Install and route electrical harnesses, avionics components and associated hardware, secure connectors and backshells, and verify harness continuity and routing conforms to engineering and safety standards.
Use precision measuring instruments including calipers, micrometers, height gauges and torque wrenches to verify dimensions and torque values, and document inspection results to maintain traceability.
Perform in-process dimensional checks, laydown inspections and final assembly verifications including first article inspection (FAI) readiness, ensuring parts meet acceptance criteria before release.
Execute nondestructive inspection (NDT) tasks such as visual inspection, dye penetrant (fluorescent and visible), eddy current and magnetic particle inspections per established procedures and report findings to quality engineering.
Setup and rig components to tooling, jigs and fixtures; check and adjust fixture alignment and datum references to ensure consistent repeatability across assemblies.
Troubleshoot assembly issues, escalate discrepant conditions, propose and document engineering deviation requests (EDRs) or material review board (MRB) submissions when nonconforming parts are identified.
Maintain accurate production travelers, SAP/MES/ERP records, work orders and inspection documentation, including sign-offs for specific operations and traceability of serial numbers and lot codes.
Perform final system functional tests and operational checks (mechanical motion, control surface rigging, ground power checks) per test procedures and sign off on completion and readiness for next process.
Adhere to FAA, EASA and company regulatory requirements, airworthiness directives and repair station procedures where applicable, ensuring all work meets certification standards.
Execute FOD prevention practices, maintain shop cleanliness, organize tooling and consumables, and perform pre- and post-shift tool accountability and calibration checks to support safety and quality.
Participate in continuous improvement, lean manufacturing and 5S initiatives to reduce cycle time, eliminate waste, and improve assembly ergonomics and throughput.
Mentor and train junior assemblers and apprentices on shop procedures, tooling use, safety practices, quality expectations and best practices for aircraft assembly processes.
Support root cause investigations, corrective actions and CAPA implementations when defects or process deviations occur, coordinating with quality and engineering to validate fixes.
Complete required safety and job-specific training (hazmat handling, confined space, hoisting/rigging, fall protection), follow lockout/tagout procedures and use personal protective equipment (PPE) consistently.
Perform scheduled maintenance and minor repair work on fixtures, jigs and production tools, and coordinate with maintenance teams for complex repairs or replacements.
Participate in production planning discussions, provide assembly time feedback, and assist material kitting or line balancing activities to support on-time delivery commitments.
Execute weight and balance checks and verify installed component weights and locations against engineering documentation for accurate aircraft configuration control.
Support flight test and final acceptance activities by preparing assemblies for ground run-ups, taxi tests and flight test instrumentation installation when required.

Secondary Functions

Assist quality and engineering with root cause data collection during inspections and provide hands-on feedback to improve manufacturability and assembly instructions.
Coordinate with material control and purchasing to report shortages, damaged goods or nonconforming supplier parts and support supplier corrective action follow-up.
Help maintain and calibrate hand tools, torque wrenches, measuring instruments and jigs, and log calibration certificates in compliance with control requirements.
Provide input for standard work documents, assembly instructions and training aids; update job cards to reflect process improvements or corrective actions.
Support cross-functional audits and supplier inspections by preparing documentation, part samples and demonstrating assembly processes to auditors.
Participate in continuous learning sessions on new materials, updated engineering specifications and regulatory changes to maintain current competencies and certifications.
Assist in the preparation and staging of kits and subassemblies for upcoming production builds and help ensure accuracy of pick lists and BOM compliance.
Support ergonomics and workstation improvement initiatives by testing jig modifications or new tooling and documenting impact on cycle time and quality.
Participate in scheduled shutdowns or production changeovers, helping to disassemble, reconfigure or validate fixtures and tooling as needed.
Contribute to digital manufacturing adoption by inputting accurate work data into MES systems and proposing automation opportunities for repetitive tasks.
