Performed testing, inspection, assembly, and disassembly of aircraft components, ensuring compliance with CMM (Component MaintenanceManual), IRM (Illustrated Repair Manual), and OEM specifications. Conducted troubleshooting and root cause analysis on pneumatic, hydraulic, and APU components to enhance system reliability. Managed Turnaround Time (TAT) to ensure on-time component delivery, preventing Aircraft on Ground (AOG) scenarios for airline customers. Performed diagnostic and performance testing, including Leakage, Dielectric, Continuity, and Proof Pressure tests. Reviewed and updated CMM and IRM revisions, ensuring maintenance procedures align with the latest manufacturer standards. Reviewed and updated routing documents to record unit-specific parameters and ensure accurate maintenance tracking. Created and maintained test data sheets to document component performance and compliance with regulatory requirements. Utilized precision measuring instruments (Dial Gauge, Vernier Caliper,Micrometer) to verify component tolerances and ensure airworthiness. Key Achievements: -Optimized APU repair procedures, decreasing standard labor hours while maintaining compliance and operational efficiency. -Successfully conducted FAA audit with zero compliance issues.
