Nothing about Italy and justice from my side.Only some words about ATR ,maintenance and the crew.
There was no reason to replace the indicator asap.The report is showing there are only 4 digits u/s-this means it was an ongoing problem because digits are failing one after the other over a long period.The calculation of the amount of fuel is not affected and a second indication (repeater) is available as well.
So a MEL release for at least 3 days is no problem.(may be it is a 10 days
item)
Sufficient time to order a correct part number.
Now we have the engineer with the wrong part ordered by another engineer.Bad situation-no doubt.
First thing at my type course regarding chapter 28 was:be carefull,there are indicators showing/calculating with LBS or KG and 42 or 72 options as well.All engineers i know are aware of this problem.
At each replacement of this indicator you have to compare the old and the new amount of fuel.Due to a lot problems with fuel indication on older ATR (the crashed one had more than 30.000 cycles) fuel indicator replacement is very often a part of t/s to eliminate the origin of the problem.I'm sure the guy did not changed this part for the first time,
but he learned nothing...
And the crew:i never met a crew accepting an aircraft with a split more than 100 kg during refueling !this crew received the aircraft with nearly to
tons more indicated than reported in the log.And they refueled it twice with a split of nearly 50%.Unbelievable !
It is a 10 minuit job to confirm the correct aount of fuel with the sticks !
So for me a combination of very very poor maintenance and a crew who had the wrong job.
