Spare parts are treated as the basis to guarantee safe and economic operation of civil aircraft, its scientific prediction reasonable configuration play an important role in perfecting integrated logistics support (ILS) achieving win-win situation stakeholders (e.g. manufacturers, operators, maintenance providers). This paper studies existing spare methods discusses future development trend fro...

Maintenance Supply Chain (MSC) involves Maintenance, Repair, and Overhaul (MRO) organizations and the relationships within and across suppliers and customers. These organizations work with the probability of equipment failure, maintenance, and the use requirements of spare parts. All of these elements increase uncertainty in this environment. Besides, it is difficult to integrate and process in...

Aircraft hydraulic systems are composed of several components connected and distributed along the aircraft. Monitoring leakage of these components are time consuming tasks, and often cover only some parts of the system. The objective of this work is to present a method to estimate hydraulic leakage and recommend maintenance and servicing tasks using aircraft standard sensors such as fluid tempe...

In order to build aircraft that are lighter and thus, use less fuel, aircraft manufacturers have begun using carbon composite material to fabricate the airframes instead of aluminum. An undesired effect of this change is the increase in severity of the indirect effects of lightning strikes to the airframe on the electrical equipment used on the aircraft (avionics). The more severe lightning tra...

The principle of Line Scan Thermography (LST) was used to develop a self-propelled infrared thermographic nondestructive testing device for the inspection large, relatively flat composite aerospace parts, such as aircraft wings. design unit allowed suppression noise from reflected radiation. new equipment, using LST method, provided defect detectability similar that achieved with classic, stati...

The imaging technique of X-ray radiography is useful for the inspection of parts used in military aircraft. Given a source/detector/object configuration, a two-dimensional radiographic image is collected. Using a series of these images, a three-dimensional image of a part is constructed in which defects can be detected. The inverse problem of interest is to estimate, to an arbitrarily high degr...

First we need to define what “FOD” is and how serious is the threat. In the aviation industry, there are two generally accepted meanings for the acronym FOD. One definition is “Foreign Object Debris”, which includes substances, debris or any articles that could potentially cause damage to a vehicle or engine (Figures 1 and 2). It is anything – large or small – inside or around aircraft and flig...
