A few months back I sat across from the sales lead of a Tier-2 machine shop that had every certificate on the wall. AS9100. Nadcap accreditation for heat treat. A spotless audit history going back years. And almost no new programs coming in. “We are the best-kept SECRET in the supply chain,” he told me, half joking. That line stuck with me, because it is the whole problem in one sentence. In aerospace and aviation manufacturing, being good at the work is the price of admission, not the thing that wins it.
So this guide is built for shops and suppliers like his. Not a recycled list of “post on social media” tips, but the plays that actually fill an OEM or Tier-1 supplier’s order book: how you get qualified, how you get found on the exact spec, how you land on the approved vendor list, and how you turn one build-to-print job into a program that runs for years. Let’s get into it.
Here’s the gist: aerospace buyers qualify you before they ever let you quote, and the people who approve you are not the people who sign the purchase order. Win by clearing the certification gate (Qualify), ranking for the exact process and material a buyer searches (Get found), landing on the approved vendor list (Get on the list), quoting fast and clean (Win the package), and then growing inside a program you already serve (Hold the program). Every play below maps to one of those five stages.
Why is lead generation for aerospace and aviation manufacturers different?
Because you have to be QUALIFIED before you are even allowed to quote. A commercial buyer can try a new vendor on a Tuesday and forget them by Friday. An aerospace prime cannot. Every part that goes onto an aircraft carries safety, traceability, and certification weight, so suppliers get vetted onto an approved vendor list (AVL) long before a single request for quote (RFQ) lands in your inbox. Your lead generation, then, is really about getting onto that list and staying visible to the people who control it.
That changes three things. First, the buying group is layered. A design engineer cares about tolerances, procurement cares about cost and capacity, and the supplier quality engineer (SQE) cares about risk, so a pitch aimed at only one of them falls flat. Second, the cycle is long. From first contact to a production purchase order can run many months, and a multi-year long-term agreement (LTA) takes even longer, so your follow-up has to outlast everyone’s patience. Third, the standards do the talking. AS9100 listed in the IAQG OASIS database, Nadcap for your special processes, and a clean first article inspection say more than any tagline ever could.
And the demand is real, which is why the effort pays off. Airbus projects a need for 43,420 new passenger and freighter aircraft between 2025 and 2044, with the global fleet nearly doubling from 24,730 to 49,210 jets over that window. Boeing’s Commercial Market Outlook agrees that passenger traffic more than doubles across the same 20 years. Every one of those airframes needs forgings, machined parts, fasteners, coatings, and assemblies. The work is there. The trick is being the supplier a prime can find and trust.
Who buys what across the aerospace supply chain?
Each layer of the chain buys something different and answers to a different pressure. If you only ever pitch the primes, you are competing with the whole world for the hardest door to open. Map the tiers first, then pick the entry point that fits your shop.
| Tier | Who they are | What they buy | Your entry move |
|---|---|---|---|
| OEM / Prime | Boeing, Airbus, Lockheed, RTX, GE Aerospace | Major structures, engines, full systems | Get on the AVL through a supplier portal, then earn a package |
| Tier-1 integrator | Spirit, Safran, Collins, Honeywell units | Sub-assemblies, modules, build-to-print kits | Sell up to them, not only the prime; they place more parts more often |
| Tier-2 part maker | Precision machine shops, fabricators, casters | Detail parts, components, tooling | Win build-to-print RFQs, prove on-time delivery, expand the line card |
| Tier-3 / special process | Heat treat, plating, NDT, raw material mills | Materials and Nadcap special processes | Become the approved source others must route work through |
Notice the Tier-1 row. Integrators place far more parts, far more often, than a prime ever will directly. For most Tier-2 shops, the fastest pipeline runs through Tier-1 buyers, not the household-name OEM at the top.
Who actually approves a new aerospace supplier?
