Considering the key role of the aviation industry in maintaining and promoting safety, efficiency and legality in air transportation, this industry has a special place in the economic and social dynamics of society; Therefore, the key role of maintenance and repair software in the aviation industry, repair and maintenance of parts, timely supply of equipment and their reliability is considered a strategic priority for the senior managers of these industries.
The effect of Iran's regional and international conditions on the importance of maintenance and repairs of aviation industries
Iran’s regional and international conditions in the world have made the aviation industry one of the vital and strategic industries of the country. Considering the importance of maintenance and repairs in the aviation industry, which is one of the main processes of the country’s airfields, and also considering that Iran is under sanctions and the possibility of buying new planes (in the military and civilian fields) and more They do not exist for the fleets and air industry of the country, and on the other hand, due to Iran’s position in the region and the hidden and open threats of the enemies, it obliges the country to maintain the readiness of all defense forces. This means that all equipment, machines and facilities (especially military aircraft which are considered as the first defense factor of any country) should be in full readiness. Based on the information stated above, it can be concluded that the issue of maintenance and repairs in the aviation industry, which includes about 15 to 60 percent of the total costs of the organization, is of great importance and sensitivity.
The importance of maintenance and emergency repairs in the aviation industry
In the aircraft industry, maintenance and repairs are planned and unplanned.
A common belief among aeronautical engineers is that they do maintenance planning so that there is no need for maintenance planning, but in the real world, anything can happen. And the plane needs emergency repairs when it is not planned, in other words, the repairs are out of the plan. According to the report of airlines, it has been determined that about 90% of maintenance and repair works are unplanned, technologically, aircraft maintenance and repairs include the level of light, semi-heavy and heavy repairs or overhaul.
Fix it after it's broken, but consciously
From overhaul to aircraft design and construction
Due to the fact that overhaul and assembly are related to each other and the experiences of each sector can be used for other sectors, therefore every country that has the ability to overhaul the aircraft has the ability to assemble it as well. The net costs of the plane during its life are 2 to 3 times the price of the plane. Therefore, the ability of airlines and countries to reduce costs plays a significant role in the profitability of the aviation industry. Having the ability to maintain and repair as a level of technology is a prelude to obtaining higher levels such as designing and building aircraft.
If a country has the ability to repair, it can enter the field of construction and achieve success in this field as well. In the last decade, the development of the aviation industry has shown radical economic growth. Similarly, passenger demand is currently flourishing, showing an increase of 5.2 percent from 2012 to 2013 and reaching 31 percent in 2017 (ICAO 2014). Researches and statistics indicate that the aviation industry is facing international markets worth about 3600 billion dollars and it is predicted that these markets will reach 5570 billion dollars by 2034; Researches also show that today the international market for repairs and maintenance is equal to 10.7 billion dollars, which means a great opportunity for the country in order to optimally allocate resources and benefits from it, but in addition to the opportunities provided for the country For example, research results show that due to sanctions in recent years, only 168 out of 257 air fleets in the country have the ability to provide services to users. These statistics indicate the importance of the aviation industry.
Maintenance and repairs are one of the basic concepts in advanced organizations moving towards world class, which has a special place at the level of managers, especially senior managers and employees of the organization. Correct scientific and planned maintenance and repairs with modern methods directly affect productivity, product quality, direct production costs, equipment reliability and profitability.
Planning in net affairs is not necessarily in the direction of net preventive It also includes non-urgent corrective repairs
Economy and security dependent on maintenance and repairs
Maintenance and repairs have been defined as a set of activities whose purpose is to maintain or prepare a device so that it can perform its tasks completely. According to this definition, the activities include performing public services, periodic inspections, continuous control of the conditions of major repairs and preventive replacements. Since this industry is subject to continuous changes and developments and requires a lot of investment, also because maintaining the maintenance and repairs of the aircraft causes many benefits, including regional development, national security and related innovations, and as a result, it causes The economic development of the country doubles the importance of this issue. A maintenance strategy defines an organization’s vision of how to maintain the health and safety of assets throughout their life cycle. As a result, maintenance and repair strategies include the following;
Corrective maintenance and repair is a corrective action to restore equipment and machines to their working condition after the equipment has stopped unexpectedly, this action includes repairing or replacing failed parts, which can be done if needed. This strategy can lead to peripheral equipment failure, long repair times, machine safety and environmental hazards; Therefore, investing in maintenance and corrective repairs is much less than other strategies;
Preventive maintenance and repairs: A process based on intervals over a suitable period of time. This strategy is implemented on operational equipment to prevent any possible failure or severe degradation that may affect the reliability of the equipment in the future. As a result, the goal of this strategy can be called increasing efficiency, equipment reliability, reducing emergency stops and preventing depreciation.
