Aviation-incident data from the Aviation Safety Network showed that Sriwijaya Air has had four other mishaps with the Boeing 737 since 2008, resulting in one death and a total loss of each plane. The airline was only recently removed from the European Union's list of banned air carriers, a designation typically given to airlines believed by the group of countries to be unsafe, in 2018 after an 11-year tenure that began in June 2007.
Though all incidents involve the Boeing 737, the aircraft isn't inherently dangerous (recent troubles with 737 Max notwithstanding). The Dash 500 variant that crashed on Saturday had had a good safety record since its introduction in 1987.
