The current issue of Aviation News (HangKong Bao) displays a dozen manufactured J11Bs sitting at SAC without engines. This highlights the problem the PLAAF faces due to Shanyang Liming Aircraft Engine company's inability to fulfill all FWS10A (Taihang) orders. As indicted by the SAC's press release on its 2009 performance, it said it had fulfilled its PLAAF contracts "fairly" well. Which is different from previous press releases describing their performance as "very" well.*
Production certification delays prevented the FWS10A from entering mass production until recently. Perhaps this public display of engine-less fighters is SAC telling its partners to work faster.
