What International School of Aerospace NDT Ltd does

International School of Aerospace NDT Ltd (ISA NDT), trading as ISA, is a Norwich, UK-headquartered private limited company founded in 1996 that delivers non-destructive testing (NDT) training, examination, and certification services exclusively to the global aerospace industry. The company provides structured instruction across all major aerospace NDT methods — penetrant, magnetic particle, eddy current (including phase analysis), ultrasonic (including phased array), radiographic (including X-Ray 3D CT and non-film), infrared thermographic, and specialised courses such as aircraft wheel inspection, bond testing, radiographic film interpretation, and etch inspection — at Levels I, II, and III under SNT-TC-1A, NAS 410, BS EN 4179, ASNT-CP-189, ISO 9712, PCN, and BSS 7600 standards.

Training is delivered at a purpose-built facility at Norwich International Airport (Unit A & B, Iceni Court, Delft Way, Norwich, NR6 6BB) featuring a 200kV Radiographic and Isotope Exposure Room, automated film processing, and laboratories equipped with OEM-standard NDT instrumentation; each course is split 50% classroom theory and 50% hands-on practical application. In addition to residential Norwich-based courses, ISA dispatches instructors worldwide to deliver on-site training and approval examinations at customer premises, a capability underpinned by BINDT Outside Agency Approvals and British Council Accreditation.

Revenue is generated from one-time course fees (£700 to £2,800 per course), per-method approval examination fees (£380 Level I/II, £550 Level III per method, £380 Level III Basic), daily recertification/refresher rates (£245/day), and ancillary Level III consultancy, internal audits, NDT procedure writing/approval, equipment search, and job-search assistance. The go-to-market is enterprise field sales combined with direct website bookings and social-media presence (Facebook, Twitter/X, Instagram), targeting two primary verticals: commercial aerospace (manufacturers, engine OEMs, operators, MRO/inspection firms) and global air forces/defence, with customers drawn from more than 70 countries.
