Abstract
One of the most complex engineering system is failure of an aircraft component which leads to the catastrophic consequences which result in events that cause loss of life and also damage the aircraft.
I’m doing investigation on defect and failure in the aircraft structures which is important for the prevention of further catastrophic incidents. One of the main reason for the failure of the aircraft components or structure under high stress which is during the operation where the component no longer bear the stress which is imposed.
Here in the analysis of stress on the piston road end is carried out with the finite element techniques. The most common cause for the failure of the aircraft is complex engineering system that causes

The stress raiser which is in the nature of geometrical or in metallurgical or combination of two. Geometrical stress raiser in the shape of the parts such as step changes in diameter, sharp corners and surface discontinuities like notches and machining marks etc. are non-uniformities. Metallurgical stress are stress raiser which may be corrosion pits, brittle second-phase particles, gross metallic inclusions, quench cracks etc. Also, the initiation of fatigue failures where microstructure of the material plays a vital role but also the fatigue crack to cause failure of the material during the progressive growth. Near free surface Fatigue initiation occurs frequently, where nominal stress will be higher. While doing manufacturing and fabrication processes where machining can form surface irregularities or discontinuities which is the point of stress concentration also initiate the fatigue
Handling and operating an airplane comes with great risk, but these risks that are present are handled with very different attitudes and dealt with in different ways depending on the environment the pilots are in.
Elastic strain region at small and big end of connecting rod is shown in figure no. 10. The maximum and minimum equivalent strain values are 0.00033975 and 2.1407e-10 respectively. Due to applied pressure there will be change in original dimensions of the connecting rod and hence strain developed can be
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.
Many people are amazed with the flight of an object, especially one the size of an airplane, but they do not realize how much physics plays a role in this amazing incident. There are many different ways in which physics aids the flight of an aircraft. In the following few paragraphs some of the many ways will be described so that you, the reader, will realize physics at work in the world of flight.

In conclusion, many contribution factors led to the Crossair flight 3597 crash but is mainly triggered by Crossair’s incapability of assessment, pilot error and lastly the air traffic controller. Analysis of a flight crash is important so that we will know the causes, thus being able tackle it, making sure that there are no other flight crashes like Crossair flight 3597.
Safety in the ethics and industry of aerospace technology is of prime importance for preventing tragic malfunctions and crashes. Opposed to automobiles for example, if an airplane breaks down while in mid-flight, it has nowhere to go but down. And sadly it will often go down “hard” and with a high probability of killing people. The Engineering Code of Ethics states first and foremost that, “Engineers shall hold paramount the safety, health and welfare of the public.” In the aerospace industry, this as well holds very true, both in manufacturing and in air safety itself. Airline safety has recently become a much-debated topic, although arguments over air safety and travel have been going ...
Weather conditions- Sometimes the bad weather conditions become the huge problem for the aircrafts as they are not able to operate in bad conditions by which they get losses.

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.
Fatigue in aviation has always been a significant issue when it comes to the safety of the crew and passengers. Fatigue in flight is not the only issue. There is also a serious safety issue in other areas of aviation such as maintenance, air traffic control (ATC), and even in areas such as baggage claim and gate security. One can find evidence of fatigue in just about every aspect of daily life. A majority of vehicle accidents can be contributed to fatigue in one way or another. One can even see it in the late night college student trying to finish a paper before its deadline. Although the last example doesn’t have any serious safety concerns it is still a very real instance of fatigue. The area of transportation has seen thousands of incidents where fatigue has
This report is based upon extensive library and internet research as well as an interview with Zaman Qamar, performance engineer at General Motors. He is one of the team members for crash and safety department which deals with accidental issues during severe crash.
As the development of aviation industry grows, more and more aircraft crashes occur. There are many reasons that lead to aircraft crashes, but one of them, is because of improper aircraft maintenance. Why is proper aircraft maintenance so important? Proper aircraft maintenance is critical in order to keep the aircraft can function properly, every aircraft part is in good condition and ensure the safety of pilots and passengers. Proper maintenance has many parts. The most common part is inspections, which pilots do them every day; the main part is overhaul and repair of an aircraft; and maintenance documentation is another important part of aircraft maintenance which improper maintenance documentation has caused many incidents.
This term paper reviews the three most common catagories of aviation accident causes and factors. The causes and factors that will be discussed are human performance, environmental, and the aircraft itself. Although flying is one of the safest means of transportation, accidents do happen. It is the investigators job to determine why the accident happened, and who or what was at fault. In the event of an accident, either one or all of these factors will be determined as the cause of the accident. Also discussed will be one of the most tradgic plane crashes in aviation history and the human factors involved.
