Scope
This SAE Aerospace Standard (AS) establishes minimum requirements for eddy current inspection of circular holes in nonferrous, metallic, low conductivity (less than 5% IACS) aircraft engine hardware with fasteners removed. The inspection is intended to be performed at maintenance and overhaul facilities on engine run hardware.
Rationale
AS4787A is an extensive revision of this Aerospace Standard resulting from a Five-Year Review and update.

Issuing Committee
AMS K Non Destructive Methods and Processes Committee
The committee of Nondestructive Methods and Processes, AMS Committee K, shall prepare, coordinate, and revise documents related to nondestructive testing technology, such as fluroescent penetrant, magnetic particle, X-ray, ultrasonic, and eddy current, through the participation of manufacturer's suppliers, users, and interested government agencies. Committee activities shall provide a forum for the cooperative interchange of ideas and experience of the participants, resulting in the publication of specifications that embody sound, established aerospace industry practices, and requirements to serve the suppliers and customers of aerospace materials.
