Abstract	This study examined the quality performance of a Batangas-based aerospace manufacturing company over two years (2023–2024) using four key performance indicators (KPIs): Defects per Unit (DPU), First Pass Yield (FPY), Customer Rejection Rate in Parts per Million (PPM), and Nonconformity Closure Rate measured through Turnaround Time (TAT). An explanatory sequential mixed-method design was employed, wherein quantitative trend analysis was conducted first to identify performance patterns, followed by qualitative inquiry to explain the observed trends.
