The NTSB's narrative final · quoted from the NTSB record
THE FLIGHT CREW EXPERIENCED THE PARTIAL POWER LOSS OF THREE OF FOUR ENGINES WHILE IN CRUISE FLIGHT. THE AIRPLANE WAS OPERATING IN ICING CONDITIONS WITH ALL AIRPLANE ANTI ICE SYSTEMS ON. THE FLIGHT PASSED THROUGH AN AREA OF RAPIDLY WARMING AIR AND THE ENGINE BLEED BANDS WERE OPEN AND COULD NOT BE CLOSED WITH THROTTLE MOVEMENT. THE CREW SHUT DOWN TWO ENGINES TO PREVENT OVERTEMP CONDITIONS AND REDUCED ONE TO IDLE. THEY DECLARED AN EMERGENCY AND DIVERTED TO AN AIRPORT NEARBY. SUBSEQUENT TESTING OF A LIKE AIRPLANE REVEALED THAT THE ENGINE DESIGN WAS SUCH THAT WHEN OPERATING AT HIGH ALTITUDE WITH ALL ANTI ICE SYSTEMS 'ON' THE BLEED AIR VALVES COULD NOT BE CLOSED WITH NORMAL PROCEDURES. THE MANUFACTURER SUBSEQUENTLY DEVELOPED A MODIFIED CHECKLIST TO CORRECT FOR THIS SITUATION.
