Most freight brokers stay away from aerospace because it looks complicated. The documentation is unfamiliar, the shippers have rigid approval processes, and the margins aren't obvious from the outside. That combination creates exactly the conditions where informed brokers can build durable, high-margin books. The barrier isn't insurmountable — it's just real enough to keep out brokers who won't do the work to understand the industry.
What Aerospace Freight Actually Moves
Aerospace freight covers a broader range than most people assume. The obvious category is aircraft components — fuselage sections, wing assemblies, engine components, landing gear, and avionics. But aerospace supply chains also include raw materials (titanium billets, aluminum extrusions, specialty composites), tooling, ground support equipment, and test fixtures.
Defense aerospace adds a layer of complexity with export controls (ITAR — International Traffic in Arms Regulations) and security requirements that are separate from commercial aviation. Some brokers specialize within defense aerospace; others avoid it entirely because of the compliance overhead. It's worth knowing the distinction when prospecting.
MRO (Maintenance, Repair, and Overhaul) is one of the most active freight-generating segments in aerospace. Aircraft in service need constant parts replacement. MRO facilities at airports and in industrial parks near major hubs receive and ship parts continuously. This segment also generates AOG freight — more on that below.
Cargo types span the spectrum from small, lightweight avionics components (high value, standard packaging) to massive structural assemblies that require specialized transport. The common thread is that regardless of size or weight, aerospace shippers expect documentation to be complete and accurate, and they expect carriers to handle product as specified.
Documentation That Separates Aerospace Brokers From Spot Operators
The documentation requirements in aerospace are the clearest differentiator between brokers who know the vertical and those who don't.
AS9100 is the quality management standard for the aerospace industry — an extension of ISO 9001 with aviation-specific requirements. Aerospace manufacturers don't require their freight brokers to be AS9100 certified, but brokers who understand what the standard means — traceability, documented processes, controlled handling — communicate credibly with procurement and traffic managers who live inside quality management systems every day.
Certificate of Conformance (CoC) is a supplier-provided document certifying that a part meets its drawing and specification requirements. When a shipper says "this shipment needs to stay with its paperwork," they often mean the CoC must travel with the parts and arrive intact. Losing or separating the paperwork from the hardware is a serious error — the receiving facility may refuse the shipment or quarantine it until documentation is reconstructed.
Controlled shipping refers to parts that are moving under a special quality hold, typically because a supplier had a quality escape and needs enhanced inspection before parts reach the production line. When a shipper tells you a shipment is on controlled shipping, that's elevated urgency — their customer is watching every move.
Bill of lading discipline matters more here than in most other verticals. Part numbers, quantities, and lot numbers must match exactly. A BOL with a transcription error on a part number creates downstream receiving problems that reflect on the broker, not just the carrier.
Equipment Types by Part Category
| Part Category | Typical Equipment | Special Requirements |
|---|---|---|
| Small parts, avionics, instruments | Dry van, sometimes expedite van | Climate-controlled storage in some cases |
| Engine components, nacelles | 48' or 53' dry van | Proper blocking and bracing, engine stands |
| Large structural assemblies | Flatbed, step deck, RGN | Overdimensional permits, escort if required |
| Fuselage sections, wing spars | Specialized transport (lowboy, multi-axle) | Engineering review, route survey |
| Sensitive electronics, flight computers | Climate-controlled van | ESD (electrostatic discharge) precautions |
For most aerospace freight, standard dry van equipment with proper blocking and bracing handles the load. The complication is not always the equipment — it's the documentation and handling protocols. A carrier who throws a pallet of avionics in without securing it properly has created a warranty claim, not just a damage claim.
Major Aerospace Production Clusters
Seattle/Tacoma (Puget Sound) is the largest commercial aircraft manufacturing cluster in North America. The supply chain feeding Boeing's production extends throughout Washington, Oregon, and into the Midwest. Parts suppliers in Wichita, Tulsa, and across the industrial Midwest regularly ship to the Pacific Northwest.
Wichita, Kansas calls itself the Air Capital of the World — Cessna (Textron), Spirit AeroSystems, and a dense network of tier-2 and tier-3 suppliers operate there. Wichita generates significant inbound and outbound aerospace freight.
Southern California (Los Angeles basin, Mojave) hosts defense aerospace — Northrop Grumman, Lockheed's facilities, and SpaceX. ITAR-controlled freight is more prevalent here.
Monterrey, Mexico and the broader Bajío region have become major aerospace manufacturing centers. Mexican aerospace production has grown substantially over the past 15 years, with over 300 aerospace companies operating in Mexico. Cross-border aerospace freight between Mexico and US aerospace hubs is a growing and underserved lane.
Connecticut and New England are home to Pratt & Whitney (engine components) and a cluster of precision machining suppliers feeding commercial and defense programs.
