In 1903 the Wright Brothers first built their first aircraft thus was the beginning of aging aircraft. There is no single criteria that defines an aircraft as ‘old’ (Kizer, 1989). As much maintenance put in to the upkeep of the aircraft, the airframe itself cannot be replaced only repaired. Since the Wright brothers created that first aircraft, the demand for aviation has increased tremendously. Since the beginning of the aircrafts life cycle there are many things that will increase the age of the aircraft including, the number of flight cycles, and the number of flight hours. The number of repairs on the aircraft also increases the age by the varying components installed. There have been many instructions enacted to combat aging aircraft …show more content…
Age does not directly cause the measured workload patterns. It is only a correlate of many other material-deterioration and maintenance-response processes that change over time (Pyles, 2003). A major discrepancy with old aircrafts is corrosion. At each of these inspection intervals corrosion must be treated and prevented, otherwise it can be catastrophic. As such was the Aloha Incident of 1988 where corrosion caused the upper fuselage to rip off during flight. This accident was the beginning of the Aging Aircraft Act and is what prompted all the safety inspections required today. Since then many other accidents have happened with aging aircraft including TWA flight 800, on 17 July 1996, where it was found that the wiring in the wing center section was deteriorated and led to the fuel tank explosion killing everyone aboard. In 2000 and 2001, it was found in Ansett Australia’s Boing 767 aircrafts had structural cracks in the engine pylons and empennage which caused a massive impact in making these aircraft grounded. These accidents and incidents have highlighted the safety implications resulting from aircraft ageing and have demonstrated the importance of effective continuing airworthiness programs (Australian Transport Safety Bureau
April 16th 1907, Joseph-Armand Bombardier, a Canadian inventor and entrepreneur was born. Bombardier grew up in the eastern Quebec village of Valcourt. The ambitious young bombardier wanted to come up with a solution to make it much easier to travel through the snow-covered roads. Through Bombardier’s earlier years, he started his own garage where he worked and honed his mechanical craft. In his spare time, Bombardier worked hard to create an automobile that could travel easily on snow.
The history of flying dates back as early as the fifteenth century. A Renaissance man named Leonardo da Vinci introduced a flying machine known as the ornithopter. Da Vinci proposed the idea of a machine that had bird like flying capabilities. Today no ornithopters exist due to the restrictions of humans, and that the ornithopters just aren’t practical. During the eighteenth century a philosopher named Sir George Cayley had practical ideas of modern aircraft. Cayley never really designed any workable aircraft, but had many incredible ideas such as lift, thrust, and rigid wings to provide for lift. In the late nineteenth century the progress of aircraft picks up. Several designers such as Henson and Langley, both paved the way for the early 1900’s aircraft design. Two of the most important people in history of flight were the Wright Brothers. The Wright Brothers were given the nickname the “fathers of the heavier than air flying machine” for their numerous flights at their estate in Kitty Hawk, North Carolina. Orville and Wilbur Wright created a motor-powered biplane in which they established incredible feats of the time. The Wright Brothers perfected their design of the heavier than air flying ma...
Aviation was big during the 1920’s. The first airplanes that were developed were made of wood and canvas, they were later modernized and than made of an increasing amount of metal during this era. Airplanes were typically only used to carrying heavy loads and for wars, but during this era they were able to start taking passengers as well. It was only in 1927 that an airport terminal in the form of a waiting room and ticket-office for airplane passenger...
Executive Summary A key factor in determining a project's viability is its cost of capital [WACC]. The estimation of Boeing's WACC must be consistent with the overall valuation approach and the definition of cash flows to be discounted. Note that this process is a forward-looking focus and is laden with uncertainty. It is how the assumptions are modeled that many costly mistakes can be made.
After World War II there was an excess of aircraft and trained pilots in the United States, which significantly increase in private and commercial flights. An increase in the use of private aircraft and large passenger planes meant an increase in the possibly of aircraft safety incidents. Even though safety measures had been put in place to tend to large number of aircraft in the skies, in late 1950’s there were two unfortunate accidents that finally led to legislation that would be a major change to the world of aviation that affects us even today. The introduction of the Federal Aviation Act of 1958 spurred several changes in aviation that eventually led to the creation of the Federal Aviation Administration.
