The cleanest way to read Mexico’s aerospace industry in 2026 is not as a single cluster. It is five regional clusters with distinct specializations, anchored by a different set of OEMs from the ones that anchor the country’s automotive story, and operating under a tariff regime that is fundamentally friendlier than the one weighing on autos — at least until the Section 232 commercial-aircraft investigation delivers its determination, which is now days or weeks away.
The cluster pattern is real
Querétaro is the most concentrated tier-1 footprint. Bombardier opened its plant in 2006, has invested roughly $500 million cumulatively, and now employs around 2,200 people building rear fuselages for the Global 7500 and Global 8000 ultra-long-range business jets, plus structural systems for the Challenger 3500. In October 2025 Bombardier announced an additional $18 million investment and 246 specialized jobs, and the company’s vice president of transformation publicly described Querétaro as the firm’s largest manufacturing site outside Canada. Safran is the larger employer — roughly 16,000 people across Mexico, of whom 4,000 are in Querétaro across eight production sites — and committed more than $163 million in Q4 2025 alone across three concurrent expansions: Aero Composites for LEAP fan components, Landing Systems Services Americas for long-range landing-gear MRO, and Aircraft Engine Services Americas for two new engine test benches. GE Aerospace runs a 26-year-old engineering center in Querétaro with more than 1,000 engineers — a design and analysis hub rather than a manufacturing plant — that owns lifecycle engineering for the LEAP and other commercial propulsion programs. Aernnova grew from 498 to 750+ employees across 2024 and 2025 and broke ground on a new composites plant in early 2026. Diehl Aviation took an 8,000 m² footprint in March 2025 with capacity to recruit up to 500 staff over three years.
Chihuahua is the second-largest cluster by volume and the most diverse by program. The state hosts 52 active aerospace companies, 46 certified suppliers, and five aerospace OEMs — the highest count in the country — supporting roughly 17,000 direct jobs. Honeywell’s Chihuahua plant, opened in 2006 and now spanning five buildings with more than 1,300 CNC machines, is Honeywell’s largest mechanical manufacturing site globally. Textron Aviation operates seven separate plants making nearly all wiring harnesses, fuselages, and structural components for Cessna and Beechcraft platforms, with the assembled subsections shipped to Wichita for engine integration. Bell builds 80%+ of its commercial helicopter cabins and fuselages in Chihuahua. EZAir, the Safran-Embraer joint venture established in 2013, employs 1,100 people producing E-Jet E1 and E2 cabin interiors. Chihuahua attracted $95.3 million in aerospace FDI in 2024 — 28% of the national total.
“Querétaro is now Bombardier’s largest global location for component manufacturing, supported by a mature aerospace ecosystem that includes engineering centers, technical training institutes, and a growing supplier network.”
Baja California is the largest cluster by company count. Mexicali, Tijuana, and Ensenada together host roughly 130 aerospace firms employing 37,000 people. Honeywell Aerospace Mexicali sits on Circuito Aerospacial No. 2, building turbine components and auxiliary power units. Collins Aerospace, Safran, and GKN all run Mexicali operations. CPP Ensenada provides AS9100 / Nadcap-accredited finishing, machining, and welding for stainless, titanium, and aluminum castings feeding US assembly lines.
Sonora has consolidated as Mexico’s “turbine capital,” with roughly 70 companies and 20,000 direct aerospace jobs. Latécoère runs four plants in Hermosillo employing more than 1,500 people on aerostructures, interconnection systems, and composites for Boeing 737/767/777, Airbus A320/A350, and the full Bombardier and Safran product lines. Williams International operates an engineering footprint in the Hermosillo–Guaymas corridor. GE Aerospace announced a $28.8 million Hermosillo investment in 2025 to modernize its rotating-parts plant. In January 2026, Latécoère and the Sonora state government announced the state’s first dedicated aerospace academy in partnership with Boeing — a workforce-pipeline play tied directly to OEM customer demand.
Nuevo León is smaller — roughly 33 firms, mostly Tier-2 manufacturing — but is the only cluster outside the four anchors with active OEM expansion plans.
The composite picture is unusually balanced for an emerging aerospace economy. No single region dominates, no single OEM is irreplaceable, and the program mix runs from business jets to commercial cabin interiors to landing gear MRO to turbine components to defense-helicopter structures.
The MRO layer
Commercial MRO in Mexico generated approximately $1.0 to $1.3 billion in 2025 and is forecast to scale toward $1.5 to $1.8 billion by 2030–2033. The single largest installation is TechOps Mexico in Querétaro — Latin America’s second-largest MRO footprint, with roughly one million square feet, 1,700–2,000 technicians, 12 active base-maintenance lines (planned to reach 16), and theoretical capacity of 80 aircraft per year. In Q4 2025, Aeroméxico and Delta each sold their remaining stakes in TechOps to MRO Holdings — generating $71 million in extraordinary income for Aeroméxico — leaving MRO Holdings as full owner with both airlines continuing as customers under long-term commercial agreements at competitive rates.
