Inspecting fan blades or any engine components using a full suite of FAA-approved, NDT inspection capabilities to reduce aircraft downtime.
Engine Inspection Experts
For CFM56-7B engines specifically, CFM Service Bulletin (SB) CFM56-7B S/B 72-1033 requires a repetitive fan blade dovetail ultrasonic inspection, utilizing a special ultrasonic non-destructive test (NDT) kit. Only General Electric (GE) factory-trained NDT technicians may perform this testing. AerSale® has complied with GE’s mandatory training, obtained the necessary ultrasonic NDT kit, and is fully authorized and ready to conduct these tests.
Engine Inspection Testing
Our National Aerospace Standard (NAS) 410 level III and level II skilled technicians utilize only new, properly calibrated equipment that is state-of-the-art technology. Tests include:
- Eddy Current (surface, subsurface, rotary hole, conductivity, coating thickness)
This technique is extremely sensitive and the most common and effective method for detecting tight, subsurface cracks in fan blades.
- Ultrasonic (metal, composite laminate, carbon, material thickness)
Ultrasonic testing uses high-frequency sound waves to detect flaws, measure thickness, and evaluate material properties. It creates a picture of the material in a process much like sonar.
- Bond Testing (metal to metal, metal to composite, composite to composite, and other plastics)
Bond testing is a highly portable, cost-effective means of validating structural integrity of many aircraft materials.
- Magnetic Particle
This process detects surface and shallow subsurface discontinuities in ferromagnetic materials using magnetic fields and particles.
- Penetrant Inspection (small and large quantities and components)
Fluorescent liquid penetrant is an excellent method for detecting surface cracks that react to fluorescent light.
- Resonance Testing (coin-tapping, woodpecker)
A simple method of detecting broken bonds (disbonds) within composite material is the “coin tap,” where the material is gently struck with a metal object and the inspector listens for the signature dull thud of a defect.
- Thermal Imaging (water intrusion detection with thermal blankets and a FLIR 400 camera)
Heat transfer through an object can be indicative of disbonds or water entrapment. A thermal camera can detect minute changes in temperature and enhance the display to pinpoint a problem.
In-House and On-Site Engine Inspection Capabilities
We can accept and process parts for NDT at our facilities or bring testing equipment to yours. Although crack discovery can ground an aircraft, our testing regimen will get you back into revenue service sooner while ensuring the safety of the flying public.
Regenerate, Repair, or Replace
As a vertically integrated maintenance, repair, and overhaul (MRO), AerSale has many options for your fleet’s engine requirements. As the single most expensive component on your aircraft, you need flexible engine options. We provide a full array of choices for spare engine coverage including aircraft engines for sale, lease, and exchange, as well as engine parts.
