Safety climate of aircraft maintenance personnel in Nigeria

Abstract

This study used a safety climate questionnaire adapted from Commercial Aviation Safety Survey (CASS) as data
collection instrument to investigate safety climate factors of aircraft maintenance personnel in Nigeria aviation
industry. The CASS questionnaire was modified to accommodate the peculiarities of the safety climate in maintenance
repair and overhaul organization (MRO)using four main factors and twelve sub factors. Multiple regression model
was used as tool to analyse the data on safety climate of aircraft maintenance personnel. In the first case scenario,
the multiple regression results using error tendency against the linear combination of the safety climate factors
indicated that the equation containing the 15 variables accounted for 41.2 percent of the variations in error tendency
in aircraft maintenance in MRO personnel that is significant at the 5 percent level. In the second case scenario, the
multiple regression results using error tendency against the linear combination of the 7 safety climate factors
indicated that the factors accounted for about 27.3 percent of the variations in error tendency in aircraft maintenance.
It is recommended that focus should be shifted by management to response and feedback on reported safety issues,
safety fundamentals, reward system, employee empowerment, and management involvement that are unfavorable in
ranking in this study. This shift in focus is expected to drive relevant and necessary changes that can help improve
safety with the MROs.
