Aircraft maintenance has always been a significantly important area as it ultimately deals with the safety of all passengers and cargo traveling in aircraft. mechanics that handle such operations have danger concerning their safety. This study concerns impact workers an aircraft chassis maintenance. The main aim is to find out whether positive or negative on mechanics. paper summarizes literatu...

Landing gear is an essential part of aircraft. However, the components landing are susceptible to degradation over life their operation, which can result in shimmy effect occurring during take-off and landing. In order reduce unplanned flight disruptions increase availability aircraft, predictive maintenance (PdM) technique investigated this study. This paper presents a case study on implementa...

An aircraft is a complex machine composed of many interrelated components and systems. When these electrical and mechanical systems are designed there is an expected life length. As the aircraft and systems age they gradually degenerate until they are no longer able to perform the functions for which they were designed. When a component or system is not functional it can be replaced or repaired...

The aim was to study hearing loss in a population of aircraft technicians and mechanics and indentify predictors. Equivalent noise levels during a working day were measured and were 70-91 dB (A). Maximal noise level was 119 dB(A). A total of 336 aircraft maintenance personnel answered a self-administered work environment questionnaire (response rate 76%) and underwent audiometric test. The mean...

1 0-7803-5846-5/00/$10.00 © 2000 IEEE Affordability and responsiveness are two key requirements for the next generation of aircraft support systems. Aircraft have to be repaired with minimum downtime and the support process has to be economical and efficient. The vision of Autonomic Logistics (AL) entails a maintenance and support system that can autonomously respond to “events”, e.g. problems ...

Aviation industry is highly dynamic and demanding in nature that time and safety are the two most important factors while one of the major sources of delay is aircraft on ground because of it complexity, a lot of machinery like vehicles are involved and lots of communication are involved. As one of the aircraft ground services providers in Hong Kong International Airport, China Aircraft Service...

In the present study, the effect of nano Al2O3 and nano graphene ceramic additives in optimizing performance and improving thermophysical properties of aircraft anti-icing/de-icing fluids was investigated. Nanoparticles were characterized by TEM, SEM and XRD methods. The thermal conductivity, surface tension and dynamic viscosity of the hybrid nanofluids were experimentally assessed for tempera...

Automated fault detection is an increasingly important problem in aircraft maintenance and operation. Standard methods of fault detection assume the availability of either data produced during all possible faulty operation modes or a clearly-defined means to determine whether the data provide a reasonable match to known examples of proper operation. In the domain of fault detection in aircraft,...

The aircraft inspection/maintenance system, which is influenced by based operators and regulated by the FAA, consists of several interrelated human and machine components. In this process, visual inspection plays a significant role in ensuring aircraft safety. To improve the quality and reliability of aircraft inspection, training and job aiding have been identified as the two most important in...
