Course duration: 2 Days 

All EFC courses comply with SAE-CACRC, FAA, CAA and EASA standards.

This is a Training 'level 1-2 composite NDI Tap testing course. It is a "Basic" (NDI) composite parts Tap testing  course designed to meet the requirements of a wide range of participants such as; Technicians, Certifying staff, NDI Inspectors and Quality control Inspectors, who want to have a better understanding and importance and limitations of tap testing on advanced composite parts with thin skins .

Advised Pre-requisites;

  • Preferably some basic knowledge of what composites are and made out and used for.
  • Normal hearing in both ears.
    Checking your hearing quality is an important step if you professionally want to perform Tap testing composite parts in your company.

Personnel of technical departments with prior experience in Composites and who want to gain a better understanding of inspecting parts made out of advanced composite materials by mean of hand Tap testing,
electronic Tap hammer testing for de-laminations or dis-bonds 
Personnel with some composite fabrication or Repair experience

Number of participants: Minimum required 4 and Maximum 12 per course*.
* Courses will be confirmed as running by EFC as soon as sufficient applications are received! 

To provide participants with theoretical knowledge and practical Hands-On skills necessary to carry out basics off  composite damage mapping, allowable  damage limit findings and tap testing with various tapping devices/tap hammers.

At the end of the course the participants:

  • Must be attentive to details in composite parts
