A Gap Analysis on Implementation of Safety Management System in Airport: A Case Study

The aviation industry in Indonesia is considered flourishing as the national airline industries are expected to grow and develop well in the future, according to the Ministry of Industry. This condition has resulted in increasingly dense schedules of departure and arrival of aircraft at the airport. Improved aircraft flight schedule will be directly proportional to the increase in the risk of the accident flights and serious incidents. To prevent the associated risk, there are standards that must be met to be able to carry out the flight activities safely. The International Civil Aviation Organization has set the airport safety management system (SMS) as a mandatory standard for airline industries. This research aims to investigate the implementation of the SMS, i.e., safety management manual (Doc 9859). A gap analysis is performed to compare the standard with the observed phenomena. The case study was conducted in Adisumarmo International Airport which is located in Boyolali, Central Java Province. The results show that there are indeed gaps in the implementation of the standard. The fault tree analysis and barrier analysis are then employed to identify the cause of failure.