Maintenance and repairs based on reliability: this strategy is a process that identifies and determines the different maintenance needs of equipment and machines in different working conditions so that each of these equipments can perform their main tasks in the best possible way, maintain and Reliability-based repairs, on the one hand, determine what needs to be done to extend the life of any physical assets, and on the other hand, this strategy specifies and operationalizes the expectations that users have from the equipment. Without PM, operation and breakdown, reliability and repairs are reduced. This process is done by finding critical machines and analyzing failure modes and their effects (FMEA), analyzing factors affecting reliability and analyzing the effects of a machine failure in the entire factory.
Predictive maintenance and repairs: It is a process and technique that uses the tools and methods of monitoring organizational conditions to track the performance of equipment during normal and daily activities, find possible defects and fix them before failure and fix the defect; In other words, this strategy provides an opportunity to react and repair the equipment before the damage progresses so that the operation of the equipment is completely lost. Finally, the failure rate and costs are reduced.
Comprehensive productive maintenance: It is a strategic approach that improves maintenance activities in the organization and creates focus and participation of all employees in the organization. Applying this strategy in organizations increases production effectiveness, improves performance and reduces costs. Today, despite the intense commercial competition in the world, maybe Total Productive Maintenance or (TPM) is the only key to the success of maintenance and repairs of winning companies.
Key factors affecting the future maintenance and repairs of Iran's aviation industry
In order to prevent breakdowns, we need future research and analysis of data collected during previous repairs and other operations. This factor reduces the number of checks over time, increases the accessibility of the aircraft, and ultimately reduces maintenance costs, as well as using the type of aircraft, the condition of the aircraft, maintenance capacity, and other operational limitations are considered to optimize the program. Controlling long-term maintenance and repairs for air fleets and minimizing the waste interval between checks. The researchers in this study came to the conclusion that, on the one hand, by using this method, compared to the current routine, the number of returned checks can be reduced by about 7% over four years, while the calculation time is less than fifteen minutes; And on the other hand, this can lead to savings of $1.1 million in maintenance and repair costs for fleets, as well as generating more than $9.8 million in revenue due to increased aircraft availability. Research researchers have summarized the key factors and driving forces affecting the future of maintenance and repairs of Iran’s aviation industry in the following cases.
The researchers explained the compatible scenarios for the future maintenance and repairs of the aviation industry in Iran using the ScenarioWizard software. By analyzing the mutual effect, they analyzed the overall influence and effectiveness of each factor and concluded that there is no factor in the above cases that is free from any influence and influence, which is the most likely scenario, the increase of sanctioning factors and the greater dependence of industries on knowledge-based technology and The interior of the country predicts; Therefore, this industry should pay serious attention to improving the situation of these factors, and measures such as facilitating the conditions for creating new technical departments with modern technology, including the use of local maintenance and repair software, paying attention to the knowledge-based capacity in the country can play a significant role. to improve these factors.
The aviation industry should identify specialized and efficient employees and have plans to improve their skills and performance. In this scenario, the aviation industry should plan and formulate a suitable knowledge management strategy at the organization level, implement local and reliable maintenance and repair systems, improve the research and development capabilities of advanced maintenance and repairs for the production and repair departments in order to Manage crises that may arise in the future. The strategy emphasizes the health and safety of equipment and machinery and reducing employee mistakes, both intentional and unintentional, and in general, maintenance and repairs should prevent sudden accidents as an influential factor in the aviation industry.
Technology makes an efficient activity more efficient and an inefficient technology more inefficient, so before using technology, optimize your processes and before that your mind
According to the studies conducted at the Air and Sea Development Center in Pennsylvania, which was conducted on the hydraulic pumps of the aircraft, it was concluded that a 66% improvement in filtration caused a 4-fold improvement and a 93% improvement in filtration caused a 13-fold increase in the life of the mentioned pumps.
A DC-8 airplane required 4 million hours of structural inspection for 20,000 flight hours, meaning that every hour of flight this bird would have required about 200 hours of structural inspection in the 1950’s conventional thinking, but the Boeing 747 was produced, it was a gigantic, double-decker airplane. that this strategy was not the answer for its inspection, after holding meetings among the experts, those who were familiar with repairs and systems, they will discuss the necessity of implementing the new system of maintenance and repairs, and during the repair period, the technical content and priorities and … revision was done. As a result, the Boink 747 inspection reached 66,000 hours, which required 3.3 hours of inspection per hour of flight. The DC-8 had about 339 overhauls, compared to 10 on the DC-10.
