Entering aerospace from another industrial sector: what changes and what does not

Many industrial companies with solid capabilities in precision manufacturing, advanced materials, surface treatments or complex assembly processes see aerospace as a natural next step. The sector offers long-term contracts, premium pricing and the credibility that comes with operating in a demanding regulated environment. But the path is rarely straightforward.

The qualification barrier is structural, not bureaucratic

The first thing companies discover is that the entry barrier in aerospace is not primarily commercial — it is systemic. Customers such as Airbus, Leonardo or Safran do not simply evaluate a supplier's product or price. They evaluate the entire system behind it: quality management, production control, traceability, on-time delivery performance and financial stability.

Certification under standards such as EN 9100 (the aerospace equivalent of ISO 9001) is a prerequisite, not a differentiator. Without it, the conversation cannot even begin. But obtaining it does not mean landing a contract — it means becoming eligible to be evaluated.

"In aerospace and defence, the approval process for new suppliers typically takes between 18 and 36 months and involves multiple on-site audits, first-article inspections and production trials before any commercial volume is awarded." — Deloitte, Aerospace & Defense Industry Outlook, 2024

What genuinely transfers from other sectors

The good news is that many industrial capabilities do transfer — if they are positioned correctly. A company with a strong track record in automotive Tier 1 (IATF 16949, PPAP processes, APQP methodology) or in medical devices (ISO 13485) already understands the language of regulated manufacturing. The documentation culture, the focus on root cause analysis and the discipline around non-conformances are directly applicable.

Similarly, companies operating in energy, rail or defence typically have experience with long commercial cycles, multiple decision-makers and technically demanding customers — all of which are directly relevant in aerospace.

What genuinely does not transfer

The most common misconception is that a good product is sufficient. Research from McKinsey's Aerospace & Defence practice consistently shows that first-tier aerospace customers make supplier decisions based on three factors in order: systemic reliability, technical capability, and then commercial terms. Price is rarely the deciding variable in initial qualification.

A second frequent mistake is underestimating the importance of sector-specific visibility. Aerospace procurement teams attend specific trade events (Paris Air Show, Farnborough, DSEI), reference specific industry databases (Airbus SQIP, Leonardo Supplier Portal, Safran Achats) and operate through networks that are largely invisible to outsiders. Being technically qualified but commercially invisible is a common failure mode.

The three phases of a realistic entry path

Based on experience supporting industrial companies in market access processes, a realistic aerospace entry strategy typically unfolds across three phases:

• Preparation (6–12 months): Gap analysis against EN 9100, internal process alignment, identification of target customers and sub-tiers where entry is more accessible than at prime contractor level.
• Visibility and qualification (12–24 months): Active participation in sector events, direct outreach to procurement and supply chain teams, first-article qualification with a selected customer, development of a reference contract even at small volume.
• Consolidation (ongoing): Leveraging the first reference to access additional customers, expanding the portfolio of approved processes, developing relationships at engineering level (not only procurement).

"Suppliers that enter aerospace through the sub-tier route — becoming Tier 2 or Tier 3 before targeting Tier 1 — are significantly more likely to achieve stable, long-term revenue than those targeting prime contractors directly." — Roland Berger, Aerospace Supply Chain Strategies, 2023

A note on timing and resource commitment

One of the most valuable insights from Harvard Business Review's research on B2B market entry is that companies consistently underestimate the time and overestimate the speed of commercial return in new sectors with structural barriers. In aerospace, the average time from first customer contact to first production order is between 2 and 4 years for a new supplier — even when the supplier's capabilities are genuinely differentiated.

This does not mean aerospace is inaccessible. It means that the decision to enter should be treated as a strategic investment with a defined 3–5 year horizon, not as a short-term revenue diversification move.

At BD Management, we support industrial companies through exactly this kind of structured market access process — from capability assessment and qualification preparation to targeted outreach and opportunity development in aerospace and adjacent sectors.
