What is a Pre-Production Inspection (PPI)?
A Pre-Production Inspection (PPI), also known as a First Article Inspection (FAI), is performed on raw materials and the first-run product before mass production begins. It verifies that all engineering, design and specification requirements are correctly understood and that the prescribed production methods will deliver an acceptable item as specified by your drawings, purchase order and standards.
- Verifies raw materials, components & accessories
- Assesses production lines, capability & equipment
- Checks the first 10-30% of production units
- Early detection of issues before mass production
What We Check in a PPI
Starting in aerospace and now common across all critical components, the PPI confirms the factory can produce acceptable items to your specifications before mass production begins.
Raw Materials & Components
Verify materials, main components and accessories meet your specifications.
Production Lines & Capability
Assess the production process, output capacity and readiness.
Facilities & Equipment
Verify machinery, tools and facility conditions are suitable for production.
First-Run Samples
Check the first 10-30% of units produced against the required criteria.
Production Schedule
Verify the production progress and on-time delivery capability.
Semi-Finished & Finished Goods
Spot-check quality, function and workmanship of early production.
Benefits of a Pre-Production Inspection
Early Warning
Identify and rectify defects before mass production.
Quality Control
Take control of quality from raw materials and procedures.
Immediate Reporting
Non-conformities reported at once to avoid shipping delays.
Measure Manufacturer
Assess the factory's ability to meet your requirements.
Reduce Risk
Diminish the risk of supply-chain interruption.
24-Hour Report
Detailed photographic report delivered within 24 hours.
When to Consider a PPI
A PPI keeps your suppliers in check, your orders shipping on time and your quality consistent from the very first unit.
New Manufacturer
When working with a new manufacturer or supplier, ensure the factory meets your requirements.
Large Orders
When booking a large order, address any issues before mass production begins.
Long Production Runs
When the manufacturing process spans several months, verify the first output is correct.
Comprehensive Inspection Reports
Every PPI report documents the production readiness, materials, first-run samples and capacity with detailed photos, together with a clear conclusion that lets you start mass production with confidence. The report is delivered within 24 hours of the inspection.
