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 ...
On April 5, 2011, the FAA issued an emergency airworthiness directive (AD) requiring operators of 737 series 300, 400 and 500 aircraft to increase the frequency of inspections of lap joints on high flight cycle airframes. The AD requires that aircraft with over 30,000 cycles be inspected within 20 days of receipt of the AD, or upon reaching ...
The National Transportation Safety Board (NTSB) determines that the probable cause of this accident was a low-cycle fatigue crack in the dovetail of fan blade No. 13, which resulted in the fan blade separating in flight and impacting the engine fan case at a location that was critical to the structural integrity and performance of the fan cowl ...
The list of aircraft accidents and incidents caused by structural failures summarizes notable accidents and incidents such as the 1933 United Airlines Chesterton Crash due to a bombing and a 1964 B-52 test that landed after the vertical stabilizer broke off. Loss of structural integrity during flight can be caused by:
When this accident occurred the number of fatalities made it Australia's third worst civil aviation accident, a status it retains to this day. [6] Two civil aviation accidents caused 29 fatalities each – the 1950 Australian National Airways Douglas DC-4 crash and the 1960 Trans Australia Airlines Flight 538 .

An aviation incident is any operating event that compromises safety but does not progress to an aviation accident. Preventing accidents and incidents is the main goal of aviation safety. One of the earliest recorded aviation accidents occurred on 10th May 1785, when a hot air balloon crashed in the town of Tullamore, County Offaly, Ireland.
The exact cause of the accident was never determined. Northwest Orient Airlines Flight 293 was a Military Air Transport Service charter flight carrying 101 servicemen and their families that crashed into the sea off the Alaska coast on June 3, 1963. The cause of the accident was never determined, and no bodies were ever recovered. [9]
