**Aircraft Maintenance Engineers Questionnaire**

Dear Participant,

The aim of this study is to explore the contributory factors to aircraft maintenance-related accidents and serious incidents in Nigeria in order to achieve a deeper understanding to this safety critical aspect of the aviation industry.

To achieve this aim, one of the objectives was to qualitatively analyse the accident investigation reports published by the Accident Investigation Bureau in the last 10 years.

This was achieved by using Insley's (2018) Maintenance Factors Analysis and Classification System (MxFACS) taxonomy to code the accidents and Hieminga's (2018) taxonomy to code the serious incidents. The results of the analysis showed that the aircraft maintenance-related accidents were attributed to the

following contributory factors listed in alphabetical order.


This questionnaire is designed for Aircraft Maintenance Engineers (AME) in Nigeria to identify root cause of study findings the output of the data analysis.

Q1 Are you an aircraft maintenance engineer?

Q2 How many years of experience do you have in the aircraft maintenance industry in Nigeria?

Q3 From your experience and in your view, which of the following contributory factors to maintenance related accidents are more likely to cause future accidents? Where (one) 1 indicates least likely and (seven) 7 indicates most likely
