“…Where risk assessments have been used, they have been addressed to the implementation of new systems, rather than the inspection decisions themselves. For example, the authors of [64] provided a risk assessment for the implementation of the structural health monitoring, and similarly, the authors of [65] for a detection procedure.…”

Risk assessment methods are widely used in aviation, but have not been demonstrated for visual inspection of aircraft engine components. The complexity in this field arises from the variety of defect types and the different manifestation thereof with each level of disassembly. A new risk framework was designed to include contextual factors. Those factors were identified using Bowtie analysis to be criticality, severity, and detectability. This framework yields a risk metric that describes the extent to which a defect might stay undetected during the inspection task, and result in adverse safety outcomes. A simplification of the framework provides a method for go/no-go decision-making. The results of the study reveal that the defect detectability is highly dependent on specific views of the blade, and the risk can be quantified. Defects that involve material separation or removal such as scratches, tip rub, nicks, tears, cracks, and breaking, are best shown in airfoil views. Defects that involve material deformation and change of shape, such as tip curl, dents on the leading edges, bents, and battered blades, have lower risk if edge views can be provided. This research proposes that many risk assessments may be reduced to three factors: consequence, likelihood, and a cofactor. The latter represents the industrial context, and can comprise multiple sub-factors that are application-specific. A method has been devised, including appropriate scales, for the inclusion of these into the risk assessment.

“…They considered the cost of inspection (work force and equipment), the cost of repair (material and spare parts) and the risk due to the uncertainty linked to any special event or unexpected severe damage. A simulation case study was developed by Sun et al in order to test the proposed maintenance cost modelling [23]. Once again, inspection and repair costs were included in the analysis and once again, several probability functions have been defined in order to quantify the unscheduled operations.…”

“…The database was populated with information derived from several producers, in terms of geometrical characteristics, autonomy, tank capacity, and maintenance costs for the service life. Data were recovered using the scientific literature [23,25,30,31]. Appendix A summarizes the input data recovered and stocked before starting the analysis.…”

Economic and Environmental Sustainability for Aircrafts Service Life

et al. 2020

Aircrafts are responsible for a significant environmental impact mainly due to the air pollution caused by their motors. The use of composite materials for their production is a way to significantly reduce the weight of the structures and to maximise the ratio between the payload weight and the gasoline consumption. Moreover, the design phase has to consider the cost of different operations performed during the aircraft service life. During the entire life cycle, one of the main costs is the maintenance one. In the current literature, there is a lack of knowledge of methods for maintenance cost estimation in the aircraft industry; moreover, very few environmental assessment methods have been developed. Thus, the aim of this paper is to define a new method to support the aircraft design process; both the environmental and the economic dimensions have been included with the purpose of assessing the aircraft sustainability during its service life. A green index has been identified mixing the maintenance cost and an environmental parameter with the aim of identifying the greenest solution. A final practical application shows the feasibility and the simple application of the proposed approach.

“…The crucial factors that are calculated in the cost analysis include sensor cost, installation cost, inspection cost, cost caused by extra weight, cost reduction due to less number of labor and discount due to maintenance downtime reduction [23]. The maintenance cost can be reduced significantly, as compared to the current traditional NDT while sustaining the level of risk [40]. The technology and installation of this system may incur a higher cost due to the increased amount of sensors installed (depends on aircraft size), and well beyond the affordability of many small and medium industries [23].…”

The Structural Health Monitoring (SHM) system is a method for evaluating and monitoring the integrity of the structure. It has been widely used in various engineering sectors, such as in aerospace, civil and energy sectors due to its ability to react to structural changes on an online basis or in real-time monitoring. The SHM system was able to evolve and work in a variety of structures or components due to the rapid development of sensor technology. It is believed that SHM will become an important tool in various industries for structural monitoring in future years. The paper presents a summary of the latest SHM technology in civil and aviation technology applications as well as the challenges in cost analysis and certification issues for the implementation of SHM.
