Abstract
Due to the great growth in passenger and cargo transportation, industry of Maintenance Repair
and Overhaul (MRO) of civil aircrafts has become one of the attractive industries. Safe
investment in different segments of this industry needs an analytical method. In this paper, we
introduce the new idea of combination the “value chain” and the “value shop” methods for
modeling MRO Industry. So all important engineering activities are considered and personal
costs are calculated for each activity. Finally, a new formula for calculating the value of each
activity is derived. As a case study, our analyses are applied to a company in Heavy
Maintenance segment of MRO, and they demonstrate that the “repair” activity is the most value
producing one that identifies the most value producing shops in this industry.

Introduction
The aircraft Maintenance, Repair and Overhaul (MRO) industry has a large and competitive
market. In 2005, the value of this market exceeded 100 billion dollars of which 52 billion dollars
belonged to the military aircraft market, and the remaining belonged to the civil, and cargo
aircraft market [1]. Value of the MRO market was even more than the value of aircraft
manufacturing (75 billion dollars) [1]. To succeed in this industry, one needs to have an analysis
of resources of the firm, to be able to formulate a resource-based strategy. Also, to formulate a
new strategy for a company active in the field of MRO, “Value Chain Analysis” can be used.
The result of this analysis is used in many different ways. First, it can be used to arrange for a
cost bench marking, and to optimize the cost structure of the company. Second, it is useful for
finding the key Success Factor (KSF) in different sections of the main or support activities, and
integrating KSF with an internal resource analysis result in strategic recommendations to achieve
competitive advantage in the selected activities. The third application goes to feasibility studies.
In this paper, we perform a market segmentation analysis along with the value chain analysis to
find profitability of each ring of the chain, which could later be used to recommend profitable
rings of activities for further development in the company. All these applications need to a
thorough and detail value chain analysis. Here, we develop a model for value chain analysis in
MRO industry and we will show how this model may be applied in a real scenario.
The value chain framework, which was introduced by Porter [2], is a reliable method for analysis
of the structure of value production in a specific firm. According to the three typology of
technologies mentioned by Thompson [3], there are three distinct value configurations that each
one is appropriate for one type of technology. These three typologies of technologies are: long-
linked, intensive and mediating. The value chain models the activities of the long-linked
3
technology, while the value shop models firms where value is created by mobilizing resources
and activities to resolve a particular customer problem, and the value network models firms that
create value by facilitating a network relationship with their customers using a mediating
technology [4].
Having considered the following three issues:
activities which is done in the aircraft MRO industry
the logic of producing the value
the technology type that is used in this industry,
we believe that the aircraft MRO industry is a combination of the industries that the logic of
producing value are modeled by both the value chain and value shop. Thus in order to
understand this logic, we will use both the value chain and value shop. In most of the value
chains, each activity has the specific structure of costs [5], which is needed to find.
In this paper, in addition to introduce the rate of regional and international development of this
industry, we try to show the chain of activities and the value chain that dominates on it. Also, we
examine this industry from the cost analysis point of view.
Introducing the Aircraft MRO Industry
Aircraft manufacturers beside their products, deliver a complete set of information and methods
of maintenance and repair of their products to clients [6]. Clients also have to consider all those
recommends regarding to the international organizations laws. These recommends are due to
developing flight quality, increasing flight safety and correctly using the products, prepared in
4
high standards and delivered to the aircraft owners. Thus, in addition to perform the flight
services, they are responsible for the maintenance and repair of their aircrafts. This responsibility
is carried out by the maintenance and repair engineering companies that they could be a part of
the airline itself the same as Lufthansa Technique and Air France or they could be an
independent company like Fars Co. and GAMCO. These engineering companies should perform
the interval checks which are defined by the manufacturers.
The two big and competitor manufacturers of aircrafts i.e. Boeing, Airbus and the other
manufacturers consider some regular checks for their productions that usually named as A, B, C
and D. The time of each check reaches after either a definite flight-hour or spending a definite
age of aircraft (The one that reaches earlier). The maintenance and repair phases for each family
of aircrafts (Boeing, Airbus …) are different. Among different checks, D check is a heavy one
and is called “Overhaul”. In this check, the aircraft grounded for long time and its entire
components are being inspected and if needed, become repaired. During the overhaul of a large
body aircraft, usually about 10 to 15 thousands activities are carried out. Thus, aircraft MRO
industry is defined as an industry in which all the regular checks mentioned by the aircraft
manufacturer, are done on the aircrafts.
Structure of the Aircraft MRO Industry
MRO industry is divided into five segments:
Engine
Airframe Heavy
Component
5
Line
Modifications
These segments are different with each other according to dependency to some factors such as
labor, parts repair, materials etc. For example, engine overhaul that has the most share of MRO
market, extremely depends on materials and on the other hand labor has the least effect on this
segment, but line maintenance is completely vice versa, i.e. materials has the least effect on this
segment and labor has the most. Table 1 contains the percentage of dependency of each segment
to the factors that was mentioned before.
Table 1: Structure of each segment based on cost producing factors [8, 9, 10]
Labor Materials Parts Repair Other
Engine 10 60 25 5
Airframe Heavy 70 20 10 0
Component 35 50 15 0
Line 80 20 0 0
In addition, this table shows that in each segment of the industry what the cost producing factors
are and how much their share is. For example, in Airframe Heavy segment, labor is both the
most effective and cost producing factor in that 70% of the costs is due to it.

