For security concerns, the Civil Aviation Administration of China (CAAC) decided to suspend the operations of CRJ regional flights as of 0:00 yesterday, today's Youth Post reported.
The decision was made after the Bombardier CRJ-200 aircraft with the China Eastern Airlines crashed into a lake in Inner Mongolia shortly after taking off from Baotou last Sunday, killing all 47 passengers and six crew members aboard.
In most cases, it is impossible to suspend the operations of all the similar aircrafts just because of one accident, said a senior official with the CAAC. "Our decision aims at strengthening security inspection of aircrafts, and whether CRJ aircrafts will resume operation will depend on the results of our investigations," the official said.
Operations of five Bambardier aircrafts with the Shanghai Airlines and five with China Eastern Airlines have currently all be suspended, with the corresponding flights cancelled.
For the time being, no other aircrafts have yet replaced the Bambardier ones, most of which flying from Shanghai to Yunnan, Baotou, Yanji and Changzhi, according to local air-ticketing institutes.
