NDT - Level III

Position Overview

Technical authority for ultrasonic NDT of aerospace composite structures. Defines and validates inspection methods, ensures traceable results, and advises engineering on defect severity.

Key Responsibilities:

• Write, review and approve the written NDT procedures and instructions that Level II personnel execute, as required of Level III by EN 4179 / NAS 410. These cover equipment setup, calibration on reference blocks, scanning parameters, and the recording and rejection levels (for example, signal amplitude thresholds relative to the reference standard) used to identify defects, derived from the applicable engineering specifications and acceptance criteria.
• Evaluate and interpret inspection results (A/B/C-scan) against engineering specifications and acceptance criteria. Review the work of Level I/II inspectors and resolve doubtful or non-conclusive indications.
• Define equipment configuration and calibration processes for PE (Pulse-Echo), TT (Through-Transmission) and PEAUT (automated pulse-echo) systems, including periodic verification and calibration acceptance criteria.
• Define reporting standards that ensure full defect traceability (part ID, procedure revision, equipment and calibration records, defect maps with coordinates and sizing) for downstream engineering collaboration.
• Define reference blocks for the different part types (monolithic laminates, sandwich/honeycomb, tapered areas, radii, joints), including artificial defects and manufacturing controls.
• Advise engineering on defect severity (size, depth, location, criticality), communicating technique limitations and uncertainty to support disposition decisions.

Qualifications
