Throughout the 1990s, the airline employed many ex-ROC Air Force pilots. Due to the company's poor safety record in the 1990s, China Airlines began to change its pilot recruitment practices and the company began to actively recruit civilian-trained pilots with proven track records. In addition, the company began recruiting university graduates as trainees in its own pilot training program. The company also modified its maintenance and operational procedures. These decisions were instrumental in the company's improved safety record, culminating in the company's recognition by the IATA Operational Safety Audit (IOSA).
