The Nagoya District Public Prosecutor's Office said Monday it has again opted not to indict four senior China Airlines officials over the April 1994 crash of an Airbus A300-600R at Nagoya airport that killed 264 passengers and crew members.

Prosecutors will not charge with professional negligence Chang Kuang-feng, 69, then the airline's vice president tasked with flight management; Hsu Chia-yin, 62, head of CAL's operations department; Lin Tzu-wen, 57, deputy head of the department; and Lin Yu, 57, chief pilot at the time.

The decision follows a reinvestigation prompted by the 11-member No. 2 Nagoya Committee for the Inquest of Prosecution in January 2000. The panel said an earlier decision not to indict the four was inappropriate.

As part of the renewed probe, prosecutors examined crew training procedures and evaluation methods used by Japan Air System Co., which introduced the same type of aircraft around the time of the accident.
