The latest planes of Boeing 737 family were still made back in 1988, and more than 500 of these airplanes are in use until now. The Boeing 737 JT&D, which belonged to I Tec Air, crashed last year in Kyrgyzstan; it happened shortly after the European Union prohibited this company to fly to Europe, because of the tremendously low level of security. Such incidents help to explain why this model is on the top list of airplanes, which are so frequently prone to crashes. Old planes need more intensive care than the new ones. However, they are in operation by budget air companies, which do not have enough funds for normal technical service and teaching pilots.
Using the data of Ascend London insurance consultancy the BusinessWeek edition made the list of the most dangerous planes on the basis of the air crash quantity with fatal outcome. The rate contained the models of planes, which are in operation all over the world in more than 100 units. Air crashes connected with terrorism were not included.
1. Boeing 737 JT8D
One crash per: 507 500 flying hours
Years of production: 1967-1988
Planes in operation: 517
The first version of Boeing 737 is recognized to be the most wrecking plane in the world. One air crash with a fatal outcome covers 507 500 flying hours. The less is the figure the more is the probability of crash. 517 more planes of this model are still in operation in poor countries. About 30- year-old Boeing 737 JT8D, that was in operation by Itek Air company, crashed not far from Bishkek in August 2008. 68 people died in that crash.
One crash per: 549 900 flying hours
Years of production: 1974 – present
Planes in operation: 247
This model is mostly met in the countries of the former Soviet Union, Near East and Africa. One of the biggest air crashes of IL 76 happened in 2003. The crashed plane belonged to Iranian air company Iran Revolutionary Guard, 275 people died in that crash.
One crash per: 1 041 000 flying hours
Years of production: 1971-present
Planes in operation: 336
This model is also mainly in the parks of air companies of the former Soviet Union, and performs the flights in the inner airlines mainly. Since 2002 four air crashes took place in Iran with TU 154. The latest air crash happened this year in July 15: TU 154 of Iranian Air Company Caspian Air going from Tehran to Yerevan. 168 people died.
4. Airbus A310
One crash per: 1 067 700 flying hours
Years of production: 1983-1998
Planes in operation: 191
Big air companies have already put out of operation this model of European air constructor Airbus. However, some poor countries like Pakistan International Airlines, actively keep it in operation. The latest air crash of this kind of airliner happened this year in June 30 when A310 which belonged to Yemenia Airlines and was going from Yemen to Comoro Islands fell into the open sea. 153 people died, only a 12 –year-old girl was saved.
5. McDonnell-Douglas DC-9
One crash per: 1 068 700 flying hours
Years of production: 1965-1982
Planes in operation: 315
The McDonnell-Douglas company stopped its existence after merging with Boeing in 1997, but not young already DC-9 are still in operation by the Delta Airlines company, and also by many other small air companies in the world. In April there was a crash of DC-9 of the Hewa Bora Airways2008 in the Republic of Congo, 44 people died then.
One crash per: 1 087 600 flying hours
Years of production: 1964-1986
Planes in operation: 223
The most mass plane of the soviet civil aviation is still widely used by the Russian air companies and the former Soviet republics. As soon as the level of the engine noise of the liner does not satisfy the western European standards TU 134 is mainly used in inner flights. One of the biggest crashes happened in August 2004, when the “Volga – Aviaexpress” plane crashed and all the 43 people on board died.
7. Boeing 727
One crash per: 2 306 300 flying hours
Years of production: 1963-1984
Planes in operation: 412
Most of the biggest air companies have already replaced the old Boeing 727 for more modern planes. The United Airlines air company e.g. gave one such liner to the Chicago museum of science and industry in 1993. However, this plane is still widely used out of the USA, especially by charter air companies. One of the air crashes with this plane happened in African Benin on Christmas 2003. 151 people died then.
8. McDonnell-Douglas MD-80
One crash per: 2 332 300 flying hours
Years of production: 1980-1999
Planes in operation: 923
This model, made to replace DC-9, was taken out of production recently and is still in use by the Delta American Air Company, as well as big European companies, Alitalia and SAS in particular. In August 2008 the plane of this model which belonged to the Spanish Air company Spanai crashed when going from Madrid to Canary Islands. 153 people died then.
9. McDonnell-Douglas DC-10
One crash per: 2 908 800 flying hours
Years of production: 1971-1989
Planes in operation: 153
DC 10 belongs to a rare type of planes whose security increases with its age. Fatal air crashes with this liner in 70’s brought to the significant changes and improvements in the construction of the airline. As a result the last incident with the people died happened in 1999 when the liner of the former French AOM company crashed in Guatemala. Currently the plane is mainly used by freight carrier and charter companies. The last air company which used DC 10 for regular flights was Biman Bangladesh.
10. McDonnell-Douglas MD-11
One crash per: 3 668 800 flying hours
Years of production: 1990-2001
Planes in operation: 187
MD11 turned to be not a very successful model as it had not high indexes on effectiveness of fuel using and other parameters. Anyway the Finnair and KLM air companies still use these liners, but mainly for freight carrier. The last time the plane of this model crashed in 1999. At that time the MD 11 of the China Airlines company got burned while landing in Hong Kong during the typhoon, three people died.
It is necessary to mention that the list made by BusinessWeek is somewhat different from the statistics made by the bureau on accidents by air transport JACDEC, though according to the version of this bureau the most wrecking in the history of civil aviation are the planes of Boeing Company.
