Core Responsibilities

Primary Functions

Read, interpret and accurately assemble aircraft subassemblies, structural components and mechanical systems using detailed engineering drawings, specifications, manufacturing orders and bill of materials to ensure parts fit, alignment and function meet engineering tolerance and finish requirements.
Install and secure fasteners, rivets (solid and blind), bolts, nuts, washers and inserts using hand tools, pneumatic rivet guns, clecos, bucking bars and torque wrenches while strictly following torque values, installation sequences and hardware callouts on blueprints and work instructions.
Perform composite layup and bonding operations including cutting, dry layup, wet layup, vacuum bagging, curing and trimming per controlled process sheets, safety data sheets and specified cure cycles to produce structurally sound composite components.
Assemble and install mechanical flight control linkages, actuator mounts, brackets and support structures, verifying proper lubrication, hinge geometry and range-of-motion clearances to meet flight envelope requirements and prevent binding.
Terminate, route and secure electrical and avionics harnesses, connectors and shielding using soldering, crimping, wiring diagrams and wire harness routing plans; perform continuity, insulation resistance and functional checks per electrical schematics and test procedures.
Fit, trim and fasten sheet metal skins, doublers, stiffeners and stringers to airframe structures using clecoing, riveting and sealant application while ensuring skin-to-frame gap tolerances and edge distances are within approved limits.
Conduct in-process and final inspections using calibrated measuring tools — calipers, micrometers, depth gauges, torque wrenches and rivet gauges — documenting nonconformances and performing rework only under authorized procedures.
Apply sealants, adhesives and primers in controlled environments and ensure material traceability, batch numbers and shelf-life compliance for all chemical and bonded assemblies.
Use hand and power tools, fabrication equipment, and small machine shop tools to prepare parts, deburr edges, countersink holes and perform light machining operations necessary for assembly readiness.
Set up and operate assembly jigs, fixtures and racks, ensuring correct tooling configuration, datum alignment and part registration prior to final assembly operations.
Follow manufacturing process specifications, work instructions and standard operating procedures (SOPs) and maintain accurate route cards, traveler documentation and build records for traceability and audit readiness.
Perform functional ground tests and bench tests of installed assemblies—hydraulic, pneumatic, mechanical and electrical—execute test sequences, interpret test results, and record findings consistent with test protocols.
Diagnose assembly fit and functional issues, collaborate with engineers and inspectors to apply corrective actions, implement engineering change notices (ECNs) and update build documentation as required.
Participate in tooling validation, first article inspections (FAI) and qualification builds to validate assembly processes, verify tolerances and ensure initial production meets design intent and customer requirements.
Maintain clean, organized and safe work areas, comply with shop safety programs, lockout/tagout, personal protective equipment (PPE) requirements and hazardous material handling procedures (MSDS/SDS).
Support lean manufacturing and continuous improvement initiatives by identifying waste, suggesting process improvements, documenting time studies and participating in kaizen events.
Prepare and attach identification plates, decals, kitting labels and part serialization; ensure correct part numbers and revision levels are installed and recorded per configuration management practices.
Perform basic non-destructive testing (NDT) aids such as visual inspection, dye penetrant or eddy current preps (where trained), and coordinate with certified NDT technicians for formal inspections.
Train and mentor junior assemblers on best practices, safe tool use, blueprint interpretation, and assembly sequences to raise overall team proficiency and reduce rework.
Maintain strict adherence to quality control standards (AS9100, ISO, FAA FAR Part 145 where applicable), reporting discrepancies immediately and supporting supplier corrective action and internal corrective action processes.
Follow lot control and traceability procedures for hardware and consumables, verifying certificate of conformance (CoC) and maintaining records for audits and regulatory compliance.

Secondary Functions

Support kitting, inventory checks and parts replenishment to ensure uninterrupted assembly flow and reduce line downtime.
Assist quality engineers with data collection for process control charts, defect trending and root cause analysis.
Participate in cross-functional team meetings with engineering, planning and logistics to communicate assembly constraints and improvement opportunities.
Provide detailed feedback on tooling wear and gaging accuracy; request maintenance or calibration as required.
Help prepare product for shipping: package, protect delicate composite surfaces, complete packing lists and verify shipping documentation.
Volunteer for weekend or overtime shifts during production ramps, prototype builds or urgent customer deliveries.
Support training documentation updates and help draft clearer work instructions based on hands-on assembly experience.
Participate in shop safety inspections and suggest corrective actions for ergonomic or process-related hazards.
