Fan Blade Out
Blade off testing or blade out testing is a specific form of Air safety#Engine failure, air safety testing required by the Federal Aviation Administration and other safety agencies to certify safety performance of jet engines. The tests require engine manufacturers to carry out at least two tests of the engine, to make sure that the engine can survive a Jet engine#Compressor blade containment, compressor or fan blade breaking off within the engine and a turbine blade breaking off within the engine, without fragments being thrown through the outside enclosure of the engine, creating an uncontained engine failure. In the United States, the tests are required by Title 14, Part 33 Subpart F, Section 33.94 of the US Code of Federal Regulations (CFR), ''Blade containment and rotor unbalance tests''. Equivalent test requirements are provided in the Certification Specifications for Engines (CS-E), published by the European Aviation Safety Agency (EASA). Design One of the most challenging ...

Air Safety
Aviation safety is the study and practice of managing risks in aviation. This includes preventing aviation accidents and incidents through research, educating air travel personnel, passengers and the general public, as well as the design of aircraft and aviation infrastructure. The aviation industry is subject to significant regulation and oversight. Aviation security is focused on protecting air travelers, aircraft and infrastructure from intentional harm or disruption, rather than unintentional mishaps. Statistics Evolution In 1926 and 1927, there were a total of 24 fatal commercial airline crashes, a further 16 in 1928, and 51 in 1929 (killing 61 people), which remains the worst year on record at an accident rate of about 1 for every flown. Based on the current numbers flying, this would equate to 7,000 fatal incidents per year. For the ten-year period 2002 to 2011, 0.6 fatal accidents happened per one million flights globally, 0.4 per million hours flown, 22.0 fatali ...
