Flight Crew Diverted; General Maintenance Action
Aircraft
After take off and approximately arriving at cruise; EICAS displayed 'L PACK TEMP.' While performing the QRH procedure the EICAS displayed 'L PACK OFF.' The QRH procedure did not restore the left pack. Via SATCOM we spoke in conference with our Dispatcher and Maintenance. Under Maintenance direction we attempted to restore the left pack. The left pack came back on briefly but then quickly displayed 'L PACK TEMP' followed by 'L PACK OFF.' Due to the requirement to remain within 1 hour of an airport during single pack operation; ETOPS was no longer possible. Dispatch suggested [a nearby airport] as the best airport to land. After burning fuel to below the maximum landing weight we landed without incident. Maintenance applied the proper MEL and we were dispatched on a route to keep us within 1 hour of an airport.
B767-200 Captain reported left pack failed after reaching cruise altitude on a transoceanic flight. Aircraft diverted to nearby airport to plan a different route in compliance with MEL.