Almost never one person, and rarely the first contact you meet. A new-source decision runs through a buying group, and each member weighs a different risk. Speak to only one of them and you sound like every other cold email in the folder. Here is the group I map before any outreach.
| Role | What they own | What wins them over |
|---|---|---|
| Design engineer | Drawings, tolerances, material callouts | Design-for-manufacturability help and proof you can hold the spec |
| Procurement / buyer | Cost, capacity, lead time, the PO | Competitive quote, real capacity, on-time delivery history |
| Supplier quality engineer (SQE) | The AVL, audits, risk, corrective action | Low defective parts per million, clean FAI, fast CAPA response |
Most suppliers market only to procurement. The quiet gatekeeper is the SQE, because they hold the keys to the approved vendor list. So put your quality story where they will see it: defective parts per million (DPPM), on-time delivery (OTD), and first article inspection track record, right on the page. We will come back to that.
11 lead generation plays for aerospace and aviation manufacturers
Here is the part you came for. The first few plays are general methods that work in any B2B manufacturing, sharpened for aerospace. The rest are the niche moves that actually open OEM and Tier-1 doors. Run them in order and you build a pipeline that survives a long program cycle.
1. Clear the certification gate and say so loudly (Qualify)
Start here, because nothing else matters until you pass the gate. AS9100 is the baseline quality standard for aerospace, and for special processes like heat treating, coating, or non-destructive testing you also need Nadcap accreditation. Buyers do not take your word for it. They check your status in the OASIS database, so keep it current and listed. State your certifications in plain sight on every relevant page. A buyer should never have to email you to learn whether you can legally touch their part.
📌 Quick definition: An approved vendor list (AVL) is the roster of suppliers a prime or Tier-1 has already qualified to receive work. Getting added is the real goal of aerospace lead generation. The RFQ only comes after you are on it.
2. Build spec-driven pages for the exact process and material (Get found)
Aerospace engineers do not search for “aerospace machining.” They search for the job in front of them, like “5-axis Inconel 718 milling” or a specific AMS or MIL-SPEC callout. So build a page for each capability, material, and process you own, with the alloys, tolerances, envelope sizes, and standards spelled out. These long, specific pages capture high-intent searches that broad pages never will. Run a small exact-match paid search budget on the same terms and add negative keywords to keep hobbyist traffic out.
3. Get visible inside supplier portals, not just Google (Get found)
Ranking on Google matters, but primes often source inside their own walled gardens. Boeing, for example, runs a structured path for becoming an approved supplier through its supplier portal, and many primes search platforms like Exostar and the OASIS database before they ever open a browser. Register everywhere your target buyers actually look, complete every profile field, and keep your capabilities and certifications accurate. A complete portal profile is a lead source that works while you sleep.
4. Market to the supplier quality engineer, not just procurement (Qualify)
The SQE can veto any new source, so give them what they need to say yes. Publish your DPPM, your on-time delivery rate, your audit results, and how fast you close a corrective action. A short “quality at a glance” section on your site does more selling to this audience than a brochure ever could. When you reach out, lead with risk reduction, because that is the language the gatekeeper speaks.
🔍 Field note: The shops that win fastest put their on-time delivery and scrap numbers above the fold. "99.6% OTD, under 0.5% scrap" reassures an SQE far more than "state-of-the-art facility" ever will.
5. Sell up the chain to Tier-1 integrators (Get on the list)
Chasing only the primes is the slowest path in. Tier-1 integrators buy more parts, more often, and their approval cycles move faster than an OEM’s. Build a target list of integrators whose programs match your capabilities, then approach their commodity managers with a tight capability statement. Teaming and referrals matter here too. A satisfied Tier-1 buyer who vouches for you to a sister division is worth more than any ad you could run.
6. Engage at design, before the print is locked (Win the package)
Cold build-to-print bids are a coin flip. The suppliers who win consistently get involved while the part is still being designed, offering design-for-manufacturability (DFM) input that saves the customer cost and time. Host a short DFM review, publish manufacturability guides for your processes, and ask engineers what is hard to source right now. By the time a print is finished and sent out for quote, the supplier who helped shape it is already the favorite.
7. Use the first article inspection as a low-risk entry offer (Win the package)
Breaking into an entrenched supply chain is hard because the incumbent is “good enough.” So lower the risk of trying you. Offer a tightly scoped first article inspection (AS9102) or a small qualification run on a single part. It gives the buyer proof without committing them to a full program, and it gives you a real reference. One clean FAI is a sales asset you can point to for years, as long as you respect the customer’s confidentiality.
