Investigating agency: JTSB
Narrative:
A Bombardier Global 6000, operated by Silver Air Corp., took off from Tokyo International Airport as a charter flight. While the aircraft was flying at FL400 to Tan Son Nhat International Airport, Vietnam, the instruments indicated a loss of cabin pressurization. The flight crew declared an emergency and made an emergency descent until the aircraft reached an altitude of approximately 10,000 ft. The Pilot in Command changed its destination to Naha Airport and the aircraft landed at Naha Airport at 18:32.

PROBABLE CAUSES
The JTSB concludes that the probable cause of this serious incident was the shutdown of both PACKs of the Aircraft during the flight at FL400, which resulted in loss of cabin pressurization.
Concerning the shutdown of both PACKs, it is highly probable that the flight crew member was going to operate the switches of fuel recirculation system but erroneously pushed both PACK switches to position “OFF” without noticing.
