Zeke, a 777 being flown by an opperator has never lost two engines during flight. Ever.
It was within the last 12 month after takeoff out of WMKK by MH
. The aircraft turned back and landed at the airport with a glide approach. My understanding it was a computer/electronics problem, not a mechanical one, occurred when they went from takeoff thrust and reduced to climb.
The engines failed to continue to produce the commanded climb power, do not jump to the conclusion that a loss of power means a mechanical failure fire or failure. I don't know if the rolled back to idle or shutdown.
Airlines in Asia know about the incident, and its part of the current simulator profile in Asia with some airlines, including the worlds largest 777 operator that is based in aSIA. The current profile involves a turn back after takeoff for a glide approach.
As it was a Malaysian registered aircraft, incident occurred in Malaysia, only the Malaysian DCA
needs to be involved with the investigation.
This is second serious incident involving a 777 for MH
in the past year, accident and incident reports in Asia are not widely available as most parts in the western world. You only know about the other one as it did not happen in Malaysia.
Rollbacks have occurred with many engine types, both FADEC and non FADEC. Examples of four engine rollbacks include British Airways 747 with loss of 4 engines in flight due to volcanic ash over Indonesia, and Ansett BAe-146 4 engine rollback in cruise due to high bleed demand for engine and wing anti ice at high altitude. A number of 717 rollbacks have occurred in Australia over the last few years.
