Shandong Airlines plans to dispose five Bombardier CRJ200 aircraft used on domestic services.
It attributed the decision to the rising maintenance cost of its aging fleet of CRJ200s, which on average are more than 11 years old, the carrier said in a Shenzhen Stock Exchange statement.
Shandong received its first CRJ200, with registration number B-3005, in October 2000. The fifth, with registration B-3009, was delivered in June 2001.
The airline adds that the disposal will also optimise its fleet structure and enhance fleet operational efficiency.
Flightglobal's Ascend Online database shows that Shandong Airlines operates a fleet of two Bombardier CRJ700 aircraft, and 55 Boeing 737-300s, -700s and -800s, in addition to the five CRJ200s.