Following World War II and the jet engine technology that emerged largely toward its end, aerospace engineers knew well that the technology had great potential for use in the commercial aviation industry. The Comet was the first aircraft to utilize jet propulsion; however, its designers failed to consider the metallurgy of the aircraft’s materials under flight conditions or the consequences of their atypical window design. The aircraft was designed by Britain’s De Havilland Aircraft Company and entered service in May 1952. After a year of service, however, the design issues mentioned above resulted in the failure of several Comet aircraft. Extensive evaluations revealed that repeated pressurization stress on the aircraft’s main cabin had caused its structure to fail.
Since the time of the World Wars and the Wright brothers, aviation has become a huge part of global society. The Orville and Wilbur Wright’s names will forever be remembered into United States history as the first men who were the first to fully realized human flight. Their successful invention of a working, powered airplane brought about whole new ways of wars, including new strategies for both offense and defense. Many technological advances might not have occurred without the need for new weapons and systems for airplanes. Travel and commerce would be much slower without the usage of airplanes. Orville and Wilbur have made a lasting impact on the world with their invention of a working, human-controlled, powered airplane; who knows what the world would be without it.
Maintenance cost- Maintaining the old aircrafts is the biggest weakness for the airlines as they have to spend a huge amount on their maintenance by which their additional overhead cost raises.
The airplanes have come a long way since the makings of the Wright brothers. In 1927 Lindbergh flew across the Atlantic Ocean to Paris in 39.5 hours all by himself. That had never been done before. Nowadays people own their own private jets and planes can carry hundreds of people along with luggage or food. But the Wright brother did more than make it possible for people to fly, they made a connection that many never thought possible. The plane brought separated families together, medicine to the sick in other countries and of course they made travel faster. The Wright brothers turned themselves into revolutionary icons with their determination and passion for the world of aviation.
Aviation has a huge environmental impact to the environment and society, the aircraft engines releases a noise that affects human life and the particulates and gases that are released from the aircraft engines contribute to climate change and increases the global warming. Despite the emission reductions from cars and more fuel-efficient and less polluting turbofan and turboprop engines, the rapid growth of air transportation in the recent years contributes to an increase in total pollution attributable to aviation. In the European Union, and increased greenhouse gas emissions from aviation increased by 87% between 1990 and 2006. Like any other form of public mass transportation that relies on resources that are extracted from the planet for e.g. Oil, and the airline cannot be considered sustainable in the long-term too. Because of the limited resources in which the Aviation relies on, it is more realistic to think how to improve the sustainability of the air transportation rather than achieving a sustainable development. Demand for air transport is growing constantly and, if this demand is to be met with all the benefits associated, the community or society must also accept the costs like; (Pollution, Aircraft noise, Environment change, risk, and resources consumption, etc.).
Introduction Plane crashes occur for a number of reasons. There seems to be a consensus with the general public that flying is dangerous, engines fail and planes crash. That is true sometimes, although the majority of plane crashes occur largely due to a combination of human error and mechanical failure. In many aviation accidents mechanical failure has been a contributing factor. It is impossible, however, to blame plane crashes on one reason, since events leading up to an accident are so varied.
Aviation industry deals with more than thousands of people and also spending millions of funds in order to meet the requirements, satisfy the necessities of people and to produce state-of-the-art aircraft. With its objective it is significant to consider the hazards involved and bring out an output with the least extent and under control risks to prevent any loss in terms of life and even profit.
After studying the Aloha aircraft accident in 1933, our group is interested in the investigation in Human performances factors in maintenance and inspection. We have divided the investigation into 5 aspects:
The primary cause is of airplane accidents does at some stage contain an element of a person being unable to discharge his duties correctly and in an accurate manner. More than 53% accidents are the result of ignorance or faults by the pilot during flight. Other staff is responsible for about 8% accidents. The most obvious errors by pilot are made during the take off or landing on the runway. Additionally errors can occur during the maintenance of the airplane outside the plane, whereby a lack of thorough inspection and oversight can lead to complication during mid-flight. Fueling and loading of the plane also sometimes create problems (Shapiro, 2001).
