INTRODUCTION
Currently, most aviation manufacturing enterprises
use a domestic method of organizing the maintenance
and repair of aircraft and aircraft engines. This is a
waste of time at meetings, conferences, reviews and
discussions when making any decisions on the tasks of
maintenance and repair of aircraft. Naturally, this is a
waste of 20% to 40% of useful time, as a result of which
the duration of the maintenance or repair cycle
increases and leads to a constant increase in the cost
of the MRO service. Domestic and international

practice of many aviation enterprises shows that there
is an intensive struggle to reduce MRO costs to
improve the efficiency of aircraft operation. The main
goal of the dissertation research is the activity of the
applicant aimed at developing and improving their
abilities, increasing the efficiency of using aircraft and
ensuring flight safety, significantly related to the state
of the functional systems of aircraft, increasing the
requirements for safety and regularity of flights,
increasing the costs of their maintenance and repair,
which requires searching for and implementing new
effective methods of technological processes for the
maintenance of aircraft equipment. In this regard, the
topic of the dissertation is relevant for the operation of
civil aviation and has practical significance for
increasing
the
competitiveness
of
domestic
enterprises.
METHODOLOGY
The complex of maintenance activities defined by the
aircraft
maintenance
and
repair
system
is
conventionally divided into two groups:
1) scheduled preventive maintenance work related to
the prevention of failures and malfunctions;
2) additional work aimed at restoring the operational
condition of the aircraft in the event of a failure or
malfunction.
The main requirement for the maintenance process as
a whole is to ensure the readiness of the aircraft to
perform its main functions with the least cost.
The use of modern information technologies allows
achieving increased efficiency of maintenance and
repair at enterprises. Having this information, the
enterprise management has the opportunity to
purposefully work to increase productivity, reduce
production losses and strictly control the efficiency of
using financial resources invested in improving
production efficiency.
Today, more and more companies are joining the fight
to improve their operational efficiency, and they have
enormous growth potential in this area.
Each airline has production workshops and
departments or divisions servicing aircraft and its
components of Western or Eastern production.
The Republic of Uzbekistan has unique potential for
the use and repair of modern aviation equipment of
Central Asia. The aviation industry plays an important
role in integrating Uzbekistan, which is located far
from sea routes, into the global community, so the
reforms being carried out in the industry are very
important. The laws of most states allow air transport
operations only if all aviation products comply with the
requirements of the International Civil Aviation
Organization (ICAO).
For example, Uzbekistan Airways Techinics LLC is a
structural division of Uzbekistan Airways JSC and has
100 years of experience in the field of maintenance and
repair (MRO) of aircraft, engines and components. The
modern complex of UAT LLC performs MRO of aircraft
and
their
components,
such
as
Boeing
737/747/757/767/787, Airbus 300/310/318/319/320/321.
With the acquisition of Western-made equipment by
Uzbekistan Airways JSC, there was a need to master
their maintenance, and in 1997, a center for the
maintenance of Western-made aircraft was created on
the basis of the plant. Already in 1998, the first C-check
was performed in Central Asia on one of the Airbus 310
aircraft. Since 1999, C-check maintenance has been
performed on Boeing 767 and BAe146/AVRO146-RJ
aircraft, and since 2000 - on Boeing 757 aircraft.

The functions of the maintenance center (MC) of
Western-made aircraft (WMA) are to perform
maintenance of WMA, maintenance and repair of
WMA components in the scope of the approved scope
of activity. Ensure prompt and high-quality elimination
of defects identified during the performance of WMA
maintenance and repair of KZP. Maintain the quality
system in working order as a means of ensuring that
the functions performed during the repair and
maintenance of aircraft comply with the requirements
established by the "Quality Manual".
Development of models and algorithms for decision-
making in the tasks of aircraft maintenance and repair
based on the use of information technologies is one of
the initial stages of aircraft maintenance and repair
optimization. A necessary condition for organizing the
use of information technologies at an aviation
manufacturing enterprise is the creation of a single
information space (complex), with the help of which all
automated control systems of an aviation enterprise,
as well as departments, workshops and divisions can
quickly and promptly exchange information. One of
the most important conditions for the implementation
of an automated control system for organizing work
on aircraft maintenance and repair (digital production)
using information technologies (model and algorithm
for decision-making) is the functionality that will allow
automatic collection of data on the work performed by
all production facilities (aircraft, ground equipment,
tools, workplaces of enterprise employees, supply
(provision of spare parts and consumables), auxiliary
service departments, departments, laboratories, etc.)
into a single information space (comprehensive
database),
for
the
purpose
of
operational
management of production during maintenance and
repair of aircraft in an aviation enterprise.
An example of such functionality is a smart system for
monitoring maintenance and repair work, which allows
monitoring the work of production personnel in real
time, classifying and analyzing their work, conducting
operational dispatching of workshop and service
departments, transmitting information to the
information space (complex database), issuing
reporting information, interacting with production
planning and management systems. The main object
for the automated management system of an aviation
enterprise is an aircraft. This should be the starting
point in the implementation of a new production
planning and management program. First of all, the
corresponding automation of processes should be
carried out in this direction.
There are many factors that influence the choice of the
optimal strategy option for aircraft maintenance,
namely failures or defects that are detected during the
defect detection process, is the ability to perform its
functional potential in due quality and volume. The
purpose of the strategy of this system is to prevent
significant time losses for other work and minimize
costs, reduce the cost of the serviced aircraft, and
ensure reliability and high-quality performance of
aircraft maintenance and repair work. To do this, it will
be necessary to take into account all service services,
departments, workshops and auxiliary services, as well
as the entire work process associated with aircraft
maintenance.
For integrated management of maintenance, repair
work, costs, inventory control and purchases of spare
parts, more common software products have been
created and developed.
Aviation enterprises need to create low-cost products,
which requires increasingly rapid development and
implementation of various methods, devices and
systems, while the intellectual level of software is of

great importance. At the same time, one of the main
requirements for software is the ability to quickly and
in real time evaluate output data and obtain analytical
results. Based on the analysis, we carry out automated
data collection on the values of physical parameters at
specified points of the object under study, as well as
primary data processing, data collection and
transmission, and their interaction. It is proposed to
develop a model and algorithm for aircraft
maintenance and the use of information technology.
CONCLUSION
In conclusion, the benefits, advantages and
advantages of using software (product) for planning
and managing all processes of work during
maintenance or repair of Western-made aircraft. The
use of such software in aircraft maintenance can have
several useful effects:
Increased efficiency
. It helps to quickly determine
what types of work will be performed, what tools are
required, what equipment needs maintenance or
repair, which ensures faster and better performance of
these works. This reduces time, downtime and
increases productivity.
Process optimization
. It helps to optimize the
maintenance or repair process, which reduces the cost
of these works and increases the efficiency of the
process.
Improved safety
. It helps to monitor the condition of
the equipment and quickly respond to any possible
problems. This increases the safety of work on
different equipment, at different altitudes and reduces
the risk of accidents.
Reduced workload on personnel
. Software can make
maintenance or repair work more efficient, which
reduces the number of personnel required and reduces
the cost of their maintenance.
Improved service quality
. The software helps to
quickly determine what types of work should be
performed and on the basis of what documentation
and will help to identify and find possible problems
with equipment and tools and take measures to
eliminate them. This allows to improve the quality of
service and increase customer satisfaction.
