NDT that Supports your Bottom Line

Aerospace Manufacturing and Maintenance

We provide accurate, fast and affordable resonance inspection to eliminate field failures, improve process control and monitor life for in-service parts.  

Process Compensated Resonance Testing (PCRT) is an NDT solution that enables aerospace OEMs and MRO providers to detect outlier components and structural defects that affect performance, reliability and safety of flight. PCRT offers process monitoring and control capabilities to prevent quality escapes altogether. For in-service parts, PCRT Life Monitoring can assess the condition of parts throughout their service life to maximize their value. These benefits, along with PCRT’s high testing throughput and affordability, provide real benefits to aerospace companies’ bottom lines.  

PCRT can be applied to a diverse array of critical aerospace components, from simple ball bearings to complex turbine airfoils. PCRT can be applied to metals, ceramics and composite, and it can monitor the fabrication processes for those materials.

A list of applications for PCRT in aerospace includes, but is not limited to:

Aircraft Engines

  • Turbine blades and disks
  • Hybrid bearing ceramic rolling elements
  • Fuel nozzles
  • Static components (shrouds, endwalls)
  • Impellers
  • Radial turbines
  • Shafts

Landing gear

  • Wheels
  • Carbon brake disks
  • Torque tubes
  • Structural and kinematic components (pistons, sleeves, trunions)
  • HVOF-coated components
  • Fasteners

Airframe components

  • Fasteners
  • Control system mechanisms (gears, linkages)
  • Structural components

Advanced materials

  • Equiax, directionally-solidified and single crystal superalloys
  • Ceramics
  • Composites


  • Casting
  • Forging
  • Welding
  • Additive manufacturing
  • Induction Hardening
  • Hot isostatic pressing (HIP)
  • Composite fabrication processes
  • Ceramic matrix composite (CMC) fabrication processes
