Argentine Navy accident: A few contributory factors by the 3 crew members:
They shut down a perfectly servicable engine.
They mismanaged a 3 engine approach and landing.
They struck a fuel bowzer on the go-around from the approach, taking out the left main gear, it's hydraulic fluid and shearing the coordinator on that engine.
In the final approach they e-handled the 3 remaining engines in the flare. Number 2 wouldn't feather and remained at around 75% power. Hydraulics were lost as B bus only remained powering a hydraulic system with no fluid. No one thought to de-boost before the approach, or to turn fuel and ignition off on the number 2 engine.
The aircraft climbed away on one engine, no hydraulics, not de-boosted, below safety speed, rolled and crashed.
They all walked away; a measure of the strenth of the Electra.
There is nothing to suggest that 2 crew in the same situation could have made any more mistakes than did 3!
