This National Guard position is for a SHEET METAL MECHANIC (AIRCRAFT), Position Description Number
D1371000and is part of the MS 186 ARW, National Guard.

Duties

As a SHEET METAL MECHANIC (AIRCRAFT), WG , you will accomplish the inspection, repair, modification, installation and troubleshooting of sheet metal, fiberglass, bonded honeycomb and other structural materials and components as well as treatment (i.e., mechanical and chemical), and painting of missiles, aircraft powered and nonpowered Aerospace Ground Equipment (AGE), and monitoring aircraft and equipment washing.

(1) Independently inspects aircraft and determines the nature and extent of repairs to be made, using applicable technical orders as guidelines. Works directly on the aircraft and its components, fulfilling such tasks as removal, repair, modification and installation of parts and assemblies, such as frames, stringers, longerons, bulkheads, beams, ribs, spars, skin, cowling, brackets, faring, access doors, panels and other related items. May be required to clear red "X" conditions.

(2) Repairs cracks in aircraft skin. Fabricates and fits patches to damaged areas, determining repair detail necessary to retain or restore original strength. Fits and trims components to aircraft such as landing gear doors, control surfaces, flaps access doors and other assemblies. Seals structures to make them pressure, water and

weather tight.

(3) Troubleshoots aircraft structural repair situations in such areas as fuselage, tails, wings, cowlings, and stabilizers. Removes, forms, fits, and installs highly stressed and double contoured skins, using hand or powered drilling and cutting tools and other metal working equipment. Determines shear and bearing load factors during rivet replacement. Installs heads up, regular, heat treated, high shear, and blind type aircraft rivets and fasteners, using pneumatic riveters, special tools and bucking bars. Removes damaged or broken fasteners and receptacles.

(4) Aligns and balances component structures and airframe using precision measuring instruments and levels. Performs metal-to-metal bonding where delamination of surfaces and core material occurs in control surfaces.

Repairs or replaces retaining frames and installs plastic laminated blanks. Designs and constructs forming fixtures.

(6) Manufactures and ensures that metal tubing, conduits and cables are fabricated and tested in accordance with drawings and specifications. Fabricates and repairs flexible control cables.

(7) Performs fabrication of local manufactured items requited for aircraft and equipment. Work includes layout, bending, cutting, forming and assembling. Devise and calculates patterns employing the principles of triangulation, radial and parallel line development.

(8) Sets up and operates power shears, brakes, rolls, dimpling machines, drill presses, saws, portable powered tools, specific detection and measuring equipment, and other metal working equipment, including use of other tools of the trade. Requisitions necessary supplies and equipment for the activity.

(9) Prepares and designs layout, dies, jigs, and templatesnecessary to carry out fabrication repair or modification of aircraft,engine, AGE, and other equipment

(10) Identifies metal corrosion. Performs necessary testingto identify type corrosion present by examination.

(11) Removes corrosion by mechanical and chemical proceduresto include use of portable powered (electric and pneumatic) sanders,buffers, brushes, bead blasters, vacuum cleaners, scrapers, grinders,acids, caustics, solvents, alcohols and other agents used in corrosioncontrol processes.

(12) Applies protective coatings, markings, and decals afterproper removal of corrosion and treatment of metals.

(13) Identifies, blends, stores, controls, and disposes ofhazardous materials such as acids, caustics, alcohols, solvents,cleaners, primers and surface coatings used for corrosion removal,treatment and protection in accordance with applicable directives.

(14) Performs other duties as assigned.