8. Quote fast, quote clean (Win the package)
Speed-to-quote is an underrated lead-gen tool. Buyers remember the supplier who responded in two days with a clear, complete quote, and they forget the one who took three weeks. Build an RFQ intake that captures the drawing, revision, quantity, and need-by date in one step, and route it to a real estimator quickly. A fast, professional quote signals that you will be just as responsive once you are in production.
9. Run account-based outreach to specific prime and Tier-1 divisions (Get on the list)
Aerospace is a small world of named accounts, which makes account-based outreach a natural fit. Pick the handful of divisions whose programs match your shop, learn their commodities, and reach the design engineer, the buyer, and the SQE with a message tailored to each. On LinkedIn, share sanitized process content, like how you hold a tricky tolerance, without ever exposing a customer’s part or anything export-controlled. At trade shows, pre-book meetings with your target Tier-1 buyers months ahead instead of just walking the floor.
10. Watch the supplier-switch triggers (Get on the list)
Primes add or replace suppliers at predictable moments, and timing your outreach to those moments beats cold prospecting every time. A competitor slips below the required quality score (the dreaded red scorecard), a program mandates a second source, or a part revision reopens the package for quote. Track these signals with buyer intent data and program news, then reach out the week a door opens, not months later.
💡 Try this: Set an alert for the transition from low-rate initial production (LRIP) to full-rate production (FRP) on programs you can serve. That ramp is when primes scramble for suppliers who can hold volume, and a ready shop gets the call.
11. Turn a build-to-print win into a long-term agreement and MRO work (Hold the program)
The first purchase order is the start, not the finish. Aircraft programs run for decades, so a single qualified part can become a multi-year long-term agreement (LTA) plus a steady stream of maintenance, repair, and overhaul (MRO) and spares work. Deliver flawlessly on the first job, then ask your buyer what else they struggle to source. Steady nurturing of existing accounts often returns more revenue than chasing brand-new logos, and at a far lower cost.
When should you reach out? The supplier-switch timing grid
Timing decides whether your outreach lands or gets ignored. Here are the moments worth watching and the move that fits each one.
| Trigger | What it signals | Your move |
|---|---|---|
| Red scorecard event | An incumbent missed quality or delivery targets | Offer a qualified second source fast, lead with your OTD and DPPM |
| Dual-source mandate | The prime wants a backup supplier on a sole-sourced part | Pitch risk reduction and capacity, not lowest price |
| LRIP to FRP ramp | A program is scaling from prototype to full volume | Show you can hold rate and quality at higher quantities |
| Engineering change notice | A revision reopens a part for new tooling or quote | Quote the revised package fast with DFM input |
| OASIS certification lapse | A competitor lost or let an accreditation expire | Reach the affected buyer while your certified status stands out |
What do aerospace manufacturing marketing benchmarks look like?
Aerospace marketing rewards quality of engagement over raw volume, and the numbers prove it. These figures come from our own aerospace and aviation manufacturing marketing benchmarks, and they are worth pinning to the wall before you set targets.
| Metric | Benchmark | What it tells you |
|---|---|---|
| Google Ads CPC | $4.85 to $12.50 | Clicks are expensive, so exact-match and negatives matter |
| Paid conversion rate | 2.8% | Solid for a long, technical buying cycle |
| Cost per qualified RFQ | $135 | Each real quote request is worth chasing |
| Site-wide conversion | 1.8% | Conversions are RFQ submissions, not checkouts |
| Email open rate | 24.5% | Vetted lists open, so keep them clean and small |
| LinkedIn engagement | 1.4% | The dominant social channel for this audience |
| Customer retention | 94% | Long programs reward keeping the accounts you win |
The story those numbers tell is simple. Clicks cost a fortune, but a kept customer stays for years, so your money is better spent on getting found by the right buyer and then never letting that account slip.
What mistakes cost aerospace suppliers the most leads?
Most lost pipeline traces back to a handful of avoidable habits. I see these on nearly every audit.
- One generic capabilities page. A buyer searching for a specific alloy and process will never find a page that lists everything you do at once.
