Aerospace NDT

Aerospace NDT Overview

Liquid penetrant specifications, such as ASTM E-1417 and AMS-2647, are considered industry standards for in-process, final, and maintenance (in-service) penetrant examinations for the final acceptance of aerospace products. These widely used specifications state that only materials listed and approved to QPL-AMS-2644 shall be utilized for penetrant examination.  QPL-AMS-2644 refers to the Qualified Products List for aerospace penetrant inspection material.

Certified Materials for Penetrant Inspection

In order to be approved for use on the Qualified Products list, Type 1 fluorescent penetrant systems undergo testing by The United States Air Force Materials Command (USAFMC) at Wright-Patterson Air Force Base in the Air Force Materials Research Laboratory (AFRL). Only materials specifically stating “certified to AMS 2644” are approved for use.  Manufacturers who list only “meets the requirements of AMS 2644” have not certified their products for approval.

Materials listed on the QPL meet the following rigorous requirements:

• NADCAP quality programs
• FAA and EASA repair stations
• AS9100 and ISO 9001:2015 quality systems
• OEM aerospace manufacturers: Airbus, Boeing, General Electric, Gulfstream, Honeywell, Hamilton Sundstrand, Pratt & Whitney, Parker Hannifin, Rolls-Royce.
