The “M” part of MEL isn’t always the case. Many, many operators use the MEL as a starting point from which they seek exemptions...but that’s probably not the issue here. However, IF the MEL is being used to move an aircraft, then it means that the redundancy is no longer in place and the loss of further equipment may be cause for concern. For instance, you can fly with one of the fire detection loops inside an engine on the blink. If the other one fails...
From what I’ve read, there were maintenance issues with unreliable airspeed indication from the previous day, then this other “engine” issue that has been reported that delayed departure.
Hate to broadbrush, but some non western countries rely on the automation draw more than we do elsewhere, where we do a lot of “automation failed/off” training, which goes back to fundamentals of pitch and power. With either of the above issues, HAND FLYING SKILLS ARE PARAMOUNT, so I hope against hope that lack of basic flying skills wasn’t the issue. Then again, I fly that aircraft, so I hope it wasn’t a serious mechanical issue, either!
Coincidentally, I’m off to do my 9 month simulator training today for the next few days, so I’m sure there will be some talk about this crash. I’ll let you know if I hear anything of substance.
