Eddy Current Array (ECA) — Fastener-Hole Inspection Decoded

ECA per ASME V Article 26, aerospace fastener-hole inspection, aging-aircraft lap-joint corrosion. ASNT NDT Level III + Atlantis NDT expert authored. Refining, petrochem, marine, aerospace, power, mining, LNG, offshore wind, hydrogen, CCS — global delivery.

Method Foundation

ECA per ASME V Article 26, aerospace fastener-hole inspection, aging-aircraft lap-joint corrosion. Physics-grounded, code-aligned, ASNT NDT Level III led.

Equipment + Calibration

Instrument selection, reference standards, calibration cadence per the relevant ASTM/ISO/ASME standard.

Acceptance Criteria

Defect classification + sizing + acceptance limits per construction + in-service codes. Free Atlantis NDT consultation.

Atlantis NDT Stack

Atlantis NDT ERP + Atlantis Digital Twin platform + NDT reporting software integrated for this method. Audit-ready bundle. Free demo.

Construction-Code + In-Service-Code Crosswalk

Identify the governing product, construction or in-service requirements and their adopted editions. Record which examination and acceptance references they invoke; do not assume that standards from different applications are interchangeable.

Mandatory vs Non-Mandatory Appendices

Check the status of annexes, appendices and referenced documents in the applicable edition. Resolve proposed departures through the authority responsible for the work; the route depends on the governing requirements.

Inspector Qualification + Method Authorisation

Confirm the personnel qualification and authorisation requirements invoked for this work. Record who performs the examination, who reviews the results and who has authority to decide disposition. These responsibilities are not identical in every scheme.

Acceptance Criteria + Defect Disposition Decision Tree

Describe each indication using the characteristics required by the examination procedure. Apply the specified acceptance rules within the authorised scope and refer unresolved findings to the responsible technical authority.

Common Audit Findings + Atlantis NDT Procedure Pack

For the review, retain the applicable procedure revision, personnel authorisation, equipment checks, location references and examination results. Ask the customer which additional evidence and approvals the contract requires.

Damage Mechanisms (API 571 Cross-Reference)

API RP 571 enumerates damage mechanisms in refining + petrochem service. For aerospace, the dominant mechanisms include: sulfidation (API 571 §4.4.2), naphthenic-acid corrosion (§4.4.6), high-temp H2 attack / HTHA (§4.5.1), amine-stress corrosion (§4.5.4), sour-water cracking (§5.1.3), CUI / corrosion-under-insulation (§4.3.4), MIC / microbiologically-influenced corrosion (§4.3.8), erosion-corrosion (§4.2.14), and chloride stress corrosion of austenitic SS (§4.5.1.4). Atlantis NDT Level III consulting (consult here) maps each circuit to its dominant mechanism + recommends method.

RBI per API 581 — Risk-Driver Decomposition

RBI per API RP 581 decomposes consequence + likelihood for aerospace equipment: (1) Generic Failure Frequency (gff) by component class; (2) Damage Factor (DF) per active mechanism; (3) Inspection Effectiveness Factor (A-E) based on prior inspection thoroughness; (4) Consequence — Financial + Safety + Environmental.Atlantis ERP for live data.

FFS per API 579 — When + Why

Where findings require engineering assessment, the responsible integrity team must define the assessment scope, necessary measurements and applicable methodology. Atlantis NDT can discuss examination evidence; it does not provide an engineering fitness-for-service assessment.

Atlantis NDT Stack Configuration for aerospace

Atlantis NDT delivers integrated stack for aerospace operators: Atlantis ERP (NDT reports, technician certificates, crew dispatch and equipment calibration), Digital Twin platform (3D asset model with overlaid damage-mechanism heat-map), Reporting Software (offline mobile capture with code-aligned templates), and Atlantis NDT LMS (continuous inspector cert refresh per aerospace-specific scope). Affordable, accessible, fully customizable.

Frequently Asked Questions

Q1: How does Atlantis differ from in-house teams?

A: Atlantis NDT delivers ASNT Level III bench depth + global cert roster + integrated software stack (ERP + DT + Reporting + LMS) — replaces 4-8 disjoint tools + spreadsheets. Inspection-native, not generic CMMS bolt-on.

Q2: How does this fit our vertical operational model?

A: Atlantis NDT delivers vertical-specific procedure packs + inspector cert rosters + asset-integrity playbooks. Free 30-min discovery call scopes your specific asset class + damage mechanisms + code requirements + delivery model preference.

Q3: How does AI-assisted defect detection get code acceptance?

Automation needs a documented scope, representative performance evidence and an agreed review process. Confirm whether the governing examination requirements permit the proposed technique. A software feature or general risk-planning standard does not establish code acceptance.

Q4: What is the typical implementation timeline?

Implementation time depends on the agreed configuration, data preparation, interfaces and acceptance tests. Confirm milestones and responsibilities in the proposal.

Q5: Does Atlantis NDT publish pricing?

Pricing depends on region, scope, delivery arrangements and team size. Request a proposal that identifies what is included, what needs configuration and the support provided.

Q6: How does Atlantis integrate with our existing stack?

A: Atlantis ERP has an open REST API, so it connects to SAP, Maximo, NetSuite or any other system that accepts API connections; each integration is scoped with you during implementation. Free integration scoping consultation.

Q7: How do I start?

A: Request a free 30-min consultation at /contact. We reply within one business day. We scope your asset class + damage mechanisms + code requirements + delivery model preference + integration needs in a single call.

Running this as a programme, not a one-off

If you are responsible for an inspection programme rather than a single job, the recurring problem is rarely the code — it is keeping measured thickness, damage-mechanism assignment and next-inspection dates in one defensible place. Asset integrity management software covers keeping measured thickness readings per CML in one place, so the RBI (API 580/581) and fitness-for-service (API 579) work your integrity team or its specialists carry out starts from measured data rather than default rates. Atlantis supplies the NDT data and the software to hold it; it does not perform RBI or FFS assessments.
