The airline industry relies on the implementation of Safety Management System (SMS) to integrate Safety policies and augment safety performance at both organizational and individual levels. Although there are various degrees of SMS implementation in practice, a comprehensive scale measuring the essential dimensions of SMS is still lacking. This paper thus aims to develop an SMS measurement scale from the perspective of aviation experts and airline managers to evaluate the performance of company’s Safety management system, by adopting Schwab’s (1980) three-stage scale development procedure. The results reveal a Qive-factor structure consisting of 23 items. The Qive factors include documentation and commands, safety promotion and training, executive management commitment, emergency preparedness and response plan and safety management policy. The implications of this SMS evaluation scale for practitioners and future research are discussed.
