Sourcing and certification bottlenecks increase lead times for critical semiconductor components

In early 2026, high-reliability semiconductor sourcing controls were tightened across aerospace and defense tiers due to counterfeit component cases. Multi-year FAA and EASA recertification cycles for obsolete semiconductor nodes (45–65 nm) continue to create structural bottlenecks when substituting parts. Rising semiconductor input costs are increasingly slowing production workflows and driving higher overall system costs for OEMs.
