The U.S. Department of Transportation's Federal Aviation Administration (FAA) issued Advisory Circular (AC) 120-115 on December 2, 2016, to provide information on Maintainer Fatigue Risk Management. The AC describes the basic concepts of human fatigue, its relation to safety in aviation maintenance, and provides guidance on Fatigue Risk Management (FRM) methods and benefits. It also identifies methods for integrating FRM within a Safety Management System (SMS) and lists related reading materials. The document highlights the importance of managing human fatigue risk in the aviation maintenance industry, citing statistics such as maintenance personnel getting 3 hours less sleep per night than recommended, and the estimated $136 billion in lost productivity due to human fatigue in the U.S. each year. The AC discusses the causes of human fatigue, fatigue hazards, and safety and health risks, including impaired judgment, decreased attention span, and increased risk-taking. It also provides information on duty-time limitations and the importance of managing fatigue risks to ensure the safety of the flying public and maintenance personnel.
