In aviation, a flameout is the run-down of a jet engine or other turbine engine due to the extinguishment of the flame in its combustor. The loss of flame can have a variety of causes, such as fuel starvation, excessive altitude, compressor stall, foreign object damage deriving from birds, hail, or volcanic ash, severe precipitation, mechanical failure, or very low ambient temperatures.
Helicopter flight controls are used to achieve and maintain controlled aerodynamic helicopter flight. Changes to the aircraft flight control system transmit mechanically to the rotor, producing aerodynamic effects on the rotor blades that make the helicopter move in a desired way. To tilt forward and back (pitch) or sideways (roll) requires that the controls alter the angle of attack of the main rotor blades cyclically during rotation, creating differing amounts of lift at different points in the cycle. To increase or decrease overall lift requires that the controls alter the angle of attack for all blades collectively by equal amounts at the same time, resulting in ascent, descent, acceleration and deceleration.

On October 14, 2004, Pinnacle Airlines Flight 3701 crashed near Jefferson City, Missouri while flying from Little Rock National Airport to Minneapolis–Saint Paul International Airport. The two pilots, the only occupants, were killed. Federal investigators determined the crash was due to the pilots' unprofessional behavior and disregard for training and procedures.
Pakistan International Airlines Flight 688 was a domestic passenger flight from Multan to Islamabad with a stopover in Lahore, operated by Pakistan's flag carrier Pakistan International Airlines. On 10 July 2006, the aircraft operating the route, a Fokker F27, crashed into a mango garden after one of its two engines failed shortly after takeoff from Multan International Airport. All 41 passengers and four crewmembers on board were killed.
Branch County Memorial Airport is a county-owned, public-use airport located three nautical miles (6 km) west of the central business district of Coldwater, a city in Branch County, Michigan, United States. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a local general aviation facility.
Mohawk Airlines Flight 405, a Fairchild Hiller FH-227 twin-engine turboprop airliner registered N7818M, was a domestic scheduled passenger flight operated by Mohawk Airlines that crashed into a house within the city limits of Albany, New York, on March 3, 1972, on final approach to Albany County Airport, New York, killing 17 people. The intended destination airport lies in the suburban Town of Colonie, about 4 miles north of the crash site.
Autorotation is a state of flight in which the main rotor system of a helicopter or other rotary-wing aircraft turns by the action of air moving up through the rotor, as with an autogyro, rather than engine power driving the rotor. The term autorotation dates to a period of early helicopter development between 1915 and 1920, and refers to the rotors turning without the engine. It is analogous to the gliding flight of a fixed-wing aircraft. Some trees have seeds that have evolved wing-like structures that enable the seed to spin to the ground in autorotation, which helps the seeds to disseminate over a wider area.
Airbus Industrie Flight 129 was an Airbus Industrie A330-321 test flight that ended in a crash on 30 June 1994 at Toulouse-Blagnac Airport, killing all seven people aboard. The last test flown was to certify the plane's takeoff capability with a single engine failure. It was the first fatal accident involving an Airbus A330 as well as the first hull loss of the type. It remained the only fatal accident involving an A330 until the crash of Air France Flight 447 on 1 June 2009.
A turbine engine failure occurs when a turbine engine unexpectedly stops producing power due to a malfunction other than fuel exhaustion. It often applies for aircraft, but other turbine engines can fail, like ground-based turbines used in power plants or combined diesel and gas vessels and vehicles.
LOT Polish Airlines Flight 007 was an Ilyushin Il-62 that crashed near Okęcie Airport in Warsaw, Poland, on 14 March 1980, as the crew aborted a landing and attempted to go-around. All 87 crew and passengers died. It was caused by the disintegration of one of the turbine discs in one of the plane's engines, leading to uncontained engine failure. The turbine disc was later found to have manufacturing faults.
Spanair Flight 5022 was a scheduled domestic passenger flight from Barcelona–El Prat Airport to Gran Canaria Airport, Spain, with a stopover in Madrid–Barajas Airport that crashed just after take-off from runway 36L at Madrid-Barajas Airport to Gran Canaria Airport at 14:24 CEST (12:24 UTC) on 20 August 2008. The aircraft was a McDonnell Douglas MD-82, registration EC-HFP. Of the 172 passengers and crew on board, 154 died and 18 survived.
This article briefly describes the components and systems found in jet engines.
Imperial Airlines Flight 201/8 was a charter flight by the United States Army to transport new recruits to Columbia, South Carolina for training. On November 8, 1961, the aircraft crashed as it attempted to land at Byrd Field, near Richmond, Virginia. This was the second deadliest accident in American history for a single civilian aircraft.
An airbreathing jet engine is a jet engine in which the exhaust gas which supplies jet propulsion is atmospheric air, which is taken in, compressed, heated, and expanded back to atmospheric pressure through a propelling nozzle. Compression may be provided by a gas turbine, as in the original turbojet and newer turbofan, or arise solely from the ram pressure of the vehicle's velocity, as with the ramjet and pulsejet.
There are two very different definitions of hot start commonly used in aviation – one for turbine engines and one for reciprocating fuel injected engines.
Plumes of volcanic ash near active volcanoes are a flight safety hazard, especially for night flights. Volcanic ash is hard and abrasive, and can quickly cause significant wear to propellers and turbocompressor blades, and scratch cockpit windows, impairing visibility. The ash contaminates fuel and water systems, can jam gears, and make engines flame out. Its particles have low melting points, so they melt in the engines' combustion chamber then the ceramic mass sticks to turbine blades, fuel nozzles, and combustors—which can lead to total engine failure. Ash can also contaminate the cabin and damage avionics.
Centurion Air Cargo Flight 164 was a chartered international cargo flight, flying from Bogota's El Dorado International Airport while en route to Miami International Airport. The flight was operated by Kalitta Air and the aircraft was wet leased by Centurion Air Cargo. On 7 July 2008, the aircraft, a Boeing 747-209BSF registered as N714CK, crashed shortly after takeoff. All aboard suffered injuries, but none were killed. Two people on the ground were killed after the plane slammed into a farm. The crash was the second crash of a Boeing 747 in 2008 in Kalitta Air service, after a previous accident at Brussels in May.
Pakistan International Airlines Flight 661 was a Pakistani domestic passenger flight from Chitral to Islamabad, operated by Pakistan's flag carrier Pakistan International Airlines. On 7 December 2016, the aircraft serving the route, an ATR 42-500 twin-turboprop, lost control and crashed near Havelian following an engine failure. All 47 people on board died, including singer-turned-preacher and entrepreneur Junaid Jamshed, and the Deputy Commissioner of the District of Chitral.
On 17 March 1977 a British Airtours Boeing 707 being used for pilot training crashed and caught fire during its take-off roll at Glasgow Prestwick Airport. All four crew members on board survived.
