The vision of the Turkish Republic is to surpass the level of contemporary civilization, and one of the main principles to achieve this is "The future is in the skies." To make this a reality, it is imperative to establish a national and domestic aviation industry. The first step towards this goal is to ensure the safe operation of aircraft, which requires a maintenance management system. To create and use the necessary maintenance documents, an international standard management process should be followed for airframe manufacturers and component and part manufacturers in the aviation industry. Airline operators should then create their maintenance documentation according to this system and work with airplane maintenance organizations to ensure the airworthiness of their aircraft. This study discusses and evaluates the documents used within the essential management and organization principles framework, primarily focusing on the aircraft maintenance management system.

“…Maintenance of critical equipment to ensure high levels of reliability, availability, and performance is one of the major concerns on today's industrial sector especially for rotation machines [1][2][3][4] and other conventional type machines [5][6][7][8] subjected to cyclic loading. Unexpected failures can lead to substantial losses, either from the maintenance procedure itself or from the resulting production halts [9][10][11][12]. In order to proactively prevent failure of components, failure modes in functional component's caused by the damage/fracture modes of the materials should be comprehensively determined.…”

The semolina purifier is a machine used in the production phase in flour factories and is exposed to fatigue loads. In this study, the reason for the damage when a semolina purifier machine breaks during use and the improvements that need to be made in the design are discussed. For this purpose, a finite element model (FEM) was created using ABAQUS software. As a result of the analysis, it was determined that the design of the machine support platform should be improved. A two-stage strengthening alternative is designed. The cyclic loads applied by the twin motors that move the machine screens are applied in the FEM model. The deformations and stresses occurring in the reinforced and existing design machine base plate were compared. The results showed that, the maximum equivalent stress level can be reduced from 86 MPa to 35 MPa by design improvements made on the base plate.

“…It is well-known that under service conditions, the stress and strain concentration effects of corrosion pits can make them act as sites for fatigue crack initiation and a consequent reduction in service lifetimes, compared to where pits are absent. [1][2][3][4][5] Cases of catastrophic fatigue failures that resulted from pre-pitting have been reported in aircraft components, [6][7][8] rail wheels, 9,10 steam turbine blades, 11,12 oil and gas pipeline, 13 and automotive components. 14,15 In most of these cases, failure lifetimes were observed to be significantly less than the designed service lifetimes.…”

The influence of separation distance between pre-induced corrosion pits on both crack initiation and fatigue lifetimes is studied in an air environment by testing specimens containing pit pairs in the low-stress, high cycle fatigue regime. The results of these tests are compared with equivalent tests with samples containing similar sized single pit. Within the scope of pit sizes and separation distances investigated, when the separation distance is below a threshold, decreasing the separation distance between pits leads to earlier onset of crack initiation and decreased fatigue lifetimes; this threshold being dependent on the applied stress and relative pit sizes. When the separation distance is above this threshold, multiple pits tend to behave independently of each other. The implication of the results from the viewpoint of structural integrity assessment of components containing flaws such as corrosion pits in close proximity is discussed.
