Why aircraft fail

چکیده
Transport. Increasingly over the last few years, investigations have also been undertaken for insurance loss adjusters and as expert witnesses in litigation cases. While assisting in the investigation of accidents to both civil and military aircraft is an important aspect of the work, there are many examples of component failures and defects that were detected before an accident could occur, i.e. during routine maintenance and inspection operations. Many in-service aircraft are now required to operate beyond their original design life, partly as a result of the accelerating costs of replacement and also the ability to upgrade systems in old airframes. As part of the life extension program and aging aircraft audit, in recent years QinetiQ has conducted the teardown inspection of several military airframes. This involves the dismantling of a representative example of older airframes of a particular aircraft type and making a thorough inspection of each component to assess its condition. This Failure of an aircraft structural component can have catastrophic consequences, with resultant loss of life and of the aircraft. The investigation of defects and failures in aircraft structures is, thus, of vital importance in preventing further incidents. This review discusses the common failure modes observed in aircraft structures, with examples drawn from case histories. The review will also outline the investigative procedures employed in the examination of failed components.

متن کاملWhy Airplanes Crash: Causes of Accidents Worldwide
In this paper, we report the results of a detailed examination of the causes of 700 fatal aviation accidents that occurred worldwide between 1990 and 2006 in commercial passenger service. We look at both scheduled and nonscheduled and both domestic and international service. We also categorize the accident aircraft as large jets, regional and medium jets, small jets, turboprops, and piston powe...

Why do technically sound WASH sector strategies, even those that have been successful in other contexts or constitute accepted ‘best practice’, fail to improve access to water supply and sanitation, especially for the poor? Why do good sector policies, often supported by donor technical assistance, fail to get implemented? Why are seemingly successful pilot programmes not scaled up? Why are sec...

Abstract. We perform a Why-Because Analysis (WBA) starting from the information in the Executive Summary of the U.S. DoD Aircraft Accident Investigation Board report on the shootdown of two U.S. Army Black Hawk transport helicopters by U.S.A.F. F-15 fighter aircraft over Northern Iraq on 14 April 1994, during Operation Provide Comfort. We compare with the effort of Snook to perform a similar an...
