Aircraft Carrier Technologies are Getting Younger

Older transport aircraft are much earlier scrapped in the past: 2008 the machines to machine the average were 32 years old, by 2015, the average age was only slightly more than 24 years. Good evidence that even this value is less than 2016. There are even aircraft that are less than 15 years old and already decomposed.

Regardless of the reduced age of scrapped aircraft, the number of Aircraft Carrier Technologies that Getting Younger has fallen dramatically in recent years. In 2013 750 aircraft were dismantled. by 2015, there were just 466 and a further decline is likely this year. What is behind this? The explanation for this apparent phenomenon is that a large part of the concerns relatively modern aircraft which are currently no longer used but are parked on large surfaces in the desert the so-called Boneyards.

The long-term average annual eight percent of permanently parked aircraft be scrapped.

Airbus A320 and Boeing 737 are strikingly often scrapped due to part costs.

From the average values can be not, even airplanes in significant numbers to be scrapped that are not even 15 years old. Essentially, this is the lot sold types of Airbus A320 and Boeing 737.

In addition, he is known primarily as a space for the temporary storage of temporarily decommissioned aircrafts. There are also companies located, the aircraft dismantling and scrapping.

Since 2008 slightly more than 100 of these aircraft have been chopped, including several dozen alone by 2015. There are several reasons for this development. For one, the technical development has been very quickly. This applies in particular to the specific fuel consumption of engines steadily fallen. That has prompted individual airlines to take even relatively new aircraft from the flight operation because the following so much more economical to fly. The conversion to new engines would have been much too expensive.

Used spare parts requested, its cheaper to store used planes and disassemble them instead of buying missing parts.

There is also a completely different reason. Specifically, leasing companies have relatively young aircraft, which after the expiry of the lease came back, again rented, but rather decompose be because a wealth of components at very good prices is for sale. The latter explained it, that the major aircraft producers raise their emissions for a long time and there are many bottlenecks in the deliveries, which eventually led to strong price increases for used parts.

However sometimes planes are marginalized by the market development from the operation be scrapped. This applies in particular to the small short-haul jets with 50 passenger seats. In the time faster strong price increases for Jet fuel they were rapidly uneconomical and partly through the somewhat slower but much cheaper flying turboprops replaced partly by larger jets. This small 50 seater are now also removed by the Boneyards and decomposed.

Iran will drive the scrapping industry in the height.

The large Iranian fleet of commercial aircraft has a special feature in international comparison. As a result of long-lasting sanctions against the country were all Western aircraft manufacturers for decades across not in a position to sell their machines in the Iran. The result is a grotesque aging of Iranian airliners.

Many of them fly for more than 35 years, some for more than even 40 years.

That the Iran had recorded at the same time striking many accidents, not back on the age of the aircraft, but is on the extreme lack of spare parts. The sanctions prohibited even the sale of aircraft components of all kinds after Iran. That the age of aircraft must have no influence on their reliability, can be already from it, that the American fleet of long-range bombers is more than 60 years old. The future American strategic bomber to have even a maximum technical usage validation period of 80 years.
