Gulf Coast NDT service company — outsourced Level III after losing their full-time engineer
A 35-tech NDT service company in the US Gulf Coast lost their full-time Level III with two weeks' notice. We deployed an outsourced ASNT Level III of record (UT/RT/MT/PT/VT) inside seven days, rewrote the Written Practice to SNT-TC-1A 2024, re-issued the 14 procedures against ASME V 2023 and AWS D1.1:2025, ran the next round of Level II re-certifications, and attended the customer audit. Result: zero NCRs, two new customer approvals added (one major refinery, one EPC), continuing on a 24-month retainer.
Middle East fabricator — Aramco 9COM written practice + procedure pack
A Dammam-based pressure vessel fabricator wanted to add UT and RT to its Saudi Aramco 9COM approval scope. We authored the SNT-TC-1A Written Practice (Arabic + English), built the 9COM-compliant UT and RT procedures (including SAES-W-012 weld acceptance), produced the technique sheets and personnel qualification records, and attended the 9COM audit. Result: Aramco 9COM categories 1, 2, 7 approved on first audit; engagement closed inside 11 weeks.
European aerospace MRO — Nadcap NDT (AC7114) program defence after a major finding
A European aerospace MRO received a major finding under Nadcap AC7114 for inadequate Level III oversight on FPI (PT). We performed a 72-hour gap analysis against AC7114, AC7114/4 (PT) and NAS-410 Rev 5, rewrote the PT procedures + Written Practice, retrained and re-qualified the Level II population, and re-presented at the Nadcap re-audit as the Level III of record. Result: finding closed, Nadcap NDT approval retained, continuing as quarterly Level III consultant.

NDT service providers (small to mid-size) — outsourced Level III of record
What is the difference between an in-house Level III and an outsourced ASNT Level III consultant?
An in-house Level III is a full-time employee — typically $180-260K loaded cost in the US, $120-180K in the GCC, and frequently impossible to recruit at all in some markets. An outsourced ASNT Level III consultant (Atlantis NDT model) signs as your responsible Level III for SNT-TC-1A purposes, approves your procedures, signs personnel qualifications, attends audits and answers technical authority calls — without the headcount cost. SNT-TC-1A 2024 explicitly recognises external Level III arrangements provided the responsibility, authority and documentation are clear.

The engagement page for this service

This page describes the service in outline. The full engagement — what the Level III of record signs, how procedure approval and technique qualification are handled, what happens during a client audit, and how the relationship is structured for a company without an in-house Level III — is set out on outsourced ASNT Level III support. Start there if you are scoping an actual engagement rather than researching the category.

An outsourced ASNT Level III of record owns the technical scope that SNT-TC-1A and CP-189 assign to that role — writing and maintaining the written practice, qualifying and approving procedures and techniques, and overseeing personnel qualification — while day-to-day technician supervision and project scheduling stay with the employer. Getting that split clear in the engagement scope is what keeps the arrangement defensible in an audit.

SNT-TC-1A leaves the specifics of a company's qualification and certification program to the employer, but requires a Level III to establish it — which is why the written practice, the document that defines qualification requirements, examination content, and certification criteria for every method and technique used on site, carries the Level III's signature and technical authority. CP-189 formalizes the same role for companies that certify against the standard directly rather than through SNT-TC-1A's recommended-practice framework. An outsourced Level III engagement works the same way a full-time one does on paper — same signature authority, same responsibility for procedure and technique approval. The difference is in cadence and scope: a fractional consulting engagement is structured around defined review cycles and on-call availability rather than daily presence on the shop floor.

What stays with the outsourced Level III versus what stays with the client

The written practice is the anchor document, and it's squarely the Level III's responsibility to write, maintain, and revise it — defining which methods and techniques are used, what qualification path each technician follows (training hours, experience, examination requirements) per SNT-TC-1A guidelines, and how recertification and requalification are handled. Procedure qualification and approval sits with the Level III as well: a new UT technique for a difficult geometry, or a PAUT procedure for a new weld configuration, needs Level III sign-off before it's used for reportable inspection work.

What doesn't transfer to an outsourced Level III is the client's day-to-day operational responsibility — assigning technicians to jobs, managing project schedules, and supervising fieldwork on a given shift stay with the employer's own Level II or project leads. The Level III's oversight of personnel qualification means confirming that the qualification program is being followed correctly, not personally supervising every inspection. That distinction matters in practice: an outsourced Level III engagement replaces the technical authority function, not the operational management structure a company already runs.

Technique approval deserves its own mention because it's the piece most often shortcut in practice: a technician improvising a scan plan for an awkward geometry in the field is a common source of nonconformance in an audit, and it's the Level III's documented approval — not just informal sign-off — that closes that gap.

In-house Level III or outsourced — what actually decides it

Company size is a weak proxy for this decision and gets it wrong in both directions — a mid-size company running one NDT method at one site can justify a full-time Level III if inspection volume is high enough to keep that role busy, while a larger multi-site operation with modest inspection volume per site is often better served by a fractional arrangement than by hiring redundant Level IIIs at each location.

The real drivers are inspection volume, method diversity, and site count. High volume in a narrow method set — say UT and MT on a single fabrication line — can justify a dedicated in-house Level III whose time is fully occupied by procedure development and personnel qualification for that scope. Wide method diversity, with UT, RT, MT, PT, ET, and phased array all in active use, raises the bar for what a single in-house Level III needs to stay current on across every technique, which is where an outsourced arrangement covering the same breadth, or supplementing an in-house Level III's gaps, becomes the more practical structure.

Multi-site coverage is the clearest case for outsourcing: a company running crews across several locations either needs a Level III at each site (rarely justified by volume alone) or travel-heavy coverage from one in-house person, versus a consulting engagement structured for remote procedure review and periodic site visits, which scales across locations without the overhead of relocating technical authority every time a new site opens.

Does an outsourced Level III replace the need for in-house Level II supervisors?

No. The Level III owns procedure approval, written practice maintenance, and qualification oversight; day-to-day field supervision and scheduling remain the responsibility of the employer's own personnel, typically Level IIs or project leads.

What's the difference between SNT-TC-1A and CP-189 for a Level III's role?

SNT-TC-1A is a recommended practice that leaves qualification program specifics to the employer under Level III guidance; CP-189 is a standard companies can certify against directly, with the same core Level III responsibilities for written practice, procedure approval, and qualification oversight.

Can a fractional Level III sign off on new inspection procedures?

Yes. Procedure and technique approval is core to the Level III role regardless of whether the engagement is full-time or outsourced; what changes with a fractional arrangement is the review cadence, not the signature authority.

How many sites can one outsourced Level III engagement reasonably cover?

It depends on method diversity and inspection volume at each site rather than a fixed number — the deciding factor is whether procedure review and qualification oversight can be structured around defined cycles without falling behind actual inspection activity.

Scope the Level III engagement

Define the methods, governing written practice, procedures requiring review, inspection sectors and the person responsible for approval. Separate a document review from responsibility for the entire personnel certification programme. Agree the evidence needed, deliverables and review boundaries before work begins.

Bring the current written practice, relevant procedures, customer specifications and a description of the problem. Use anonymized records for an initial discussion. Request a Level III scope review. For training requirements, see the separate NDT training pathways.
