Prime Testing Potential – Brackets /Clips Example • Airbus A350 requires 8,000 Clips per aircraft. • Daher-Socata manufactures 10 Airbus A350 per month • A350 production will increase in time requiring more clips and brackets. • Boeing 787 requires similar outputs of Clips/brackets per aircraft. Current production goal is 10 aircraft per month. Ultimate goal is 20 aircraft/month
