| Experimental mechanic | Occupations | 1: Lays out, fabricates, and assembles developmental or experimental structural and mechanical parts and assemblies, and installs parts and assemblies in prototype aircraft or spacecraft, following engineering information, using precision instruments, handtools, power tools, and shop equipment: Reads and interprets blueprints, sketches, loft information, and related engineering data to plan sequence of operations and methods for fabricating, assembling, and installing parts and assemblies. Lays out radii, angle, and dimensions of parts on assorted materials, using precision measuring and marking instruments, such as gauges, calipers, scale, and scriber, applying trigonometric calculations to solve layout problems. Sets up and operates shop equipment, such as bandsaw, lathe, table saw, drill press, shear, and brake, to shape and form parts. Verifies dimensions of parts, using precision measuring instruments. Drills, countersinks, and reams holes in parts and assemblies for bolts, rivets, and other fasteners, using power tools. Aligns and joins structural assemblies, using transit, sight level, handtools, power tools, clamps, and fasteners. Installs experimental parts and assemblies in prototype structure to verify accuracy of layout and assembly. Tests functional performance of installed parts. Confers with engineers to resolve fabrication and installation problems. May fabricate or modify tooling, such as jigs, fixtures, templates, and form blocks. May fabricate and assemble reduced-scale mockups of parts and assemblies. May be designated by type of part or assembly developed as Controls Development Mechanic (aircraft mfg.); Developer-Prover, Mechanical (aircraft mfg.); Fabrication And Structures Development Mechanic (aircraft mfg.); Hydraulic And Plumbing Development Mechanic (aircraft mfg.); Mechanic, Experimental Structural Assembly (aircraft mfg.).

| 2: Sets up and operates variety of machines to fabricate experimental motorcycles or components to meet operating and endurance standards required by blueprints, sketches, or oral instructions: Assembles motorcycle or components, using handtools. Positions and clamps motorcycle on test rack. Attaches test equipment, such as tachometers, thermocouples, pressure and strain gauges, flow and velocity meters, to motorcycles, using handtools. Operates motorcycle at specified speeds and loads, and records meter and instrument readings on test records form. Disassembles motorcycle and analyzes cause of defect in components, such as exhaust system, frame, hydraulic fork, spring, or wheels, using handtools or power tools, calipers, micrometers, gauges, and other measuring instruments. Operates drill press, engine lathe, milling machine, or other machines to fabricate experimental motorcycle parts for testing, and secures test equipment to motorcycle, using jigs & fixtures. Test rides motorcycle to verify performance and durability of motorcycle components. Compiles and submits report to engineering department to show results of tests and recommendations for design or material changes. (references) | |||