International Aircraft MRO Industry Growth
Air fleet international growth has a direct effect on MRO industry. In fact, the capacity increase
of the air fleets enhances the aviation transportation market so this causes more needs to MRO
industry. Comparing the statistics of air fleets with the forecasting statistics for 2015 shows the
growth of demand for aircraft MRO. Table 2 contains this statistics for large body, narrow body
and regional jets for 2005 and 2015.
Table 2: Statistics of the aircraft types for 2005 and 2015 [11]

2015
Number 5489 14571 5696
Percent 21 57 22
Rate of Growth (Percent) 31 30 78
Table 2 shows a considerable growth in all types of aircrafts after 10 years, but the trend of the
market is to acquire the regional jets because the growth in this segment is much more than that
of the other segments. Moreover, these growths imply that the market of Aircraft MRO industry
will have brilliant changes. Table3 shows the share of five segments of the industry from the
total amount of 38.8 b$ market in 2005 and also indicates the percent of growth up to 2015.

Different regions of the world, based on their specialties and abilities in materials, technology
and labor have become dominant on some parts of the market. For example, Europe has achieved
the most part of the engine overhaul segment [14, 15] and Asia, due to inexpensive labors that is
the most effective factor in Airframe Heavy segment, has achieved the most share of this market
[15, 16, 17]. The share of different parts of the world from the total value of the market in 2005
is presented in table 4. In addition, the rates of growth for each part up to 2015 are also shown.

Middle East 1.552 4% 6.6%
Africa 0.776 2% 6.3%
Table 4 indicates that the growth rate in Middle East is very considerable and represents high
potential for investment in MRO industry. Whereas we need a good analysis to invest in this
industry, we use the method of value chain to figure out the different activities and their shares
on profitability. Therefore, we can suggest strategic proposals for this industry, but because of
the lack of information for all segments, this paper focuses just on Airframe Heavy segment and
does engineering analyses on this segment.
Method of Analysis
In addition to Porter’s value chain, C.B. Stabell et al. with considering to Thompson’s three
typologies of technologies, introduced two new methods for value analysis. Thompson divided
technologies to long-linked, intensive and mediating. Stabell believed that for industries that are
using the intensive and mediating technologies, it is better to use value shop and value network
9
configurations for value analysis, respectively. However, in the industries using long-linked
technologies, the value chain configuration is appropriate.
Value shop models the firms that supply and develop their sources and abilities in order to
resolve a particular customer problem. Therefore, their activities are related to problem finding,
problem solving, choice, execution and control/evaluation for customers’ special problem. If the
abovementioned procedure is applied but the solution of the problem is not satisfactory then this
procedure will be repeated cyclically. Hospitals, professional service firms, and educational
institutions are examples of firms that rely on an intensive technology. Therefore, value shop
configuration should be used for modeling them [4].
Value network models firms create value by facilitating a network relationship between their
customers using a mediating technology. Therefore, their activities are related to network
promotion and contract management, service provisioning and infrastructure operation. The logic
of activities and value producing are not the same as a chain or a cyclic issue but they are
simultaneous and parallel. Examples of companies that create value by facilitating exchange
among their customers are telephone, transportation and insurance companies and banks [4].
Porter defined value chain as the set of activities through which a product or service is created
and delivered to customers [18]. The value chain is a framework for identifying all these
activities and analyzing how they affect both a company’s costs and the value delivered to
buyers. Therefore, value chain models the firms in which value is created through transforming
the inputs to final products. In fact, in these firms, the productions are mediums for transmitting
the values from the firms to the customers. The most manufacturing companies and the factories
that convert the minerals to the materials useful for the different industries [19], are examples of
10
industries producing the value by successive activities. Usually, industries are divided to some
segments that each one can be analyzed by one of these three methods (value chain, value shop
and value network). Thus, the most firms cannot be purely analyzed by one method [4].
In this paper, based on some case studies, several active MRO companies are considered and all
working activities related to the overhaul of a B747 are identified. The criteria used to identify
these activities are as follows:
Considerable effect on value and distinction
Considerable share of cost
Same activities from the point of strategy and economic
Traditionally, to analyze the value chain, one considers the primary activities (inbound logistics,
operations, outbound logistics, marketing & sales and service) and support activities
(infrastructure, human resource management, technology management and procurement).
However, according to above criteria, we believe that the nature of major and value producing
activities is the chain of shop servicing that in each shop the value chain model cannot be used.
Instead, we should use the value shop model. Also, expertise investigations show that this chain
contains several engineering activities among the shops. Thus, the model used here is a
combination of both “value chain” and “value shop” models. The value of each activity is
estimated by a method introducing in the next part of this paper. We use the following criteria to
evaluate each activity:
11
Human resource costs
Type and amount of especial instruments
Type and amount of especial establishments
There are three major engineering aircraft MRO companies in Iran. They are FARSCO, HOMA
and SAHA. This investigation carried out in FARSCO and HOMA. These three companies cover
the engine, airframe heavy and line maintenance segment of this industry in Iran. Component
and modifications segments are outsourcing. FARSCO is specialized in airframe heavy. In this
research, we focused on realizing the successive activities and estimating the value chain of
airframe heavy segment.
In each industry for determining the value chain, one needs to separate the activities done on the
inputs unless they are transformed to the final products. These successive activities are called
“activity chain”. There is a value chain parallel with the activity chain that is determined
according to the criteria that are realized as the value producing criteria.
In order to model this industry as a chain of activities, we consider an aircraft, which needs
overhaul as the input material, and the aircraft that was repaired as the output production. For
segregating the activities, one should consider to the same order of them in volume or size. In
addition, these volumes or sizes should be in mediate size. If these sizes are very small then the
number of activities will increase and cause a long chain of activity. This makes the value
analysis hard and impossible. For example, for starting an overhaul on a B747, about 5000 word
cards (WC) are issued. These WCs are the essential primary activities that generate 1 or 1.5
times new activities which are called Discrepancy Records (DR). It is clear that such a detailed
chain of activities is neither needed nor useful. On the other hand, the segregated activities
12
should not be in large scale. The reason is that if they are so large then recognizing the activities
which have considerable value, becomes impossible. Therefore, this causes the loosing of
valuable activities. In the MRO industry, because of the competitive market and the need of
airlines to use their aircrafts as soon as possible, long time aircraft grounding does a large
amount of harm to the airline. Therefore, in general, all activities done on aircrafts have overlaps
with each other. Then, for realizing the segregated activities, one should consider that the start
and end of each activity is actually accompanied by the start and end of the other activities. Table
5 shows all activities which executed on an aircraft from the receiving up to delivering it. These
activities are distinguished for an overhaul (check D) and are general for any large aircraft.