Why Aerospace Carrier Relationships Are Exceptionally Durable
Aerospace shippers qualify their logistics providers. Getting on an approved supplier list requires completing a questionnaire, often providing evidence of insurance, references, and process documentation. Once a broker is on the approved list, shippers are highly motivated to keep using them — qualifying a new provider is work they don't want to repeat.
This creates stickiness that doesn't exist in spot freight. A broker who has served an aerospace tier-1 supplier for three years without a documentation incident is not going to be replaced because a competitor offered a rate 5% lower. Switching costs are real: the new broker has to be qualified, trained on the shipper's specific requirements, and trusted to handle sensitive freight without supervision. That takes time the shipper doesn't want to spend.
The flip side is that the barrier works both ways. Breaking into a new aerospace account takes patience. Procurement managers in aerospace don't take unsolicited broker calls and immediately hand over shipments. The entry path is typically through a warm introduction, a demonstrated track record in adjacent freight (industrial, high-value), or taking on a test shipment that allows the shipper to evaluate execution.
AOG Freight: Aircraft on Ground
AOG (Aircraft on Ground) is one of the few freight categories where cost is genuinely secondary to speed. When an aircraft is grounded due to a missing part, the operator is losing tens of thousands of dollars per hour in lost revenue. A regional airline with a grounded aircraft loses the day's flights on that airframe. A cargo carrier loses freight commitments.
AOG freight moves at any hour, any day of the week, with whatever mode is fastest — expedite van, charter air, next available commercial flight with a handler. The rates are extreme by standard freight standards and completely rational given the downtime cost.
MRO facilities generate AOG requests. Airlines generate them when aircraft go technical unexpectedly. For a broker with relationships in aerospace, being the person who answers the phone at 2 AM for an AOG request and actually delivers is worth more to account retention than 50 routine shipments.
AOG handling requires a network of carriers who can respond quickly and drivers who understand that speed and reliability are the only variables that matter on these moves.
How to Break Into Aerospace
The OEM (original equipment manufacturer) is not the first target. Boeing and Lockheed's logistics operations are handled by large, established providers with deep relationships. The entry point is the supply chain below — tier-1, tier-2, and tier-3 suppliers who manufacture components and sub-assemblies.
A precision machining shop making titanium brackets for aerospace that ships 10-20 loads per month is a realistic target. They need reliable, documentation-compliant brokerage service. They are often underserved by large brokers who don't prioritize smaller accounts, and they don't have the procurement infrastructure to fully qualify dozens of carriers themselves.
From there, relationships compound. A broker who handles five tier-2 suppliers credibly will eventually get referrals to tier-1 suppliers, and sometimes to the OEM's traffic department when they need surge capacity.
Frequently Asked Questions
What is AOG freight and how do I handle it?
AOG stands for Aircraft on Ground — freight that must move immediately because a grounded aircraft is waiting for it. AOG shipments move on expedited terms, typically at 3-5x normal rates or more depending on urgency. Handling AOG requires a carrier network that can respond in hours, not days, and a broker who can project manage the move in real time. If you advertise AOG capability, you need the infrastructure to deliver on it at 11 PM on a Saturday.
Do I need aerospace certifications to broker aircraft parts?
No federal certification is required to broker aerospace freight with your standard broker authority. However, individual shippers may require you to complete their supplier qualification process, which varies. Some shippers require evidence of a documented quality management system; others just want references and insurance certificates. Understanding what AS9100 means and being able to speak intelligently about traceability and controlled handling is what gets you taken seriously, regardless of whether you hold a formal certification.
What makes aerospace freight different from other industrial freight?
Three things: documentation precision, zero tolerance for unauthorized carrier substitution, and the AOG dynamic. Aerospace shippers accept no surprises. If you told them the freight would move on carrier X, and you substituted carrier Y without notification, that's a compliance event in their quality system. The value density is also high — a small box of avionics components can be worth more than a full flatbed of steel.
How do I find aerospace manufacturer accounts?
The FAA maintains a public database of repair stations (MRO facilities). The Aerospace Industries Association (AIA) and state aerospace councils publish member directories. NAICS codes 336411 (aircraft manufacturing) and 336412 (aircraft engine manufacturing) filter industrial databases. Aerospace production clusters are geographically concentrated — prospecting in Wichita, the Puget Sound, or Southern California gives you density. Local business publications in those markets regularly cover aerospace supplier expansions and new facility openings.
What documentation do aerospace shippers require?
At minimum: accurate BOL with part numbers, quantities, and lot numbers; proof of delivery with timestamp and signature; carrier identity disclosure. Many shippers also require GPS tracking records for high-value shipments and chain-of-custody documentation showing the shipment moved without unauthorized stops or transfers. For ITAR-controlled defense freight, additional export documentation is required and brokers need to understand export compliance basics.