Volaris began operations of a new 16-aircraft maintenance base in Jalisco in January 2026, built with Grupo Aeroportuario del Pacífico (GAP), to support its 152-aircraft fleet through the lingering Pratt & Whitney GTF engine inspection backlog. Viva Aerobus committed MX$4 billion (~$232 million) toward a wide-body MRO facility in Querétaro. Aeroméxico continues to operate three maintenance lines at Mexico City International (AICM) plus a $10 million Guadalajara facility. The federal government allocated MX$1.5 billion in 2025 to retrofit the legacy Mexicana MRO infrastructure at AICM for up to twelve simultaneous wide-body positions.
Tariffs hit aerospace differently
The line that everyone exporting from Mexico cares about — the difference between USMCA-protected zero-tariff entry and a Section 232 stack — is much friendlier for aerospace than for autos. Three independent mechanisms hold that result.
The first is the Bilateral Aviation Safety Agreement (BASA) between the FAA and Mexico’s Agencia Federal de Aviación Civil (AFAC). Mexico regained Category 1 status in September 2023 after a two-year downgrade, and BASA gives FAA-equivalent airworthiness certification recognition to civil aeronautical components produced in Mexico. The practical effect is that a Mexican-made fuselage section, engine module, or avionics unit ships into US final assembly with an export certificate the FAA recognizes natively — no secondary US validation, no duplicate inspection. BASA is the legal bedrock of every program in this section.
The second is USMCA aerospace-content rules. Unlike the automotive chapter — which requires 75% Regional Value Content rising to a proposed 85% under the joint-review investigation — Chapter 4 applies a 67.5% RVC threshold to aerospace via either the Transaction Value or Net Cost method. That lower bar makes the vast majority of Mexico-built aerostructures, engines, landing gear, and avionics duty-free under USMCA without requiring deep supply-chain restructuring.
The third is what Section 232 actually covers. The April 2025 Section 232 expansion to steel and aluminum (now at 50%) carries a major aerospace-relevant carve-out: components composed of metal sourced from at least 95% US-origin smelt are tariffed at only 10%, and components with less than 15% metal content (most carbon-fiber composite assemblies) are exempt entirely. The 15% Section 122 surcharge that took effect February 24, 2026 explicitly exempts civil aircraft and USMCA-compliant goods via Annex II and HTS lines 9903.03.05, .07, and .08.
The current posture, then, is the friendliest tariff environment in major manufacturing — but with one specific binary outcome pending in Washington that could materially shift it before mid-2026.
What’s missing
Mexico’s aerospace footprint is the world’s best second-tier manufacturing base. It is not — yet, and may never be — the world’s best first-tier aerospace base. Four constraints make that distinction concrete.
The first is supply-chain depth. FEMIA’s own data shows that Boeing works with 26 Mexican suppliers, Airbus with 36, and Embraer with 13 — meaningful figures, but a fraction of the hundreds of suppliers each OEM relies on in their home base. The Tier-2 and Tier-3 layers in Mexico are structurally hollow, which means most high-precision components and specialty alloys still arrive at Mexican final-assembly lines from imports rather than from local production.
The second is ITAR. The International Traffic in Arms Regulations (22 CFR §120) restrict non-US persons from physical and digital access to US Munitions List hardware. Manufacturing License Agreements approved individually by the Directorate of Defense Trade Controls are required for any Mexican facility to handle ITAR-controlled programs. The practical effect is that the highest-margin defense and next-generation avionics work — the work Brazil’s Embraer and Morocco’s Casablanca cluster have been able to bid for via different sovereign frameworks — is fenced off from Mexican plants.
The third is research and development. Roughly 13% of Mexico’s aerospace operations fund any institutional R&D, leaving the cluster predominantly as an executor of designs originating in Toulouse, Seattle, Montréal, or Wichita. UNAQ’s master’s and doctoral programs are working to change that, and GE Aerospace’s CFM RISE work in Querétaro represents the kind of advanced-program engagement that builds local intellectual capacity, but the gap remains.
The fourth — and the most material for any customer evaluating Mexico against Brazil — is the absence of a domestic OEM. Brazil has Embraer, which delivered 244 aircraft in 2025 on $7.58 billion in revenue and an all-time-high $31.6 billion firm-order backlog. Morocco has aircraft assembly lines on the roadmap by 2030 per its industry minister. Mexico has Horizontec — a small Celaya-based general-aviation OEM that achieved national certification in 2026 — and not much else at the airframer level. The implication is that Mexico cannot capture the design, IP, and aftermarket margins that an indigenous OEM generates. The country’s aerospace ascent has been, and for the foreseeable future will remain, an extraordinarily high-quality contract-manufacturing story.
That is not a small thing. Mexico exports $13.6 billion of aerospace product per year, employs 60,000 specialists, and sits one to four days by truck from every US final-assembly line. Those facts, plus BASA and a 67.5% USMCA RVC, are the substantive argument. The honest framing is that Mexico is competing in a different category than Brazil — and winning, in that category, by a wide margin.
