Use of Nondestructive Testing in the Evaluation of Airport Pavements
Focuses on nondestructive testing (NDT) equipment that measures pavement surface deflections after applying a static or dynamic load to the pavement. It also briefly introduces other types of nondestructive measuring equipment to illustrate how supplementing NDT data with other test data may improve the quality and reliability of the pavement evaluation. This version updates Chapter 8, NDT-Based Evaluation and Design Updates, to reflect the requirements of the pavement design program FAARFIELD rather than the previous design program LEDFAA.

Fatigue Management Programs for In-Service Issues
a.This advisory circular (AC) provides guidance on developing and implementing a Fatigue Management Program (FMP) to address in-service issues for metallic fatigue critical structure. An applicant may develop an FMP as one method to address an unsafe condition when the Federal Aviation Administration (FAA) determines an airplane type design has a demonstrated risk of catastrophic failure due to fatigue. In such cases, the FMP should incorporate damage-tolerance based inspections or a part replacement/modification program to mitigate the demonstrated risk. The FMP should also incorporate other fatigue critical structure inspections to address the broader risk posed by potential cracking of these structures in the airplane. The FAA will mandate the FMP by Airworthiness Directive (AD). The FAA may also approve the FMP as an alternative method of compliance (AMOC) to an AD.
b.This AC includes guidance relevant to developing FMPs for other purposes such as life extensions, type certification requirements, or non-mandatory maintenance programs. This guidance supplements other ACs that contain guidance for developing damage-tolerance based inspection programs to look proactively for potential cracks. Such guidance includes AC 91?56B, Continuing Structural Integrity Program for Airplanes, AC 25.571?1D, Damage Tolerance and Fatigue Evaluation of Structure, and AC 23?13A, Fatigue, Fail-Safe, and Damage-Tolerance Evaluation of Metallic Structure for Normal, Utility, Acrobatic, and Commuter Category Airplanes. Applicants should use product specific guidance in conjunction with this AC.
