today across the world, specific methodologies for failure investigation of responsible structures are being developed and applied extensively. Scientific discipline, known asforensic engineering, widely uses these methodologies, especially in aviation industry in order to help accidents investigation and their...
A survey of both public transport and general aviation accidents which occurred in the United Kingdom over the past 20 years will show that material failure in various forms has accounted for, or contributed to, approximately 25 per cent of the major accidents. The effects of these failures ...
The photos collected are typically stitched together to produce one final map of the survey area. If time is of the essence, fixed wing platforms are used due to their faster flight speeds; however, multi-rotors can also be used and are advantageous if a closer look at a specific point ...
ADS-B is prone to failure due to intentional or unintentional illegal interference, which in turn leads to interruption of flight monitoring, thereby increasing the risk of accidents. Through accurate trajectory prediction, real-time data can be provided when ADS-B fails, which can immediately stren...
JA804A September 25, 2014 The objective of the investigation conducted by the Japan Transport Safety Board in accordance with the Act for Establishment of the Japan Transport Safety Board (and with Annex 13 to the Convention on International Civil Aviation) is to prevent future accidents and ...
During these training flights, there were two accidents due to pilot errors. The Chilean Air Force was under great pressure from the press about the quality of these planes, which eventually led to the suspension of any further flights of the Breda. These accidents were caused mostly due to ...
Unfortunately, several failure analysis of landing gears have been reported on literature, therefore for safety reasons the root causes of these failures must be well identified in order to avoid future accidents. This paper presents a detailed analysis of the failure of an axle from the nose ...
This was an increase from 7,740 to 81,500 in 50 s. Data collection stopped during the climb due to a power failure. Fig. 4 Flight 4 Full size image Table 4 summarises the UFP concentration levels measured in this study, their phase of flight, whether a smell was noticed and aircraft...
The material specification was checked and found to be satisfactory, which indicated that the premature failure was not due to a material fault. It was observed, however, that the origin of the fatigue crack occurred at a notch in the surface of the tube. The notch would have produced a st...
Referring back to the Kevlar epoxy matrix cracking problems due to thermal cycles in Section 3.2.2.1.1, a carbon-epoxy material system cured at 350°F experiences on the order of 8 ksi thermal stress at the lowest operating temperatures and has little tendency for viscoelastic ratcheting with ...
