The Convair CV-240 is an American airliner produced by Convair from 1947 to 1954, initially as a possible replacement of the ubiquitous Douglas DC-3. Featuring a more modern design, the 240 series was able to make some inroads as a commercial airliner and also had a long development cycle which resulted in a number of civil and military variants. Thouogh reduced in numbers by attrition, the various forms of the "Convairliners" continue to fly into the 21st century.
Like every other major type in long service and operation, accidents and incidents have been recorded that have substantially reduced the numbers flying. The following list is typical of such a record of operational use.
Allegheny Airlines was a local service carrier that operated out of Pittsburgh, Pennsylvania, from 1952 to 1979, with routes primarily located in the eastern U.S. It was the forerunner of USAir that was subsequently renamed US Airways, which itself merged with American Airlines. Its headquarters were at Washington National Airport in Arlington County, Virginia.
The Antonov An-28 is a twin-engined light turboprop transport aircraft, developed from the Antonov An-14M. It was the winner of a competition against the Beriev Be-30, for use by Aeroflot as a short-range airliner. It first flew in 1969. A total of 191 were built and 16 remain in airline service as at August 2015. After a short pre-production series built by Antonov, it was licence-built in Poland by PZL-Mielec. In 1993, PZL-Mielec developed its own improved variant, the PZL M28 Skytruck.
Spantax S.A. was a former Spanish leisure airline headquartered in Madrid that operated from 6 October 1959 to 29 March 1988. Spantax was one of the first Spanish airlines to operate tourist charter flights between European and North American cities and popular Spanish holiday destinations and was considered a major force in developing 20th-century mass tourism in Spain. Its popularity and image faded from the 1970s onward when a series of crashes and incidents revealed safety deficits, which, combined with rising fuel costs and increasing competition, resulted in the company facing severe financial difficulties that led to its demise in 1988.
American Airlines Flight 625, a Boeing 727-100, crashed at St. Thomas, U.S. Virgin Islands on April 27, 1976, while on a domestic scheduled passenger flight originating at T. F. Green Airport in Rhode Island and ending at Saint Thomas, United States Virgin Islands, with an intermediate stop at John F. Kennedy International Airport. 37 out of the 88 passengers on board died in the accident.
Kelowna Flightcraft Air Charter trading as KF Cargo and Kelowna Flightcraft trading as KF Maintenance and Engineering is a cargo airline based in Kelowna, British Columbia, Canada. It operates long term cargo charters for couriers and freight companies, forest fire patrols, and aircraft sales and leasing in Canada and worldwide. It also provides maintenance and aircraft manufacturing services.
Compagnie Africaine d'Aviation, renamed FlyCAA in 2013, is a regional airline from the Democratic Republic of the Congo, based at N'djili Airport in Kinshasa. It offers an extensive network of domestic scheduled passenger flights, as well as cargo flights. Due to safety and security concerns, CAA has been included in the list of air carriers banned in the European Union.
The Convair CV-240 is an American airliner that Convair manufactured from 1947 to 1954, initially as a possible replacement for the ubiquitous Douglas DC-3. Featuring a more modern design with cabin pressurization, the 240 series made some inroads as a commercial airliner, and had a long development cycle that produced various civil and military variants. Though reduced in numbers by attrition, various forms of the "Convairliners" continue to fly in the 21st century.
In an internal combustion engine, fuel starvation is the failure of the fuel system to supply sufficient fuel to allow the engine to run properly, for example due to blockage, vapor lock, contamination by water, malfunction of the fuel pump or incorrect operation, leading to loss of power or engine stoppage. There is still fuel in the tank(s), but it is unable to get to the engine(s) in sufficient quantity. By contrast, fuel exhaustion is an occurrence in which the vehicle in question becomes completely devoid of usable fuel, with results similar to those of fuel starvation.
North Central Airlines was a local service carrier, a scheduled airline in the Midwestern United States. Founded as Wisconsin Central Airlines in 1944 in Clintonville, Wisconsin, the company moved to Madison in 1947. This is also when the "Herman the duck" logo was born on Wisconsin Central's first Lockheed Electra 10A, NC14262, in 1948. North Central's headquarters were moved to Minneapolis–St. Paul in 1952.
As of July 2020, a total of 64 Boeing 747 aircraft, or just above 4% of the total number of 747s built, first flown commercially in 1970, have been involved in accidents and incidents resulting in a hull loss, meaning that the aircraft was either destroyed or damaged beyond economical repair. Of the 64 Boeing 747 aircraft losses, 32 resulted in no loss of life; in one, a hostage was murdered; and in one, a terrorist died. Some of the aircraft that were declared damaged beyond economical repair were older 747s that sustained relatively minor damage. Had these planes been newer, repairing them might have been economically viable, although with the 747's increasing obsolescence, this is becoming less common. Some 747s have been involved in accidents resulting in the highest death toll of any civil aviation accident, the highest death toll of any single airplane accident, and the highest death toll of a midair collision. As with most airliner accidents, the root of cause(s) in these incidents involved a confluence of multiple factors that rarely could be ascribed to flaws with the 747's design or its flying characteristics.
On December 27, 1968, North Central Airlines Flight 458 crashed into a hangar while attempting a night landing in poor weather at O'Hare International Airport in Chicago, Illinois, in the United States. Of the 41 passengers and four crew members, only 17 passengers and one crew member survived. One person was killed and six were injured on the ground.
Allegheny Airlines Flight 737 was a Convair CV-580, that crashed while attempting to land at Bradford Regional Airport in Bradford, Pennsylvania on January 6, 1969. Eleven of the 28 occupants on board were killed.
The Antonov An-12 is a transport aircraft designed and manufactured by the Ukrainian manufacturing and services company Antonov. Given the long operational history of the An-12, more than 190 An-12s have crashed involving many casualties. The An-12 has also been involved in a number of aviation incidents.
Allegheny Airlines Flight 604 was a regularly scheduled daily flight from Pittsburgh International Airport in Pittsburgh, Pennsylvania to Newark Liberty International Airport in Newark, New Jersey via DuBois, Philipsburg, Williamsport and Wilkes-Barre/Scranton. Forty occupants were on board when during the Williamsport to Wilkes-Barre/Scranton leg a right engine failure and subsequent failure to follow engine out procedures by the flight crew caused the aircraft to crash northeast of the Williamsport Regional Airport.
Delta Air Lines Flight 9877 was a crew training flight operated on a Douglas DC-8. On March 30, 1967, it lost control and crashed into a residential area during a simulated engine-out approach to Louis Armstrong New Orleans International Airport.
Sierra Pacific Airlines Flight 802 was a charter flight from Bishop, California to Burbank, California that crashed into the White Mountains on the evening of March 13, 1974. The aircraft, carrying a movie production crew, crashed for undetermined reasons, killing all 36 occupants on board. To this day, the crash remains one of only three aviation accidents to be unsolved by the National Transportation Safety Board (NTSB), and it stands as the fourth-deadliest crash of a Convair CV-440 to date.
