Research design and methodology

This paper is a part of a research work about Brazilian Aeronautical Maintenance Companies.

The starting point has been a data collecting during two years (2009–2010). Data was

collected through the National Civil Aviation Agency (ANAC) database. Methodology used

based on the research terminology of Yin (1994) has been exploratory and descriptive based

on a case study with both qualitative and quantitative approach. Exploratory studies are

appropriate when the research problem is difficult to delimit, the problem is not well known

and the available knowledge is not absolute (Yin, 2001). It was used additional methods of

data collection to triangulate the data obtained from the ANAC database like ANAC

regulations, specialized internet sites and literature review.

The purpose of this study is to expand knowledge about the aircraft maintenance industry in

Brazil in order to gain a better understanding about the technical distribution of the Brazilian

niches of capability, as well as identifies the profile of the certification cluster according to

the technical domain of certification.

For achieving that purpose a exploratory study about the Brazilian Aircraft Maintenance

Industry will be developed be developed by analyzing already established and known facts on

a new perspective that permits to have a comprehensive understanding the Brazilian Aircraft

Maintenance Industry.

3.1. Combined Certifications

The number of combined certifications (companies that possesses two certifications

simultaneously) regarding to different classes and patterns of certifications are shown in Table

2. Diagonally it is possible to note the absolute total of certifications for each class and pattern

and also the number of companies certified in more than one class and pattern of certificate

are shown combining lines and columns.
