What is magnetic particle inspection?

Magnetic Particle Inspection (MPI) is a non-destructive testing method used to detect surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, and cobalt. The process involves magnetizing the material and then applying ferrous particles over the surface. If there are any cracks or defects, the magnetic field is disrupted, causing the particles to gather at the site of the flaw, making it visible under proper lighting conditions. MPI is widely used in industries like aerospace, automotive, and manufacturing for quality control and safety assurance.

What skills and qualifications are needed to thrive as a magnetic particle inspection technician?

To thrive as a Magnetic Particle Inspection (MPI) Technician, you need a solid understanding of non-destructive testing principles, attention to detail, and typically a certification such as ASNT Level I or II. Familiarity with MPI equipment, UV lights, yokes, and documentation systems is crucial for accurate inspections. Strong observational skills, problem-solving ability, and effective communication help technicians identify defects and report findings clearly. These skills and qualifications are important to ensure the safety, integrity, and compliance of materials and components in industries like aerospace, automotive, and construction.

What are the most common challenges faced by magnetic particle inspection technicians on the job?

MPI technicians often encounter challenges such as interpreting ambiguous indications, working in confined or awkward spaces, and ensuring proper surface preparation to avoid false readings. Adhering to strict safety protocols when handling magnetic fields and chemicals is essential. Additionally, effective communication with other inspectors and engineers is crucial for accurately documenting and reporting findings, which directly impacts the integrity and safety of inspected components.

What is the difference between Magnetic Particle Inspection vs Ultrasonic Testing?

AspectMagnetic Particle InspectionUltrasonic Testing
CredentialsLevel I/II certifications in magnetic particle testingLevel I/II certifications in ultrasonic testing
Work EnvironmentMagnetic fields, surface and near-surface flaw detectionSound wave transmission, internal flaw detection
Industry UsageManufacturing, aerospace, oil & gasManufacturing, aerospace, oil & gas

Both Magnetic Particle Inspection and Ultrasonic Testing are non-destructive testing methods used to detect flaws in materials. Magnetic Particle Inspection is ideal for surface and near-surface flaws in ferromagnetic materials, while Ultrasonic Testing can detect internal flaws in a wider range of materials. The choice depends on the specific inspection needs and material type.

How much does a magnetic particle inspector make?

A magnetic particle inspector typically earns between $40,000 and $70,000 annually, depending on experience, certifications, and location. Skilled inspectors with certifications like ASNT Level II or III may earn higher wages, especially in industrial or aerospace settings.

Is magnetic particle inspection a good career?

Magnetic particle inspection is a specialized nondestructive testing method used to detect surface and near-surface flaws in ferromagnetic materials. It offers steady employment opportunities in industries such as manufacturing, aerospace, and power generation, often requiring certification and knowledge of magnetic fields and inspection tools. The career can be stable and rewarding for those with technical skills and attention to detail.

Job description

About RTCA:

RTCA is a precision aerospace and defense manufacturing group built on decades of hands-on machining expertise, with roots spanning more than 50 years. We support mission-critical commercial and government aerospace programs across North America through four U.S. Centers of Excellence operating as an integrated platform with 150+ CNC machines and a team of 250+ professionals.

Unlike large organizations where roles can be narrow, RTCA offers hands-on ownership and real visibility – you understand how your work supports the team, the operation, and the end customer. Our flat structure allows employees to take initiative, grow their skills, and have their contributions recognized, while still providing the stability, advanced technology, and meaningful work of an established aerospace manufacturer.

At RTCA, we believe in teamwork, excellence, and delivering with pride. One Team! One Mission!

How You’ll Make an Impact:

The Nondestructive Testing Technician performs Magnetic Particle Testing (MT) — also called MPI or Mag Particle inspection — on parts across all RTCA divisions to detect discontinuities and confirm conformance to customer and regulatory specifications. Current Level 1 MT certification (NAS410) is REQUIRED; Level 2 is strongly preferred. This role is key to ensuring part integrity and airworthiness.


What you’ll be doing as a Nondestructive Testing Technician:

  • Working a full-time onsite position at our Chatsworth, CA location.
  • Perform MT (MPI) inspections on raw materials, in-process, and finished parts per applicable specifications and procedures. Level 1 MT certification is required; Level 2 preferred.
  • Set up, calibrate, and operate MT equipment, including benches, yokes, and demagnetization equipment.
  • Interpret drawings, specifications, and work instructions to apply the correct inspection method and acceptance criteria.
  • Evaluate indications, determine accept/reject status, and document results.
  • Maintain compliance with NAS410, ASTM, AMS, AS9100, and ISO requirements.
  • Document inspection results and nonconformances, and support root cause analysis and corrective actions.
  • Support First Article Inspection (FAI/AS9102), audits, and related quality activities as needed.
  • Follow safety, environmental, and housekeeping requirements in the NDT area.
  • Performs other duties as assigned.

Required Qualifications (Education, skills and experience):

  • Current Level 1 MT (Magnetic Particle) Inspector certification per NAS410 is REQUIRED — a mandatory condition of employment.
  • Experience performing MT inspection in an aerospace, defense, or precision manufacturing environment.
  • Ability to read and interpret engineering drawings and specifications.
  • Working knowledge of AS9100 and/or ISO 9001 quality management systems.
