Noar Linhas Aéreas Flight 4896
On 13 July 2011, Noar Linhas Aéreas Flight 4896, a Let L-410 Turbolet passenger aircraft on a domestic service from Recife to Mossoró, Brazil, crashed shortly after take-off in the Boa Viagem neighbourhood of Recife, after suffering an engine failure. All 16 people on board were killed. Accident The aircraft took off from Recife Airport's runway 18 at 06:50 local time (09:50 UTC) bound for Augusto Severo International Airport, Natal and then Mossoró Airport, its final destination. Seconds after lift-off, the left engine lost power, and a minute later the crew issued a mayday call, requesting to return immediately to the airport. The Turbolet climbed to 400 ft while turning to position itself for a landing on the opposite runway 36, but it subsequently started losing altitude. At 06:54, shortly after the crew announced their intention to attempt an emergency landing on the beach, the aircraft stalled and crashed into an open area of Boa Viagem, between Visconde de Je ...

Engine Failure At Take-off
Engine failure on take-off (EFTO) is a situation, when flying an aircraft, where an engine has failed, or is not delivering sufficient power, at any time between brake release and the wheels leaving the ground / V speeds, V2. The phases of flight are de-lineated to allow simplified standard procedures for different aircraft types to be developed. If an aircraft suffered engine failure on takeoff, the standard procedure for most aircraft would be to abort the takeoff.Peppler, I.L.: ''From The Ground Up'', page 327. Aviation Publishers Co. Limited, Ottawa Ontario, Twenty Seventh Revised Edition, 1996. In small airplanes, if the engine failure occurs before VR (Rotation Speed), the pilot should reduce throttles to idle, deploy speed brakes (if equipped), and brake as necessary. If the engine failure occurs just after liftoff, the pilot must make a decision if there is enough runway to achieve an emergency runway landing, or if an off field landing is required. One of the biggest mis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Landing
An emergency landing is a premature landing made by an aircraft in response to an emergency involving an imminent or ongoing threat to the safety and operation of the aircraft, or involving a sudden need for a passenger or crew on board to terminate the flight (such as a medical emergency). It typically involves a forced diversion to the nearest or most suitable airport or airbase, or an off airport landing or ditching if the flight cannot reach an airfield. Flights under air traffic control will be given priority over all other aircraft operations upon the declaration of the emergency. Types There are several different types of emergency landings for powered aircraft: planned landing or unplanned landing. * ''Forced landing'' – the aircraft is forced to make a landing due to technical problems. Landing as soon as possible is a priority, no matter where, since a major system failure has occurred or is imminent. It is caused by the failure of or damage to vital systems such ...

Aviation Accidents And Incidents In 2011
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes airplane, fixed-wing and helicopter, rotary-wing types, morphable wings, wing-less lifting bodies, as well as aerostat, lighter-than-air craft such as Balloon (aeronautics), hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet aircraft, jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flight Dispatcher
A flight dispatcher (also known as an airline dispatcher or flight operations officer) assists in planning flight paths, taking into account aircraft performance and loading, enroute winds, thunderstorm and turbulence forecasts, airspace restrictions, and airport conditions. Dispatchers also provide a flight following service and advise pilots if conditions change. They usually work in the operations center of the airline. In the United States and Canada, the flight dispatcher shares legal responsibility with the commander of the aircraft (joint responsibility dispatch system). Operational control Dispatchers usually share responsibility for the exercise of operational control, which gives them authority to divert, delay or cancel a flight. Legal requirements known as "Federal Aviation Regulations, 14 CFR part 121" govern dispatch release in the United States. After the release of a flight (in a joint responsibility environment) the dispatcher uses sophisticated software tools to ...

Fluorescent Penetrant Inspection
Fluorescent penetrant inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question. FPI is noted for its low cost and simple process, and is used widely in a variety of industries. Materials There are many types of dye used in penetrant inspections. FPI operations use a dye much more sensitive to smaller flaws than penetrants used in other DPI procedures. This is because of the nature of the fluorescent penetrant that is applied. With its brilliant yellow glow caused by its reaction with ultraviolet radiation, FPI dye sharply contrasts with the dark background. A vivid reference to even minute flaws is easily observed by a skilled inspector. Because of its sensitivity to such small defects, FPI is ideal for most metals which tend to have small, tight pores and smooth surfaces. Defects can vary but are typically ...

Metal Fatigue
In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure. Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal ''crystallising'' because of the brittle appearance of the fracture surface, but this has since been disproved. Most materials, such as composites, plastics and ceramics, seem to experience some sort of fatigue-related failure. To aid in predicting ...

Free-turbine Turboshaft
A free-turbine turboshaft is a form of turboshaft or turboprop gas turbine engine where the power is extracted from the exhaust stream of a gas turbine by an independent turbine, downstream of the gas turbine. The power turbine is not mechanically connected to the turbines that drive the compressors, hence the term "free", referring to the independence of the power output shaft (or spool). This is opposed to the power being extracted from the turbine/compressor shaft via a gearbox. The advantage of the free turbine is that the two turbines can operate at different speeds and that these speeds can vary relative to each other. This is particularly advantageous for varying loads, such as turboprop engines. Design A free-turbine turboshaft ingests air through an intake. The air passes through a compressor and into a combustor where fuel is mixed with the compressed air and ignited. The combustion gases are expanded through a compressor-driving turbine, and then through a "free" pow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