- Marketing only to procurement. Ignore the supplier quality engineer and you skip the person who actually controls the approved vendor list.
- Chasing primes only. The Tier-1 integrators place more work, more often, and approve suppliers faster.
- Cold-bidding without design input. If the first time you talk to a customer is the RFQ, the package was probably shaped around someone else.
- No compliance story. For defense work, gaps in NIST SP 800-171 controls and CMMC readiness get you dropped before you start. Selling to government primes also means tighter B2G prospecting and ITAR awareness.

Frequently asked questions
How do aerospace and aviation manufacturers generate leads?
They generate leads mainly by getting qualified and getting found, not by running broad ads. The reliable mix is AS9100 and Nadcap certification, spec-driven pages for each process and material, visibility inside supplier portals and the OASIS database, account-based outreach to primes and Tier-1 integrators, and steady nurturing of long buying cycles. The real goal is landing on an approved vendor list, because that is where the RFQs come from.
How do you become an approved aerospace supplier?
You become approved by passing the customer’s quality and compliance vetting, then registering through their supplier portal. Most primes require AS9100, Nadcap for any special processes, and a clean first article inspection. After you register and pass the audit, you are added to the approved vendor list and can receive RFQs. The European route runs through production organisation approval under EASA rules, and the FAA equivalent for parts is Parts Manufacturer Approval.
Do you need AS9100 to win aerospace manufacturing contracts?
In most cases, yes. AS9100 is the standard quality requirement across aerospace and defense, and primes and Tier-1 integrators rarely add a supplier without it. For special processes such as heat treating, coating, or non-destructive testing, you also need Nadcap accreditation. A few low-risk commercial parts may slip through with ISO 9001 alone, but planning for AS9100 is the safer bet if you want production work.
How do small machine shops get on an OEM approved vendor list?
Small shops get on the list fastest by going through Tier-1 integrators rather than straight to the prime. Register in the relevant supplier portals, lead with a tight capability statement, and offer a low-risk first article or qualification run on a single part. Strong on-time delivery and low scrap on that first job build the track record that earns a spot on the wider vendor list.
Should we gate our AS9100 and Nadcap certificates or leave them public?
Leave your certification status public. Buyers and supplier quality engineers want to confirm you are qualified before they spend a minute on you, and hiding that behind a form only adds friction. List your AS9100 scope, your Nadcap special processes, and your major customer approvals openly. Save gating for deeper assets like detailed capability decks, where capturing a contact is worth the trade.
How long is the sales cycle in aerospace manufacturing?
It is long, usually many months from first contact to a production purchase order, and longer still for a multi-year agreement. Qualification, audits, and first article approval all add time before any revenue arrives. That is why retention matters so much here, with kept customers staying for years, and why your nurturing has to be patient and consistent rather than pushy.
How do you market a Nadcap special process without breaking ITAR or an NDA?
Focus on the process, never the customer’s part. You can describe your accredited capability, the materials and tolerances you hold, and your quality results without showing a controlled drawing or naming a program. Use sanitized or generic examples, keep export-controlled technical data off public pages, and route anything sensitive through a vetted, gated channel. The capability sells the work, and you stay compliant with ITAR and EAR.
What is the best way to turn a build-to-print RFQ into a long-term agreement?
Deliver the first job flawlessly, then expand the relationship before the buyer goes looking. Hit every delivery, keep your quality scores high, and ask your customer what else they struggle to source. Propose a long-term agreement that locks in pricing and capacity for parts you already make well, and offer to take on the related MRO and spares work. Reliability, not a discount, is what converts a one-off RFQ into a program.
Bringing it together
Here is the thing to remember. In aerospace and aviation manufacturing, the best supplier does not always win the work. The findable, qualified, well-timed supplier does. So clear the certification gate, build pages for the exact specs buyers search, get visible where primes actually source, speak to the supplier quality engineer, and time your outreach to the moments a door opens. Then hold on tight, because these programs run for years.
You do not have to run all eleven plays at once. Pick the two that fit your shop this quarter, do them well, and build from there. You’ve got this, and when you are ready to put real target accounts in front of your team, CUFinder is here to help you find them.