For carrying out this procedure, different shops are involved. Generally, in such an engineering
maintenance company, the following shops exist: airframe and powerplant general (APG),
14
electronics & avionics (AVC), cleaning (CLN), fuel, paint shop (PS), sheet metal (SM), fiber
glass (FG), fabric shop (FS), welding shop, non destructive test (NDT), engineering shop (ENG),
quality control (QC), etc.
Introducing a New Method for Calculating Value Chain
Our method for value analysis is based on profit (value). Generally, profit is equal to subtraction
of costs from incomes. Here, we consider three basic costs as follow:
Human resource costs
Material costs
Overhead costs
Subtraction of all these costs from incomes of overhaul services creates the profit. This profit is
the result of performing all activities on an aircraft through the shops. Therefore, just it is
required to distribute this profit among all activities by a definite and logic method. For this
target, here, we introduce a method that is based on five steps. This method finally results in
distributing the profit to all activities by the proportional coefficients. These five steps are
explained below.
Step 1- Calculating the mean value of man-hours ( hmV )
For calculating hmV it is required to divide the profit to total man-hours of the MRO services on
an aircraft. Relation 1 shows how to calculate the mean value for each man-hour.
(1 )Total man-hours / Total value (profit)( = hmV )Mean value of a unit of man-hour
Step 2- Calculating the share of each shop from the total value (jsV )
15
For this target it is essential to find the share of each shop from the total man-hour of performing
MRO services. This information can be easily achieved from the division of “planning and
control of the production”. In this division, all the “work cards” and “discrepancy records” are
issued and documented. These two include a lot of information for each detailed activity such as
the required skill and the needed time or spent time for doing a specific activity.
Therefore, it is easily possible to estimate the total man-hour that each shop spent for carrying
out its specialized services on an aircraft. Multiplying the total spent man-hour of each shop by
the mean value of man-hour shows the share of the value, which is produced by each shop.
Step 3- Determining the share of each shop in performing each activity ( ijb )
For this target, it is essential to consider the MRO operation for each aircraft as a distinct project.
It leads to a work structure called “Project Base”. The advantage of this structure is that for each
project all the needs such as the following ones can be easily determined.
Defining the detailed activities that should be done on each aircraft
Determining which shops are required to be involved in each project
Determining the amount of man-day required that each shop should spent on each project
Thus, project base management for each aircraft causes to derive several useful data that the
most important one of them is the required man-day for each activity that performs by each shop.
This data leads to design a matrix, whose columns are based on shops and its rows are based on
activities. The numbers in the matrix are man-day and introduced by ijm . ijm means that amount
of man-days that shop j spent for activity i.
16
Here, for more clearance, we consider an MRO base which performs activities A, B and C
through circle (), square () and star () shops as an example and using this for explaining
the other steps. Table 6 shows ijm for our example.
Table 6: Matrix of activity chain-shop chain
Sum
90 40 -50 A
70 10 60 -B
100 80 -20 C
130 60 70 Sum
In table 6, for example, 50 means that for performing activity A, circle shop should spent 50
man-day, and 90 means the total man-day which is needed for finishing activity A. 130 means
that the total man-day that star shop spends for its professional MRO service for a project. In
addition, the other numbers have the same meanings.
If each ijm divided by the sum of them in the last column and then multiplied by 100, then the
share of each shop in carrying out a special activity will be achieved. These coefficients are
calculated through formula 2 and are called ijb . The share of each shop for our example is shown
in Table 7.

