Details
Document Number: AS4787
Revision Number:
Title
Eddy Current Inspection of Circular Holes in Nonferrous Metallic Aircraft Engine Hardware
Scope
This SAE Aerospace Standard (AS) establishes minimum requirements for eddy current inspection of circular holes in nonferrous, metallic, aircraft engine hardware with fasteners removed. The inspection is intended to be performed at maintenance and overhaul facilities on engine run hardware. This standard has been typically used to inspect for service-induced surface and near surface cracks, but usage is not limited to such applications.
