Cut, shear, saw, and trim aluminum, stainless steel and other authorized alloys using hand tools and powered equipment (band saw, nibblers, shears) while following tool-specific safety and maintenance procedures.
Form, bend and shape sheet metal parts using brakes, rollers, English wheel, bead roller and other forming tools to produce aircraft skins, doubler plates, ribs and brackets to specified radii and tolerances.
Drill, countersink, countersink and dimple holes precisely for solid rivets and blind fasteners using drill presses, rivet guns, pneumatic tools and fixtures; verify hole quality and edge distances to engineering standards.
Install and set solid rivets (tangential and driven), universal head and AN-type rivets using bucking bars, pneumatic rivet guns, and handheld rivet tools while following torque and pull specifications for structural joints.
Perform nutplate installation, machine screw and flush fastener installation, including machining, deburring, reaming and installation of self-locking hardware to OEM and regulatory standards.
Perform structural sheet metal repairs, edge reinforcement, and patching including developing and fitting repair doublers, backing plates and splice plates under senior technician guidance.
Prepare and finish sheet metal surfaces: deburring, edge rolling, fluting, sanding, sealing and priming using approved materials and processes to prevent stress concentrators and corrosion on jet airframes.
Use basic CAD/CAM/FAIR documentation tools and read fabrications drawings; transfer simple patterns from drawings to workpieces and assist in nesting parts for efficient material use.
Assist in layout and fabrication of complex assemblies such as wing leading edges, fuselage panels, door frames and cargo handling structures, under supervision, ensuring proper riveting patterns and structural alignment.
Follow engineering change notices (ECNs), service bulletins (SBs), airworthiness directives (ADs) and work orders precisely; document completed work in maintenance tracking systems and ensure traceability of parts and fasteners.
Support non-destructive testing (NDT) activities (visual inspection, dye penetrant, borescope) by preparing parts, cleaning surfaces and documenting inspection findings under direction of certified NDT personnel.
Use hand and power deburring tools, files and grinders to remove burrs and sharp edges while preserving structural integrity and maintaining specified edge breaks and radii.
Maintain tooling and fixture sets: clean, inspect, and report wear on brakes, shears, bucking bars, drill bits and jigs; perform basic maintenance and request replacement tooling to keep production quality high.
Follow aerospace safety and hazardous material procedures, including COSHH/OSHA-compliant handling of primers, solvents and sealants, and adhere to personal protective equipment (PPE) and shop safety protocols at all times.
Assist with removal and reinstallation of structural components during scheduled maintenance, inspections and modifications, ensuring proper torque, fit and sealant application upon reassembly.
Measure and report material thickness, tolerances and part conformity; identify non-conforming parts and escalate to quality or engineering for disposition to maintain airworthiness.
Keep accurate fabrication and repair records, rivet counts, serial numbers and material lot traceability in maintenance logs, traveler cards and electronic maintenance systems per regulatory requirements.
Participate in continuous improvement and lean manufacturing activities by suggesting process improvements, waste reduction measures and time-saving shop practices to improve throughput and quality.
Shadow and learn from senior technicians to master advanced skills such as cold-working, flare forming, rivet backing, trim-and-fair operations and complex assembly techniques specific to jet aircraft structures.
Assist with component kitting, inventory control and material requisition for scheduled jobs to ensure materials and fasteners are available and compliant for planned structural tasks.

Secondary Functions

Maintain a clean, organized, and safety-compliant work area; perform 5S/lean housekeeping tasks to support efficient aircraft structural workflows.
Track and manage shop inventory for sheet metal stock, fasteners and consumables; assist purchasing with reorder levels and material certification documentation.
Support quality assurance by preparing items for inspection, tagging completed parts and assisting with QA corrective actions and root-cause analysis under supervision.
Participate in on-the-job training, formal apprenticeship classes, and certification exams; document training progress and competency checks.
Assist engineering and production teams with simple pattern development, material usage calculations and cost-saving recommendations when requested.
Help prepare aircraft surfaces for paint or corrosion control processes by removing contaminants, applying primers and masking parts according to paint shop guidelines.
Aid in the handling and movement of large components and assemblies using appropriate material handling equipment (hoists, cranes, trolleys) following shop rigging protocols.
Support ad hoc technical projects such as tooling trials, prototyping of brackets or supports, and small modifications to production jigs under engineering supervision.
Participate in safety stand-downs, toolbox talks and compliance audits; report hazards and support corrective actions to maintain a safe shop environment.
Provide assistance to other trades (composites, hydraulics, wiring) as required for integrated maintenance events, coordinating with senior techs to ensure structural interfaces are preserved.
