MU5735 Crash Report Sheds Little Light on March Disaster

(Bloomberg) — Chinese authorities said they need more time to figure out what caused a China Eastern Airlines Corp. jet to plunge into a hillside March 21, killing all 132 passengers and crew.

The two black boxes from the Boeing Co. 737-800 NG aircraft were badly damaged in the crash in southern China, and analysis of them is ongoing, the official Xinhua News Agency said, citing a preliminary investigation report from the Civil Aviation Administration of China. The crew and maintenance staff involved all met qualification requirements, it said.
