Implementation of fatigue prediction models, such as the Sleep, Activity, Fatigue, and Task Effectiveness model, optimize scheduling by being able to predict pilot fatigue at any point in time. Although the mathematical model is limited by individual pilot differences it is the most accurate existing prediction because it takes into account ...
AIA Flight 808 was the first aviation accident where pilot fatigue was cited as a probable cause. [4] The NTSB issued a recommendation to the Federal Aviation Administration to review and update regulations on crew scheduling and duty time limits to incorporate the latest research into the effects of fatigue.

Studies like Project Horizon [26] have recently been done to analyse which factors cause this fatigue. The lack of sleep and quality of the sleep are two of the main issues. The lack of sleep is due to the long hours that the workers (especially the officers) have to do (work weeks of 70 hours +). [27]
The aircraft experienced a loss of control due to a malfunction of the left engine propeller control unit, which was attributed to a design flaw. March 3, 1991 25 1 0 United Airlines Flight 585: Colorado Springs: Colorado: Boeing 737-200: The aircraft experienced a loss of control during approach due to a rudder hardover caused by a design flaw.
The US Code of Federal Regulations defines an accident as "an occurrence associated with the operation of an aircraft, which takes place between the time any person boards the aircraft with the intention of flight and all such persons have disembarked, and in which any person suffers death or serious injury, or in which the aircraft receives substantial damage;" an incident as "an occurrence ...
the captain's performance deficiencies, likely due to factors including, but not limited to, fatigue, distraction, or confusion, consistent with performance deficiencies exhibited during training; the first officer's fatigue due to acute sleep loss resulting from her ineffective off-duty time management [7] [1] [22] [23]
Families of the accident victims lobbied the U.S. Congress to enact more stringent regulations for regional carriers and to improve the scrutiny of safe operating procedures and the working conditions of pilots. The Airline Safety and Federal Aviation Administration Extension Act of 2010 (Public Law 111–216) required some of these regulation ...
The report concluded that "the probable causes of the accident were the flight crew's mismanagement of the aircraft's speed, altitude, headings, and attitude through inconsistent flight control inputs resulting in a loss of control and their failure to abide by CRM (Crew Resource Management) principles of mutual support and calling deviations".
