How many times per month must NDI technicians perform the NDI methods for recertification?

The recertification process for Non-Destructive Inspection (NDI) technicians requires them to perform NDI methods on a bi-monthly basis, which means they must complete these methods two times each month. This frequency ensures that technicians maintain their proficiency and stay current with the NDI techniques and standards that are critical for ensuring the safety and integrity of aviation structures. Regular practice helps to reinforce skills and knowledge, preparing technicians to detect defects accurately and effectively using appropriate inspection methods.
