Program SUMMARY NASA has initiated a research program with the long-term objective of supporting the aerospace industry in addressing issues related to the aging commercial transport fleet. The interdisciplinary program combines advanced fatigue crack growth prediction methodology with innovative nondestructive examination technology with the focus on multi-site damage (MSD) at riveted connections. A fracture mechanics evaluation of the concept of pressure proof testing the fuselage to screen

All long-term program elements have been initiated and the plans for the methodology verification program are being coordinated with the airframe manufacturers. 20, Security Classif (of this page) Unclassified 21 No. of pages ]9 22.
