’s network, Guaymas offers the most established aerospace cluster and Mazatlán the most headroom for new capacity.
Which aerospace parts make sense to manufacture in Mexico?
Labor-intensive, certification-heavy work is where aerospace manufacturing in Mexico delivers most: engine component finishing and inspection, composite lay-up, precision machining, harness and electro-mechanical assembly, interiors. Large aerostructures are penalized by logistics and metal-heavy trade exposure, and deeply software-dependent systems follow engineering talent instead of labor economics.
How do tariffs treat aerospace parts made in Mexico?
As of this writing: metal-bearing articles on covered tariff lines face U.S. Section 232 duties regardless of USMCA origin, while many low-metal aerospace products fall outside the covered lines or under a weight-based de minimis, and USMCA-qualifying goods have been exempt from the blanket border surcharge. Mitigation is largely documentation: metal-origin certificates, weight substantiation, and in defined cases manufacturing drawback, per White & Case’s analysis. The rules have changed repeatedly in 2026; verify current treatment for your specific products with trade counsel.
How do you build certified aerospace talent in a new location?
The proven pattern is a training flywheel: hire locally from technical programs, qualify the first cohorts at established facilities, return them as the site’s trainers, and let each generation certify the next. It requires a location where trained people stay, which is why retention economics, not wage rates, should anchor the decision.
