There is no evidence of gross pilot's incompetence. Only limited data has been released and certainly nothing anywhere near sufficient to fully understand what happened to an experienced crew
On Feb 6th 2015 Taiwan's ASC reported that the investigation so far determined from flight data and cockpit voice recorders: the aircraft received takeoff clearance at 10:51L, in the initial climb the aircraft was handed off to departure at 10:52:33L. At 10:52:38L at about 1200 feet MSL, 37 seconds after becoming airborne, a master warning activated related to the failure of the right hand engine, at 10:52:43L the left hand engine was throttled back and at 10:53:00L the crew began to discuss engine #1 had stalled. At 10:53:06L the right hand engine (engine #2) auto-feathered. At 10:53:12L a first stall warning occured and ceased at 10:53:18L. At 10:53:19L the crew discussed that engine #1 had already feathered, the fuel supply had already been cut to the engine and decided to attempt a restart of engine #1. Two seconds later another stall warning activated. At 10:53:34L the crew radioed "Mayday! Mayday! Engine flame out!", multiple attempts to restart the engines followed to no avail. At 10:54:34L a second master warning activated, 0.4 seconds later both recorders stopped recording.
Is this data limited enough to believe incompetence....please look at the facts.
The holes have aligned resulting in this tragedy, but what is frustrating is that there were signs of this happening years ago.
