What’s delaying Long March 5? Bob Zimmerman, BehindtheBlack.com

The new colonial movement: Though the details are vague, a Chinese official said earlier this week that they now expect to resume launches of their Long March 5 rocket in 2018.

The article says that the July launch failure of the second Long March 5 was due to “a manufacturing defect affecting one of two YF-77 engines powering the first stage. If officially confirmed, this would mean no major effects such as redesign are required, meaning a relatively swift return to flight.”

The long delay since July however suggests to me that the defect was more serious, and has either required that redesign or a complete recall of all YF-77 engines.
