Maintenance Process

In aircraft operation, maintenance must always be carried out so that the aircraft meets airworthiness standards in order to meet flight safety, in which maintenance is carried out on aircraft components on a regular basis. The problem that exists today is that there is frequent damage to the aircraft without any known cause, even when the aircraft is flown which results in the plane crashing and experiencing severe damage until it can no longer be used. This condition is due to the absence of a system that can monitor the aircraft maintenance process, so that the components of the aircraft used to be flown cannot be known whether it is airworthy or not. The solution to overcome this problem is by building a website-based system. The system was built using the CodeIgniter framework and PostgreSQL as its database. Meanwhile, for system development using the Prototype method. Through this system the aircraft maintenance process can be carried out according to the existing schedule.

This article is dealing with airline industry standards regarding reliability reporting and with practical aspects of reliability program deployment within an operator’s organization. Reliability program is a tool for monitoring the effectiveness of aircraft maintenance program. Apart from being an effective tool for maintenance program development, the reliability program can bring to light flaws in aircraft design, discrepant operational procedures, discrepancies in line and base maintenance. Reliability program is also considered to provide very valuable means for achieving better operational performance (through decreased maintenance-related problems in operation) and increased flight safety. For this reason, reliability programs are mandated by the regulations for all commercial operators. Even though there is a general industry standard regarding maintenance reliability programs, it still has to be customized and optimized by each operator in order to gain the most out of it. Organizational procedures will vary significantly from one operator to another, reflecting the size and structure of the monitored fleet, size of the operator and its engineering power. As maintenance reliability program involves the application of statistic methods in finding systematic negative trends, the bigger the size of the fleet, the more accurate and reliable results can be achieved. This work is outlining the existing airline industry standards and good practice in carrying out maintenance reliability program. KEY WORDS: aircraft maintenance program, maintenance reliability program, flight safety, small airline operator

Maintenance Process

Shiftwork disrupts the sleep-wake cycle, leading to sleepiness, fatigue, and performance impairment, with implications for occupational health and safety. Aircraft maintenance crews work a 24-hour shift rotation and sustain flight punctuality rate of job stress.If an error occurs during the aircraft maintenance process, this error may become a potential risk factor for flight safety.This paper focuses on optimal work shift scheduling to reduce the fatigue of aircraft maintenance crews. We model fatigue as a dynamic system, and the objective is to find the optimal shift schedules that minimize the maximum fatigue values. Various constraints such as holidays, company and government regulations are included in our model. This optimization problem is formulated as a mixed-integer program, in which the shift assignments are described by 0-1 variables. We take a sample aircraft maintenance crews schedule to demonstrate the proposed methods.

Remaining-useful-life prognostics for aircraft components are central for efficient and robust aircraft maintenance. In this paper, we propose an end-to-end approach to obtain online, model-based remaining-useful-life prognostics by learning from clusters of components with similar degradation trends. Time-series degradation measurements are first clustered using dynamic time-warping. For each cluster, a degradation model and a corresponding failure threshold are proposed. These cluster-specific degradation models, together with a particle filtering algorithm, are further used to obtain online remaining-useful-life prognostics. As a case study, we consider the operational data of several cooling units originating from a fleet of aircraft. The cooling units are clustered based on their degradation trends and remaining-useful-life prognostics are obtained in an online manner. In general, this approach provides support for intelligent aircraft maintenance where the analysis of cluster-specific component degradation models is integrated into the predictive maintenance process.

Maintenance staff fatigue is one of the key factors contributing to the occurrence of errors in the maintenance. The problem of maintenance staff fatigue is a serious challenge for aircraft maintenance organizations, and its solution is directly related to the impact on flight safety. The authors consider the issues of the fatigue effect on the maintenance staff performance and related consequences. The article provides the results of the maintenance staff fatigue research, obtained through a survey of one of the organizations` employees. According to the survey, errors are the most likely outcome of work in a state of fatigue in aircraft maintenance. The obtained results made it necessary to develop a methodology for managing maintenance staff fatigue in aircraft maintenance. The methodology is based on a questionnaire, where the respondents are asked to answer questions regarding their state of fatigue, and fatigue assessment criteria. The assessment results make it possible to develop the necessary corrective and preventive measures, including the privilege limitation and suspension to perform maintenance tasks.

A Company

PT. GMF Aeroasia, Tbk is a company engaged in aircraft maintenance services. The aircraft maintenance lead time is regulated according to the agreement set forth in the agreement in the form of a work order, when the maintenance process takes place there is almost always a delay when working on the aircraft, both in terms of physical work or delivery of documents. These problems are several forms of waste, where waste is any activity that does not provide added value. Therefore, the purpose of this study is to identify the type of waste and determine the factors that cause waste in the delivery process of aircraft c-check maintenance documents. The method used in this study used a fishbone chart, cause failure mode effect, failure mode and effects analysis and problem identification and corrective action. Fishbone chart and cause failure mode effect are used to find waste that causes delay in document delivery, then analyzed using failure mode and effects analysis, three causes of the highest delay were found, namely stamps on incomplete documents (RPN 16), waiting for customer approval (RPN 16) and material certificates not available (RPN 12). Corrective Action was prepared as a recommendation to improve the delivery process for aircraft c-check maintenance documents. By knowing the types of waste and the factors causing waste in the delivery process of aircraft c-check maintenance documents at PT. GMF Aeroasia Tbk is expected to reduce waste and fulfill customer satisfaction. Keywords: Lead Time, Waste, Delay Delivery of Documents, Cause Failure Mode Effect Method, Corrective Action

Maintenance Process

In the 2016 EASA Annual Safety Report, 1318 incidents were categorised as involving a safety issue related to aircraft maintenance. All the Key Risk Areas, or most frequent outcomes, for aircraft maintenance as a safety issue were shown to be related but associated Rulemaking Tasks have not yet appeared in the 2017-2021 European Plan for Aviation Safety. Categorising EU-wide incident reports appears to be difficult due to the use and construction of the ‘Event Types’, or contributing causes, taxonomy used in the reporting tool. Previously developed taxonomies are either limited in the number of categories due to limited information in reports, or they are aimed more at an investigation than straight reporting. As a result, these taxonomies are not suited for use in a reporting tool, and these taxonomies lack the detail for focused feedback to the maintenance industry. Thus, a two-level taxonomy has been developed within this study, using a high-level overview of the maintenance process as a basis for the first level and a variation of descriptions, both specific and more broad-spectrum, for the second level. A set of 3910 incident reports from the central repository were analysed, causing 2677 incidents to be excluded for a variety of reasons such as a lack of information (the narrative was empty in 1100 reports or 28%), or the use of a language other than English (814 incidents, 21%). The remaining 1232 incident reports were categorised using the new taxonomy. Of these, 361 incidents occurred during installation of components (29%) and 308 incidents were related to maintenance control (25%). The increased level of detail from the new taxonomy allows for identification of procedure types that are more susceptible to errors, such as installing or removing components or deferral of a defect so that an aircraft can be dispatched. This will hopefully lead to increased vigilance as well as further measures to increase safety.
