2008 Chelyabinsk Antonov An-12 Crash
On 26 May 2008, Moskovia Airlines Flight 9675, a Moskovia Airlines An-12 cargo aircraft crashed near Chelyabinsk, Russia. After taking off for a flight to Perm, it turned back due to a fire on board and crashed from the airport, killing all nine crew members. Background The aircraft, registered RA-12957 (cn 88345508), was built in 1968. After transporting a cargo of cash from Moscow to Chelyabinsk, it was operating as an empty flight numbered GAI9675 to Perm. Flight During the pre-takeoff checklist, the crew noted warnings about a power supply failure in engines 1 and 2, but ignored them, as recorded by the CVR: *Flight radio operator: "Sanya." (name of the engineer) *Flight engineer: "Yes?" *Flight radio operator: "Number two failed" *Instructor pilot: "And number one too" *Flight radio operator: "Alternator" *A crew member: "Screw it" *Flight radio operator: "Here we go" The investigation team concluded that "here we go" probably referred to successful reactivation of the ...

Chelyabinsk Balandino Airport
Chelyabinsk Airport is an airport in Russia located 18 km north of Chelyabinsk. It services large airliners and can park up to 51 aircraft. It also serves as a secondary hub for Ural Airlines and Yamal Airlines. History Passenger flights to Chelyabinsk were served by Chelyabinsk Shagol Airport from 1938 and until it was repurposed for military only use. The current Chelyabinsk airport, initially called Balandino Airport, was opened in late 1953 with a passenger terminal and a dirt runway. The runway was paved in December 1962. A year later, the first jet plane (a Tu-104) arrived to the airport. A new terminal was built in 1974 which remains in service to this day as one of the terminal buildings. In 1994, the government-owned airport was privatized and started its first international flights. Passenger traffic reached 1.1 million and declined heavily during the 1990s. In 2013, the airport handled 1.2 million passengers, breaking the Soviet-time record. The new, longer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flaps (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduci ...

Accidents And Incidents Involving The Antonov An-12
An accident is an unintended, normally unwanted event that was not directly caused by humans. The term ''accident'' implies that nobody should be blamed, but the event may have been caused by unrecognized or unaddressed risks. Most researchers who study unintentional injury avoid using the term ''accident'' and focus on factors that increase risk of severe injury and that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been caused by humans, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car wrecks are not true accidents; however English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Types Physical and non-physical Physical examples of accidents include unintended motor vehicle collisions, falls, being injured by touching something sharp or hot, or bumping into someth ...

Aviation Accidents And Incidents In Russia
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as 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 which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...

Propair Flight 420
Propair Flight 420 (PRO420) was a scheduled domestic passenger flight from Montreal, Quebec to Peterborough, Ontario. The flight was carried out by Propair, a charter airline based in Rouyn-Noranda, Quebec, using a Fairchild Metroliner SA226. On 18 June 1998, the aircraft suffered an in-flight fire shortly after take-off from Dorval and the crew elected to conduct an emergency landing at Montréal–Mirabel International Airport. The intense heat of the fire caused a structural failure in the left wing during the landing and the aircraft crashed, resulting in the deaths of all 11 passengers and crew on board. The investigation conducted by the Canadian Transportation Safety Board revealed that the left brakes of Flight 420 had overheated during take-off, causing a fire inside the wheel-well which destroyed warning systems, as a result of which the crew was unaware of the severity of the fire, which subsequently ruptured hydraulic pipe-lines and spread to the left wing.

Caspian Airlines Flight 7908
Caspian Airlines Flight 7908 was a scheduled commercial flight from Tehran, Iran, to Yerevan, Armenia, that crashed near the village of Jannatabad, outside the city of Qazvin in north-western Iran, on 15 July 2009. All 153 passengers and 15 crew on board died. The crash was the fourth deadliest aviation incident in Iran behind Iran Air Flight 655 (1988), the Iran Ilyushin Il-76 crash (2003), and Ukraine International Airlines Flight 752 (2020). It was also the second-deadliest aviation incident in 2009 behind Air France Flight 447. The subsequent crash investigation found that the incident had been caused by fatigue failure and consequent disintegration of a rotor disc in the left hand engine (engine #1). In addition to the failure of that engine, fragments of the disc severed two of the three hydraulic control systems, and damaged fuel lines for the centre engine (engine #2). Fuel leaking from these damaged lines ignited, causing a large fire which then destroyed components t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Moorea Flight 1121
Air Moorea Flight 1121 was a de Havilland Canada DHC-6 Twin Otter which crashed into the ocean shortly after takeoff from Moorea Airport on Moorea Island in French Polynesia on 9 August 2007, killing all 20 people on board. It was bound for Tahiti's Fa'a'ā International Airport on a regular 7-minute service, one of the shortest on earth, scheduled a day. The crash resulted from loss of control due to failure of the airplane's elevator cable. Frequent takeoff and landing are believed to have been a major factor in the crash, because of wear and tear on the elevator cables, inspected only at fixed time intervals, regardless of usage. Another factor may have been jet-blast from large planes pushing back from the ramp at Fa'a'ā International. Background The aircraft, registration F-OIQI, serial number 608, was a de Havilland Canada DHC-6-300 Twin Otter powered by two Pratt & Whitney Canada PT6A-27. As of 8 August 2007, the airframe had flown 55,044 cycles in approximat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanical Failure
Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs. Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively. It assures that the construction will perform its designed function during reasonable use, for as long as its intended life span. Items are constructed with structural integrity to prevent catastrophic failure, which can result in injuries, severe damage, death, and/or monetary losses. ''Structural failure'' refers to the loss of structural integrity, or the loss of load-carrying capacity in either a structural component or the structure itself. Structural failure is initiated whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smoke Inhalation
Smoke inhalation is the breathing in of harmful fumes (produced as by-products of combusting substances) through the respiratory tract. This can cause smoke inhalation injury (subtype of acute inhalation injury) which is damage to the respiratory tract caused by chemical and/or heat exposure as well as possible systemic toxicity after smoke inhalation. Smoke inhalation can occur from fires of various sources such as residential, vehicle, and wildfires. Morbidity and mortality rates in fire victims with burns are increased in those with smoke inhalation injury. Victims of smoke inhalation injury can present with cough, difficulty breathing, low oxygen saturation, smoke debris and/or burns on the face. Smoke inhalation injury can affect the upper respiratory tract (above the larynx), usually due to heat exposure, or the lower respiratory tract (below the larynx), usually due to exposure to toxic fumes. Initial treatment includes taking the victim away from the fire and smoke, give 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Bou ...
