Civil Aviation Administration of China

Fortunately for Chinese passengers, aged Boeing 737s have drawn the attention of the CAAC. (These are the types of planes which demonstrated fatigue when a hole blew in the fuselage of a Southwest Airlines Boeing 737 on April 1.) Planes with 35,000 total flight cycles or more will be inspected within 4 days; and those with between 30,000 and 35,000 will be inspected within twenty days. The CAAC says that most of the Boeings are new.