Where i and j are counters for activities and shops respectively. It means that for each activity, i
is constant and for each shop, j is constant.
Table 7: Share of each shop for carrying out each activity
Sum
100 45 -55 A
100 14 86 -B
100 80 -20 C
For example, this table shows that 55% of activity A is done by circle shop and the 45% left is
done by the star shop.
Step 4- Normalize the share of each shop with respect to column
In order to normalize the shop share for each activity, each ijb should be divided to column
summation in the last row of table 7. Normalization causes equality between the total value with
the sum of value of each activity. These coefficients are very important. The reason is that
through these coefficients the total value of each shop is distributed among the activities. These
coefficients are calculated by formula 3 and called ijc . For our example, ijc are shown in Table
8.

Considering step 1 to 4 and their explanations, we are now able to calculate the value of each
activity through formula 4.

Calculating Value Chain for Airframe Heavy Segment of MRO Industry
Initially our target of doing this investigation was to become familiar with the value chain of the
total MRO industry. However, at the beginning of the research, we encounter with 2 kinds of
problems that each one imposes some limitations. The first problem was the dependency of
motor, component and modifications segments to abroad resources. Therefore, our field of study
was limited to the air frame heavy segment. The second problem was the data that were
19
inaccessible for us but we strongly needed them. This problem had such strong effects on our
study that leads us to consider just “operation” ring of value chain.
For calculating the value chain for this segment of MRO industry, the introduced method in the
previous section of this paper is used. In addition, as it is mentioned, the MRO process is divided
to 14 activities, which are carried out by 12 professional shops. For calculation, the real
information of Fajrashian Aviation Repair/Overhaul Services Co. (FARS Co.) is used but here,
relative amount of jsV in Table 9, ijb and ijc coefficients in Tables 10 and 11 and relative amount
of iaV in Table 12 are presented. In fact, these tables are the results of steps 2 to 5.

Conclusion
Using the innovative model of combination of the “Value Chain” and the “Value Shop”, all the
essential and technological activities related to the Airframe Heavy Segment of aircraft MRO
industry were understand and reduced to 14 activities. All these activities are carried out through
12 shops. Here, three different sources of costs are considered and subtracted from the total
income. Therefore, the profit was calculated. For calculating the value chain, it is required to
distribute the profit to the activities. For this target, a method based on 5 steps are introduced.
Finally, the results of this study are determined as follows:
Derive a method for calculating the value chain
Separating the valuable activities from the invaluable activities
Determining the share of each shop for carrying out each activity
The most valuable activities are “Repair”, “Opening & Removal” and “Technical
inspection”
The least valuable activity is “Flight tests and aircraft delivery”
Among all shops, “APG”, “SM” and “AVC” have the most share of value producing
In order to modify this study, it is required to avoid some simplifying assumptions for calculating
the costs. Also, using the same mean value of man-hour for all shops leads to disappearing of
some differentiations of activities. Therefore, this makes some misjudgments.
Moreover, to develop this study, it is necessary to do a feasibility study for the sake of
establishment a new MRO base. The result of this study, beside the result of value analysis, will
24
help the investors to become familiar with the costs and values. Therefore, they can easily
reduce the risks of investment. For example, this study shows (without considering the feasibility
study) that for entrance in the field of Airframe Heavy segment of MRO industry, an investor
can safely invest on APG, AVC and QC shops and just services the “Repair”, “Opening &
Removal” and “Technical inspection” activities and outsources the other activities.
