The Mid-Level Air Ducting Assembly Technician is responsible for the fabrication, installation, inspection, and testing of air ducting and ventilation system components used in aircraft Environmental Control Systems (ECS). This technician works with both metallic and composite ducting, performs routing and sealing tasks, and ensures assemblies meet aerospace specifications. The role supports both production and retrofit programs and may involve troubleshooting and rework of installed systems.
Assemble and install rigid and flexible air ducts for aircraft cabin and avionics ventilation systems
Read and interpret engineering drawings, work orders, and manufacturing process instructions (MPIs)
Prepare ducts and fittings by cutting, flaring, beading, swaging, and bonding as required
Install clamps, couplings, brackets, and insulation in accordance with aerospace standards
Seal and torque connections using aerospace-grade adhesives, sealants, and tools
Conduct fit checks and alignment of duct runs in test jigs or airframes
Identify and correct misalignments or nonconformities; escalate complex issues to supervisors or engineering
Inspect completed assemblies for leaks, structural integrity, and FOD compliance
Document work using digital systems or paper travelers and ensure proper traceability of parts and materials
Follow all EHS, 5S, and quality control procedures in cleanroom or production environments
Air duct fabrication and assembly
ECS/ventilation component installation and alignment
Mechanical fitting, sealing, and torqueing
Manufacturing quality and compliance in aerospace production
Education:
High school diploma or GED (required)
Technical certificate or associate degree in Aerospace Manufacturing, Mechanical Technology, or related field (preferred)
Experience:
3–5 years of experience in aircraft ducting, HVAC, or ECS assembly
Familiarity with aircraft manufacturing or MRO environments and aerospace fastener systems
Prior work with metallic (aluminum, titanium) and composite duct materials
Technical Skills:
Ability to read blueprints, 3D models, and aerospace installation drawings
Skilled in using hand tools, pneumatic tools, torque wrenches, and swaging/beading equipment
Understanding of aircraft standards (e.g., BAC, AS, or MIL specs) for ducting and ventilation installations
Basic knowledge of leak testing and FOD prevention practices
Soft Skills:
Strong attention to detail and ability to follow exact procedures
Effective communication with cross-functional teams (quality, planning, engineering)
Proactive approach to troubleshooting and quality improvement
Organized, punctual, and safety-conscious
