Aircraft Mechanic III NDI

Aircraft Mechanic III (23023) Non-Destructive Inspection Technician (NDI): Identifies, locates, and measures hidden and subsurface flaws, corrosion, and separation in bonded and honeycomb structures; the integrity of welds; precision dimensional and volume measurements; and the hardness of materials. Test indications may be represented by cathode ray tube (CRT), visual presentation, digital readout, caliper readout, printout, alarm system, or a combination. Interprets test indications and makes final determination of product as serviceable, repairable, or condemned. On repairable products, records test results, marks defect areas/dimensions on surface of product or work control documents, as appropriate, to specify needed repair processes and/or modifications. Sets up and operates equipment and makes initial instrument settings following guidelines. By use of a test standard with known properties, calibrates instrument for optimum signal pattern. Uses appropriate type of ultrasonic or eddy current instrument and search unit to detect and interpret the relevancy of surface and subsurface flaws in parts. Manipulates transducer or probe over surface of item, simultaneously watching test equipment output for defect indicators. Uses laser optical equipment and software to determine aircraft alignment. Notifies Quality Control, Engineering, or supervisor of abnormal defects for which no repair/inspection instructions are available or when parts failure was contributed to by faulty design
